收藏资源简介:
该数据集是一个机器人数据集,由LeRobot创建,包含机械臂的动作和观测数据。具体特征包括:6维关节位置(如肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置),观测状态(同样为6维关节位置),以及来自顶部摄像头和腕部摄像头的视频观测(分辨率为480x640,30fps)。数据集还包含时间戳、帧索引、episode索引、任务索引等元数据。总共有100个episodes,38306帧,数据文件大小约100MB,视频文件大小约200MB。机器人类型为so_follower,主要用于训练和评估机器人控制算法。
This dataset is a robotics dataset created by LeRobot, containing action and observation data for a robotic arm. Specific features include: 6-dimensional joint positions (such as shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist rotation, and gripper position), observation states (also 6-dimensional joint positions), and video observations from a top camera and a wrist camera (resolution 480x640, 30fps). The dataset also includes metadata such as timestamps, frame indices, episode indices, and task indices. There are a total of 100 episodes, 38306 frames, with data file size approximately 100MB and video file size approximately 200MB. The robot type is so_follower, primarily used for training and evaluating robot control algorithms.
