lerobot_place_2
收藏资源简介:
该数据集是一个专门用于机器人任务的数据集,由LeRobot工具创建。它包含51个episodes,总计12841帧,主要用于训练目的。数据集结构涵盖动作特征(如关节位置和速度)、状态观察(如机器人关节和轮子位置)、以及来自前、侧、顶三个视角的图像视频观察(分辨率为480x640,帧率为30fps,采用H.264编码)。此外,还包括时间戳、帧索引、episode索引等元数据。该数据集适用于机器人控制和学习任务,并采用Apache 2.0许可证。
This is a specialized robotic task dataset developed by the LeRobot toolkit. It contains 51 episodes with a total of 12,841 frames, and is primarily intended for training purposes. The dataset structure covers action features (e.g., joint positions and velocities), state observations (e.g., positions of robot joints and wheels), and image/video observations from three perspectives: front, side, and top. The video data has a resolution of 480×640, a frame rate of 30 fps, and uses H.264 encoding. In addition, it also includes metadata such as timestamps, frame indices, and episode indices. This dataset is suitable for robotic control and learning tasks, and is released under the Apache 2.0 license.
