关键词：

之前博文已经介绍过机器人exploration以及多机器人SLAM map merage《ROS学习笔记之——多机器人探索环境》《ROS仿真笔记之——基于gazebo的多机器人探索环境仿真》《ROS仿真笔记之——多移动机器人SLAM地图融合》《ROS仿真笔记之——移动机器人自主探索式地图构建》之前的都是基于功能包（http://wiki.ros.org/multirobot_map_merge/）

而本博文基于rrt_exploration包来进行仿真。网上也有大把基于此包的博客。但是本人实现时都无法跑动（可能是版本的原因？老显示tf无法链）为此，更改了原包的机器人模型为turtlebot3 waffle并且调了一些路径规划的参数，终于调出来了，效果如下视频所示～

single kobuki robot slam based on rrt

单机器人自主探索建图

单机器人自主探索建图(1)

换成kobuki模型效果好很多～

运行命令：

roslaunch rrt_exploration_tutorials single_simulated_house.launch
roslaunch rrt_exploration single.launch

注意要保证move base的开启
