This dataset is created by the LeRobot project and is designed for robotics research, containing simulation or real robot interaction data. The dataset includes 330 episodes, 130,962 frames, and 90 tasks, with a total data file size of approximately 100 MB and a video file size of about 200 MB, at a frame rate of 30 FPS. Data is stored in Parquet file format, videos are in MP4 format, and it only includes a training set. Features include: action (a 5-dimensional floating-point vector representing end-effector velocities in x, y, z directions, wrist speed, and finger speed), state observation (a 43-dimensional floating-point vector covering gripper position, rotation, finger angles, laser ranging, pressure sensors, target orientation/distance, and other robot body and environmental states), image observation (RGB video captured by a gripper camera, with a resolution of 384x384, 3 channels, 30 FPS, no audio), as well as timestamps, frame indices, episode indices, global indices, and task indices. It is suitable for tasks such as robot imitation learning, reinforcement learning, state estimation, and visual servoing.
