资源简介:
该数据集由LeRobot创建,专为机器人控制任务研究设计。它包含50个训练集片段,总帧数达29939帧,帧率为30fps,采用Apache 2.0许可证。数据集结构丰富,包括动作特征(以7维浮点数组表示,对应机器人关节位置)、观测状态特征(同样为7维浮点数组,对应机器人关节位置)、前视和侧视图像观测(格式为480x640 RGB视频,30fps,使用AV1编码),以及时间戳、帧索引、片段索引等元数据。机器人类型为so_follower,数据以Parquet格式存储,视频以MP4格式存储,适用于机器人学习和控制算法的开发与评估。
This dataset is created by LeRobot for research on robot control tasks. It includes 50 training segments with a total of 29,939 frames at a frame rate of 30fps, licensed under Apache 2.0. The dataset structure comprises action features (7-dimensional floating-point arrays corresponding to robot joint positions), observation state features (7-dimensional floating-point arrays corresponding to robot joint positions), front and side view image observations (480x640 RGB video at 30fps, encoded with AV1), as well as metadata such as timestamps, frame indices, and segment indices. The robot type is so_follower, with data stored in Parquet format and videos in MP4 format, suitable for the development and evaluation of robot learning and control algorithms.
