Were this robot code in a general sense, I would feel good
in quenching such thirst. But this is robot code of the
highly specialized sort, good for doing one thing, and it will
never mix drinks, nor fetch your newspaper, nor find your
pipe. It can't even play music by itself.
This robot knows how to follow an edge, if mathematically
defined to close enough tolerance. Definitely not cutting
edge stuff. Now if we ported Perl to the mindstorms, maybe
tacking on a few i960 coprocessors, that'd be something...
