Application

Imitation learning and Reinforcement learning

The LeRobot framework is compatible with the SO-ARM100 robotic arm. It provides complete data collection, training, and deployment for teaching the robotic arm, and also has a comprehensive simulation platform. On the Nvidia Jetson edge device, it's easy and quick to train a customized robotic arm to complete grasping and placing tasks.
