<!-- 集成SLAM与导航,实现机器人自主移动的地图 -->
<launch>
<!-- 启动SLAM节点 -->
<include file="$(find nav_demo)/launch/nav01_slam_plus.launch" />
<!-- 运行move_base节点 -->

</launch>
step2: 编译+启动 gazebo 仿真环境
source ./devel/setup.bash
roslaunch mycar environment.launch
step3: 编译+启动 rviz
source ./devel/setup.bash
roslaunch nav_demo nav06_test.launch
