收藏资源简介:
这是一个由LeRobot创建的机器人学数据集,专注于三件装配任务。数据集使用UR5e机器人和Robotiq85Gripper夹爪,包含500个episodes和168,804帧,帧率为20fps。数据以parquet文件和视频格式存储,总数据文件大小为100MB,视频文件大小为200MB。数据集特征包括动作(7维浮点数组,表示dx、dy、dz、drx、dry、drz和夹爪控制)、观测(如状态、末端执行器位置和四元数、夹爪位置、关节位置)以及来自前视图和侧视图的图像观测(256x256 RGB视频)。数据集结构支持跨体现学习,适用于机器人控制和研究任务。
This is a robotics dataset developed by LeRobot, focusing on three assembly tasks. The dataset uses the UR5e robot and Robotiq85 Gripper, containing 500 episodes and 168,804 frames at a frame rate of 20 fps. The data is stored in both Parquet files and video formats, with a total size of 100 MB for the data files and 200 MB for the video files. The dataset features include actions (a 7-dimensional floating-point array representing dx, dy, dz, drx, dry, drz and gripper control), observations (such as states, end-effector position and quaternion, gripper position, joint positions), as well as image observations captured from front and side views (256×256 RGB videos). The structure of this dataset supports cross-embodiment learning, and is applicable to robotic control and research tasks.
