收藏资源简介:
该数据集由LeRobot创建,专注于机器人学任务,具体涉及机器人操作与控制。数据集包含10个episodes,总计4489帧数据,以parquet格式存储,并附带mp4格式的视频文件。数据特征包括机器人的动作(6个关节位置:肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部旋转、夹爪位置)、状态观测(与动作相同的关节位置)、多视角图像观测(前视、左视和腕部摄像头,均为RGB视频,分辨率480x640,帧率30fps),以及时间戳、帧索引、episode索引、任务索引等元数据。机器人类型为so_follower,数据集总大小约300MB(数据100MB,视频200MB),适用于机器人学习、模仿学习或强化学习任务。
This dataset was developed by LeRobot, targeting robotics tasks with a focus on robot manipulation and control. It contains 10 episodes, totaling 4489 frames of data stored in Parquet format, alongside MP4-format video files. The dataset includes the following data features: robot actions (6 joint positions: shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist rotation, and gripper position), state observations (identical joint positions to the actions), multi-view image observations from front-facing, left-facing, and wrist cameras (all RGB videos with a resolution of 480x640 and a frame rate of 30fps), as well as metadata such as timestamps, frame index, episode index, and task index. The robot platform used is so_follower. The total size of the dataset is approximately 300 MB, with 100 MB being raw data and 200 MB being video files. This dataset is applicable to robotics learning, imitation learning, or reinforcement learning tasks.
