收藏资源简介:
该数据集使用LeRobot创建,是一个机器人任务数据集,专注于机器人控制与观测。数据集包含50个episodes,总计18822帧,帧率为30fps。特征包括动作(action)和观测状态(observation.state),其中动作和状态均包含6个浮点型关节位置数据(如肩部平移、肩部抬升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置)。观测数据还包括来自两个摄像头的视频流:cam_top(顶部摄像头)和cam_wrist(腕部摄像头),视频分辨率为480x640,3通道(RGB),编码为av1,无音频。其他特征包括时间戳、帧索引、episode索引、任务索引等。数据集以parquet格式存储,总数据文件大小为100MB,视频文件大小为200MB。机器人类型为so_follower,适用于机器人学习和控制任务。
This dataset is created using LeRobot and is a robot task dataset focused on robot control and observation. It contains 50 episodes, totaling 18822 frames at a frame rate of 30fps. Features include action and observation.state, both containing 6 floating-point joint position data (e.g., shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position). Observation data also includes video streams from two cameras: cam_top (top camera) and cam_wrist (wrist camera), with video resolution of 480x640, 3 channels (RGB), encoded as av1, and no audio. Other features include timestamps, frame index, episode index, task index, etc. The dataset is stored in parquet format, with a total data file size of 100MB and video file size of 200MB. The robot type is so_follower, suitable for robot learning and control tasks.
