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?

We plan on using one of the black "intake rollers" to feed the balls into the shooter, and use a ziptie roller in front to suck them into the small storage area that we will have. (max size is quite small, 12"x12"x9")
