Although it's an "old" book now by scientific standards, Valentino Brateiberg's Vehicles (MIT press I believe, still in print) contains a clear and accessible discussion of this topic, plus reference to the standard literature.

Judging from the lively discussions in an accompanying thread on line followers, it seems that following a single black line is far from being a trivial matter. It seems to me more natural to be keeping (...) (25 years ago, 17-Nov-99, to lugnet.robotics)

Change the constraint and it starts to become a little more trivial... we're just splitting the problem by focusing on both the mechanical and (...) (25 years ago, 17-Nov-99, to lugnet.robotics)
