The right (or left (-: ) -hand rule seems to be simple but not the most
efficient. That's why I included the light beacon. Providing you have
the right beacon detector (let's build one!), and you don't know which
direction is the best, you can balance your choice with the beacon
detector's information. There should be two tasks : one which gives the
best direction to follow with the wall-sensors information, and one
which gives the best direction to find the light beacon. With some kind
of fuzy logic (two restraints which gives one final solution), it should
be possible for another task to optimize the robot travel, and make it
shorter...
