The Unitree G1 humanoid is now supported in LeRobot! You can teleoperate, train locomanipulation policies, test in sim, and more. Both 29 and 23 DoF variants are supported.

<Tip>
  **New: SONIC whole-body control.** The `SonicWholeBodyController` runs NVIDIA's
  [GEAR-SONIC](https://huggingface.co/nvidia/GEAR-SONIC) decoder on the G1, turning a
  64-D latent motion token into full-body joint targets at 50 Hz. This lets you drive
  the robot from a VLA policy trained on SONIC motion tokens (token in → whole-body
  motion out) with `lerobot-rollout`, in sim or on the physical robot. See
  [Whole-body control with SONIC](#whole-body-control-with-sonic) below.

## Part 1: Getting Started

### Install the Unitree SDK

Follow the [unitree_sdk2_python installation guide](https://github.com/unitreerobotics/unitree_sdk2_python#installation). Tested with `unitree_sdk2py==1.0.1` and `cyclonedds==0.10.2`:

```bash
conda create -y -n lerobot python=3.12
conda activate lerobot
git clone https://github.com/unitreerobotics/unitree_sdk2_python.git
cd unitree_sdk2_python
pip install -e .
cd ..
```

### Install LeRobot

```bash
conda install ffmpeg -c conda-forge
conda install -c conda-forge "pinocchio>=3.0.0,<4.0.0"
git clone https://github.com/huggingface/lerobot.git
cd lerobot
pip install -e '.[unitree_g1]'
```

<Tip>
  For now, pinocchio must be installed from conda-forge (not pip) to include the
  CasADi bindings needed for arm IK.
</Tip>

### Test the Installation (Simulation)

The simulation environment has its own dependencies. Check the Simulation environment dependencies: [Unitree G1 Mujoco EnvHub](https://huggingface.co/lerobot/unitree-g1-mujoco/tree/main).

```bash
pip install mujoco loguru msgpack msgpack-numpy
```

```bash
lerobot-teleoperate \
  --robot.type=unitree_g1 \
  --robot.is_simulation=true \
  --teleop.type=unitree_g1 \
  --teleop.id=wbc_unitree \
  --robot.cameras='{"global_view": {"type": "zmq", "server_address": "localhost", "port": 5555, "camera_name": "head_camera", "width": 640, "height": 480, "fps": 30, "warmup_s": 5}}' \
  --display_data=true \
  --robot.controller=GrootLocomotionController
```

This will launch a [MuJoCo sim instance](https://huggingface.co/lerobot/unitree-g1-mujoco/tree/main) for the G1. You can connect a gamepad to your machine before launching in order to control the robot's locomotion in sim. We support [HolosomaLocomotionController](https://github.com/amazon-far/holosoma), [GrootLocomotionController](https://github.com/NVlabs/GR00T-WholeBodyControl), and [SonicWholeBodyController](https://huggingface.co/nvidia/GEAR-SONIC) via `--robot.controller`.

- Press `7` / `8` to increase / decrease waist height

### Connect to the Physical Robot

The G1's Ethernet IP is fixed at `192.168.123.164`. Your machine must have a static IP on the same subnet: `192.168.123.x` where `x ≠ 164`.

```bash
# Replace 'enp131s0' with your ethernet interface name (check with `ip a`)
sudo ip addr flush dev enp131s0
sudo ip addr add 192.168.123.200/24 dev enp131s0
sudo ip link set enp131s0 up
```

### SSH into the Robot

```bash
ssh unitree@192.168.123.164
# Password: 123
```

### Share Internet via Ethernet

The G1 needs internet access to clone repos and install packages. Share your laptop's connection over Ethernet:

**On your laptop:**

```bash
sudo sysctl -w net.ipv4.ip_forward=1

# Replace wlp132s0f0 with your WiFi interface name
sudo iptables -t nat -A POSTROUTING -o wlp132s0f0 -s 192.168.123.0/24 -j MASQUERADE
sudo iptables -A FORWARD -i wlp132s0f0 -o enp131s0 -m state --state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i enp131s0 -o wlp132s0f0 -j ACCEPT
```

**On the G1:**

```bash
sudo ip route del default 2>/dev/null || true
sudo ip route add default via 192.168.123.200 dev eth0
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf

# Verify
ping -c 3 8.8.8.8
```

### Install the Unitree SDK on the G1

Follow the [unitree_sdk2_python installation guide](https://github.com/unitreerobotics/unitree_sdk2_python#installation):

```bash
conda create -y -n lerobot python=3.12
conda activate lerobot
git clone https://github.com/unitreerobotics/unitree_sdk2_python.git
cd unitree_sdk2_python
python -m pip install -e .
cd ..
```

### Install LeRobot on the G1

```bash
git clone https://github.com/huggingface/lerobot.git
cd lerobot
conda install -c conda-forge "pinocchio>=3.0.0,<4.0.0"
python -m pip install -e '.[unitree_g1]'
```

<Tip>
  For now, pinocchio must be installed from conda-forge (not pip) to include the
  CasADi bindings needed for arm IK.
</Tip>

### (Optional) Enable WiFi on the Robot

For wireless SSH access, you can enable WiFi on the G1 (it's blocked by default):

```bash
sudo rfkill unblock all
sudo ip link set wlan0 up
sudo nmcli radio wifi on
sudo nmcli device set wlan0 managed yes
sudo systemctl restart NetworkManager
```

**Connect to a WiFi network:**

```bash
nmcli device wifi list

sudo nmcli connection add type wifi ifname wlan0 con-name "YourNetwork" ssid "YourNetwork"
sudo nmcli connection modify "YourNetwork" wifi-sec.key-mgmt wpa-psk
sudo nmcli connection modify "YourNetwork" wifi-sec.psk "YourPassword"
sudo nmcli connection modify "YourNetwork" connection.autoconnect yes
sudo nmcli connection up "YourNetwork"

ip a show wlan0
```

You can then SSH over WiFi instead of Ethernet:

```bash
ssh unitree@<ROBOT_WIFI_IP>
# Password: 123
```

---

## Part 2: Teleoperation & Locomotion

### Run the Robot Server

On the robot (from `~/lerobot`):

```bash
cd ~/lerobot
python src/lerobot/robots/unitree_g1/run_g1_server.py --camera
```

### Run the Locomotion Policy

You can run the teleoperation client from your laptop over Ethernet, over WiFi (experimental), or directly on the robot itself. Mind potential latency introduced by your network.

**From your laptop:**

```bash
lerobot-teleoperate \
  --robot.type=unitree_g1 \
  --robot.is_simulation=false \
  --robot.robot_ip=<ROBOT_IP> \
  --teleop.type=unitree_g1 \
  --teleop.id=wbc_unitree \
  --robot.cameras='{"global_view": {"type": "zmq", "server_address": "<ROBOT_IP>", "port": 5555, "camera_name": "head_camera", "width": 640, "height": 480, "fps": 30}}' \
  --display_data=true \
  --robot.controller=HolosomaLocomotionController
```

We support both [GrootLocomotionController](https://github.com/NVlabs/GR00T-WholeBodyControl) and [HolosomaLocomotionController](https://github.com/amazon-far/holosoma) via `--robot.controller`.

## Part 3: Loco-Manipulation with the Homunculus Exoskeleton

We provide a loco-manipulation solution via the Homunculus Exoskeleton — an open-source 7 DoF exoskeleton for whole-body control. Check it out [here](https://github.com/nepyope/hmc_exo).

### Calibrate

```bash
lerobot-calibrate \
  --teleop.type=unitree_g1 \
  --teleop.left_arm_config.port=/dev/ttyACM1 \
  --teleop.right_arm_config.port=/dev/ttyACM0 \
  --teleop.id=exo
```

During calibration move each joint through its entire range. After fitting, move the joint in a neutral position and press `n` to advance.

### Record a Dataset

```bash
lerobot-record \
  --robot.type=unitree_g1 \
  --robot.is_simulation=true \
  --robot.cameras='{"global_view": {"type": "zmq", "server_address": "localhost", "port": 5555, "camera_name": "head_camera", "width": 640, "height": 480, "fps": 30}}' \
  --teleop.type=unitree_g1 \
  --teleop.left_arm_config.port=/dev/ttyACM1 \
  --teleop.right_arm_config.port=/dev/ttyACM0 \
  --teleop.id=exo \
  --dataset.repo_id=your-username/dataset-name \
  --dataset.single_task="Test" \
  --dataset.num_episodes=2 \
  --dataset.episode_time_s=5 \
  --dataset.reset_time_s=5 \
  --dataset.push_to_hub=true \
  --dataset.streaming_encoding=true \
  --dataset.encoder_threads=2
```

> **Note:** Omit `--teleop.left_arm_config.port` and `--teleop.right_arm_config.port` if you're only using the joystick.

Example dataset: [nepyope/unitree_box_move_blue_full](https://huggingface.co/datasets/nepyope/unitree_box_move_blue_full)

## Part 4: Training & Inference

### Train

```bash
python src/lerobot/scripts/lerobot_train.py \
  --dataset.repo_id=your-username/dataset-name  \
  --policy.type=pi05 \
  --output_dir=./outputs/pi05_training \
  --job_name=pi05_training \
  --policy.repo_id=your-username/your-repo-id \
  --policy.pretrained_path=lerobot/pi05_base \
  --policy.compile_model=true \
  --policy.gradient_checkpointing=true \
  --wandb.enable=true \
  --policy.dtype=bfloat16 \
  --policy.freeze_vision_encoder=false \
  --policy.train_expert_only=false \
  --steps=3000 \
  --policy.device=cuda \
  --batch_size=32
```

### Inference with RTC

Once trained, we recommend deploying policies using inference-time RTC:

```bash
lerobot-rollout \
  --strategy.type=base \
  --policy.path=your-username/your-repo-id \
  --policy.device=cuda \
  --robot.type=unitree_g1 \
  --robot.is_simulation=false \
  --robot.controller=HolosomaLocomotionController \
  --robot.cameras='{"global_view": {"type": "zmq", "server_address": "<ROBOT_IP>", "port": 5555, "camera_name": "head_camera", "width": 640, "height": 480, "fps": 30}}' \
  --task="task_description" \
  --duration=1000 \
  --fps=30 \
  --inference.type=rtc
```

## Whole-body control with SONIC

The `SonicWholeBodyController` runs NVIDIA's [GEAR-SONIC](https://huggingface.co/nvidia/GEAR-SONIC)
decoder on the G1. Each 50 Hz tick it consumes a **64-D latent motion token** and emits
full-body joint targets — the encoder is bypassed, so a policy feeds tokens in and the
decoder turns them into motion. Before the first token arrives the controller holds a
neutral (idle) pose.

This makes the G1 drivable by a VLA policy trained to output SONIC motion tokens (token
as both `observation.state` and `action`, e.g. [`nepyope/sonic_walk`](https://huggingface.co/nepyope/sonic_walk))
using the standard `lerobot-rollout`. The controller always runs **onboard** the robot;
the laptop is a thin client that streams tokens and receives camera frames over ZMQ.

**On the robot** — start the server in handshake mode so it instantiates and runs the
controller onboard against local DDS at full rate:

```bash
cd ~/lerobot
python src/lerobot/robots/unitree_g1/run_g1_server.py --handshake --camera
```

**From your laptop** — run the token policy; `--robot.sonic_token_action=true` switches the
robot to the 64-D latent-token action/observation interface:

```bash
lerobot-rollout \
  --policy.path=nepyope/sonic_walk \
  --policy.device=cuda \
  --robot.type=unitree_g1 \
  --robot.is_simulation=false \
  --robot.robot_ip=<ROBOT_IP> \
  --robot.controller=SonicWholeBodyController \
  --robot.sonic_token_action=true \
  --robot.cameras='{"ego_view": {"type": "zmq", "server_address": "<ROBOT_IP>", "port": 5555, "camera_name": "head_camera", "width": 640, "height": 480, "fps": 30}}' \
  --task="walk back and forth" \
  --duration=1000 \
  --fps=30
```

<Tip>
  SONIC is a token-only decoder in LeRobot: the only input path is the 64-D latent
  vector. To train your own token policy, expose the 64-D token as the action (a config
  choice, e.g. `pi05` with a 64-D action dim) — no policy code changes are needed.
</Tip>
