资源简介:
该数据集是一个用于机器人学习的双臂机器人数据集,基于LeRobot平台创建,专门针对so101双跟随者机器人类型。数据集包含2个总片段和594个总帧数,帧率为30 fps。数据特征包括动作(12个浮点型数值,对应左右臂的12个关节位置,如肩部、肘部、手腕和夹爪位置)、观察状态(同样12个关节位置)、以及来自顶部RealSense摄像头和左右手腕摄像头的视频观察(分辨率为480x640,3通道彩色视频,使用av1编解码器)。此外,数据集还包括时间戳、帧索引、片段索引、索引、任务索引等元数据。数据以parquet文件格式存储,视频以mp4格式存储,总数据文件大小为100 MB,视频文件大小为200 MB。数据集适用于训练和评估机器人控制算法,特别是双臂协调任务。
This dataset is a dual-arm robotic dataset for robot learning, developed based on the LeRobot platform, specifically targeting the so101 dual-follower robot type. It contains a total of 2 segments and 594 frames, with a frame rate of 30 fps. The data features include actions (12 floating-point values corresponding to the 12 joint positions of the left and right arms, such as shoulder, elbow, wrist and gripper positions), observation states (also 12 joint positions), as well as visual observations from the top RealSense camera and left/right wrist cameras with a resolution of 480x640, 3-channel color video using the av1 codec. Additionally, the dataset includes metadata such as timestamps, frame indices, segment indices, index and task indices. The data is stored in parquet file format, while the videos are stored in mp4 format. The total size of the data files is 100 MB, and the total size of the video files is 200 MB. This dataset is suitable for training and evaluating robotic control algorithms, especially for dual-arm coordination tasks.
