gazebo小车自主路径规划仿真
在之前的文章中完成了对地图的构建，接下来使用 Ros navgition完成机器人自主导航
首先是Ros navigation的下载安装
ros功能包：Navigation
ros wiki：http://wiki.ros.org/navigation
github 地址：https://github.com/ros-planning/navigation
在官网下载 Ros navigation到工作空间内。
cd ~/catkin_ws
catkin_make
在工作空间下创建mbot_navigation功能包
cd ~/catkin_ws/src
catkin_create_pkg mbot_navigation roscpp rospy std_msgs
创建launch文件等文件夹
cd mbot_navigation
mkdir -p launch
mkdir -p config
mkdir -p maps
mkdir -p rviz
launch文件下放launch文件，config文件夹下放navigation的配置参数文件，maps下是保存的map地图文件。

下来分别运行mbot_laser_nav_gazebo.launch和nav_cloister_demo.launch文章来源：https://www.toymoban.com/news/detail-542801.html
roslaunch mbot_navigation mbot_laser_nav_gazebo.launch
roslaunch mbot_navigation nav_cloister_demo.launch
这两个launch文件先打开gazebo后打开rviz，在rviz中使用2d_nav就可以进行路径规划了
