I was looking at that tank. Sounds about ideal for what I am
after - really want something "slow" and torque-y. I suspect you
can steer it quite nicely using variable control on the motors.
Take off the turret, and have a nice flat platform for electronics.
COuld use the turret motor for panning a small CCD cam - or more
likely a light sensor for homing/recharge.
Since this will be autonomous, I already thought about having
a chain of lights around the house, flashing at different
frequencies - slower=farther from homebase - to help it find its
way back home.
In your case, you might want to mount a laser or acetylene cannon
ball launcher in the cannon tube. I figure I could mount a piezo
and use some squawks to scare the neighbor's cat - not hard to do.
[after the snow here melts, it can patrol the back yard and keep
the cat from chasing my pet squirrels - hmmm, pattern recognition].
