Robots design?

I can't think of a way to shoot the balls. The most effective way to shoot in Aim High was feeding a ball through 2 pairs of spinning wheels but with these orbit balls I see a number of problems. It would be difficult to apply pressure, as they deform (and break) easily. Furthermore they do not have a uniform surface, to shots will be inconsistent. And, the fabric covering will decrease traction (especially compared to the rubbery foam in the nerf balls). I really can't imagine an effective shooter based on a softball pitcher model.The best I can think of is a catapult style shooter that I remember one team had in 2006.
