资源简介:
该数据集是一个由LeRobot创建的机器人任务数据集,专门用于机器人学习和控制任务。数据集包含3个episodes,总计1794帧数据,帧率为20fps。数据以parquet格式存储,视频数据以mp4格式存储。机器人类型为“bi_so_follower”,特征包括动作和观测两部分:动作数据由12个浮点数值组成,分别代表左右机械臂的12个关节位置,具体包括左肩平移、左肩提升、左肘弯曲、左腕弯曲、左腕旋转、左夹爪位置,以及右侧对应的关节;观测数据包括状态观测和图像观测,状态观测同样包含12个浮点数值,对应机械臂的关节位置,图像观测来自三个摄像头(左前摄像头、左手摄像头和左侧摄像头),每个视频的分辨率为480x640像素,3通道(RGB),使用av1编解码器。此外,数据集还包含时间戳、帧索引、episode索引、索引和任务索引等元数据,以支持数据分析和模型训练。
This dataset is a robotic task dataset created by LeRobot, specifically designed for robot learning and control tasks. It contains 3 episodes with a total of 1794 frames at a frame rate of 20fps. The data is stored in parquet format, and video data is stored in mp4 format. The robot type is bi_so_follower, and features include action and observation components: action data consists of 12 floating-point values representing the joint positions of the left and right robotic arms, specifically including left shoulder translation, left shoulder elevation, left elbow flexion, left wrist flexion, left wrist rotation, left gripper position, and corresponding joints on the right side; observation data includes state observations and image observations, with state observations also containing 12 floating-point values corresponding to joint positions of the robotic arms, and image observations from three cameras (left front camera, left hand camera, and left side camera), each video with a resolution of 480x640 pixels, 3 channels (RGB), using the av1 codec. Additionally, the dataset includes metadata such as timestamps, frame indices, episode indices, indices, and task indices to support data analysis and model training.
