I don't have the Flynn book with me currently, but I coulda sworn that I read about the Rug Warrior (or some other robot) "wall following behavior". I thought that this was accomplished by IR obstacle detectors. I was also under the impresion that it is capable of detecting obstacles a little further that a few mm's (maybe a couple of inches). Did I read it wrong???
