收藏资源简介:
该数据集是使用LeRobot创建的机器人数据集,专注于机器人控制任务。它包含机器人的动作和观察数据:动作由6个浮点值组成,包括肩部旋转、肩部提升、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置;观察状态同样包含这6个位置值,以及前摄像头采集的视频图像(分辨率为480x640,3通道,帧率30fps)。数据集还包括时间戳、帧索引、episode索引、索引和任务索引等元数据。总共有1个episode、1792帧和1个任务,数据以parquet文件格式存储,视频以mp4格式存储,机器人类型为so_follower。该数据集适用于机器人学习和控制研究。
This dataset is a robot dataset created using LeRobot, focusing on robot control tasks. It contains robot action and observation data: actions consist of 6 floating-point values including shoulder rotation, shoulder lift, elbow bend, wrist bend, wrist rotation, and gripper position; observation states similarly include these 6 position values, along with video images captured by a front camera (resolution 480x640, 3 channels, frame rate 30fps). The dataset also includes metadata such as timestamps, frame index, episode index, index, and task index. There are a total of 1 episode, 1792 frames, and 1 task, with data stored in parquet file format and videos in mp4 format, and the robot type is so_follower. This dataset is suitable for robot learning and control research.
