收藏资源简介:
该数据集由LeRobot创建,是一个机器人学数据集,专门用于双手机器人(ffw_sg2_rev1型号)的演示数据。数据集包含2个完整episodes、总计706帧、1个任务和6个视频。数据以30fps的帧率采集,包括多视角图像观测(头部摄像头分辨率376x672,左右腕部摄像头分辨率240x424)、19维关节状态观测(涵盖左右臂、夹爪、头部和升降关节)以及19维动作向量。数据以parquet格式存储,视频为mp4格式,适用于机器人模仿学习或强化学习任务。
This dataset, created by LeRobot, is a robotics dataset specifically designed for demonstration data of dual-arm robots with the model ffw_sg2_rev1. It contains 2 complete episodes, totaling 706 frames, 1 task, and 6 videos. The data was collected at a frame rate of 30 fps, including multi-view image observations: the head camera has a resolution of 376×672, while the left and right wrist cameras have a resolution of 240×424; 19-dimensional joint state observations covering the left and right arms, grippers, head, and lifting joints; and 19-dimensional action vectors. The data is stored in Parquet format, while the videos are in MP4 format. This dataset is suitable for robotic imitation learning or reinforcement learning tasks.
