This dataset is designed for robotic learning research, specifically targeting dual-arm robotic manipulation control tasks, and was created using the LeRobot toolkit. The dataset contains 6 complete episodes, totaling 4256 frames, focused on one specific task. The robotic platform used is the starpilot_yam_gripper. The dataset includes the following data modalities: 1. Action data: a 14-dimensional floating-point array representing the poses and gripper widths of the two robotic arms; 2. Observation state data: a 32-dimensional floating-point array, which includes the encoder angles of the two robotic arms, IMU linear acceleration and angular velocity, pose coordinates and quaternions, as well as the opening/closing status and separation distance of the grippers; 3. Multi-camera video observations: including RGB and depth images from the left wrist camera, right wrist camera, and base camera, with resolutions of 480x640 or 768x1024 and a frame rate of 30 fps. The tabular data is stored in Parquet format, while the video files are in MP4 format. The total data volume is approximately 100 MB, with the video files accounting for about 200 MB. This dataset is applicable to research in robotic control, imitation learning, and reinforcement learning.
