i have to build a robot for my ECE class. wee need to make it run through an unknown maze. were using Interactive C, and wee can't have multithreading (sucks)...

Wee have our robot competition on friday, and i need to fine tune it so i can win the comp and save my grade.

heres some things that i could use some help with:

I need to make the wheels go faster, but without losing torque. wee are already using the motor at full power (no choice) and so the only option would be to change the gear ratio. how would i do this? wee have two gears right now (there is small, medium, and large) were using two medium sized wheels. one on the motor, one on the wheel.

i attached the code for the robot.

Only thing I can think of is reducing friction. Oiling the gears and bearings/bushings?

no, were using plastic gears. but i need to add more torque to the wheel. how do i do that with gear ratios?
