This dataset was created by LeRobot for robot learning tasks. It contains 35 episodes, totaling 94,946 frames, collected using the ALOHA robot platform. Data features include: 14-dimensional robot states (such as joint positions of the left and right robotic arms), 14-dimensional action commands, 14-dimensional velocity and force information, and video data from four cameras (cam_high, cam_low, cam_left_wrist, cam_right_wrist), each with a resolution of 480x640, a frame rate of 50fps, and AV1 encoding. The dataset also includes metadata such as task indices, subtask labels, training flags, timestamps, frame indices, and episode indices. Data is stored in parquet format, with a total data volume of approximately 200MB, video file size of about 200MB, and all data is used for training.
