play_robot_v3_1

该数据集是一个用于机器人技术的数据集，由LeRobot工具创建。它包含Trossen AI Stationary机器人的数据，具体包括1个episode、17932帧和2个视频。数据以Parquet文件格式存储，视频以MP4格式存储，帧率为30fps。数据集的特征涵盖机器人的动作（7个关节的浮点值）、观察状态（7个关节的浮点值）以及来自两个摄像头的图像观察：cam_high和cam_right_wrist，每个摄像头的视频分辨率为480x640像素，3个通道。此外，还包括时间戳、帧索引、episode索引等元数据。数据集适用于机器人控制、强化学习或计算机视觉任务，主要用于训练和评估机器人模型。This dataset is designed for robotics and created by the LeRobot tool. It contains data from the Trossen AI Stationary robot, including 1 episode, 17932 frames, and 2 videos. The data is stored in Parquet file format, with videos in MP4 format at a frame rate of 30fps. The dataset features robot actions (floating-point values for 7 joints), observation states (floating-point values for 7 joints), and image observations from two cameras: cam_high and cam_right_wrist, each with video resolution of 480x640 pixels and 3 channels. Additionally, metadata such as timestamps, frame indices, and episode indices are included. The dataset is suitable for robot control, reinforcement learning, or computer vision tasks, primarily used for training and evaluating robot models.
