收藏资源简介:
该数据集由LeRobot创建,是一个用于机器人学的数据集,专门针对Yamaha双手机器人(yam_bimanual)。数据集包含427个训练片段,总计918,650帧,视频以30帧/秒录制。涵盖5个不同任务,提供多模态数据:包括机器人状态观测(32维浮点向量,包含左右机械臂的位置、旋转6D表示、夹爪状态和关节角度)、动作数据(同样为32维浮点向量),以及三个视频流观测(头部摄像头、左腕摄像头和右腕摄像头,每个视频分辨率为640x360,3通道,H.264编码)。数据以Parquet格式存储,并包含时间戳、帧索引、片段索引等元数据。
This dataset is created by LeRobot and is designed for robotics, specifically targeting the Yamaha bimanual robot (yam_bimanual). It contains 427 training episodes, totaling 918,650 frames, with videos recorded at 30 frames per second. It covers 5 different tasks and provides multimodal data: including robot state observations (a 32-dimensional floating-point vector containing the position, 6D rotation representation, gripper state, and joint angles of the left and right arms), action data (also a 32-dimensional floating-point vector), and three video stream observations (head camera, left wrist camera, and right wrist camera, each with a resolution of 640x360, 3 channels, H.264 encoded). The data is stored in Parquet format and includes metadata such as timestamps, frame indices, and episode indices.
