IR Line tracking Sharp/robotigs/icons/login_key.png    alt  
2 pieces of QRB1134 by Fairchild can make a line following robot. It may also prevent your robot driving down the stairs. In the year 2004 this was state of the art but in the Arduino era the xx is a way better solution.

We also have the GP2D120 by Sharp which does about the same at a much greater range.
