资源简介:
该数据集是使用LeRobot创建的机器人数据集,专为机器人任务设计。数据集包含3个episodes,总计1787帧,数据以parquet文件格式存储。机器人类型为bi_so_follower(双肩机器人),特征包括动作(action)和观测(observation),其中动作和状态观测均包含12个关节位置(如左肩平移、左肩提升、左肘弯曲等)。观测部分还包括来自三个摄像头的视频数据:左前摄像头(left_front_cam)、左手摄像头(left_hand_cam)和左侧摄像头(left_side_cam),每个视频分辨率为480x640,3通道,帧率为20fps,使用av1编解码器。数据集还包含时间戳、帧索引、episode索引等元数据。所有数据按chunk组织,每个chunk大小为1000帧,总数据文件大小为100MB,视频文件大小为200MB。数据集仅包含训练集(splits: train),适用于机器人控制和视觉任务的研究。

This dataset is a robot dataset created using LeRobot, specifically designed for robot tasks. It contains 3 episodes, totaling 1787 frames, and the data is stored in parquet file format. The robot type is bi_so_follower (bilateral shoulder robot), with features including actions and observations, where both actions and state observations consist of 12 joint positions (such as left shoulder translation, left shoulder elevation, left elbow flexion, etc.). The observation part also includes video data from three cameras: left front camera (left_front_cam), left hand camera (left_hand_cam), and left side camera (left_side_cam), each with a resolution of 480x640, 3 channels, a frame rate of 20fps, and using the av1 codec. The dataset also includes metadata such as timestamps, frame indices, and episode indices. All data is organized into chunks, with each chunk containing 1000 frames, and the total data file size is 100MB, with video files totaling 200MB. The dataset only includes a training set (splits: train) and is suitable for research in robot control and visual tasks.
