LeRobot

LeRobot is an open-source framework from Hugging Face aiming to become the Hugging Face of robotics. Provides state-of-the-art policies (diffusion, ACT), standardized LeRobotDataset format, and hardware-agnostic training. In July 2026, LeRobot added full language support to its dataset format via lerobot-annotate, a VLM-based tool that automatically generates rich annotations per episode including subtasks, plans, memory/context, and grounded Q&A at ~$1.20 per 100 episodes. Enables training models for planning, memory, tool use, or low-level control from the same dataset.
