train_triple_fps15
收藏资源简介:
该数据集是一个机器人控制数据集,使用LeRobot创建,包含UR(通用机器人)的30个episodes,总计8532帧,帧率为15fps。数据特征包括:动作(7个关节角度:肩部平移、肩部提升、肘部、腕部1、腕部2、腕部3和夹爪关节)、观测状态(相同的7个关节角度)、以及三个视角的图像观测(侧视、腕部和顶部,均为480x640分辨率的RGB视频,编码为av1)。数据集仅用于训练,以Parquet格式存储,总数据文件大小为100MB,视频文件大小为200MB。
This dataset is a robot control dataset created using LeRobot, containing 30 episodes of UR (Universal Robot) with a total of 8532 frames at a frame rate of 15fps. The data features include: actions (7 joint angles: shoulder pan, shoulder lift, elbow, wrist 1, wrist 2, wrist 3, and gripper joint), observation states (the same 7 joint angles), and image observations from three perspectives (side view, wrist view, and top view, all as 480x640 resolution RGB videos encoded as av1). The dataset is intended only for training, stored in Parquet format, with a total data file size of 100MB and video file size of 200MB.
