One of my bots uses a sensos to center the steer. It turns the wheels right or
left putting steering motor on for a while, and when it's time to center
the wheels back it uses a sensor to check the central position.
I also suggest you use a belt-driven steering arrangment to provide a sort of
friction in case your motor is still running when you reach the maximum turn
(especially useful during test phase not to destroy your bot at every test
run!)
You may look at some pictures at my site:
