omx_pick_redb_20260531_130149
收藏资源简介:
该数据集是一个用于机器人学习的数据集,由LeRobot工具创建,专注于机器人抓取任务(推测从文件名omx_pick_redb),包含50个episodes和28860帧数据。数据集结构包括动作(如肩部平移、肩部提升、肘部弯曲等关节位置)、观察状态(机器人的关节位置)、场景图像(480x640分辨率RGB视频)和夹爪图像(同样分辨率视频),以及时间戳、帧索引、episode索引等元数据。机器人类型为omx_follower,数据以parquet文件格式存储,视频以mp4格式存储,适用于训练和评估机器人控制算法。
This dataset is designed for robot learning, created by LeRobot tool, focusing on robot grasping tasks (inferred from the filename omx_pick_redb). It contains 50 episodes and 28,860 frames of data. The dataset structure includes actions (such as joint positions like shoulder translation, shoulder lift, elbow bend), observation states (robot joint positions), scene images (480x640 resolution RGB videos), gripper images (videos with the same resolution), and metadata such as timestamps, frame indices, and episode indices. The robot type is omx_follower, with data stored in parquet file format and videos in mp4 format, suitable for training and evaluating robot control algorithms.
