This dataset is a robotic task dataset created using LeRobot, focusing on dual-arm robot manipulation tasks, specifically picking vials (pickvials) in a simulated environment. It contains 263 episodes, totaling 86,556 frames at a frame rate of 10fps. Data features include observation states (observation.state) with 12 joint positions for both arms (e.g., left shoulder translation, left shoulder lift, left elbow bend, left wrist bend, left wrist roll, left gripper position, and corresponding joints on the right side); observation images (observation.images) from three cameras: left wrist camera (wrist_left), right wrist camera (wrist_right), and center camera (center), each video with a resolution of 480x640, 3 channels, encoded as av1, at 10fps; actions (action) include 12 joint position controls corresponding to the observation states; additionally, there are timestamps (timestamp), frame indices (frame_index), episode indices (episode_index), indices (index), and task indices (task_index). The dataset structure stores data in parquet files and video files for images, with a total data size of about 100MB and video size of about 200MB. The robot type is bi_so_follower, the task index is 1, and all episodes are used for training.
