Created by the LeRobot project, this open-source robotics dataset is licensed under the Apache-2.0 license. It is primarily designed for research and development of robotic manipulation tasks, and contains multimodal observational data and control commands collected during the robot's task execution. The dataset consists of 151 independent task execution segments, with a total of 115,398 frames of data. Each data sample includes: 6-dimensional joint position action commands for the robot; 6-dimensional joint position state observations of the robot's body; RGB video observations captured by a top-down camera and a wrist-mounted camera, with a resolution of 640×480, a frame rate of 30 FPS, and encoded in the AV1 format; and metadata including timestamps, frame indices, segment indices, data indices, and task indices. The data is stored in chunked files, with a total non-video data file size of approximately 100 MB and a total video file size of around 200 MB. Currently, the dataset only includes a training set, and is applicable to research on tasks such as robotic imitation learning, reinforcement learning, and vision-action mapping.
