首先请您自行依据线标提示将小强接线连接好，完整结构如下两图所示：
小强是属于Turtlebot机器人。它由底盘、主机、Kinect相机（通过USB连接主机）组成，没有显示屏。如果要通过显示器查看主机的Linux影像，则需要通过HDMI转VGA线另外连接台式电脑显示器。
本机ip地址：查询本机ip地址。
通过ssh远程连接，其中xxx.xxx.xxx.xxx是小强的IP
ssh xiaoqiang@xxx.xxx.xxx.xxx
在小强机器人上按“ctrl+alt+t”调出命令窗口：

xiaoqiang@xiaoqiang-desktop:~$ rostopic echo /system_monitor/report
imageStatus: True
odomStatus: True
orbStartStatus: False
orbInitStatus: False
orbScaleStatus: False
brightness: 0

其中 imageStatus 表示摄像头是否工作正常。odomStatus 表示底层驱动时候工作正常。Orb相关的三个变量是视觉导航相关的状态,可以不用管(如果对这方面感兴趣可以在论坛里进
行交流)。brightness 是摄像头的亮度,power 是当前电池的电压值,如果无法读取则是 0.
远程遥控：
通过 ssh 进行连接
ssh xiaoqiang@xxx.xxx.xxx.xxx
启动遥控程序
rosrun nav_test control.py
现在就可以通过方向键来控制小强的移动了。空格键是停止。Ctrl + C 退出程序。

1.配置小强网络

为什么一定要是Linux呢，因为ROS只有Linux版，所以必须是Linux，而且Linux是开源的系统，免费而且开源，可以改造，轻便，适合于工业制造，而且有很多的开源代码，当然很多开源代码是跨平台的，通过CMake也可以用于Windows、Mac、Android等。
为什么一定要将图像传输到服务器端，在客户端也可以处理啊，的确是这样，但是服务器端可以操纵小车的行走，这个是在客户端所不能完成的，所以这个控制是必须由服务器端完成的。
