The arm has positional control so we can set it to a position and it will stay there. This allows us to hit the ball on the stand. We've also got light sensors on the bottom so we can do it accuratly.

The pneumatic system at the base of the tower is to allow it to have 2 positions. We have one angled up and back a bit and another down at about 60 degrees. This allows us flexibility without the complexities of having to have the arm powered by a motor(which we did last year). The arm doesn't need to drop down since we have the wings which pop out the side and we need to protect our ball grabber.
