资源简介:
该数据集使用LeRobot创建,是一个机器人学数据集,专注于双机械臂折叠毛巾任务。数据集包含271个回合、261,134帧数据,帧率为30fps。特征包括16维动作向量(控制左右机械臂的7个关节和夹爪位置)、16维观测状态向量(与动作相同)、以及三个视角的图像观测(顶部、右腕部、左腕部),图像分辨率为480x640,格式为视频。数据以parquet文件和视频文件存储,总数据文件大小为100MB,视频文件大小为200MB。机器人类型为bi_openarm_follower,用于训练和验证机器人控制模型。
This dataset is created using LeRobot and is a robotics dataset focused on the task of dual-arm towel folding. It contains 271 episodes and 261,134 frames with a frame rate of 30fps. Features include a 16-dimensional action vector (controlling the 7 joints and gripper positions of both the left and right robotic arms), a 16-dimensional observation state vector (same as the action), and image observations from three perspectives (top, right wrist, left wrist) with a resolution of 480x640 in video format. The data is stored as parquet files and video files, with total data file size of 100MB and video file size of 200MB. The robot type is bi_openarm_follower, used for training and validating robot control models.
