I'm not really sure how we would do this though because I'm not on mechincal, but I'm hoping we succeed. Our chains broke in our final matches in Atlanta.
If your "chains broke" in several matches, going chainless (unless you only have four wheels, each direct driven) via gears/belts will only make the problem worse. Gear and belts need higher tolerances than [35-pitch] roller chain does.

If your chains broke, it's probably because they were improperly tensioned or misaligned. Look at solving these problems before you write off chain and attempt something else. If you don't solve the root causes behind your chain failures, the same issues will affect whatever other drive train design you implement.
