10 | * The IntakeArm consists of two rollers that are controlled by one motor, with |
11 | * a potentiometer on it. | |

13 | * The motor controls the rollers, making them roll forwards and backwards. The |
14 | * Intake rollers are on the back of the robot. As the rollers run, they intake | |
15 | * the ball. | |
