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
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。

mkdir maps//在这个文件夹下保存构建好的地图
cd ~/catkin_ws
catkin_make
source devel/setup.bash
下来分别运行mbot_laser_nav_gazebo.launch和nav_cloister_demo.launch
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
