This dataset is a robotics dataset created using LeRobot, focusing on robotic arm control. It contains 50 episodes, totaling 13745 frames, with a sampling rate of 30fps. Features include actions (10-dimensional float arrays representing joint positions and velocities), observation states (10-dimensional float arrays representing joint and wheel positions), multi-view image observations (front, side, and top view videos with a resolution of 480x640, RGB three channels, H.264 encoding), as well as metadata such as timestamps, frame indices, and episode indices. Data is stored in Parquet format, videos are stored in MP4 format, with a total data file size of 100MB and video file size of 200MB. The robot type is so_follower, suitable for training and evaluating robot control models.
