资源简介:
该数据集是一个机器人学数据集,使用LeRobot创建,专为移动AI机器人设计。数据集包含1个完整的情节,总计1069帧,帧率为30fps。数据以Parquet文件格式存储,总数据文件大小为100MB,视频文件大小为200MB。特征包括动作数据(16维浮点数组,表示左右关节位置和速度)、观测状态(16维浮点数组,与动作数据类似)、以及来自三个摄像头的图像观测(cam_high、cam_left_wrist、cam_right_wrist),每个视频分辨率为480x640,3通道,编码为AV1格式。数据集还包括时间戳、帧索引、情节索引等元数据。所有数据仅用于训练分割,适用于机器人控制和学习任务。
This dataset is a robotics dataset created using LeRobot, specifically designed for mobile AI robots. It contains 1 complete episode, totaling 1069 frames with a frame rate of 30fps. The data is stored in Parquet file format, with a total data file size of 100MB and video file size of 200MB. Features include action data (16-dimensional floating-point arrays representing left and right joint positions and velocities), observation states (16-dimensional floating-point arrays, similar to action data), and image observations from three cameras (cam_high, cam_left_wrist, cam_right_wrist), each with a resolution of 480x640, 3 channels, encoded in AV1 format. The dataset also includes metadata such as timestamps, frame indices, and episode indices. All data is intended for training splits and is suitable for robot control and learning tasks.
