Differential?

Drifting sounds like a good way to completely destroy FIRST's carpets...

We've used a software differential for the last few years. Usually with encoders. Though last season we got one working using only a gyro.

Works well enough in either case. You don't even need to do the proper trig - all you want to do is reduce the slip on the inside wheel to an acceptable level.
