This dataset was developed by LeRobot, distributed under the Apache-2.0 license, and falls within the field of robotics. It consists of 5 total segments, 1541 frames, and covers 1 overall task. The total size of the data files is 100 MB, while the video files amount to 200 MB, with a frame rate of 21 fps. The tabular data is stored in Parquet format, and the videos are in MP4 format. The dataset structure includes actions, observation states, image data from two cameras, as well as features such as timestamps, frame indices, segment indices, indexes, and task indices. Both actions and observation states contain 7 floating-point position values. The image data has a resolution of 480×640 with 3 channels; the videos are encoded with AV1, use the YUV420p pixel format, and have no audio tracks. This dataset is applicable to research on robot control and visual tasks.
