Summary
In this chapter, you saw how to set up the Raspberry Pi Camera module. You then used it to see what your robot sees—the robot's view of the world.
You got the robot to display its camera as a web app on a phone or desktop, and then used the camera to drive smart color- and face-tracking behaviors. I've suggested ways the behaviors could be enhanced and hopefully given you a taste of what computer vision can do.
In the next chapter, we will extend our object-tracking visual processing to follow lines with the camera, seeing further ways to use the camera.
