Using Python to Control Servo Motors

Servo motors can be used to make precise and quite repeatable motions. They can be controlled with the Raspberry Pi or add-on boards. We will be using them to build a pan and tilt mechanism—a head to position a sensor.

In this chapter, we will cover the following topics:

• What servo motors are and where you might see them in use
• How servo motors are positioned and how to position them with the Raspberry Pi
• What a pan and tilt mechanism is and how to build one with servo motors
• How to add this pan and tilt service to the robot object and test it
