收藏资源简介:
该数据集是通过LeRobot创建的机器人数据集,包含10个episodes,总计4489帧。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(6维关节位置,具体为肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转、夹爪位置)、观测状态(6维关节位置)以及三个视角的图像观测(正面、左侧、腕部,均为480x640x3的视频,帧率为30fps)。其他元数据包括时间戳、帧索引、episode索引、索引和任务索引。数据集用于机器人任务,机器人类型为so_follower,采样频率为30fps,数据以Parquet格式存储,视频以MP4格式存储。
This robot dataset is constructed using LeRobot, consisting of 10 episodes with a total of 4489 frames. The size of the tabular data files is 100 MB, while the video files occupy 200 MB. The dataset features include action annotations (6-dimensional joint positions, specifically shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position), observation states (6-dimensional joint positions), and image observations from three perspectives: front, left, and wrist. All videos are in 480×640×3 resolution with a frame rate of 30 fps. Additional metadata includes timestamps, frame indices, episode indices, indices, and task indices. This dataset is intended for robotic tasks using the so_follower robot platform, with a sampling frequency of 30 fps. The tabular data is stored in Parquet format, and the videos are stored in MP4 format.
