资源简介:

该数据集由LeRobot创建,专注于机器人任务,具体涉及“horse_picking”(马匹拾取)场景。数据集包含50个episodes,总计25039帧,以parquet和mp4格式存储。数据特征包括:动作(6维浮点数组,表示机器人关节位置,如肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置)、观察状态(与动作相同的6维关节位置)、来自手腕和头顶摄像头的图像观察(视频格式,分辨率480x640,3通道RGB,30fps),以及时间戳、帧索引、episode索引、任务索引等元数据。机器人类型为“so_follower”。数据集用于训练和评估机器人控制算法,支持强化学习或模仿学习任务。

This dataset is created by LeRobot and focuses on robotic tasks, specifically involving the horse_picking scenario. It contains 50 episodes, totaling 25039 frames, stored in parquet and mp4 formats. Data features include: actions (a 6-dimensional floating-point array representing robot joint positions, such as shoulder translation, shoulder elevation, elbow bend, wrist bend, wrist rotation, and gripper position), observation states (the same 6-dimensional joint positions as actions), image observations from wrist and overhead cameras (video format, resolution 480x640, 3-channel RGB, 30fps), as well as metadata such as timestamps, frame index, episode index, and task index. The robot type is so_follower. The dataset is used for training and evaluating robot control algorithms, supporting reinforcement learning or imitation learning tasks.
