收藏资源简介:
该数据集由LeRobot项目创建,专为机器人任务设计。它包含3,205个训练集片段,总计9,434,477帧数据,采样率为60fps。数据集记录了双机械臂(型号为yam)的14维关节状态观测(包括左/右臂的腰部、肩部、肘部、前臂滚动、手腕角度、手腕旋转和夹持器位置)、14维相应动作控制指令、来自三个摄像头(左腕、右腕和高位摄像头)的224x224分辨率RGB视频观测、时间戳、帧索引、片段索引、任务索引(共3个任务)、奖励信号和蒙特卡洛回报。数据以Parquet格式存储,视频以MP4格式存储,总数据量约100MB,视频文件约200MB。
This dataset was developed by the LeRobot project and is specifically designed for robotic tasks. It contains 3,205 training episodes, with a total of 9,434,477 frames of data at a sampling rate of 60fps. The dataset records 14-dimensional joint state observations of a dual-arm robotic arm (model: yam) — including the waist, shoulder, elbow, forearm roll, wrist angle, wrist rotation, and gripper position of the left and right arms — alongside 14-dimensional corresponding action control commands. It also includes RGB video observations at 224×224 resolution from three cameras (left wrist, right wrist, and overhead camera), timestamps, frame indices, episode indices, task indices (3 tasks in total), reward signals, and Monte Carlo returns. Non-video data is stored in Parquet format, while video files are stored in MP4 format. The total size of the non-video dataset is approximately 100 MB, and the total size of the video files is around 200 MB.
