收藏资源简介:
该数据集是一个机器人操作数据集,使用LeRobot框架创建。数据集包含机器人执行任务时的多模态记录,具体包括:1) 动作空间:6维关节位置控制指令(肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部旋转、夹爪位置);2) 观测空间:机器人6维关节位置状态,以及来自两个视角的视觉观测——前方摄像头图像和带标注的图像,均为480x640分辨率的RGB视频,帧率30fps;3) 元数据:时间戳、帧索引、回合索引、任务索引等。数据集总规模为1457帧,包含1个任务和1个完整回合。数据以Parquet文件格式存储,视频以MP4格式存储,总数据量约300MB。该数据集适用于机器人模仿学习、行为克隆、视觉运动策略学习等任务,特别针对关节位置控制型机器人(so_follower类型)的操作研究。
This dataset is a robotic manipulation dataset created using the LeRobot framework. It contains multimodal recordings of a robot performing tasks, including: 1) Action space: 6-dimensional joint position control commands (shoulder translation, shoulder lift, elbow bend, wrist bend, wrist rotation, gripper position); 2) Observation space: 6-dimensional joint position states of the robot, along with visual observations from two perspectives—front camera images and annotated images, both in 480x640 resolution RGB video at 30fps; 3) Metadata: timestamps, frame indices, episode indices, task indices, etc. The dataset totals 1457 frames, with 1 task and 1 complete episode. Data is stored in Parquet file format, videos in MP4 format, and the total data size is approximately 300MB. It is suitable for tasks such as robotic imitation learning, behavior cloning, and visual-motor policy learning, particularly for research on joint position-controlled robots (so_follower type).
