收藏资源简介:
该数据集由LeRobot创建,是一个机器人控制数据集,专注于连续动作任务。它包含一个回合(episode)的138帧数据,帧率为30fps。特征包括:动作(action)和观察状态(observation.state),均为6维浮点数组,对应机器人关节位置(如肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置);观察图像包括顶部视角(observation.images.top)和夹爪视角(observation.images.gripper)的视频,分辨率为480x640,编码为AV1格式。此外,还包含时间戳、帧索引、回合索引、索引和任务索引等元数据。机器人类型为so_follower,数据以parquet和mp4视频文件格式存储,总数据大小约为300MB。
This dataset is created by LeRobot and focuses on robot control for continuous action tasks. It contains 138 frames of data from one episode at a frame rate of 30fps. Features include: action and observation.state, both as 6-dimensional float arrays corresponding to robot joint positions (e.g., shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position); observation images include video from a top view (observation.images.top) and a gripper view (observation.images.gripper) with a resolution of 480x640, encoded in AV1 format. Additionally, metadata such as timestamps, frame index, episode index, index, and task index are included. The robot type is so_follower, and the data is stored in parquet and mp4 video file formats, with a total size of approximately 300MB.
