eval_take16
收藏资源简介:
该数据集由LeRobot创建,专注于机器人学领域,特别针对MobileAI机器人。它包含一个训练集,总共有1个episode、1031帧和1个任务。数据以parquet格式存储,并附带视频文件。特征包括动作数据(一个16维浮点数组,表示左右关节的位置和速度)、状态观察数据(同样为16维浮点数组),以及来自三个摄像头的图像观察数据(cam_high、cam_left_wrist、cam_right_wrist),每个视频的分辨率为480x640,3个通道,帧率为30fps。此外,数据集还包含时间戳、帧索引、episode索引、索引和任务索引等元数据。许可证为Apache-2.0,适用于机器人控制和视觉任务的研究。
This dataset is created via LeRobot, focusing on the field of robotics, specifically for MobileAI robots. It contains a training set with a total of 1 episode, 1031 frames, and 1 task. The data is stored in parquet format and comes with video files. Features include action data (a 16-dimensional float array representing left and right joint positions and velocities), state observation data (the same 16-dimensional float array), and image observation data from three cameras (cam_high, cam_left_wrist, cam_right_wrist), each video with a resolution of 480x640, 3 channels, and 30fps. Additionally, metadata such as timestamps, frame indices, episode indices, indices, and task indices are included. The dataset is licensed under Apache-2.0 and is suitable for research in robot control and visual tasks.
