libero_goal_sawyer_additionalCams
收藏资源简介:
该数据集是一个使用LeRobot创建的机器人学数据集,专门针对Sawyer机器人,并包含额外的摄像头视角。数据集包含40个训练片段,总计3594帧,覆盖2个任务。数据以20帧每秒的速率采集,包括观察状态(如末端执行器状态、关节状态和夹爪状态)、来自前视图和侧视图的图像(分辨率为256x256,RGB格式),以及动作数据(7维向量)。数据集以Parquet文件形式存储,并附带视频文件,适用于机器人控制和模仿学习任务。
This dataset is a robotics dataset created using LeRobot, specifically designed for the Sawyer robot and includes additional camera perspectives. It contains 40 training episodes, totaling 3594 frames, covering 2 tasks. Data is collected at a rate of 20 frames per second, including observation states (such as end-effector state, joint state, and gripper state), images from front and side views (with a resolution of 256x256 in RGB format), and action data (7-dimensional vectors). The dataset is stored in Parquet file format and comes with video files, making it suitable for robot control and imitation learning tasks.
