What each one is
LeRobot
LeRobot brings pretrained models, datasets and simulation environments for real-world robotics into one Python library — the closest thing the field has to a Transformers moment.
- Pretrained policies and shared datasets on the Hub
- Works with cheap off-the-shelf arms, not just lab hardware
- Backed by an active community and weekly releases
openpi (π0)
openpi releases the π0 family of vision-language-action models — robot policies pretrained on large multi-robot datasets, ready to fine-tune.
- Genuinely open weights for robot foundation models
- Fine-tunes on modest hardware
- From one of the leading robotics labs
