Motor selection and control

In this section, we will discuss the various motor options available to build a robot. For a typical desktop robot, the various motor options include the following:

Direct Current (DC) motors
Stepper motors
Servo motors

Let's discuss the applications of these motors.

DC motors

DC motors are ideal for wheeled robots. The following figure shows the DC motors used to drive the wheels of our robot. DC motors are widely used in toys because of their low cost and their small size. The DC motors used in our robot come with an in-built gearbox to reduce the revolutions per minute (rpm) and make it suitable for a wheeled robot.

DC motors are typically operated using an H-bridge circuit. This enables the speed and direction of travel to be controlled.

Stepper motors

Stepper motors are ideal for positioning applications. For example, stepper motors can be...
