资源简介:
该数据集是一个机器人学习数据集,使用LeRobot工具创建。它包含双机械臂(bi_so_follower类型)的动作和观察数据。数据特征包括:12维的动作向量(对应左右机械臂的肩部、肘部、腕部关节位置以及夹爪位置),12维的状态观察向量(与动作向量相同),以及来自三个摄像头的视频观察(left_left_wrist、left_top、right_right_wrist,分辨率均为720x1280,30fps,RGB格式)。数据集还包含时间戳、帧索引、episode索引等元数据。总共有52个episodes,137930帧,数据以parquet格式存储,视频以mp4格式存储。数据集适用于机器人控制、模仿学习等任务。
This dataset is a robot learning dataset created using the LeRobot tool. It contains action and observation data for a dual robotic arm (bi_so_follower type). Data features include: a 12-dimensional action vector (corresponding to shoulder, elbow, wrist joint positions and gripper positions for both left and right arms), a 12-dimensional state observation vector (same as the action vector), and video observations from three cameras (left_left_wrist, left_top, right_right_wrist, all with a resolution of 720x1280, 30fps, RGB format). The dataset also includes metadata such as timestamps, frame indices, and episode indices. There are a total of 52 episodes and 137,930 frames. Data is stored in parquet format, and videos are stored in mp4 format. The dataset is suitable for tasks such as robot control and imitation learning.
