The problem with a mechanical limit switch is that it requires the switch to be depressed to change state, and that requires touching the walls. I would like to third?fourth? the suggestion of the maxbotix ultrasonic sensors. A proximity/range sensor is the one of the only ways, if not the only way to avoid walls.
