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
'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!)
