收藏资源简介:
该数据集是一个机器人学数据集,使用LeRobot创建,包含机器人动作和观察数据。数据集特征包括:动作(6个浮点值,对应肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置)、状态观察(与动作相同的6个浮点值)、图像观察(来自手腕摄像头,分辨率为480x640x3,和顶部摄像头,分辨率为480x848x3,均为视频格式)、时间戳、帧索引、episode索引、索引和任务索引。数据集总共有1个episode、693帧和1个任务,帧率为30fps,数据以parquet文件存储,视频文件为mp4格式,机器人类型为so_follower。数据分割为训练集(覆盖所有数据)。
This is a robotics dataset created using LeRobot, which contains robot action and observation data. The dataset features include: actions (6 floating-point values corresponding to shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist rotation and gripper position), state observations (6 identical floating-point values as the actions), image observations from the wrist camera with a resolution of 480x640x3 and the top camera with a resolution of 480x848x3, both in video format, as well as timestamps, frame indices, episode indices, indices and task indices. The dataset has a total of 1 episode, 693 frames and 1 task, with a frame rate of 30 fps. The data is stored in Parquet files, while the video files are in MP4 format. The robot type is so_follower. The dataset is split into a training set covering all data.
