资源简介:
该数据集是一个机器人学数据集,专门用于so_follower机器人类型,使用LeRobot工具创建。数据集包含75个episodes,总计24116帧,涉及一个任务。数据以Parquet文件格式存储,视频文件为MP4格式,帧率为30fps。数据集的特征包括:动作特征(6个浮点数,表示肩部平移、肩部升降、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置)、观测状态特征(与动作相同的6个关节位置)、两个图像观测特征(分别来自head和table视角的RGB视频,分辨率均为480x640,3个通道),以及时间戳、帧索引、episode索引、索引和任务索引等元数据。数据集仅包含训练集,适用于机器人控制和学习任务。
This dataset is a robotics dataset specifically designed for the so_follower robot type, created using the LeRobot tool. It contains 75 episodes, totaling 24116 frames, and involves one task. The data is stored in Parquet file format, with video files in MP4 format at a frame rate of 30fps. The dataset features include: action features (6 floating-point numbers representing shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position), observation state features (the same 6 joint positions as the actions), two image observation features (RGB videos from head and table perspectives, each with a resolution of 480x640 and 3 channels), as well as metadata such as timestamps, frame index, episode index, index, and task index. The dataset only includes a training set and is suitable for robot control and learning tasks.
