Light sensor with a magnifier? :-)
I tried using the differential gear to "remember" the initial heading of my
robot, and painfully discovered that the result would drift off after many
turns. Now I think compass is the way to go. (I wonder how Simen solves the
drifting problem in his Vector Rover.)
The type that comes with a ball suspended in liquid may be a better choice
because you don't have to level it too carefully.
