feat(envs): add RoboCasa365 benchmark integration (#3375)

* feat(envs): add RoboCasa365 benchmark integration

Add RoboCasa365 (arXiv:2603.04356) as a new simulation benchmark with
365 everyday kitchen manipulation tasks across 2,500 diverse environments.

New files:
- src/lerobot/envs/robocasa.py: gym.Env wrapper with deferred env creation,
  flat 12D action / 16D state vectors, 3-camera support
- docs/source/robocasa.mdx: user-facing documentation
- docker/Dockerfile.benchmark.robocasa: CI benchmark image

Modified files:
- src/lerobot/envs/configs.py: RoboCasaEnv config (--env.type=robocasa)
- pyproject.toml: robocasa optional dependency group
- docs/source/_toctree.yml: sidebar entry
- .github/workflows/benchmark_tests.yml: integration test job

* fix(docker): use uv pip to install robocasa in benchmark image

The huggingface/lerobot-gpu base image uses `uv` with a venv at
/lerobot/.venv — `pip` is not on PATH, so `pip install` fails with
"pip: not found". Switch to `uv pip install` which installs into the
existing venv.

Also drop the @v1.0.0 tag pin from the robocasa git URL since the
upstream repo may not have that tag; use default branch instead.

* fix(robocasa): editable install + switch to lerobot/smolvla_robocasa

- pip install from git omits data files like box_links_assets.json
  (not declared in package_data). Clone and install editable so the
  source tree is used at runtime.
- Download only tex + fixtures_lw asset types (smoke test doesn't need
  objaverse/aigen objects). Pipe 'y' to auto-accept download prompt.
- Switch CI policy from pepijn223/smolvla_robocasa to lerobot/smolvla_robocasa.

* fix(docker): re-install lerobot editably after COPY

The nightly huggingface/lerobot-gpu image predates the RoboCasaEnv
registration — so `lerobot-eval --env.type=robocasa` fails at argparse
with "invalid choice" even after COPY . . overlays the new source.
Force an editable reinstall so the venv picks up the current configs.py.


* fix(ci): add rename_map for robocasa eval (image* -> camera*)

Policy lerobot/smolvla_robocasa expects observation.images.camera1/2/3,
but RoboCasaEnv produces observation.images.image/image2/image3.

* fix(robocasa): override RoboCasaGymEnv default split (test -> all)

RoboCasaGymEnv defaults split="test", but create_env only accepts
{None, "all", "pretrain", "target"}, so the out-of-the-box default
crashes with ValueError. Always pass "all" when split is None.


* fix(docker): also download objs_lw (lightwheel objects) for robocasa

Kitchen tasks (e.g. CloseFridge) reference lightwheel object meshes
like Stool022/model.xml. fixtures_lw alone isn't enough — we also
need objs_lw. Still skipping objaverse/aigen to keep image size down.

Made-with: Cursor

* feat(robocasa): raw camera names + benchmark-group task shortcuts

Align the LeRobot env with RoboCasa's native conventions so policies
trained on the upstream datasets don't need a --rename_map at eval
time, and expose the standard task groups as first-class --env.task
values.

- Preserve raw RoboCasa camera names (e.g. robot0_agentview_left)
  as observation.images.<name> end-to-end. Drops camera_name_mapping
  and DEFAULT_CAMERA_NAME_MAPPING; features/features_map are now
  built dynamically from the parsed camera list.
- Accept benchmark-group names as --env.task: atomic_seen,
  composite_seen, composite_unseen, pretrain50/100/200/300. Expanded
  lazily via robocasa.utils.dataset_registry and auto-sets the
  split ("target" | "pretrain").
- Update CI smoke-eval rename_map to map raw cam names to the
  camera1/2/3 keys expected by lerobot/smolvla_robocasa.


* docs(robocasa): single-task smolvla train+eval recipe on pepijn223/robocasa_CloseFridge

- Rewrite observation section to use raw RoboCasa camera keys
  (observation.images.robot0_agentview_{left,right},
  observation.images.robot0_eye_in_hand).
- Add a "Training on a single task" section with a full smolvla
  training command on pepijn223/robocasa_CloseFridge, plus matching
  single-task eval command.
- Document benchmark-group task shortcuts (atomic_seen, composite_seen,
  composite_unseen, pretrain50/100/200/300) as valid --env.task values.


* fix(robocasa): restrict obj_registries to lightwheel by default

CloseFridge (and most kitchen tasks) crashed at reset with
`ValueError: Probabilities contain NaN` coming out of
`sample_kitchen_object_helper`. RoboCasa's upstream default
`obj_registries=("objaverse", "lightwheel")` normalizes per-registry
candidate counts as probabilities; when a sampled category has zero
mjcf paths in every configured registry (because the objaverse asset
pack isn't on disk — ~30GB, skipped by our Docker build), the 0/0
divide yields NaNs and `rng.choice` raises.

- Add `obj_registries: list[str] = ["lightwheel"]` to `RoboCasaEnv`
  config; thread it through `create_robocasa_envs`, `_make_env_fns`,
  and the gym.Env wrapper to the underlying `RoboCasaGymEnv` (which
  forwards to `create_env` → `robosuite.make` → kitchen env).
- Default matches what `download_kitchen_assets --type objs_lw`
  actually ships, so the env works out of the box without a 30GB
  objaverse download.
- Document the override (`--env.obj_registries='[objaverse,lightwheel]'`)
  for users who have downloaded the full asset set.


* fix(docker): also download tex_generative for robocasa benchmark

RoboCasa's lightwheel kitchen fixtures embed references to
`generative_textures/wall/tex*.png` directly in their MuJoCo XML, so
`MjModel.from_xml_string` errors out at reset time with
"No such file or directory" even when the env is constructed with
`generative_textures=None`. The generative textures live under a
separate asset registry key (`tex_generative`) in
`download_kitchen_assets`, distinct from the base `tex` pack we were
already fetching.

- Add `tex_generative` to the download list so the fixture XMLs
  resolve.
- Document the remaining omissions (objaverse/aigen, ~30GB) and how
  the runtime side pairs this with obj_registries=["lightwheel"] to
  avoid sampling from categories whose assets aren't on disk.

* ci(robocasa): smoke-eval 10 atomic tasks instead of 1

Broader coverage in the benchmark CI job: evaluate SmolVLA on ten
fixture-centric atomic RoboCasa tasks (one episode each) instead of
just CloseFridge. The tasks are all drawn from TARGET_TASKS.atomic_seen
and selected to avoid object-manipulation categories that would require
the objaverse/aigen asset packs (we only ship objs_lw in the Docker
image, paired with obj_registries=["lightwheel"] on the runtime side).

Tasks: CloseFridge, OpenCabinet, OpenDrawer, TurnOnMicrowave,
TurnOffStove, CloseToasterOvenDoor, SlideDishwasherRack,
TurnOnSinkFaucet, NavigateKitchen, TurnOnElectricKettle.

`scripts/ci/parse_eval_metrics.py` already handles multi-task output
via the `overall` key, so no parser changes needed. Bumped the metrics
artifact's task label to `atomic_smoke_10` to reflect the grouping.

* fix(pyproject): drop unresolvable robocasa extra

robocasa's upstream setup.py hardcodes `lerobot==0.3.3` in
install_requires. Exposing it as the `lerobot[robocasa]` extra made
uv's dep resolver cycle: `lerobot[robocasa]` -> robocasa -> lerobot
(a different version) -> unsolvable. This broke every `uv sync` — even
invocations with an unrelated extra like `--extra test` — because uv
validates the whole lockfile graph.

- Remove the `robocasa` extra from pyproject.toml. Installation
  instructions in docs/source/robocasa.mdx now walk users through the
  manual `git clone` + `pip install --no-deps` flow, which matches
  what the Docker image already does and sidesteps the cyclic dep
  entirely.
- Dockerfile: `uv pip install -e ~/robocasa --no-deps` so the
  shadowed lerobot==0.3.3 never lands in the image; install
  robocasa's actual runtime deps (numpy, numba, scipy, mujoco,
  tianshou, etc.) explicitly.

* docs(robocasa): align page with adding_benchmarks template

Rework docs/source/robocasa.mdx to follow the standard benchmark doc
structure: intro + links + available tasks (with family breakdown and
first-class benchmark-group shortcuts) + installation + eval +
recommended episodes + policy I/O + training + reproducing results.

- Fix the paper link (was pointing at a non-existent arxiv ID).
- Surface lerobot/smolvla_robocasa and pepijn223/robocasa_CloseFridge
  in the top-of-page links so they're findable without reading the
  training section.
- Add an explicit "Object registries" subsection explaining the
  `--env.obj_registries=[objaverse,lightwheel]` override path.
- Add an explicit "Reproducing published results" section pointing
  at the CI smoke eval.

* fix: integrate PR #3375 review feedback

- envs(robocasa): hoist the duplicated `_parse_camera_names` helper
  out of `libero.py` and `robocasa.py` into `envs/utils.py` as the
  public `parse_camera_names`; call sites updated.
- envs(robocasa): give each factory a distinct `episode_index`
  (`0..n_envs-1`) and derive a per-worker seed series in `reset()`
  so n_envs workers don't all roll the same scene under a shared
  outer seed.
- envs(robocasa): drop the unused `**kwargs` on `_make_env`; declare
  `visualization_height` / `visualization_width` on both the wrapper
  and the `RoboCasaEnv` config + propagate via `gym_kwargs`.
- envs(robocasa): emit `info["final_info"]` on termination (matching
  MetaWorld) so downstream vector-env auto-reset keeps the terminal
  task/success flags.
- docs(robocasa): add `--rename_map` (robot0_agentview_left/
  eye_in_hand/agentview_right → camera1/2/3) plus CI-parity flags to
  all three eval snippets.
- docker(robocasa): pin robocasa + robosuite git SHAs and the pip
  dep versions (pygame, Pillow, opencv-python, pyyaml, pynput, tqdm,
  termcolor, imageio, h5py, lxml, hidapi, gymnasium) for
  reproducible benchmark images.
- ci(robocasa): update the workflow comment — there is no
  `lerobot[robocasa]` extra; robocasa/robosuite are installed
  manually because upstream's `lerobot==0.3.3` pin shadows ours.

* docs(robocasa): add benchmark banner image

* fix(envs): preserve AsyncVectorEnv metadata/unwrapped in lazy eval envs

Port of #3416 onto this branch. Also threads the cached metadata
through the RoboCasa factory so async eval on `--env.type=robocasa`
keeps the same improvement.


* fix: integrate PR #3375 review feedback (round 2)

- envs(robocasa): when the caller passes `seed=None` to `reset()`,
  fall back to `self.episode_index` for the inner env seed so each
  worker still samples a distinct trajectory instead of all workers
  inheriting the same global RNG state.
- envs(robocasa): replace the two module-level `print()` calls in
  `create_robocasa_envs` with `logger.info(...)` via a module-level
  `logger = logging.getLogger(__name__)`.
- ci(robocasa): run `scripts/ci/extract_task_descriptions.py` after
  the eval so `metrics.json` carries per-task natural-language
  labels, matching LIBERO / MetaWorld / VLABench jobs. Added a
  `_robocasa_descriptions()` extractor that splits CamelCase task
  names into word-level labels keyed by `<task>_0`.

# RoboCasa365
[RoboCasa365](https://robocasa.ai) is a large-scale simulation framework for training and benchmarking **generalist robots** in everyday kitchen tasks. It ships 365 diverse manipulation tasks across 2,500 kitchen environments, 3,200+ object assets and 600+ hours of human demonstration data, on a PandaOmron 12-DOF mobile manipulator (Franka arm on a holonomic base).

width="85%"
/>
## Available tasks
RoboCasa365 organizes its 365 tasks into two families and three upstream benchmark groups that LeRobot exposes as first-class `--env.task` shortcuts:
| Family | Tasks | Description |
| --------- | ----- | ------------------------------------------------------------------------------- |
| Atomic | ~65 | Single-skill tasks: pick-and-place, door/drawer manipulation, appliance control |
| Composite | ~300 | Multi-step tasks across 60+ categories: cooking, cleaning, organizing, etc. |
**Atomic task examples:** `CloseFridge`, `OpenDrawer`, `OpenCabinet`, `TurnOnMicrowave`, `TurnOffStove`, `NavigateKitchen`, `PickPlaceCounterToStove`.
**Composite task categories:** baking, boiling, brewing, chopping, clearing table, defrosting food, loading dishwasher, making tea, microwaving food, washing dishes, and more.
`--env.task` accepts three forms:
- a single task name (`CloseFridge`)
- a comma-separated list (`CloseFridge,OpenBlenderLid,PickPlaceCoffee`)
- a benchmark-group shortcut — `atomic_seen`, `composite_seen`, `composite_unseen`, `pretrain50`, `pretrain100`, `pretrain200`, `pretrain300` — which auto-expands to the upstream task list and auto-sets the dataset `split` (`target` or `pretrain`).
## Installation
RoboCasa and its dependency `robosuite` are not published on PyPI, and RoboCasa's own `setup.py` hardcodes `lerobot==0.3.3`, which conflicts with this repo's `lerobot`. LeRobot therefore does **not** expose a `robocasa` extra — install the two packages manually as editable clones (using `--no-deps` on `robocasa` to skip its shadowed `lerobot` pin):
```bash
# After following the standard LeRobot installation instructions.
git clone https://github.com/robocasa/robocasa.git ~/robocasa
git clone https://github.com/ARISE-Initiative/robosuite.git ~/robosuite
pip install -e ~/robocasa --no-deps
pip install -e ~/robosuite
# Robocasa's runtime deps (the ones its setup.py would have pulled, minus
# the bad lerobot pin).
pip install numpy numba scipy mujoco pygame Pillow opencv-python \
pyyaml pynput tqdm termcolor imageio h5py lxml hidapi \
tianshou gymnasium
python -m robocasa.scripts.setup_macros
# Lightweight assets (lightwheel object meshes + textures). Enough for
# the default env out of the box.
python -m robocasa.scripts.download_kitchen_assets \
--type tex tex_generative fixtures_lw objs_lw
# Optional: full objaverse/aigen registries (~30GB) for richer object
# variety. Enable at eval time via --env.obj_registries (see below).
# python -m robocasa.scripts.download_kitchen_assets --type objs_objaverse
```
<Tip>
RoboCasa requires MuJoCo. Set the rendering backend before training or evaluation:
```bash
export MUJOCO_GL=egl # for headless servers (HPC, cloud)
```
</Tip>
### Object registries
By default the env samples objects only from the `lightwheel` registry (what `--type objs_lw` ships), which avoids a `Probabilities contain NaN` crash when the objaverse / aigen packs aren't on disk. If you've downloaded the full asset set, enable the full registry at runtime:
```bash
--env.obj_registries='[objaverse,lightwheel]'
```
## Evaluation
All eval snippets below mirror the CI command (see `.github/workflows/benchmark_tests.yml`). The `--rename_map` argument maps RoboCasa's native camera keys (`robot0_agentview_left` / `robot0_eye_in_hand` / `robot0_agentview_right`) onto the three-camera (`camera1` / `camera2` / `camera3`) input layout the released `smolvla_robocasa` policy was trained on.
### Single-task evaluation (recommended for quick iteration)
```bash
lerobot-eval \
--policy.path=lerobot/smolvla_robocasa \
--env.type=robocasa \
--env.task=CloseFridge \
--eval.batch_size=1 \
--eval.n_episodes=20 \
--eval.use_async_envs=false \
--policy.device=cuda \
'--rename_map={"observation.images.robot0_agentview_left": "observation.images.camera1", "observation.images.robot0_eye_in_hand": "observation.images.camera2", "observation.images.robot0_agentview_right": "observation.images.camera3"}'
```
### Multi-task evaluation
Pass a comma-separated list of tasks:
```bash
lerobot-eval \
--policy.path=lerobot/smolvla_robocasa \
--env.type=robocasa \
--env.task=CloseFridge,OpenCabinet,OpenDrawer,TurnOnMicrowave,TurnOffStove \
--eval.batch_size=1 \
--eval.n_episodes=20 \
--eval.use_async_envs=false \
--policy.device=cuda \
'--rename_map={"observation.images.robot0_agentview_left": "observation.images.camera1", "observation.images.robot0_eye_in_hand": "observation.images.camera2", "observation.images.robot0_agentview_right": "observation.images.camera3"}'
```
### Benchmark-group evaluation
Run an entire upstream group (e.g. all 18 `atomic_seen` tasks with `split=target`):
```bash
lerobot-eval \
--policy.path=lerobot/smolvla_robocasa \
--env.type=robocasa \
--env.task=atomic_seen \
--eval.batch_size=1 \
--eval.n_episodes=20 \
--eval.use_async_envs=false \
--policy.device=cuda \
'--rename_map={"observation.images.robot0_agentview_left": "observation.images.camera1", "observation.images.robot0_eye_in_hand": "observation.images.camera2", "observation.images.robot0_agentview_right": "observation.images.camera3"}'
```
### Recommended evaluation episodes
**20 episodes per task** for reproducible benchmarking. Matches the protocol used in published results.
## Policy inputs and outputs
**Observations** (raw RoboCasa camera names are preserved verbatim):
- `observation.state` — 16-dim proprioceptive state (base position, base quaternion, relative end-effector position, relative end-effector quaternion, gripper qpos)
- `observation.images.robot0_agentview_left` — left agent view, 256×256 HWC uint8
- `observation.images.robot0_eye_in_hand` — wrist camera view, 256×256 HWC uint8
- `observation.images.robot0_agentview_right` — right agent view, 256×256 HWC uint8
**Actions:**
- Continuous control in `Box(-1, 1, shape=(12,))` — base motion (4D) + control mode (1D) + end-effector position (3D) + end-effector rotation (3D) + gripper (1D).
## Training
### Single-task example
A ready-to-use single-task dataset is on the Hub:
[`pepijn223/robocasa_CloseFridge`](https://huggingface.co/datasets/pepijn223/robocasa_CloseFridge).
Fine-tune a SmolVLA base on `CloseFridge`:
```bash
lerobot-train \
--policy.type=smolvla \
--policy.repo_id=${HF_USER}/smolvla_robocasa_CloseFridge \
--policy.load_vlm_weights=true \
--policy.push_to_hub=true \
--dataset.repo_id=pepijn223/robocasa_CloseFridge \
--env.type=robocasa \
--env.task=CloseFridge \
--output_dir=./outputs/smolvla_robocasa_CloseFridge \
--steps=100000 \
--batch_size=4 \
--eval_freq=5000 \
--eval.batch_size=1 \
--eval.n_episodes=5 \
--save_freq=10000
```
Evaluate the resulting checkpoint:
```bash
lerobot-eval \
--policy.path=${HF_USER}/smolvla_robocasa_CloseFridge \
--env.type=robocasa \
--env.task=CloseFridge \
--eval.batch_size=1 \
--eval.n_episodes=20
```
## Reproducing published results
The released checkpoint [`lerobot/smolvla_robocasa`](https://huggingface.co/lerobot/smolvla_robocasa) is evaluated with the commands in the [Evaluation](#evaluation) section. CI runs a 10-atomic-task smoke eval (one episode each) on every PR touching the benchmark, picking fixture-centric tasks that don't require the objaverse asset pack.
