The further the joystick is moved in one direction, the faster the motor will spin. When the
joystick is at rest, the motors do not receive any signal to move.

The Controller also has 4 pairs of buttons labeled E, F, R and L. These buttons
turn the motors on at full speed in one direction. Each button pair controls the
clockwise and counterclockwise direction of the motor.
See the Driver Control Program for a mapping of the joysticks and buttons to the
ports on the Robot Brain, when using the built-in Drive Control program.
