Not to toot my own horn, but two or three years ago, when we had the last non-autonomous period, we had a game based on soccerballs. We built a catapult powered by constant force springs (the springs made of coiled sheet metal) using 6 5lb springs, we got our robot to shoot soccer balls 99% effectively. The good thing about this was that our robot did not shoot at different velocities because of the change in our battery level.
