train-3
收藏资源简介:
该数据集由LeRobot创建,专门用于机器人学任务。它包括10个episodes,总计4830帧数据,采用30fps的帧率记录。数据集基于UR机器人,以parquet文件格式存储,并包含对应的mp4视频文件。特征涵盖7维关节空间动作(如肩部平移、肩部提升、肘部、腕部1-3关节和夹爪关节)以及对应的7维状态观测。此外,提供来自手腕和侧面摄像头的视频观测,分辨率为480x640,3通道彩色图像。元信息包括时间戳、帧索引、episode索引、全局索引和任务索引,以支持数据分析和机器学习应用。
This dataset is created by LeRobot for robotics tasks. It consists of 10 episodes with a total of 4830 frames recorded at 30fps. The dataset uses a UR robot, stored in parquet file format along with corresponding mp4 video files. Features include 7-dimensional joint space actions (such as shoulder pan, shoulder lift, elbow, wrist 1-3 joints, and gripper joint) and corresponding 7-dimensional state observations. Additionally, video observations from wrist and side cameras are provided with a resolution of 480x640 and 3-channel color images. Metadata includes timestamps, frame index, episode index, global index, and task index.
