this could work but what if the robot turned and started going the wrong direction back towards the start???? it only follows the walls which could lead the robot back to the start not the finish -
anyrobot we do is basically going to be folllowing the wall though and it would have to go all the way to the end to start going back to the beginning

While Roomba is cleaning, it avoids steps (or any other kind of drop-off) using four infrared sensors on the front underside of the unit. These cliff sensors constantly send out infrared signals, and Roomba expects them to immediately bounce back. If it's approaching a cliff, the signals all of a sudden get lost. This is how Roomba knows to head the other way

this is how the roomba detects cliffs

Roomba can clean for about two hours on a single charge. If you have the self-charger, Roomba will return and connect to the charger all by itself when the battery power is low (the self-charger is sold as an add-on to the Roomba base model but comes included on most of the higher Discovery models). It accomplishes this using the infrared receiver on its front bumper. When the battery power gets low, the vacuum starts looking for the infrared signal emitted by the charger. Once it finds it, Roomba follows the signal and docks itself to the charger. Some robotic vacuums with this self-charging feature will head back out to resume cleaning once they're fully recharged

Adding a vertical ultrasonic sensor to ClareBot allows the robot to go around an arena without touching the walls

shows how to build a simple wall following robot

Although this is an older version, the placement of the Ultra sonic sensor is a good thought

interesting how it uses the wall following and the spiral, nice demonstration

this demonstrates how although it does the cleaning randomly it almost hits every spot eventually
