This dataset is a robotic manipulation dataset developed using the LeRobot platform, focusing on the Grabette robot type. It contains 3 complete episodes and 979 frames of data, involving one single task. The data is stored in the form of video and action data, including RGB video streams from two cameras (cam0 and cam1) with a resolution of 720×960 and a frame rate of 50 fps, as well as an 8-dimensional action vector. The vector includes position coordinates (x, y, z), rotational parameters (ax, ay, az), and proximal and distal gripper control signals. In addition, the dataset also contains timestamps, frame indices, episode indices, task indices, and is_lost status markers. The dataset is structured with Parquet files, with a total data file size of 100 MB and a total video file size of 200 MB, and is suitable for research on robotic learning and control tasks.
