In all honesty, that's quite impressive. Could you shed any light on how you think this occurred? We ran the same gearbox, and (luckily I guess?) we only stripped the gears in the output stage.

It's only an assumption - I may be right or wrong:
The failing gearbox was the right one. Our robot design was not 100 precent perfect so if the driver was trying to cross the ramparts a little bit to the right, the robot will stuck and will probably get a strong counterforce as shown in this video.

A better assumption can be that the torqe transferd from the wheels was too high (8" wheels with 9.52:1 gearbox reduction).

Our lesson is that we should have replaced the small aluminium gear with steel gear.
