资源简介:
该数据集是一个机器人操作数据集,专门用于巧克力拾取和放置任务。它包含50个训练集片段,总计29178帧数据,帧率为每秒30帧。数据集记录了机器人执行任务时的动作、关节状态以及来自手腕摄像头和头顶摄像头的视频观测。动作数据包括6个关节位置(肩部平移、肩部升降、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置),观测状态同样包含这6个关节位置。视频数据以H.264编码的MP4格式存储,分辨率为480x640像素,无音频。数据集以parquet文件格式组织,总数据文件大小为100MB,视频文件大小为200MB。该数据集适用于机器人学习、模仿学习或强化学习的研究和应用。
This dataset is a robotic manipulation dataset specifically designed for chocolate pick-and-place tasks. It includes 50 training episodes, totaling 29178 frames with a frame rate of 30 frames per second. The dataset records robot actions, joint states, and video observations from wrist and overhead cameras during task execution. Action data consists of 6 joint positions (shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position), with observation states also including these 6 joint positions. Video data is stored in H.264 encoded MP4 format, with a resolution of 480x640 pixels and no audio. The dataset is organized in parquet file format, with a total data file size of 100MB and video file size of 200MB. It is suitable for research and applications in robotic learning, imitation learning, or reinforcement learning.
