 ## Notes
 
 - **Mypy is gradual**: strict only for `lerobot.envs`, `lerobot.configs`, `lerobot.optim`, `lerobot.model`, `lerobot.cameras`, `lerobot.motors`, `lerobot.transport`. Add type annotations when modifying these modules.
-- **Imports**: prefer top-level imports; relative (`from .sibling import X`) across sibling files within a module, absolute (`from lerobot.module import X`) across modules.
-- **Optional dependencies**: many policies, envs, and robots are behind extras (e.g., `lerobot[aloha]`, see `pyproject.toml`). Guard optional imports with `TYPE_CHECKING or _foo_available` at module top + a `require_package(...)` check at use time. Reuse the `_foo_available` flags in `utils/import_utils.py`; don't call `is_package_available`.
+- **Optional dependencies**: many policies, envs, and robots are behind extras (e.g., `lerobot[aloha]`). New imports for optional packages must be guarded or lazy. See `pyproject.toml [project.optional-dependencies]`.
 - **Video decoding**: datasets can store observations as video files. `LeRobotDataset` handles frame extraction, but tests need ffmpeg installed.
 - **Prioritize use of `uv run`** to execute Python commands (not raw `python` or `pip`).

 Fortunately, being an open-source project, the community can also help by reporting and fixing vulnerabilities. We appreciate your efforts to responsibly disclose your findings and will make every effort to acknowledge your contributions.
 
+## Reporting a Vulnerability
+
+To report a security issue, please use the GitHub Security Advisory ["Report a Vulnerability"](https://github.com/huggingface/lerobot/security/advisories/new) tab.
+
+The `lerobot` team will send a response indicating the next steps in handling your report. After the initial reply to your report, the security team will keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.
+
+#### Hugging Face Security Team
+
+Since this project is part of the Hugging Face ecosystem, feel free to submit vulnerability reports directly to: **[security@huggingface.co](mailto:security@huggingface.co)**. Someone from the HF security team will review the report and recommend next steps.
+
+#### Open Source Disclosures
+
+If reporting a vulnerability specific to the open-source codebase (and not the underlying Hub infrastructure), you may also use [Huntr](https://huntr.com), a vulnerability disclosure program for open source software.
+
 ## Supported Versions
 
-Currently, we treat `lerobot` as a rolling release. We prioritize security updates for the latest available version (`main` branch). Please reproduce on the current head before reporting — we do not backport fixes to older releases.

+## Secure Usage Guidelines
 
-Report privately — **do not open a public issue or PR for a suspected vulnerability.**
-
-To report a security issue, please use the GitHub Security Advisory ["Report a Vulnerability"](https://github.com/huggingface/lerobot/security/advisories/new) tab. This routes to the maintainers, keeps the report private until a fix is ready, and lets us issue a CVE through GitHub if warranted. The `lerobot` team will send a response indicating the next steps in handling your report. We acknowledge valid, in-scope reports and will keep you updated on remediation. Please give us a reasonable window to fix before any public disclosure.

-## What your report must include
-
-We receive a high volume of reports. To be triaged, a report **must** follow the structure below. Copy this block into your submission and fill in every field. Reports missing the version, the proof of concept, or the impact are returned as incomplete and are not investigated until provided.
-
-```markdown
-### Summary
-
-One sentence: what the vulnerability is and where.
-
-### Affected version / commit
-
-Exact released version or commit SHA you reproduced on (e.g. v4.57.0 / a1b2c3d).
-Not "latest" or "main".
-
-### Affected component
-
-The public API, module, or entry point involved (e.g. `AutoModel.from_pretrained`).
-
-### Vulnerability class
-
-Type and CWE if known (e.g. deserialization / CWE-502, path traversal / CWE-22).
-
-### Attack vector & preconditions
-
-- How is the vulnerable code reached? (which API call / input / config)
-- Who is the attacker and what do they control?
-- What must be true for the attack to work? (auth, a user action, a non-default
-  setting, a malicious file being loaded, etc.)
-
-### Proof of concept
-
-A minimal, self-contained script or step sequence that runs on a clean install
-of the version above. Include:
-
-- the exact commands / code to run,
-- any input files needed (attach them, or give a script that generates them),
-- the **expected** behavior vs. the **actual** behavior you observed.
-  A snippet showing that a function _exists_ or _could_ be misused is not a PoC.
-
-### Impact
-
-What an attacker gains in a realistic deployment. "Could theoretically…"
-without a working chain is not an impact.
-
-### Scope
-
-Which trust boundary (see below) does this cross? If your finding touches
-anything in the "Out of scope" list, name which item and explain why it is
-nonetheless a violation of a guarantee we make.
-
-### Suggested severity (optional)
-
-We assign the final severity. Include a CVSS v3.1 vector only if you have one.
-
-### Suggested fix (optional)
-```
-
-> [!NOTE]
-> The bar is a **reproducible PoC against a supported version, with a concrete impact that crosses a trust boundary we actually defend** (see scope below). Reports that are theoretical, auto-generated by a scanner or LLM, or that restate documented behavior will be closed without detailed review.

-## Threat model & trust boundaries
-
-`lerobot` is tightly coupled to the Hugging Face Hub for sharing data and pretrained policies. When downloading artifacts uploaded by others, you expose yourself to risks. Please read below for recommendations to keep your runtime and robot environment safe. We _will_ treat as a vulnerability anything that breaks one of these protections — e.g. code executing despite `safetensors`-only loading, or a pinned revision being bypassed.
+`lerobot` is tightly coupled to the Hugging Face Hub for sharing data and pretrained policies. When downloading artifacts uploaded by others, you expose yourself to risks. Please read below for recommendations to keep your runtime and robot environment safe.
 
 ### Remote Artefacts (Weights & Policies)
 
-Models and policies uploaded to the Hugging Face Hub come in different formats. We heavily recommend uploading and downloading models in the [`safetensors`](https://github.com/huggingface/safetensors) format. `safetensors` was developed specifically to prevent arbitrary code execution on your system, which is critical when running software on physical hardware/robots. To avoid loading models from unsafe formats (e.g., `pickle`), you should ensure you are prioritizing `safetensors` files.

 ### Remote Code
 
-Some models or environments on the Hub may require `trust_remote_code=True` to run custom architecture code. Please **always** verify the content of the modeling files when using this argument. We recommend setting a specific `revision` (commit hash) when loading remote code to ensure you protect yourself from unverified updates to the repository.

-## In scope
-
-We treat as vulnerabilities issues in the **published package code** — the library's own API surface — that an attacker can trigger without the victim having opted into a documented risk. For example:
-
-- code execution, memory corruption, or file access reachable through a normal API call on input that is **not** an untrusted model/artifact the user chose to load;
-- a control we advertise being bypassed (e.g. code running despite `safetensors`-only loading, or a pinned revision being ignored);
-- exposure or mishandling of credentials, tokens, or another user's data by the library;
-- a real escape from a backend we document as a sandbox;
-- CI/CD or supply-chain issues in this repository.
-
-## Out of scope
-
-The following are **not** treated as vulnerabilities in `lerobot`. If your finding touches one of these, the report must explain why it is nonetheless a violation of a guarantee we make — otherwise it will be closed.
-
-- Issues that require loading an untrusted artifact and amount to the documented load-time risk above (code execution / file access on load of a malicious model, dataset, config, or pickle).
-- Findings in `examples/`, documentation, tests, or other non-packaged reference material.
-- Local denial-of-service from feeding pathological input to a function on your own machine (high memory, slow parse, panic), absent a multi-tenant or remote-service impact.
-- Model behavior: jailbreaks, alignment failures, prompt injection, or harmful generations. Model weights are authored by their uploaders; report these to the model owner.
-- Vulnerabilities in third-party dependencies we do not vendor — report upstream (we'll bump once fixed).
-- Theoretical issues without a working proof of concept, and reports auto-generated from scanners or LLMs without a verified, reproducible chain.
-- Best-practice or hardening suggestions with no demonstrated impact — missing email-authentication or transport records (MTA-STS, TLS-RPT, DMARC/SPF tuning), missing HTTP security headers, TLS configuration preferences, and similar scanner or config-checker output presented without a working exploit chain.
-
-## Safe harbor
-
-Good-faith research that respects these guidelines, avoids privacy violations and service disruption, and gives us a reasonable disclosure window will not be pursued by us. Do not access data that isn't yours and do not run tests against Hugging Face production infrastructure.

 LeRobot uses `PolicyProcessorPipeline`s to normalize inputs and de-normalize outputs around your policy.

-Pay close attention here: processors are the most common reproducibility pain point. A mismatch in normalization mode (`IDENTITY` vs `MEAN_STD` vs `MIN_MAX` vs `QUANTILES`/`QUANTILE10`) or in which features get normalized will train and eval without erroring, yet silently wreck results. Make sure the modes match how the checkpoint was trained, that the required stats exist (e.g. `QUANTILES` needs `q01`/`q99`), and that the pre- and post-processors stay consistent.

-### Avoid copying a modeling file — subclass it
-
-If your policy needs to modify a backbone that already exists in `transformers` (custom conditioning, extra inputs, a swapped sub-module), **do not vendor a copy of its `modeling_*.py`**. Instead, subclass the smallest upstream unit and override only what changes. [`pi_gemma.py`](https://github.com/huggingface/lerobot/blob/main/src/lerobot/policies/pi_gemma.py) is the canonical reference: it injects AdaRMS conditioning into PaliGemma/Gemma in ~370 lines by subclassing `GemmaModel`/`PaliGemmaModel` and overriding the decoder-layer forward, instead of forking the ~2,000-line modeling file. Model surgery on a _loaded_ native model is also fine (layer truncation, tokenizer expansion, hidden-state capture — see `evo1/internvl3_embedder.py`, `eo1/modeling_eo1.py`, `groot/groot_n1_7.py` for working examples). Reviewers will ask for this pattern when a PR arrives with a copied modeling file; the only accepted exception is a model that does not exist in `transformers` at all.

-# EVO1
-
-EVO1 is a Vision-Language-Action policy for robot control built around an InternVL3 backbone and a continuous flow-matching action head. This LeRobot integration exposes EVO1 as a standard policy type so it can be trained and evaluated with the usual LeRobot dataset, checkpoint, and processor APIs.
-
-## Model Overview
-
-The policy embeds one or more camera images and the language task prompt with InternVL3, pads robot state/action vectors to fixed maximum dimensions, and predicts future action chunks with a flow-matching action head. During inference, the policy samples an action chunk and returns `n_action_steps` actions from that chunk before sampling again.
-
-### What the LeRobot Integration Covers
-
-- Standard `policy.type=evo1` configuration through LeRobot
-- InternVL3 image/text embedding with optional FlashAttention fallback
-- Stage-based finetuning controls for action-head-only and VLM finetuning runs
-- Continuous flow-matching action prediction
-- Checkpoint save/load through LeRobot policy APIs
-- Training with `lerobot-train` and evaluation with standard policy inference APIs
-
-The broader EVO1 project may include additional training scripts and dataset tooling. This page focuses on the LeRobot robot-control policy path.
-
-## Installation Requirements
-
-1. Install LeRobot by following the [Installation Guide](./installation).
-2. Install EVO1 dependencies:
-
-   ```bash
-   pip install -e ".[evo1]"
-   ```
-
-   For LIBERO evaluation, install the LIBERO extra as well:
-
-   ```bash
-   pip install -e ".[evo1,libero]"
-   ```
-
-3. Install a `flash-attn` wheel only if it is compatible with your Python, PyTorch, CUDA, and GPU stack. EVO1 falls back to standard attention when `flash_attn` is not available.
-
-EVO1 uses the native Hugging Face `transformers` InternVL implementation, so `policy.vlm_model_name` must point to a natively converted checkpoint such as `OpenGVLab/InternVL3-1B-hf` (note the `-hf` suffix). The first run may download the configured VLM checkpoint unless `policy.vlm_model_name` points to a local model directory.
-
-## Data Requirements
-
-EVO1 expects a LeRobot dataset with:
-
-- One to `policy.max_views` visual observations, for example `observation.images.image`
-- `observation.state`
-- `action`
-- A language task instruction in the dataset `task` field, or another field configured with `policy.task_field`
-
-State and action vectors are padded to `policy.max_state_dim` and `policy.max_action_dim`. Predictions are cropped back to the dataset action dimension before being returned.
-
-## Usage
-
-To use EVO1 in a LeRobot configuration, specify:
-
-```python
-policy.type=evo1
-```
-
-By default, a new EVO1 policy initializes its VLM from:
-
-```python
-policy.vlm_model_name=OpenGVLab/InternVL3-1B-hf
-```
-
-Once a LeRobot-format EVO1 checkpoint is available, load it with:
-
-```python
-policy.path=your-org/your-evo1-checkpoint
-```
-
-## Training
-
-### Stage 1
-
-Stage 1 freezes the VLM and trains the action head:
-
-```bash
-lerobot-train \
-  --dataset.repo_id=your_org/your_dataset \
-  --policy.type=evo1 \
-  --policy.training_stage=stage1 \
-  --policy.vlm_model_name=OpenGVLab/InternVL3-1B-hf \
-  --policy.device=cuda \
-  --policy.chunk_size=50 \
-  --policy.n_action_steps=50 \
-  --policy.max_state_dim=24 \
-  --policy.max_action_dim=24 \
-  --policy.optimizer_lr=1e-5 \
-  --batch_size=4 \
-  --steps=5000 \
-  --output_dir=./outputs/evo1_stage1
-```
-
-### Stage 2
-
-Stage 2 finetunes the VLM branches and action head. A common workflow starts from a Stage 1 checkpoint:
-
-```bash
-lerobot-train \
-  --dataset.repo_id=your_org/your_dataset \
-  --policy.path=./outputs/evo1_stage1/checkpoints/005000/pretrained_model \
-  --policy.training_stage=stage2 \
-  --policy.vlm_model_name=OpenGVLab/InternVL3-1B-hf \
-  --policy.device=cuda \
-  --policy.chunk_size=50 \
-  --policy.n_action_steps=50 \
-  --policy.max_state_dim=24 \
-  --policy.max_action_dim=24 \
-  --policy.optimizer_lr=1e-5 \
-  --batch_size=4 \
-  --steps=80000 \
-  --output_dir=./outputs/evo1_stage2
-```
-
-By default, `policy.training_stage` reapplies the finetuning defaults for that stage. This is important when
-starting Stage 2 from a Stage 1 checkpoint, because the Stage 1 checkpoint config stores the VLM finetuning
-flags as disabled. These stage defaults take precedence over saved or manually supplied `policy.finetune_*`
-flags unless `policy.apply_training_stage_defaults=false`, so set that flag only when manually controlling
-every finetuning flag.

-  --inference.type=rtc \ # optional

-## Results
-
-### LIBERO Evaluation
-
-> [!NOTE]
-> Benchmark results for a `lerobot`-hosted LIBERO checkpoint trained with this implementation
-> will be added once training completes.
-
-The official EVO1 LIBERO rollout protocol uses the raw LIBERO camera feature names
-(`observation.images.agentview_image` and `observation.images.robot0_eye_in_hand_image`), replans every
-14 actions, and binarizes the gripper command before stepping the simulator. The EVO1 policy postprocessor
-can crop the padded 24D action back to the 7D LIBERO action space and apply that gripper binarization. To
-evaluate a LIBERO checkpoint under the same one-episode-per-task setting, keep the raw camera names instead
-of the default `image`/`image2` mapping and set the LIBERO action postprocessing flags:
-
-```bash

-# FastWAM
-
-FastWAM is a World Action Model policy for robot control. The LeRobot integration exposes FastWAM through the standard policy API so it can be configured with `policy.type=fastwam`, trained with `lerobot-train`, and loaded through the LeRobot pretrained policy interface.
-
-## Model Overview
-
-FastWAM keeps video modeling during training, but uses direct action prediction at inference time instead of iteratively generating future observations. This LeRobot policy wraps the FastWAM action model, adapts LeRobot batches to FastWAM training samples, and provides the standard processor pipeline for normalization and action postprocessing.
-
-The implementation initializes the visual world-model components from `Wan-AI/Wan2.2-TI2V-5B` by default and predicts action chunks with shape `[batch, action_horizon, action_dim]`.
-
-### What the LeRobot Integration Covers
-
-- Standard `policy.type=fastwam` configuration through LeRobot
-- Image, state, action, and language-task batch adaptation
-- Action chunk inference through `select_action` and `predict_action_chunk`
-- Checkpoint save/load through the LeRobot policy APIs
-- Configurable LIBERO gripper action postprocessing
-
-## Installation Requirements
-
-Install LeRobot from source, then install FastWAM dependencies:
-
-```bash
-pip install -e ".[fastwam]"
-```
-
-This installs the FastWAM policy extra from `pyproject.toml`: `transformers`,
-`diffusers`, `ftfy`, and `regex`, plus LeRobot's base dependencies.
-
-For LIBERO evaluation, install the benchmark dependencies too:
-
-```bash
-pip install -e ".[fastwam,libero]"
-```
-
-This installs both extras. In addition to the FastWAM dependencies above, the
-`libero` extra installs LeRobot dataset dependencies, `hf-libero` on Linux, and
-`scipy`.
-
-FastWAM uses the Wan2.2 TI2V backbone. The default model id is:
-
-```python
-policy.model_id=Wan-AI/Wan2.2-TI2V-5B
-```
-
-## Data Requirements
-
-FastWAM expects a LeRobot dataset with:
-
-- one or more visual observations whose widths concatenate to `policy.image_size[1]`
-- `observation.state` when `policy.proprio_dim` is not `None`
-- `action`
-- a language task instruction through the dataset task field, or precomputed `context` and `context_mask` tensors
-
-The default visual setup is one image feature named `observation.images.image` with shape `(3, 224, 448)`. If the dataset uses two cameras, configure `policy.input_features` so their heights match `224` and their widths sum to `448`.
-
-## Usage
-
-Create a new FastWAM policy with:
-
-```bash
-lerobot-train \
-  --dataset.repo_id=your-org/your-dataset \
-  --policy.type=fastwam \
-  --policy.action_dim=7 \
-  --policy.proprio_dim=8 \
-  --policy.action_horizon=32 \
-  --policy.n_action_steps=10 \
-  --policy.image_size='[224,448]' \
-  --output_dir=./outputs/fastwam_training \
-  --job_name=fastwam_training \
-  --steps=300000 \
-  --batch_size=8 \
-  --policy.device=cuda
-```
-
-Evaluate an existing LeRobot-format checkpoint on LIBERO-10 with:
-
-```bash
-lerobot-eval \
-  --policy.path=ZibinDong/fastwam_libero_uncond_2cam224 \
-  --policy.device=cuda \
-  --policy.torch_dtype=float32 \
-  --policy.n_action_steps=10 \
-  --env.type=libero \
-  --env.task=libero_10 \
-  --env.observation_height=224 \
-  --env.observation_width=224 \
-  --eval.batch_size=1 \
-  --eval.n_episodes=50 \
-  --seed=0 \
-  --env.episode_length=600
-```
-
-For `libero_goal`, `libero_spatial`, and `libero_object`, use
-`--env.episode_length=300`.
-
-For real-robot rollout, use the same checkpoint path:
-
-```bash
-lerobot-rollout \
-  --robot.type=so101_follower \
-  --robot.port=/dev/ttyACM0 \
-  --policy.path=your-org/fastwam-real-robot
-```
-
-## Configuration Notes
-
-### Image Features
-
-`policy.image_size` is the size of the concatenated FastWAM image tensor as `(height, width)`. Each configured image feature must have shape `(3, height, camera_width)`, and all camera widths must sum to the configured width.
-
-### Action Chunking
-
-`policy.action_horizon` controls the number of future actions supervised during training and predicted during inference. `policy.n_action_steps` controls how many actions are consumed before the policy predicts a fresh chunk. `policy.n_action_steps` must be less than or equal to `policy.action_horizon`.
-
-### Wan Components
-
-FastWAM loads the Wan VAE, video DiT, text encoder, and tokenizer from the configured Wan model directory or Hugging Face Hub model id. LeRobot-format FastWAM checkpoints saved by `save_pretrained` also copy the local Wan component files needed by `from_pretrained`.
-
-### Attention Backend
-
-FastWAM's DiT uses PyTorch's `scaled_dot_product_attention` (SDPA) for all attention. It does **not** use FlashAttention: its Mixture-of-Transformers (MoT) routing needs arbitrary boolean `[query, key]` attention masks, which the FlashAttention varlen API cannot express. Installing the `flash-attn` package therefore has no effect on the FastWAM path. (Note that SDPA itself may still select PyTorch's own flash / memory-efficient / math kernel internally — this is unrelated to the `flash-attn` package.)
-
-### LIBERO Action Toggle
-
-FastWAM LIBERO checkpoints use `policy.toggle_action_dimensions=[-1]` by
-default to match the gripper action convention used by the original FastWAM
-evaluation pipeline:
-
-```bash
---policy.toggle_action_dimensions='[-1]'
-```
-

-GR00T is an NVIDIA foundation model family for generalized humanoid robot reasoning and skills. It is a cross-embodiment policy that accepts multimodal input, including language, images, and proprioception, to perform manipulation tasks in diverse environments.
+GR00T N1.5 is an open foundation model from NVIDIA designed for generalized humanoid robot reasoning and skills. It is a cross-embodiment model that accepts multimodal input, including language and images, to perform manipulation tasks in diverse environments.
 
-LeRobot integrates GR00T N1.7 through the `groot` policy type.

-> [!WARNING]
-> **Breaking change:** GR00T N1.5 support was removed from LeRobot, and current releases support GR00T N1.7 only. N1.5 checkpoints and configs are rejected with a migration note. To keep using an N1.5 checkpoint, pin the last release that supports it: `pip install 'lerobot==0.5.1'`. To use the current release, migrate to GR00T N1.7 (base model [`nvidia/GR00T-N1.7-3B`](https://huggingface.co/nvidia/GR00T-N1.7-3B)).
+This document outlines the specifics of its integration and usage within the LeRobot framework.
 
 ## Model Overview
 
-GR00T N1.7 uses a Cosmos-Reason2/Qwen3-VL backbone and provides checkpoints for SimplerEnv, DROID, and LIBERO.
+NVIDIA Isaac GR00T N1.5 is an upgraded version of the GR00T N1 foundation model. It is built to improve generalization and language-following abilities for humanoid robots.
 
-Developers and researchers can post-train GR00T with their own real or synthetic data to adapt it for specific humanoid robots or tasks.

-If your dataset exists only locally (not yet on the Hub), it is automatically pushed to a **private** Hub repo so the job can download it by `repo_id` (nothing is made public). The trained model is pushed to the model repo at the end of the run. To also push every intermediate checkpoint to the Hub as it is saved (so you can monitor progress mid-run), add `--save_checkpoint_to_hub=true` — this requires a runtime image that includes this feature.
+</hfoption>
+</hfoptions>
 
-Every job (and any dataset pushed by the run) is tagged `lerobot` so it's easy to find on the Hub. Add your own with `--job.tags '["my-tag"]'`.
+You can modify the `--flavor` to use different hardware, for example: `t4-small`, `a100-large`, `h200`. Use `hf jobs hardware` to see the full list with pricing.
+Depending on the model you want to train and the hardware you selected you can also modify the `--batch_size` and `--number_of_workers`.
+For longer training sessions increase the timeout.
 
-By default the job is capped at `2d` (48h) of wall-clock. Override it with an HF Jobs duration string, e.g. `--job.timeout=4h` to fail faster or `--job.timeout=7d` for a longer run.
+Once the training is started you can go to [Jobs](https://huggingface.co/settings/jobs) and see if your jobs is running as well as all the outputs. Sometimes it takes a few minutes to schedule your job so be patient.
 
-> **Note:** the model repo is created up front (it holds the staged training config the job runs from). If a run fails before the model is pushed, that repo is left on the Hub so you can inspect it — it is not deleted automatically, so repeated failures can leave empty repos behind. Remove one with `hf repo delete <repo-id>`.
-
-**Prerequisites:** run `hf auth login` before submitting. For Weights & Biases integration, run `wandb login` or set `WANDB_API_KEY` on your machine — the key is forwarded to the job automatically.
-
-**Resuming on a job.** Adding `--job.target` to a resume command runs the resume in the cloud — the same command works locally or remotely. The checkpoint repo is the source of truth, and new checkpoints continue the lineage in the same repo:
-
-```bash
-# resume a Hub run on a job (its checkpoints are already on the Hub)
-lerobot-train --config_path=${HF_USER}/my_policy --resume=true --job.target=a10g-small
-
-# resume a LOCAL run on a job — the checkpoint is uploaded to a private Hub repo first,
-# then the job resumes from it (a local-only dataset is uploaded the same way)
-lerobot-train \
-  --config_path=outputs/train/act_so101_test/checkpoints/last/pretrained_model/train_config.json \
-  --resume=true \
-  --job.target=a10g-small
-```
-
-Job settings come from the current command, so override `--job.target`, `--job.timeout`, etc. as needed; for the resumed run to itself be resumable later, keep `--save_checkpoint_to_hub=true`.
+After training the model will be pushed to hub and you can use it as any other model with LeRobot.

-The examples below load the model from `--policy.path`. To pin a specific pushed version — useful once `--save_checkpoint_to_hub=true` has committed several checkpoints — add `--policy.pretrained_revision` with a commit hash, branch, or tag. Each pushed checkpoint is tagged with its step (e.g. `--policy.pretrained_revision=010000`), so you can recover a checkpoint by step without looking up its commit sha.

 **State-of-the-art machine learning for real-world robotics**
 
-🤗 LeRobot provides a hardware-agnostic, Python-native interface for controlling real robots - from affordable arms like the SO-ARM101 to full humanoids. Plus the tools to record, store, and share the datasets they generate. Every dataset uses the standardized **LeRobotDataset** format (synchronized video + action/state data) and can be streamed directly from the [Hugging Face Hub](https://huggingface.co/lerobot).
+🤗 LeRobot aims to provide models, datasets, and tools for real-world robotics in PyTorch. The goal is to lower the barrier for entry to robotics so that everyone can contribute and benefit from sharing datasets and pretrained models.
 
-🤗 On top of that data, LeRobot implements state-of-the-art policies - from lightweight imitation-learning models like ACT to large vision-language-action models like π₀ and SmolVLA - all trainable, shareable, and deployable with the same handful of CLI commands.
+🤗 LeRobot contains state-of-the-art approaches that have been shown to transfer to the real-world with a focus on imitation learning and reinforcement learning.
 
-The goal: lower the barrier to entry for robotics, so that everyone can contribute to, and benefit from, shared datasets and pretrained models.
+🤗 LeRobot already provides a set of pretrained models, datasets with human collected demonstrations, and simulated environments so that everyone can get started.

-## How It Works
-
-**Teleoperate → Record → Train → Deploy**
-
-1. **Teleoperate** - control the robot yourself (with a leader arm, keyboard, or phone) so it can learn from your movements.
-2. **Record** - each demonstration is saved as a dataset: synchronized camera video plus the actions you took.
-3. **Train** - a policy (the neural network that will control the robot) learns to imitate your demonstrations.
-4. **Deploy** - run the trained policy on the robot and watch it complete the task on its own.

-## Common Problems
-
-Running into issues? A few of the most frequent ones:
-
-- **Blurry or unusable camera footage** - lighting matters more than resolution. See the [Cameras](./cameras) guide.
-- **Build or install errors** (`cmake`, `ffmpeg`, CUDA) - see the Troubleshooting section of the [Installation guide](./installation#troubleshooting).
-- **Not sure which policy fits your GPU** - check the [Compute & Hardware Guide](./hardware_guide).
-- **Still stuck?** Ask on [Discord](https://discord.gg/s3KuuzsPFb) - the community (and the LeRobot team) is there to help.

-# Isaac Teleop
-
-Control your robot with NVIDIA [Isaac Teleop](https://github.com/NVIDIA/IsaacTeleop), a
-multi-modal teleoperation framework. Isaac Teleop drives a single `TeleopSession` from a range
-of input devices — XR (VR) controllers, hand tracking, full-body tracking, Manus gloves, foot
-pedals, and more.
-
-In LeRobot, Isaac Teleop ships as a self-contained example under
-[`examples/isaac_teleop_to_so101/`](https://github.com/huggingface/lerobot/tree/main/examples/isaac_teleop_to_so101).
-Each Isaac Teleop input device is its own `Teleoperator` subclass in the example's
-`isaac_teleop` package, sharing one session lifecycle (see `IsaacTeleopTeleoperator`). The
-devices available today are the **XR controller** (`XRController`) and a back-drivable
-**SO-101 leader arm** (`SO101LeaderArm`); Manus gloves and hand/full-body tracking are the
-natural next devices. This guide focuses on the XR controller; the SO-101 leader is summarized
-under [Run the example](#step-3-run-the-example).
-
-**In this guide you'll learn:**
-
-- How an Isaac Teleop device drives a robot end‑effector (EE) target
-- How the _clutch_ (squeeze/grip on the XR controller) engages teleoperation without jerking the arm
-- How to run the SO‑101 teleoperation example and tune motion / gripper / IK
-
-## Installation
-
-The example lives in the LeRobot repository (it is not part of the `lerobot` pip package), so
-clone the repo and install from source. The canonical, always-up-to-date install and usage
-reference is the example's
-[`README.md`](https://github.com/huggingface/lerobot/tree/main/examples/isaac_teleop_to_so101/README.md);
-in short:
-
-```bash
-git clone https://github.com/huggingface/lerobot.git
-cd lerobot
-uv pip install -e ".[feetech,kinematics,dataset]" "huggingface_hub>=1.5"
-uv pip install "isaacteleop[cloudxr,retargeters-lite]~=1.3.131" "scipy>=1.14"
-```
-
-`isaacteleop` is published on public PyPI (Linux only). The `cloudxr` extra brings the CloudXR
-runtime bindings; `retargeters-lite` is the scipy-based retargeter path that resolves on both
-x86_64 and ARM (on aarch64 — e.g. a DGX Spark — the full `retargeters` extra does not resolve
-because of its `dex-retargeting`/`nlopt` pins, which is why it is not the default here). On
-x86_64 you can additionally install the full retargeter stack:
-
-```bash
-uv pip install "isaacteleop[retargeters]~=1.3.131"
-```
-
-### Set up CloudXR and connect a headset
-
-Isaac Teleop streams the headset to your machine over **NVIDIA CloudXR**, which provides the
-OpenXR runtime the session connects to. By default LeTeleop **auto-launches the CloudXR runtime
-for you** when you call `teleop_device.connect()` — you no longer have to run `python -m
-isaacteleop.cloudxr` and `source cloudxr.env` in a separate shell. All you need is a supported
-headset connected and the CloudXR firewall ports open. Follow the Isaac Teleop
-[Quick Start](https://nvidia.github.io/IsaacTeleop/main/getting_started/quick_start.html) for the
-headset-pairing and firewall details.
-
-**First run (EULA).** The very first launch must accept the NVIDIA CloudXR EULA. The auto-launch
-prompts for it **on stdin**, so on a headless machine it will hang waiting for input. Bootstrap
-the EULA once, interactively, with:
-
-```bash
-python -m isaacteleop.cloudxr --accept-eula   # one-time: accept the CloudXR EULA
-```
-
-After that, `connect()` launches the runtime non-interactively. The launch **blocks for ~30s**
-while the runtime comes up.
-
-**Configuration.** Two fields on `IsaacTeleopConfig` (shared by every device) control this:
-
-- `auto_launch_cloudxr` (default `True`) — whether `connect()` starts the runtime. Set `False`
-  when CloudXR is already running externally.
-- `cloudxr_env_file` (default `None`) — an optional CloudXR device-profile `.env` selecting the
-  headset transport (e.g. an Apple Vision Pro profile). This is launcher **input**; it is not the
-  `~/.cloudxr/run/cloudxr.env` **output** file the old manual flow told you to `source`. `None`
-  keeps the default auto-WebRTC profile — though the SO-101 example overrides it to the
-  `default.env` shipped next to `teleoperate.py` unless you pass `--teleop.cloudxr_env_file`.
-
-**Opting out.** To skip the auto-launch (CloudXR already running), either set
-`auto_launch_cloudxr=False` or export:
-
-```bash
-export LEROBOT_CLOUDXR_SKIP_AUTOLAUNCH=1
-```
-
-The **env var takes precedence over the config field**: if `LEROBOT_CLOUDXR_SKIP_AUTOLAUNCH=1` is
-set, the auto-launch is skipped even when `auto_launch_cloudxr=True`. This variable is
-**independent** of Isaac Lab's `ISAACLAB_CXR_SKIP_AUTOLAUNCH` — setting one does not affect the
-other.
-
-**One teleoperator per process.** The CloudXR runtime configures the environment process-wide (a
-singleton), so run a single Isaac Teleop teleoperator per process.
-
-**Shutting down.** Always call `teleop_device.disconnect()` on exit — including on Ctrl-C. Wrap
-your teleoperation loop in `try/finally` and call `disconnect()` in the `finally`. This tears down
-the OpenXR session **before** the CloudXR runtime, which is the required order; the launcher's
-`atexit` hook only reaps the runtime and does not run the session's `__exit__`, so without an
-explicit `disconnect()` an interrupted run shuts down in the wrong order.
-
-```python
-teleop_device.connect()
-try:
-    while True:
-        action = teleop_device.get_action()
-        # ... drive the robot ...
-finally:
-    teleop_device.disconnect()
-```
-
-See [System Requirements](https://nvidia.github.io/IsaacTeleop/main/references/requirements.html)
-for supported OS / GPU / CloudXR versions and headsets.
-
-## How it works
-
-The XR controller is one Isaac Teleop **input** device. `XRController` is a deliberately thin
-reader: it exposes the **raw** controller grip pose — already statically rebased into the robot
-base frame — plus the squeeze and trigger analog values. It has **no** retargeters and **no**
-clutch logic of its own. The clutch (engage latch + delta rebasing onto the EE) and the gripper
-mapping live downstream in the example loop, which then feeds LeRobot's existing closed‑loop
-Cartesian IK pipeline — the same one the phone teleoperator uses. The device‑specific pieces are
-`XRController`, the loop's `Clutch`, and `MapXRControllerActionToRobotAction`; everything downstream
-(`EEBoundsAndSafety`, `InverseKinematicsEEToJoints`) is shared, and a future device (e.g. Manus
-gloves) would swap in its own `teleop_<device>.py` + processor while reusing the rest.
-
-`XRController._build_pipeline` wires Isaac Teleop's `ControllersSource` — statically rebased into
-the robot base frame by the native `ControllerTransform` (`base_T_anchor`) — and exposes the
-transformed controller stream verbatim. `get_action()` reads the grip pose, squeeze, and trigger
-straight off it; the session is always stepped `RUNNING` (there is no clutch retargeter to gate).
-
-The `Clutch` class (in `examples/isaac_teleop_to_so101/isaac_teleop/clutch.py`, driven by the
-loop in `common.py`) mirrors Isaac Teleop's `SO101ClutchRetargeter`, but lives in-loop so the
-device can stay a thin reader:
-
-- It latches its engage origin on the squeeze **engage edge** (the frame the squeeze first crosses
-  `clutch_threshold`) and rebases both position and orientation around it, so engaging does not
-  teleport the arm. `Clutch.rebase` returns the absolute base-frame target as a `(pos, quat)`
-  pair, which the loop concatenates into the 7D `ee_pose` fed to the processor.
-- The analog trigger becomes a gripper `closedness` in `[0, 1]` (0 = open, 1 = closed),
-  proportional to the trigger pull, which `MapXRControllerActionToRobotAction` maps to a jaw target.

-### The clutch: owned by the example loop
-
-Unlike the phone pipeline (which splits the clutch across `MapPhoneActionToRobotAction` and
-`EEReferenceAndDelta`), the XR clutch lives entirely in the example loop's `Clutch` class. It emits
-an **absolute** EE pose, so there is no `EEReferenceAndDelta` stage and no delta accumulation in the
-processor — `MapXRControllerActionToRobotAction` is a pure, stateless per‑frame mapping.
-
-The clutch latches its engage origin on the squeeze **engage edge** (the moment the squeeze crosses
-`clutch_threshold`) and drives the EE from the motion _relative_ to that origin, so the arm does not
-teleport on engage. On **every** engage — startup and mid‑task re‑clutch alike — the home
-_position_ is latched from forward kinematics on the arm's **measured joints**, so the home equals
-where the arm physically is even if it moved while disengaged, and the engage is jump‑free. The
-home _orientation_ keeps the last commanded rotation: the 5‑DOF arm tracks orientation only
-softly, so latching the measured wrist orientation would inject its tracking offset into the
-command on every re‑clutch.
-
-## Controls
-
-- **Squeeze / grip** — the **clutch** (deadman). Hold it past `clutch_threshold` to engage
-  teleoperation; release to pause. Each engage re‑captures the origin, so you can reposition
-  your hand while paused and re‑engage without the arm jumping (index/clutch style).
-- **Trigger** — the **gripper**, controlled **analog**. The jaw tracks the trigger
-  proportionally — a half‑pressed trigger leaves the jaw half‑closed — via a closedness in
-  `[0, 1]` (0 = open, 1 = closed) that maps to an absolute gripper joint target.
-- **Controller orientation** — the **wrist**. The clutch rebases the controller orientation
-  (engage‑relative, base‑frame) into a soft IK orientation target the wrist tracks alongside
-  position. On the 5‑DOF SO‑101 the wrist follows the hand only partially by design — see
-  `orientation_weight` below.
-
-## Get started
-
-### Step 1: Create the teleoperator
-
-```python
-# Run from the repo root so the `examples` package is importable.
-from examples.isaac_teleop_to_so101.isaac_teleop import XRController, XRControllerConfig
-
-teleop_config = XRControllerConfig(
-    hand_side="right",      # "left" or "right" controller
-    clutch_threshold=0.5,   # squeeze value above which the clutch engages
-)
-teleop_device = XRController(teleop_config)
-```
-
-`XRController.get_action()` returns the **raw** base‑frame controller pose, not a clutch‑rebased
-target: `grip_pos` (3,) `[x, y, z]` [m] and `grip_quat` (4,) `[qx, qy, qz, qw]` in the robot base
-frame, plus scalar `squeeze` and `trigger` analog values in `[0, 1]`. The example loop's `Clutch`
-turns these into the absolute `ee_pose`, and the squeeze is thresholded by the loop against
-`clutch_threshold` to engage.
-
-### Step 2: Connect
-
-Calling `teleop_device.connect()` first auto-launches the CloudXR runtime (unless you opted out —
-see [Set up CloudXR and connect a headset](#set-up-cloudxr-and-connect-a-headset); this blocks for
-~30s and on the first run prompts for the EULA on stdin), then starts the Isaac Teleop
-[`TeleopSession`](https://nvidia.github.io/IsaacTeleop/main/getting_started/teleop_session.html)
-(opens the OpenXR session and discovers the controllers). XR controllers are self‑calibrating, so
-there is no manual calibration step — the clutch handles re‑centering each time you engage. Pair
-`connect()` with a `try/finally` that calls `disconnect()` so the session tears down before the
-runtime on exit/Ctrl-C.
-
-### Step 3: Run the example
-
-The example assumes you configured your robot (SO‑101 follower) and set the correct serial port.
-
-The **robot URDF and its meshes are fetched automatically** on first run: the XR device downloads
-the SO-101 URDF from the
-[`lerobot/robot-urdfs` Hugging Face bucket](https://huggingface.co/buckets/lerobot/robot-urdfs/tree/so101)
-into the LeRobot cache (`HF_LEROBOT_HOME/robot-urdfs/so101/`) and reuses it after, so there is no
-separate download step :
-
-```bash
-python -m examples.isaac_teleop_to_so101.teleoperate --robot.type=so101_follower --robot.port=/dev/ttyACM0 \
-    --robot.id=so101_follower_arm --teleop.type=xr_controller
-```
-
-The CLI is `lerobot-teleoperate`-style (draccus): `--robot.*` configures the SO-101 follower and
-`--teleop.type` selects the Isaac input device (`xr_controller` | `so101_leader`), with
-`--teleop.*` its device knobs. `--teleop.type=xr_controller` runs the XR-controller path described
-above. The startup safety contract: by default it slews all joints to a default reset pose over
-`--reset_duration` seconds (`--reset_to_origin=false` keeps the arm where it is), then seeds the
-clutch home from the arm's measured pose so the first engage is jump-free; the follower is
-commanded only while the clutch is engaged.
-
-**Customizing the reset pose.** The reset pose ships as a built-in default (a comfortable mid-range
-pose) and works out of the box — you do **not** need to record anything. To tailor it to your setup,
-back-drive the arm to the pose you want and run
-`python -m examples.isaac_teleop_to_so101.override_reset_pose --id <robot.id>`; it writes the
-current joints to a per-arm file in the LeRobot cache
-(`HF_LEROBOT_HOME/reset_poses/<robot.name>/<robot.id>.json`, keyed like calibration), which then takes
-priority over the built-in default on the next run. Because it lives in the user-local cache (not
-the repo), your override stays on your machine, and both `teleoperate` and `record` honor it
-when launched with the same `--robot.id`.
-
-The other device, `--teleop.type=so101_leader`, mirrors the follower 1:1 from a back-drivable
-SO-101 _leader arm_ whose joints are streamed by Isaac Teleop's native `so101_leader` plugin (no
-clutch, no IK — the leader and follower share the SO-101 kinematics).
-
-The `so101_leader_plugin` binary is a C++ plugin that is **not** part of the `isaacteleop` pip
-package — you build it from the Isaac Teleop source tree. Follow
-[Build Isaac Teleop from source](https://nvidia.github.io/IsaacTeleop/main/getting_started/build_from_source/index.html)
-(in short, from your Isaac Teleop checkout: `cmake -B build && cmake --build build --parallel &&
-cmake --install build`); the build installs the plugins under `<IsaacTeleop>/install/plugins/`, so
-the binary lands at `install/plugins/so101_leader/so101_leader_plugin` — the `--launch_plugin` path
-below. See the plugin's own `README.md` (next to the binary) for its serial/calibration details.
-
-Point `--teleop.port` at the physical leader's serial port and `--launch_plugin` at that plugin
-binary to have the script spawn it after CloudXR is up:
-
-```bash
-python -m examples.isaac_teleop_to_so101.teleoperate --robot.type=so101_follower --robot.port=/dev/ttyACM0 \
-    --robot.id=so101_follower_arm --teleop.type=so101_leader \
-    --teleop.port=/dev/ttyACM1 --teleop.id=so101_leader_arm \
-    --launch_plugin=/code/Teleop/install/plugins/so101_leader/so101_leader_plugin
-```
-
-(Note `so101_leader` here is the _Isaac_ leader, resolved against the Isaac Teleop device
-registry, distinct from `lerobot-teleoperate`'s serial `so101_leader`.) When a `--teleop.port` is
-set, the plugin's tick→radian calibration is inferred from `--teleop.id` and passed to the plugin
-as its third positional arg — the LeRobot-format JSON at
-`HF_LEROBOT_CALIBRATION/teleoperators/so_leader/<id>.json`, the same file the serial SO-101 leader
-uses (`lerobot-calibrate --teleop.type=so101_leader --teleop.id=<id>`). If it is missing the script
-warns and the plugin uses built-in defaults. Run `python -m examples.isaac_teleop_to_so101.teleoperate --help` for all flags. Its
-startup safety contract: by default the follower is
-slewed to the leader's first reading over `--align_duration` seconds (`--align=false` to skip) so
-the arm does not snap when the mirror begins, and while the leader stream is stale the follower is
-held at its measured pose.
-
-The URDF fetch uses `huggingface_hub` (already a LeRobot dependency) against the public
-`lerobot/robot-urdfs` bucket, so it needs no login. It is cached under
-`HF_LEROBOT_HOME/robot-urdfs/so101/`; delete that folder to force a re‑download.
-
-Then, in your headset: squeeze and hold the grip to engage, move the controller to drive the
-arm, twist/tilt it to orient the wrist, and press the trigger to close the gripper
-(proportionally — release to open).
-
-To record a dataset (not just teleoperate), use `record.py` in the same folder. It dispatches on
-`--teleop.type` (`xr_controller` | `so101_leader`) exactly like `teleoperate.py`, so either device
-can drive the follower, and it saves the commanded joints to a LeRobot dataset (`lerobot-record`-style
-`--dataset.*` flags). See its module docstring for the full CLI and the keyboard recording shortcuts.
-
-## Important pipeline steps and options
-
-The clutch already produces an absolute base‑frame pose, so the processor side is a thin
-**absolute‑pose** path — there is no frame remap, no delta accumulation, and no
-`EEReferenceAndDelta` stage.
-
-- `MapXRControllerActionToRobotAction` is a stateless per‑frame mapping from the device output to
-  the IK input contract. It writes the absolute base‑frame position, encodes the absolute
-  orientation as a rotvec target, and inverts the closedness into a motor gripper target:
-
-  ```python
-  action["ee.x"], action["ee.y"], action["ee.z"] = ee_pose[:3]   # absolute, base frame [m]
-  action["ee.wx"], action["ee.wy"], action["ee.wz"] = orient_rotvec  # orientation target (rotvec)
-  action["ee.gripper_pos"] = (1 - closedness) * 100   # motor units; SO-101 calibrates 100 = open
-  ```
-
-  The gripper polarity (`100 = open, 0 = closed`) is a hardware‑calibration convention in the source — flip it there if the jaw opens when it should close.
-
-- `EEBoundsAndSafety` clamps the EE to a workspace and rate‑limits per‑frame jumps. The clutch's
-  no‑teleport keeps frames small, so `max_ee_step_m` mostly catches transient controller tracking
-  glitches. The z floor is `0.0` (the table plane) so a stray target cannot drive the EE below the
-  table; x/y stay at the loose `[-1, 1]` m box. Set `raise_on_jump=False` so an over‑limit frame is
-  **clamped and warned** instead of raising — a crash mid‑loop would leave the arm uncontrolled:
-
-  ```python
-  EEBoundsAndSafety(
-      end_effector_bounds={"min": [-1.0, -1.0, 0.0], "max": [1.0, 1.0, 1.0]},
-      max_ee_step_m=0.10,
-      raise_on_jump=False,
-  )
-  ```
-
-- `InverseKinematicsEEToJoints(initial_guess_current_joints=False, orientation_weight=0.01)` solves
-  closed‑loop Placo IK. SO‑101 is a 5‑DOF arm, so the IK is position‑dominant; the small
-  `orientation_weight` lets it softly track the orientation target carried in `ee.w*` so the wrist
-  follows the hand, while the under‑determined roll stays partial by design. There is **no**
-  `GripperVelocityToJoint`: the absolute `ee.gripper_pos` is passed straight to `gripper.pos`.
-  `initial_guess_current_joints=False` warm‑starts each solve from the **previous IK solution**
-  rather than re‑seeding from the measured joints, so the joint trajectory stays continuous
-  frame‑to‑frame. Tune `orientation_weight` on hardware — too high fights position tracking, too
-  low ignores the orientation command.
-
-The example also gates safety at the loop level: after the startup reset slew (on by default —
-pass `--reset_to_origin=false` to keep the arm where it is), it commands the robot **only while
-the clutch is engaged**, and re‑sends the measured joints while disengaged, so releasing the
-clutch freezes the arm in place.
-
-See the [Processors for Robots and Teleoperators](./processors_robots_teleop) guide for more on
-adapting the pipeline to other robots.
-
-## Troubleshooting
-
-- **`ModuleNotFoundError: isaacteleop`** — the `isaacteleop` package is not installed in the
-  active environment. Re-run the install command at the top of this guide:
-  `uv pip install "isaacteleop[cloudxr,retargeters-lite]~=1.3.131"`.
-- **No controllers found** — make sure the CloudXR runtime is running, the firewall ports are
-  whitelisted, and the headset is connected (see
-  [Set up CloudXR and connect a headset](#set-up-cloudxr-and-connect-a-headset) and the Isaac
-  Teleop [Quick Start](https://nvidia.github.io/IsaacTeleop/main/getting_started/quick_start.html)).
-- **CloudXR auto-launch failed** — `connect()` raises a `RuntimeError` if the runtime does not

-# LingBot-VA
-
-LingBot-VA is an **autoregressive video-action world-model policy** built on the **Wan2.2**
-video-diffusion stack. It interleaves, in one autoregressive sequence, the prediction of
-future **video latents** and **robot actions** ("VA" = Video-Action). The LeRobot
-integration wires LingBot-VA into the standard training, evaluation and processor
-interfaces.
-
-## Model Overview
-
-LingBot-VA is a **dual-stream "mixture-of-transformers"**: a video/latent stream
-(`patch_embedding_mlp → blocks → proj_out`) and an action stream
-(`action_embedder → blocks → action_proj_out`) share the same 30 transformer blocks and
-text conditioning.
-
-| Component                | Class                   | Role                                                        |
-| ------------------------ | ----------------------- | ----------------------------------------------------------- |
-| DiT backbone (trainable) | `WanTransformer3DModel` | ~5B-param dual-stream transformer.                          |
-| VAE (frozen)             | `AutoencoderKLWan`      | Wan2.2 VAE, `z_dim=48`. Lazy-pulled from the source repo.   |
-| Text encoder (frozen)    | `UMT5EncoderModel`      | UMT5-XXL, `d_model=4096`. Lazy-pulled from the source repo. |
-
-At inference the policy runs an autoregressive loop per chunk: it denoises the video-latent
-stream (CFG, ~20 steps) and the action stream (~50 steps) with two independent
-flow-matching schedulers, maintaining a KV cache across chunks. Real observed keyframes are
-fed back into the KV cache as the chunk is executed (closed-loop world modeling).
-
-### What the LeRobot Integration Covers
-
-- Standard `policy.type=lingbot_va` configuration through LeRobot.
-- Ready-to-use LeRobot-format checkpoints on the Hub (converted from the released upstream ones).
-- Autoregressive dual-stream inference behind the standard `select_action` interface
-  (single-environment eval, `--eval.batch_size=1`).
-- Opt-in saving of the policy's **predicted (imagined) videos** during eval / training.
-- Evaluation with `lerobot-eval` on LIBERO and RoboTwin.
-- Training / fine-tuning via the dual-stream flow-matching loss (`policy.forward`), see below.
-
-## Installation
-
-1. Install LeRobot by following the [Installation Guide](./installation).
-2. Install the LingBot-VA extra:
-
-```bash
-pip install -e ".[lingbot_va]"
-```
-
-## Checkpoints
-
-The released upstream checkpoints have been converted to LeRobot format and pushed to the Hub:
-
-| Variant                | LeRobot checkpoint               |
-| ---------------------- | -------------------------------- |
-| LIBERO-Long post-train | `lerobot/lingbot_va_libero_long` |
-| RoboTwin post-train    | `lerobot/lingbot_va_robotwin`    |
-| Pretrained base        | `lerobot/lingbot_va_base`        |
-
-Only the trainable ~5B transformer is stored in the LeRobot
-`model.safetensors`. The frozen VAE + UMT5 + tokenizer (~20 GB) are pulled from
-`config.wan_pretrained_path` at load time (defaults to the source `robbyant/*` repo). The
-UMT5-XXL text encoder runs on CPU by default (`config.text_encoder_device`) so the 5B
-transformer + VAE fit on a single 24–32 GB GPU.
-
-## Evaluation (LIBERO)
-
-```bash
-lerobot-eval \
-    --policy.path=lerobot/lingbot_va_libero_long \
-    --policy.device=cuda \
-    --env.type=libero --env.task=libero_10 \
-    --env.observation_height=128 --env.observation_width=128 \
-    --eval.n_episodes=50 --eval.batch_size=1 \
-    --output_dir=outputs/eval/lingbot_va_libero
-```
-
-LingBot-VA's streaming inference (KV cache + observed-keyframe feedback) is implemented for
-single-environment eval; use `--eval.batch_size=1`.
-
-## Evaluation (RoboTwin)
-
-RoboTwin 2.0 needs the SAPIEN + CuRobo simulator stack. You can use the benchmark Docker image
-(`docker/Dockerfile.benchmark.robotwin`, which also needs `warp-lang==1.3.1` and CuRobo built
-with the GPU's compute capability in `TORCH_CUDA_ARCH_LIST`). RoboTwin uses **end-effector-pose
-control**, so run with `--env.action_mode=ee`: the policy predicts per-arm `xyz+quaternion+gripper`
-deltas (`robotwin_tshape` latent layout) that are composed onto the episode's initial eef pose and
-executed via CuRobo IK.
-
-```bash
-lerobot-eval \
-    --policy.path=lerobot/lingbot_va_robotwin \
-    --policy.device=cuda \
-    --env.type=robotwin --env.task=beat_block_hammer --env.action_mode=ee \
-    --eval.n_episodes=10 --eval.batch_size=1 \
-    --output_dir=outputs/eval/lingbot_va_robotwin
-```
-
-### Saving predicted (imagined) videos
-
-Set `--policy.save_predicted_video=true` to additionally VAE-decode the predicted video
-latents and write `pred_episode_*.mp4` next to the env-rendered `eval_episode_*.mp4` videos.
-The same flag works for the periodic eval during `lerobot-train`.
-
-## Training / fine-tuning
-
-`LingBotVAPolicy.forward(batch)` implements the dual-stream **flow-matching** loss
-(`latent_loss + action_loss`, timestep-weighted, action-masked) from the paper: it VAE-encodes
-the camera clips into video latents, UMT5-encodes the task, noises both streams, runs the
-transformer's block-causal training pass and returns `(loss, metrics)`. Optimizer preset is AdamW
-with a linear-warmup-then-constant schedule (matching upstream).
-
-Requirements:
-
-- The block-causal masks use PyTorch **flex-attention**, so build the policy with
-  `--policy.attn_mode=flex` for training (the default `torch` SDPA is inference-only).
-- The full 5B DiT does not fit a single 24–32 GB GPU under AdamW; fine-tune with **LoRA**
-  (`--policy.use_peft=true`) and/or optimizer offload. `get_optim_params` returns only the
-  trainable (e.g. adapter) parameters; the VAE + UMT5 text encoder stay frozen.
-
-```bash
-lerobot-train \
-  --policy.path=lerobot/lingbot_va_libero_long --policy.attn_mode=flex \
-  --policy.use_peft=true \
-  --dataset.repo_id=<your LeRobot-format dataset> \
-  --batch_size=1 --steps=... --output_dir=outputs/train/lingbot_va
-```
-
-The dataset must provide camera clips (a temporal window per camera, VAE-encoded to
-`frame_chunk_size` latent frames) and `frame_chunk_size * action_per_frame` action steps per item.
-
-## Data format (action channels & camera order)
-
-LingBot-VA is an **end-effector (Cartesian) pose** policy, it predicts EEF poses + gripper, not
-joint positions. Actions live in a fixed multi-embodiment **30-dim** layout; map your robot's
-action dimensions into these channels and pad the rest with `0` (`used_action_channel_ids` selects
-the channels a given checkpoint actually uses):
-
-| channels | meaning                                               |
-| -------- | ----------------------------------------------------- |
-| 0–6      | Left-arm end-effector pose                            |
-| 7–13     | Right-arm end-effector pose                           |
-| 14–20    | Left-arm joints (unused by the released checkpoints)  |
-| 21–27    | Right-arm joints (unused by the released checkpoints) |
-| 28       | Left gripper                                          |
-| 29       | Right gripper                                         |
-
-- **LIBERO** uses channels `0–6`: a 6-DoF EEF delta (xyz + rotation) + gripper (single arm).
-- **RoboTwin** uses channels `[0–6, 28, 7–13, 29]`: left EEF (xyz + quaternion) + left gripper +
-  right EEF + right gripper (16 dims). The env converts these poses to joint trajectories via
-  CuRobo IK — joints are never predicted.
-
-Joint-space datasets (or a different EEF convention) must be remapped into this schema before
-fine-tuning these checkpoints.
-
-**Camera order is fixed and order-sensitive**, per-camera latents are concatenated spatially in
-`obs_cam_keys` order, so the physical camera→slot mapping must match training:
-
-| benchmark | `obs_cam_keys` (in order)                                                                             | `camera_layout`                                                     |
-| --------- | ----------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------- |
-| LIBERO    | `observation.images.image` (agentview / 3rd-person), `observation.images.image2` (eye-in-hand wrist)  | `width_concat` (latents concatenated on width)                      |
-| RoboTwin  | `observation.images.head_camera`, `observation.images.left_camera`, `observation.images.right_camera` | `robotwin_tshape` (full-res head below, two half-res wrists on top) |
-
-The first camera is the exterior/head view and the rest are wrist views.
-

-## Notes
-
-- **Attention backend:** inference uses the `torch` SDPA backend (always available). The
-  `flashattn` and `flex` backends are optional; `flex` is only needed for training.
-- **Model size:** the DiT is ~5B params and the frozen VAE+UMT5 add ~20 GB; inference needs
-  roughly 18–24 GB of VRAM.

-## Hardware Deployment (lerobot-rollout)
-
-LeRobot-format checkpoints are available on the Hub for direct use with
-`lerobot-rollout`. Each checkpoint uses specific camera names that must
-match your robot's camera configuration.
-
-### Camera naming convention
-
-Each checkpoint expects specific `observation.images.*` keys.
-If your robot cameras have different names, use `--rename_map` to map them:
-
-| Checkpoint                    | Camera keys            | Description              |
-| ----------------------------- | ---------------------- | ------------------------ |
-| MolmoAct2-LIBERO-LeRobot      | `image`, `wrist_image` | LIBERO sim cameras       |
-| MolmoAct2-BimanualYAM-LeRobot | `top`, `left`, `right` | YAM 3-camera setup       |
-| MolmoAct2-DROID-LeRobot       | `cam0`, `cam1`         | External + wrist         |
-| MolmoAct2-SO100_101-LeRobot   | `cam0`, `cam1`         | Primary + secondary view |
-
-Example with an SO-100 robot using top and side cameras:
-
-```bash
-lerobot-rollout \
-  --policy.path=lerobot/MolmoAct2-SO100_101-LeRobot \
-  --rename_map='{"observation.images.top": "observation.images.cam0", "observation.images.side": "observation.images.cam1"}' \
-  --robot.type=so100_follower \
-  --robot.port=/dev/ttyACM0 \
-  --robot.cameras='{
-      top: {type: opencv, index_or_path: 0, width: 640, height: 480, fps: 30},
-      side: {type: opencv, index_or_path: 2, width: 640, height: 480, fps: 30}
-  }' \
-  --task="pick up the red cube" --duration=30
-```
-
-To use a wrist camera instead, just change the rename mapping:
-
-```bash
---rename_map='{"observation.images.top": "observation.images.cam0", "observation.images.wrist": "observation.images.cam1"}'
-```
-
-### Joint frame transform (SO-100/101 zero-shot)
-
-<Tip warning={true}>
-The MolmoAct2-SO100_101 checkpoint was trained on data that uses a different
-joint calibration convention than LeRobot >= 0.5.0. Without a frame
-correction, the arm may move in the wrong direction.
-
-This affects both **zero-shot deployment** and **fine-tuning** from the
-original checkpoint. The pretrained weights expect the old convention, so
-all joint data (observations and actions) must be transformed to match.
-
-The converted LeRobot checkpoint (`lerobot/MolmoAct2-SO100_101-LeRobot`)
-already includes this correction in its processor pipeline. If you convert
-or fine-tune the checkpoint yourself, set the following in the policy config (`configuration_molmoact2.py`):
-
-- `joint_signs`: `[1, -1, 1, 1, 1, 1]` (flips shoulder_lift direction)
-- `joint_offsets`: `[0, 90, 90, 0, 0, 0]` (shifts shoulder_lift and elbow_flex by 90°)
-
-See the [backward compatibility guide](./backwardcomp) for details on the
-calibration change.

-
-**`--policy.n_action_steps=10` and `--policy.empty_cameras=1` are explicit** because `--policy.pretrained_path` loads weights only — `lerobot/pi05_libero_base` stores both, and they would otherwise fall back to `50` and `0` (see [Loading a checkpoint](#loading-a-checkpoint)).
-
-Then evaluate a checkpoint with `lerobot-eval` and compare against the reference success rates — see [LIBERO](./libero).
-
-### Quantile statistics
-
-π₀.₅ normalizes `STATE` and `ACTION` with quantiles, so your dataset's `meta/stats.json` needs `q01` and `q99`. Older datasets carry only `min`/`max`/`mean`/`std` and fail on the first batch:
-
-```
-ValueError: QUANTILES normalization mode requires q01 and q99 stats
-```
-
-Recompute them:
-
-```bash
-lerobot-edit-dataset \
-    --repo_id your_dataset \
-    --new_repo_id your_dataset \
-    --operation.type recompute_stats \
-    --operation.overwrite true
-```
-
-**The result lands in `$HF_LEROBOT_HOME/your_dataset`**, not the cache `--dataset.repo_id` reads — so train with `--dataset.root=$HF_LEROBOT_HOME/your_dataset`, or add `--push_to_hub true` above.
-
-Or keep the dataset as-is and pass `--policy.normalization_mapping='{"ACTION": "MEAN_STD", "STATE": "MEAN_STD", "VISUAL": "IDENTITY"}'`.

-## Original-vs-LeRobot parity test
-
-`tests/policies/groot/test_groot_vs_original.py` verifies this LeRobot
-reimplementation of GR00T N1.7 (Qwen3-VL backbone + flow-matching action head)
-against NVIDIA's original `gr00t` package with two comparisons, each parametrized
-over every embodiment tag present in the checkpoint:
-
-1. **Model parity** — given byte-identical pre-processed inputs and the same
-   flow-matching seed (recorded in each artifact), both implementations must produce
-   the **same raw model output** (`get_action(...)["action_pred"]`, the normalized
-   flow-matching prediction). Output shapes must match exactly; any action-horizon
-   or action-dim mismatch fails the test.
-2. **Preprocessor parity** — given the identical raw observations (per-camera
-   frames, state vectors, language instruction), LeRobot's own preprocessor pipeline
-   (real Qwen3-VL chat template / tokenizer / image packing + checkpoint-driven
-   state normalization, no mocks) must produce the **same collated model inputs**
-   (`input_ids`, `attention_mask`, `pixel_values`, `image_grid_thw`, `state`,
-   `embodiment_id`) as the original package's processor.
-
-### Why two environments
-
-The original `gr00t` package pins `transformers==4.57.3` (Python 3.10); this
-integration requires `transformers>=5.x` (Qwen3-VL). Under 5.x, `PretrainedConfig`
-is itself a defaulted dataclass, so the original config dataclasses fail to import
-(`non-default argument follows default argument`). The two implementations therefore
-**cannot be imported in the same Python process**.
-
-So the test uses a **producer / consumer** split across two venvs:
-
-1. **Producer** — `tests/policies/groot/utils/dump_original_n1_7.py`, run in the _original_
-   gr00t venv. For each embodiment it builds dummy inputs generically from the
-   checkpoint metadata (state dims from `statistics.json`; camera/language keys from
-   the processor modality configs), runs the original model, and saves to one `.npz`
-   per tag: the raw observations (`raw::` keys), the exact collated inputs
-   (`in::` keys), the seed, and the raw `action_pred`.
-2. **Consumer** — the pytest above, run in the _LeRobot_ venv. It discovers every
-   `.npz`; the model-parity case replays the byte-identical collated inputs through
-   the LeRobot model with the recorded seed and asserts the outputs match, and the
-   preprocessor-parity case replays the raw observations through LeRobot's full
-   preprocessor pipeline and asserts the collated tensors match.
-
-> Artifacts generated by older versions of the dump script contain no `raw::`
-> fields; the preprocessor-parity case then **skips** with a regeneration hint.
-> Re-run the producer to refresh them.
-
-### Fairness controls
-
-- **Same pre-processed inputs (model parity)** — the original processor's `input_ids`,
-  `pixel_values`, `image_grid_thw`, `attention_mask`, `state`, `embodiment_id` are
-  fed verbatim to the LeRobot model (no re-tokenization / re-normalization), so the
-  model comparison isolates the model. LeRobot's own tokenization / image packing is
-  covered separately by the preprocessor-parity case, which compares its output
-  against those same collated tensors from identical raw observations.
-- **Same precision + attention kernel** — both sides run **fp32 + SDPA**. The
-  original defaults to `use_flash_attention=True` (flash_attention_2 + bf16); the
-  producer forces SDPA + fp32. (With the defaults the gap is ~3e-2 — pure
-  kernel/rounding noise, not an implementation difference.)
-- **Same flow-matching seed** — fixed right before sampling on both sides; the
-  producer records it in each artifact (`--seed`, default 42) and the consumer
-  replays the recorded value.
-
-### How to run
-
-```bash
-# Resolve a local checkpoint (GR00T-N1.7-LIBERO / libero_10)
-CKPT=$(python - <<'PY'
-import os
-from huggingface_hub import snapshot_download
-print(os.path.join(snapshot_download("nvidia/GR00T-N1.7-LIBERO",
-      allow_patterns=["libero_10/*"]), "libero_10"))
-PY
-)
-
-# 1) Produce the original-side artifacts for all embodiments (original gr00t venv, CUDA)
-CUDA_VISIBLE_DEVICES=0 /path/to/Isaac-GR00T/.venv-original/bin/python \
-    tests/policies/groot/utils/dump_original_n1_7.py \
-    --ckpt "$CKPT" --out-dir tests/policies/groot/artifacts --device cuda --seed 42
-
-# 2) Run the parity test (LeRobot venv) — one parametrized case per embodiment
-CUDA_VISIBLE_DEVICES=0 GROOT_PARITY_DEVICE=cuda \
-    uv run pytest tests/policies/groot/test_groot_vs_original.py -v -s
-```
-
-The `.npz` artifacts are local-only (gitignored, ~6–10 MB each) and are regenerated by
-the producer; they are never committed. The tests **skip** (do not fail) on CI or
-when the checkpoint / artifacts are absent.

 ## Dataset feature contracts
 
 Dataset features are determined by the keys saved in the dataset. Each step can declare what features it modifies in a contract called `transform_features(...)`. Once you build a processor, the processor can then aggregate all of these features with `aggregate_pipeline_dataset_features()` and merge multiple feature dicts with `combine_feature_dicts(...)`.

 Depth maps (Intel RealSense, Reachy 2) are stored as their **own video streams** alongside the RGB streams. Raw depth (`uint16` millimetres or `float32` metres) can't survive an 8-bit codec, so LeRobot **quantizes** each map to a 12-bit code (`[0, 4095]`) — logarithmically by default, to match the `1/depth` error profile of depth sensors — then packs it into a high-bit-depth pixel format (`gray12le`) and encodes it with a 12-bit codec.

-# Isaac Teleop → SO-101
-
-Teleoperate an SO-101/SO-100 follower arm — and record LeRobot datasets — with NVIDIA
-[Isaac Teleop](https://github.com/NVIDIA/IsaacTeleop). Two input devices ship today:
-
-- **XR (VR) controller** (`--teleop.type=xr_controller`) — the controller's grip pose drives the
-  end-effector through a squeeze-to-engage clutch and LeRobot's Cartesian IK pipeline; the analog
-  trigger drives the gripper.
-- **SO-101 leader arm** (`--teleop.type=so101_leader`) — a back-drivable leader arm mirrored 1:1
-  onto the follower via Isaac Teleop's native `so101_leader` plugin (no clutch, no IK).
-
-The full narrative guide (how the clutch works, CloudXR setup, headset pairing, tuning, and
-troubleshooting) is in the [LeRobot docs](https://huggingface.co/docs/lerobot/isaac_teleop)
-(source: `docs/source/isaac_teleop.mdx`). This README is the canonical install and usage
-reference.
-
-## Requirements
-
-- Linux workstation (see NVIDIA's
-  [system requirements](https://nvidia.github.io/IsaacTeleop/main/references/requirements.html)
-  for supported OS/GPU/headset combinations; `isaacteleop` publishes Linux wheels only).
-- An SO-101 (or SO-100) follower arm, calibrated with `lerobot-calibrate`.
-- For the XR device: a CloudXR-capable headset (e.g. Quest 3, Pico 4, Apple Vision Pro) on the
-  same network.
-- For the leader device: a second, back-drivable SO-101 leader arm and the `so101_leader` plugin
-  binary built from the Isaac Teleop source tree (see
-  [Build from source](https://nvidia.github.io/IsaacTeleop/main/getting_started/build_from_source/index.html)).
-
-## Installation
-
-This example lives in the LeRobot repository and is not part of the `lerobot` pip package, so
-work from a source checkout. From the repo root:
-
-```bash
-# LeRobot with the extras this example uses:
-#   feetech    - SO-101 serial motor bus
-#   kinematics - Placo IK solver (XR controller path)
-#   dataset    - dataset recording (record.py)
-# huggingface_hub >= 1.5 is needed by the automatic URDF fetch (Buckets API).
-uv pip install -e ".[feetech,kinematics,dataset]" "huggingface_hub>=1.5"
-
-# Isaac Teleop from public PyPI. `cloudxr` brings the CloudXR runtime bindings;
-# `retargeters-lite` is the scipy-based retargeter path that resolves on both
-# x86_64 and ARM (the full `retargeters` extra does not resolve on aarch64).
-uv pip install "isaacteleop[cloudxr,retargeters-lite]~=1.3.131" "scipy>=1.14"
-
-# Optional, x86_64 only: the full retargeter stack.
-uv pip install "isaacteleop[retargeters]~=1.3.131"
-```
-
-One-time CloudXR EULA (the auto-launch prompts on stdin and would hang on a headless machine):
-
-```bash
-python -m isaacteleop.cloudxr --accept-eula
-```
-
-## Usage
-
-Run everything from the repo root with `python -m` so the `examples` package resolves.
-
-### Teleoperate — XR controller
-
-```bash
-python -m examples.isaac_teleop_to_so101.teleoperate \
-    --robot.type=so101_follower \
-    --robot.port=/dev/ttyACM0 \
-    --robot.id=so101_follower_arm \
-    --teleop.type=xr_controller
-```
-
-On startup the script launches the CloudXR runtime (~30 s), prints the workstation IP to enter in
-the headset's CloudXR web client, waits for the controllers to stream, slews the arm to a reset
-pose (`--reset_to_origin=false` to skip), and then: **hold the squeeze/grip** to engage, move the
-controller to drive the arm, pull the trigger to close the gripper. Releasing the squeeze freezes
-the arm. The SO-101 URDF is fetched automatically from the `lerobot/robot-urdfs` Hugging Face
-bucket into the LeRobot cache on first run.
-
-To customize the reset pose: back-drive the arm to the pose you want, then
-
-```bash
-python -m examples.isaac_teleop_to_so101.override_reset_pose --port /dev/ttyACM0 --id so101_follower_arm
-```
-
-which writes it to `HF_LEROBOT_HOME/reset_poses/<robot.name>/<robot.id>.json`; runs with the same
-`--robot.id` use it automatically.
-
-### Teleoperate — SO-101 leader arm
-
-```bash
-python -m examples.isaac_teleop_to_so101.teleoperate \
-    --robot.type=so101_follower --robot.port=/dev/ttyACM0 --robot.id=so101_follower_arm \
-    --teleop.type=so101_leader --teleop.port=/dev/ttyACM1 --teleop.id=so101_leader_arm \
-    --launch_plugin=/path/to/IsaacTeleop/install/plugins/so101_leader/so101_leader_plugin
-```
-
-The follower is first slewed to the leader's pose over `--align_duration` seconds
-(`--align=false` to skip), then mirrors it 1:1. The plugin reuses the serial leader's calibration
-(`HF_LEROBOT_CALIBRATION/teleoperators/so_leader/<teleop.id>.json`).
-
-### Record a dataset
-
-`record.py` takes the same `--robot.*`/`--teleop.*`/loop flags plus `lerobot-record`-style
-`--dataset.*` flags:
-
-```bash
-python -m examples.isaac_teleop_to_so101.record \
-    --robot.type=so101_follower --robot.port=/dev/ttyACM0 --robot.id=so101_follower_arm \
-    --teleop.type=xr_controller \
-    --robot.cameras="{ front: {type: opencv, index_or_path: 0, width: 640, height: 480, fps: 30}}" \
-    --dataset.repo_id=<hf_user>/<dataset_name> \
-    --dataset.single_task="Pick up the cube" \
-    --dataset.num_episodes=3 --dataset.episode_time_s=20 --dataset.reset_time_s=5
-```
-
-Keyboard shortcuts (terminal-first, so they work over SSH): **Right/n** end episode early,
-**Left/r** re-record, **Esc/q** stop after the current episode.
-
-Run either script with `--help` for all flags.
-
-## Layout
-
-```
-isaac_teleop/            device library: session lifecycle (base.py), XRController,
-                         SO101LeaderArm, Clutch, configs, and the XR→IK processor step
-common.py                shared loop infra: device bundles, clutch/IK pipeline wiring,
-                         reset/align slews, URDF fetch, keyboard listener
-teleoperate.py           teleoperation CLI (device selected via --teleop.type)
-record.py                dataset-recording CLI (same device selection + --dataset.*)
-override_reset_pose.py   save the current joints as the per-arm reset pose
-default.env              CloudXR device-profile overrides passed to the launcher
-```

-Isaac Teleop is a multi-modal framework: a single ``TeleopSession`` can be driven by
-XR controllers, hand tracking, Manus gloves, etc. Each modality is a
-:class:`Teleoperator` subclass in its own ``teleop_<device>.py``.
-

-
-``isaacteleop`` is an optional NVIDIA dependency (install instructions in the example's
-``README.md``); its imports are guarded behind an availability check at module top, so this
-module imports without it and constructing a device fails fast with install instructions.

-"""SO-101 leader-arm device for NVIDIA Isaac Teleop, exposed to LeRobot.
-
-The leader is a back-drivable SO-101 whose six joint angles are streamed (in radians) by
-the native ``so101_leader`` plugin; this device reads them via a ``JointStateSource`` and
-converts them into follower-ready ``{joint}.pos``. Same kinematics as the follower, so it
-needs no retargeting — a 1:1 joint mirror, direct joint drive.
-
-Units (converted in the device so the output is always follower-valid):
-
-* arm joints: ``rad2deg`` — correct only if the leader's calibrated zero and the follower's
-  homing map to the same physical zero (the standard same-hardware assumption).
-* gripper: normalized from ``[gripper_open_rad, gripper_close_rad]`` to RANGE_0_100.
-
-``isaacteleop`` imports are guarded behind the availability flag so this module — and the
-pure :func:`leader_joints_to_robot_action` converter — import without it (construction
-fails fast via the base class).
