This dataset is a robot control dataset created using LeRobot, specifically designed for robot learning and control tasks. It contains observation and action data from a Sawyer robot, with a total of 4278 episodes and 637138 frames, covering 74 different tasks. The data is collected at a rate of 20 frames per second and includes various observation features: state observations (8-dimensional floating-point numbers, including position, axis-angle, and gripper state), end-effector state (6-dimensional floating-point numbers), joint state (7-dimensional floating-point numbers), gripper state (2-dimensional floating-point numbers), and two 256x256 RGB image observations (from the main camera and wrist camera). The action data consists of 7-dimensional floating-point numbers that control the robots position, axis-angle, and gripper. The dataset also contains metadata such as timestamps, frame indices, episode indices, indices, and task indices. The data is stored in Parquet format, and videos are stored in MP4 format, with the total data size approximately 100MB and video size approximately 200MB.
