π₀ (Pi0) is a general-purpose robot foundation model from Physical Intelligence: a generalist Vision-Language-Action policy that understands visual inputs, interprets natural language instructions, and controls a variety of different robots across diverse tasks. The LeRobot implementation is adapted from their open-source OpenPI repository.
This policy has been trained and pushed to the Hub using
LeRobot.
Learn how to train and run it in the
LeRobot pi0 guide, or browse the
full documentation.
The policy consumes these observation features and produces these action features.
1lerobot-rollout \
2 --strategy.type=base \
3 --robot.type=so_follower \
4 --robot.port=<your_robot_port> \
5 --robot.cameras="{ <camera_1>: {type: opencv, index_or_path: <index_or_path>, width: 640, height: 480, fps: 30}, <camera_2>: {type: opencv, index_or_path: <index_or_path>, width: 640, height: 480, fps: 30}}" \
6 --policy.path=Mark-Teeratorn/pi0_snack_policy \
7 --task="Put the snack in the hand" \
8 --duration=60
When
--strategy.type=base is used the script doesn't record the episodes. Skipping duration will make the policy run indefinitely. For more information look at
rollout documentation.
This policy type is usually fine-tuned from the pretrained base model
lerobot/pi0_base:
1lerobot-train \
2 --dataset.repo_id=${HF_USER}/<dataset> \
3 --policy.path=lerobot/pi0_base \
4 --output_dir=outputs/train/<policy_repo_id> \
5 --job_name=lerobot_training \
6 --policy.device=cuda \
7 --policy.repo_id=${HF_USER}/<policy_repo_id> \
8 --wandb.enable=true
