Basically, when the ball hits the top of the lift, it is put in contact with the lower shooter wheel, which than shoots it along a track (thin spring loaded lexan) and through the shooter. During the design phase we struggled a lot with how to be able to change the angle, while having a moving adaptable track for the ball the follow. This was our solution.
It can be seen in the teaser video that is posted on our website here

It was a very fun season, and I'm very proud of team 229 and will miss it a lot upon graduation this May.
