Using a motor controller to control the speed of your platform
The first step to make the platform mobile is adding a motor controller. This allows us to control the speed of each wheel (or track) independently.

Before you get started, let's spend some time understanding the basics of the motor control. Whether you chose the two-wheeled mobile platform or the tracked platform, the basic movement control is the same. The unit moves by engaging the motors. If the desired direction is straight, the motors run at the same speed. If you want to turn the unit, the motors run at different speeds. The unit can turn in a circle if you run one motor forward and one backwards.
DC motors are fairly straightforward devices. The speed and direction of the motor is controlled by the magnitude and polarity of the voltage applied to its terminals. The higher the voltage, the faster the motor will turn. If you reverse the polarity of the voltage, you can reverse the direction the motor is...
