That's my desire also. In a later post Raymond voices a concern about
theft. A loud siren could be fitted under the body that would sound if
the robot was lifted without an access code being entered, like the
solar mower. The siren could also be useful for alerting us to problems
with the robot.

Yep. I believe that is fully achievable, especially if we don't try to
keep an explicit map onboard (I'm not against explicit maps, but there
is not one real world example that works).

Yep, "The world is it's own best model" Jon Connell.

Fine, but we need to determine what low speed is.

Oh, I thought we could have Motorhead samples playing through a speaker

If it can be achieved I am quite happy with this, my only criteria is
that it cut effectively.

I'd put that more as an option,we need to accurately determine the
current requirements first.

We'll see. I'm not opposed to the HC11, it's a great chip, but I'm not
certain that incorporating all functions into a single chip are the best
way to deal with a real world robot.
