资源简介:
该数据集是通过LeRobot创建的,主要用于机器人技术领域。数据集包含2个episodes,596帧,1个任务和8个视频。数据以parquet格式存储,视频分辨率为480x640,帧率为30fps。数据集包含机器人的动作和观察状态信息,动作和状态信息均为18维的浮点数组,分别对应左右机械臂的各个关节角度和夹爪状态。视频数据来自四个不同的摄像头视角:高摄像头、低摄像头、左腕摄像头和右腕摄像头。
This dataset was developed using LeRobot and is primarily intended for robotics research. It consists of 2 episodes, 596 frames, 1 task, and 8 video clips. The data is stored in Parquet format, with the videos having a resolution of 480×640 and a frame rate of 30 fps. The dataset includes robot action and observation state information, where both the action and state data are 18-dimensional floating-point arrays corresponding to the joint angles and gripper states of the left and right robotic arms respectively. The video data is captured from four distinct camera perspectives: high-angle camera, low-angle camera, left-wrist camera, and right-wrist camera.
