Our team has used magnet-sensors many times in the past. These sensors work two ways. Either you can glue magnets on a rotating surface and read them as they go by (like a big LP record).
Or you can actually sense the teeth of a sprocket - without any sort of preparation - provided of course that the sprocket is made of steel.
These sensors are a lot more durable than potentiometers since they have no physical coupling with the robot's moving parts.
We have used them in 2005 and 2007. However I think we had to make custom circuit boards for them.
