前期准备工作，创工作空间 共享无线 最重要的是地图。
Remote PC
master是整个ROS运行的核心，它主要的功能就是登记注册节点、服务和话题的名称，并维护一个参数服务器。
- cd catkin_ws
- source devel/setup.bash
- roscore
TurtleBot
启动turtlebot3仿真模型， 真实传感器，串口通信等。

- roslaunch turtlebot3_teleop turtlebot3_teleop_key.launch
turtlebot3_robot.launch
turtlebot3_core.launch
启动机器人串口通信
turtlebot3_lidar.launch
启动雷达 并且设置雷达数据的坐标系是"base_scan"
turtlebot3_slam.launch
有了一个新的发现就是slam方法可以用RTAB-Map替换！
turtlebot3_remote.launch
robot state publisher
感觉是在做turtlebot3和slam之间之间连接的工作， 是在启动turtlebot3的软件就是仿真和硬件就是串口之间的通信。
turtlebot3_gmapping.launch
设置数据的坐标系，
turtlebot3_navigation.launch
设置一些参数，启动turtlebot3，载入地图，启动amcl，启动move_base
amcl.launch
move_base.launch
