This dataset is a robot demonstration dataset created using the LeRobot tool, focusing on manipulation tasks with the Franka Panda robotic arm. It includes actions, observation states (such as joint positions, velocities, end-effector poses), images (wrist camera and depth images with a resolution of 480x640 and a frame rate of 14fps), as well as metadata like timestamps, frame indices, and episode indices. The dataset consists of 5 episodes and 2530 frames, covering a single task, with data stored in Parquet format and videos in MP4 format. It is suitable for robot learning and control research, supporting model training and validation.
