收藏资源简介:
该数据集使用LeRobot工具创建,是一个机器人学数据集,包含3个episodes和3323帧数据,针对omx_follower机器人类型。数据集结构包括动作数据(6个关节位置)、观察状态(6个关节位置)、以及来自腕部和顶部摄像头的视频观察(分辨率480x640,30fps),并附带时间戳、帧索引、episode索引等元数据。数据以Parquet文件格式存储,视频以MP4格式存储,总数据大小为100MB,视频大小为200MB。
This dataset is a robotics dataset developed with the LeRobot toolkit, tailored for the omx_follower robot type. It comprises 3 episodes and 3323 frames of data. The dataset structure includes action data (6 joint positions), observation states (6 joint positions), video observations captured by the wrist and top cameras (with a resolution of 480×640 and a frame rate of 30 fps), as well as metadata such as timestamps, frame indices, and episode indices. The tabular data is stored in Parquet file format, while the video files are stored in MP4 format. The total size of the tabular data is 100 MB, and the total size of the video files is 200 MB.
