WOW!!!! (if it was on Discovery, I missed it :( ...argh)
Ok, so, there's a usefull use for a low resolution Compass Sensor !!!!!!

LOL, ok, I'll buy some 60 RCX's to implement that kind of navigations ;)
errrrrr.... well... one could use the ancient (lego) brick trail technic,
being dropped behind the bot. If the container of bricks is empty, the bot
get's back to it's home, gets some more bricks, follows the trail until the
end, and continues :> ...so there's an adaptable, removable (lock your
pets!!!), little-landmark + line-following technic, ehehehe
