my_openarm_dataset_m5
收藏资源简介:
该数据集是一个机器人操作数据集,使用LeRobot工具创建。数据集包含53个训练任务片段(episodes),总计26362帧数据,以Parquet格式存储。数据特征包括机器人的动作指令和观测状态:动作(action)和观测状态(observation.state)均为8维浮点数数组,分别对应7个关节和1个夹爪的位置信息。观测部分还包含多视角视频数据:胸部摄像头(chest)提供848x480分辨率、30帧率的RGB视频;右腕摄像头(right_wrist)提供640x480分辨率、30帧率的RGB视频,视频均采用AV1编码。此外,数据集包含时间戳(timestamp)、帧索引(frame_index)、片段索引(episode_index)、数据索引(index)和任务索引(task_index)等元数据字段。数据集总大小约为300MB(其中数据文件100MB,视频文件200MB),适用于机器人模仿学习、强化学习、行为克隆等任务的研究与开发。
This dataset is a robot manipulation dataset created using the LeRobot tool. It contains 53 training task episodes, totaling 26,362 frames of data, stored in Parquet format. The data features include robot action commands and observation states: both the action and observation.state are 8-dimensional floating-point arrays, corresponding to the positions of 7 joints and 1 gripper. The observation part also includes multi-view video data: the chest camera provides RGB video at 848x480 resolution and 30 fps, while the right wrist camera provides RGB video at 640x480 resolution and 30 fps, with both videos encoded using AV1. Additionally, the dataset includes metadata fields such as timestamp, frame_index, episode_index, index, and task_index. The total dataset size is approximately 300MB (with 100MB for data files and 200MB for video files), and it is suitable for research and development in robot imitation learning, reinforcement learning, behavior cloning, and related tasks.
