收藏资源简介:
该数据集由LeRobot创建,专用于机器人技术研究。它包含一个完整的episode,总计897帧,帧率为15fps。数据以parquet格式存储,视频以mp4格式存储。数据集针对UR(Universal Robots)机器人,记录了机器人的动作(包括肩部平移关节、肩部提升关节、肘关节、腕部1关节、腕部2关节、腕部3关节和夹爪关节的7个关节角度)和观测状态(相同的7个关节角度)。观测还包括来自三个视角的图像:侧面、手腕和顶部,每个图像的分辨率为480x640,3通道(RGB),使用av1编解码器。此外,数据集包含时间戳、帧索引、episode索引、任务索引等元数据。数据集仅包含训练分割(索引0到1),总数据文件大小为100MB,视频文件大小为200MB。
This dataset is created by LeRobot and is designed for robotics research. It contains a complete episode with a total of 897 frames at a frame rate of 15fps. The data is stored in parquet format, and videos are stored in mp4 format. The dataset targets UR (Universal Robots) robots, recording robot actions (including 7 joint angles: shoulder pan, shoulder lift, elbow, wrist 1, wrist 2, wrist 3, and gripper joints) and observation states (the same 7 joint angles). Observations also include images from three perspectives: side, wrist, and top, each with a resolution of 480x640, 3-channel (RGB), using the av1 codec. Additionally, the dataset contains metadata such as timestamps, frame index, episode index, and task index. The dataset only includes a training split (index 0 to 1), with a total data file size of 100MB and a video file size of 200MB.
