This dataset is a robotics dataset created by LeRobot for robot tasks. It contains 5 episodes, totaling 924 frames, collected at a rate of 30 frames per second. Features include 6-dimensional floating-point actions and observation states (corresponding to shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position), as well as image observations from three perspectives: side, wrist, and front, each with a resolution of 480x640 pixels, 3 channels, encoded in AV1. Additionally, the dataset includes metadata such as timestamps, frame index, episode index, index, and task index. The robot type is so_follower, with a total data file size of 100MB and a total video file size of 200MB, suitable for training and robot control tasks.
