LeRobot HF Dataset

The LeRobot dataset format is a standardized schema for robot demonstration data hosted on the Hugging Face Hub. Each dataset consists of Parquet files (for scalar timeseries: joint positions, actions, rewards, done flags) plus compressed MP4 video chunks for camera streams, all indexed by episode and frame. A meta/info.json file describes camera names, robot type, fps, and data statistics used for normalization. This format allows any LeRobot-compatible algorithm to load any published dataset with a single line of code, enabling rapid cross-dataset experimentation. Dozens of manipulation and mobile manipulation datasets are already published in this format.
