Summary
In this chapter, you have learned about servo motors, how to control them with your motor controller, and how they work. You've built a pan and tilt mechanism with them and added code to the Robot object to work with that mechanism. Finally, you've demonstrated all of the parts with the circling behavior.
You will be able to use the code you've seen to control other servo motor systems, such as robot arms. The animation style techniques can be useful for smooth movement and circular motions. I used a system a little like this when controlling the 18 motors in SpiderBot's legs.
You've seen how to use a servo with a sensor on a head to make some kind of map of the world and related it to the LIDAR systems used on bigger and more expensive robots.
In the next chapter, we will look at another way to map and observe the world with encoders. These sensors will detect wheels turning on our robot to determine how our robot is moving.
