收藏资源简介:
该数据集使用LeRobot创建,专注于机器人学任务,包含机器人动作和观察数据。具体来说,动作数据包括6个关节位置:shoulder_pan.pos、shoulder_lift.pos、elbow_flex.pos、wrist_flex.pos、wrist_roll.pos和gripper.pos。观察数据包括状态信息(同样为6个关节位置)以及两个摄像头视频:overhead(俯视)和wrist(腕部)图像,每个视频分辨率为480x640,3通道,帧率为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50个episodes、18637帧,数据以parquet文件格式存储,总数据大小约100MB,视频文件大小约200MB。机器人类型为so_follower,适用于训练和评估机器人控制模型。
This dataset was created using LeRobot and focuses on robotics tasks, containing robot action and observation data. Specifically, the action data includes 6 joint positions: shoulder_pan.pos, shoulder_lift.pos, elbow_flex.pos, wrist_flex.pos, wrist_roll.pos, and gripper.pos. The observation data includes state information (also 6 joint positions) and two camera videos: overhead (top-down) and wrist (wrist-mounted) images, each with a resolution of 480x640, 3 channels, and a frame rate of 30fps. The dataset also includes metadata such as timestamps, frame indices, episode indices, and task indices. There are a total of 50 episodes and 18637 frames, with data stored in parquet file format, total data size approximately 100MB, and video file size about 200MB. The robot type is so_follower, suitable for training and evaluating robot control models.
