This is a robotics dataset developed using LeRobot, focusing on dual-arm manipulation tasks. It contains 270 episodes, totaling 131,749 frames at a frame rate of 30 fps. The dataset includes the following features: actions, which are 16-dimensional floating-point arrays representing the positions of 7 joints and the gripper for both the left and right robotic arms; state observations, which are 16-dimensional floating-point arrays identical to the action features; image observations, which are videos captured by the left wrist, base, and right wrist cameras, with a resolution of 480×640, 3 color channels, and encoded in AV1 format; as well as timestamps, frame indices, episode indices, indexes, and task indices. The dataset is divided into 3 tasks and licensed under the Apache 2.0 License. The data is stored in Parquet format, with a total data file size of 100 MB and a total video file size of 200 MB. The robotic platform type is bi_openarm_follower.
