This dataset is a robotics dataset created using the LeRobot tool in the MuJoCo simulation environment, focusing on manipulation tasks with dual-arm robots (xarm7). The core content involves the three cubes task, which may include simulated scenarios of the robot arms interacting with multiple cubes. The data scale comprises 16 complete episodes, totaling 30,660 data frames with a sampling frequency of 50 Hz. The data is stored in Parquet file format and includes corresponding video files. The dataset provides multimodal observation information: including 16-dimensional floating-point action vectors and observation state vectors; joint positions (54-dimensional) and joint velocities (50-dimensional) in the simulator; and RGB video observations from four cameras, located at the right wrist, left wrist, and two side perspectives, each video frame with a resolution of 300x480 pixels and 3 channels. Additionally, the dataset includes metadata fields such as timestamps, frame indices, episode indices, and task indices. This dataset is suitable for tasks such as robot imitation learning, reinforcement learning, and policy learning, particularly for research on object manipulation and coordinated control of dual-arm robots in simulated environments. The dataset is licensed under Apache 2.0.
