This dataset is created by LeRobot and focuses on the field of robotics. It contains multimodal data from robots performing tasks, including: 16-dimensional action vectors (such as left and right joint positions and velocities) and state observation vectors; as well as image observations from three cameras (cam_high, cam_left_wrist, cam_right_wrist), with each video frame at a resolution of 480x640 RGB. Additionally, the dataset provides metadata such as timestamps, frame indices, episode indices, and task indices. The data is stored in Parquet file format, and videos are stored in MP4 format, making it suitable for research in robot learning and control algorithm development.
