Agreed, a navigating robot would be far more effective, random just
won't
cut it (pun intended) ;-) Apart from the grass sensor idea I've
mentioned
from the Radio-Electronis article (which I am getting from the city
library
for background information), It may be possible to create a colour
sensor
that was responsive to the rough colour of grass. This is not as far

as it sounds, there are SMD chip colour sensors that I have heard of.
Green
of course like blue is a difficult colour to sense, but by using filters
it might be possible to eliminate the need for a boundary wire type
system.
