Servo Motors

The catapult will be utilizing 3 servo motors to achieve what we want. Servo 1 will control the tension in the springs setting the tension point. Servo 2 will be potentiometer controlled and will control the bar that stops the catapult arm for controling launch distance of the object. Servo 3 will be a simple button controlled servo to hold the arm down while it is under tension from the springs, when the button is pushed the servo arm will rotate 90-degrees letting go of the catapult arm and launching the projectile.
