收藏资源简介:
该数据集由LeRobot创建,专用于机器人学任务。它包含10个训练片段,总计4489帧,涉及单个任务。数据集使用so_follower机器人类型,采集了动作数据(包括肩部、肘部、腕部和夹爪的位置)、观测状态(与动作数据相同),以及来自前视、左视和腕部摄像头的视频图像(分辨率为480x640,3通道RGB,帧率为30fps)。数据以parquet格式存储,总数据文件大小为100MB,视频文件大小为200MB。数据集结构包括时间戳、帧索引、片段索引、任务索引等元数据,适用于机器人控制和学习任务。
This dataset was created by LeRobot and is specifically designed for robotics tasks. It consists of 10 training episodes, totaling 4489 frames, and focuses on a single task. The dataset adopts the so_follower robot type, and collects action data (including positions of the shoulder, elbow, wrist and gripper), observation data identical to the action data, as well as video images captured by front-facing, left-facing and wrist-mounted cameras, with a resolution of 480×640, 3-channel RGB and a frame rate of 30 fps. The data is stored in Parquet format, with a total data file size of 100 MB and video file size of 200 MB. The dataset structure includes metadata such as timestamps, frame indices, episode indices, task indices and other relevant items, and is applicable to robot control and learning tasks.
