收藏资源简介:
该数据集由LeRobot创建,专为机器人学习和控制任务设计,包含251个episodes,总计176794帧数据,覆盖4个不同任务。数据集结构包括动作特征和观察特征:动作特征由6个浮点值组成,表示机器人关节位置(如肩部平移、肩部升降、肘部弯曲、手腕弯曲、手腕滚动和夹爪位置);观察特征包括状态(与动作相同的6个关节位置)和图像数据,其中图像数据来自两个视角:俯视摄像头(overhead)和手腕摄像头(wrist),均为视频格式,分辨率480x640,3通道,帧率30fps。此外,数据集还包含时间戳、帧索引、episode索引等元数据。数据以Parquet文件存储,总数据大小约100MB,视频文件大小约200MB,适用于机器人模仿学习或强化学习研究。
This dataset was developed by LeRobot, specially designed for robot learning and control tasks. It contains 251 episodes, totaling 176,794 frames, covering 4 distinct tasks. The dataset structure includes action features and observation features: the action features consist of 6 floating-point values, representing the robot's joint positions such as shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist roll and gripper position; the observation features include states (the same 6 joint positions as the action features) and image data. The image data comes from two viewpoints: overhead camera and wrist camera, both in video format with a resolution of 480×640, 3 channels and a frame rate of 30 fps. Additionally, the dataset also contains metadata such as timestamps, frame indices and episode indices. The data is stored in Parquet files, with a total data size of approximately 100 MB, and the video files amount to about 200 MB. This dataset is suitable for research on robot imitation learning or reinforcement learning.
