Does not have to boil... 140' is enough...

A professor that's in charge of a robotics class here at University of Florida
was telling his microprocessor apps. class how they've conducted an experiment
with a cleaner-type robot. They put an LED on top of it, and let it run overnight
in a room with some commonplace obstacles while having a camera with an open
shutter sitting on the ceiling all night. So, a robot with some kind of preset
pattern programmed into it did worst in covering the room than a robot that just
had random response to obstacle avoidance.
