收藏资源简介:
该数据集是一个机器人学数据集,使用LeRobot工具创建。它包含双臂机器人(bi_openarm_follower)的轨迹数据,具体包括:动作数据(16维浮点数,表示左右机械臂各7个关节和夹爪的位置)、观测状态数据(16维浮点数,与动作数据相同)、图像观测数据(来自左腕、前视和右腕的三个摄像头,视频格式,分辨率为480x640,帧率30fps,编码为av1,无音频),以及时间戳、帧索引、剧集索引、索引和任务索引等元数据。数据集总计1个剧集、875帧、1个任务,数据文件大小为100MB,视频文件大小为200MB,格式为parquet和mp4视频,采样频率为30Hz。
This is a robotics dataset constructed using the LeRobot toolkit. It encompasses trajectory data from the dual-arm robot bi_openarm_follower, including the following types of data: action data, which consists of 16-dimensional floating-point values representing the positions of 7 joints and the gripper for each of the left and right robotic arms; observation state data, which are 16-dimensional floating-point values identical to the action data; image observation data captured by three cameras mounted on the left wrist, front-facing position and right wrist respectively, with video resolution of 480×640, frame rate of 30 fps, AV1 encoding and no audio tracks; and metadata including timestamps, frame indices, episode indices, sample indices and task indices. In total, this dataset contains 1 episode, 875 frames and 1 task. The data files are 100MB in size, while the video files have a total size of 200MB. The dataset is stored in Parquet and MP4 formats, with a sampling frequency of 30 Hz.
