收藏资源简介:
该数据集由LeRobot创建,专用于机器人技术领域。它包含机器人的动作和观察数据,具体特征包括:动作数据(如肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置等6个浮点数值)、观察状态(与动作数据相同的关节位置)、图像观察(来自手腕摄像头和头顶摄像头的视频,分辨率分别为640x480和480x640,帧率为30fps,使用av1编解码器),以及时间戳、帧索引、回合索引、索引和任务索引等元数据。数据集总共有5个回合、1412帧和1个任务,数据以parquet文件格式存储,视频以mp4格式存储,机器人类型为so_follower。数据集结构支持训练分割,适用于机器人控制和学习任务。
This dataset was developed by LeRobot for exclusive use in the robotics domain. It encompasses robot action and observation data, with detailed features listed below: 1. Action data: 6 floating-point values covering shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist rotation, and gripper position; 2. Observation states: identical joint positions to those in the action data; 3. Image observations: videos captured by the wrist-mounted camera and the overhead camera, with resolutions of 640x480 and 480x640 respectively, a frame rate of 30 fps, and encoded with the av1 codec; Additional metadata includes timestamps, frame indices, episode indices, sample indices, and task indices. In total, the dataset contains 5 episodes, 1412 frames, and 1 task. The tabular data is stored in parquet file format, while the video files are stored in mp4 format. The target robot platform is so_follower. The dataset structure supports training data splits and is applicable to robot control and machine learning tasks.
