This is a robotics dataset created using the LeRobot tool, specifically designed for robot learning and control tasks. The dataset consists of 13 episodes, totaling 8670 frames, stored in parquet format with accompanying video files. Data features include: action data (6 joint positions), observation states (6 joint positions), multi-view images (from wrist, middle, top, right, and left cameras, with a resolution of 480x640, 30fps, H.264 encoding), motor current and speed (6 joints), sensor timestamps (8 time points), depth maps (middle camera, 480x640 resolution), and metadata such as timestamps, frame indices, and episode indices. The robot type is so_follower, and the dataset structure supports training splits (all 13 episodes).
