rollout_pick_n_place_dagger_r16
收藏资源简介:
这是一个使用LeRobot创建的机器人学数据集,专注于拾取和放置任务。数据集包含一个剧集,总帧数为22570,帧率为30 fps。数据特征包括动作(6个浮点值,对应机器人关节位置如肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕滚动和夹爪位置)、观测状态(与动作相同的6个浮点值)、图像观测(包括前视图、注释视图和目标补丁视图,均为480x640分辨率、3通道的视频数据),以及元数据如时间戳、帧索引、剧集索引、索引和任务索引。数据集以Parquet格式存储,视频以MP4格式存储,适用于机器人控制和模仿学习任务。
This is a robotics dataset created using LeRobot, focusing on pick-and-place tasks. The dataset contains one episode, with a total of 22,570 frames and a frame rate of 30 fps. The data features include actions (6 floating-point values corresponding to robot joint positions: shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist roll, and gripper position), observation states (the same 6 floating-point values as the actions), image observations (including front view, annotated view, and target patch view, all of which are 3-channel video data with a resolution of 480x640), as well as metadata such as timestamps, frame indices, episode indices, indices, and task indices. The dataset is stored in Parquet format, while the videos are stored in MP4 format, and it is suitable for robotic control and imitation learning tasks.
