资源简介:
该数据集是一个机器人操作数据集,专注于球拾取任务,使用LeRobot工具创建。数据集包含Unitree_G1_Brainco机器人的操作记录,总共有16个episodes和2567帧数据,帧率为30fps。数据以parquet格式存储,视频以mp4格式存储。特征包括机器人的状态观测(26个浮点数,代表左右肩、肘、腕和手指的关节角度)、动作(相同维度的控制命令)、来自左侧高清摄像头的图像观测(分辨率480x640,3通道RGB视频),以及时间戳、帧索引、episode索引等元数据。数据集适用于机器人学习、模仿学习或强化学习任务,旨在支持机器人抓取和操作研究。
This dataset is a robot manipulation dataset focused on ball-picking tasks, created using the LeRobot tool. It contains operational records from the Unitree_G1_Brainco robot, with a total of 16 episodes and 2567 frames at a frame rate of 30fps. The data is stored in parquet format, and videos are stored in mp4 format. Features include robot state observations (26 floating-point numbers representing joint angles for left and right shoulders, elbows, wrists, and fingers), actions (control commands of the same dimension), image observations from a left-side high-definition camera (resolution 480x640, 3-channel RGB video), as well as metadata such as timestamps, frame indices, and episode indices. The dataset is suitable for robot learning, imitation learning, or reinforcement learning tasks, aiming to support research in robot grasping and manipulation.
