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
Gazebo
Gazebo simulates robots with their sensors and environment — the classic testing ground before deploying to real hardware.
- Realistic sensor simulation
- Tight ROS integration
- Decades of robotics use behind it
