资源简介:

该数据集是一个机器人领域的数据集,专门针对右臂机器人(robot_type: xlerobot_right_arm)记录的数据。数据集包含5个剧集(total_episodes: 5),总计2120帧(total_frames: 2120),帧率为20 fps。数据特征包括动作数据(action),涵盖右臂的6个关节位置(如肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置);状态观测(observation.state),同样包含这6个关节位置;图像观测(observation.images.center和observation.images.right),提供中心摄像头和右侧摄像头的视频数据,分辨率为480x640,3通道(RGB),视频编码为av1;此外,还有时间戳(timestamp)、帧索引(frame_index)、剧集索引(episode_index)、索引(index)和任务索引(task_index)。数据集以Parquet文件格式存储,视频文件以MP4格式存储,总数据文件大小为100 MB,视频文件大小为200 MB。该数据集适用于机器人控制、模仿学习或行为克隆等任务,由LeRobot工具创建。

This dataset is a robotics dataset specifically recorded for a right-arm robot (robot_type: xlerobot_right_arm). It contains 5 episodes (total_episodes: 5), with a total of 2120 frames (total_frames: 2120) at a frame rate of 20 fps. Data features include action data (action), covering 6 joint positions of the right arm (e.g., shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position); state observations (observation.state), also including these 6 joint positions; image observations (observation.images.center and observation.images.right), providing video data from center and right cameras with a resolution of 480x640, 3 channels (RGB), and video encoding as av1; additionally, there are timestamps (timestamp), frame indices (frame_index), episode indices (episode_index), indices (index), and task indices (task_index). The dataset is stored in Parquet file format, with video files in MP4 format, with a total data file size of 100 MB and video file size of 200 MB. It is suitable for tasks such as robot control, imitation learning, or behavior cloning, and was created by the LeRobot tool.
