My team burned out a Denso on the regolith last year with a 1:2 reduction, and I shudder to think what would happen on carpet with more friction, any more gearing down for torque and it would have turned too slow.
We are using window motors for our steering. I am not so sure about the gear ratio though. And we will change our wheels to have less friction, since it seems like motors are getting a lot of stress from it (one of them was HOT and it stopped functioning due to high temperature)
