The name is Chiaphua okay.

Just curious did anyone ever think of using a worm drive system for their gearbox driving the wheels? It could pack a lot of reduction in a very small area. Also, I've seen in a white paper a gearbox using the drills motors, chiaphuas, and fisher price motors. I was wondering if any other teams use anything besides drills and chiaphuas to drive.

I had another really cool idea for a drivetrain. Have 2 motors drive a common central shaft. This shaft is input perpendicular into an axle with bevel gears driving a differential, much like the drive shaft and rear axle of a pickup. Have a giant servo or two control brakes on each side of the axle. When you want to go strait, no brakes. To turn left, pull the left brake. This would work somewhat like Jeep's VariLock axles in that each brake is controlled individually. There are no advantages to this kind of drivetrain that I could think of. There are actually many disadvantages: costly, time consuming to make, big, heavy etc etc etc. But it would still be really cool. Maybe a run at an award?
