We wouldn't _have_ to detect grass height at all, necessarily.
MowBot would cover the entire area.

There are obstacles that Mowbot must be able to deal with
to be useful (what I called priority 2)
Holes, ditches, Immovable objects
It must also recognize 'no-traverse' area's:
neighbors yard, garden, flower bed, steep bank.
----------------------------------------------------------
There is another 'map attribute' that I hadn't thought of
before.
'Traversal allowed - but no mowing'
These areas might be a gravel driveway that Mowbot could
traverse to get to other mowable areas, but should disable
mowing apparatus until it gets to the other side.
----------------------------------------------------------
Many of these 'map attributes' are impossible for Mowbot
to discover on its own. They depend on things like
land ownership, personal tolerances (how much 'buffer'
do *I* want between mowbot and my prize flowers/car/etc.)
and personal interpretation, (Those aren't "weeds",
they're "Herbs"... DON'T mow them!)
