A robot mower with preset patterns which revolve around a master
remote-controlled device.
The master device is a big-wheeled all-terain-type vehicle, and
the
satellite is a mower with preset patterns.
The types of patterns and interface would be determined by Very
Clever People and
would be very slick and cool.
The mower would be very slow and electric, and would dock
automatically when low.
And it would have a handle and would be manually programmable
for specific applications in tight places in the yard, if the anchor
was
in a specific (and easily found) location.
You would set it each evening, fiddle with it and mess with it, and
never push a mower again.
