A partner and I made a wiffle ball shooter for our school's VEX class's game we are prepairing to play for. The shooter is modeled after team 498's shooter from Aim High. Used only one motor module and geared it up to a 1:9 gear ratio which is the perfect speed to launch the balls into the 12 inch tall goal. It averages out at about 10 out of every 12 balls.

Have you created some sort of guide in order to bend those two rounded (red-colored) lengths of metal into the curves? I would be afraid that during a match you are going to get bumped by another robot, bending those rails ever-so-slightly, messing up your trajectory. If you had a nice cardboard guide cut out in the right shape, you could just re-bend the metal after the match back to the original shape.
Super sweet 
What sort of other shooter designs did kids in your class come up with?

The class designs are just starting to take shape. This was the first working prototype as the game rules were just distributed in the last few days. Here's a short video of the prototype working:

I hope you have better success with it than our robot had at competition.
We learned, Gravity feeding = bad
Are you going to be putting a storage bin on the front that the balls come out of, or just drive to a ball and have it roll right in?
