See?! the discussion has started already.
My problem is that I'm definitely not up to state of the art in mechanics.
I think that's my bias. As a computer scientist I always think I can solve
the sensor/mapping/etc problems if I could just get the platform together.
Where can I learn about servicable motor, gears, drivetrains, etc?

Excellent! Are they on the web? Will check just as soon as I finish this
message....
Any suggestions for drive motors? Preferably a pair that I could mount
on a platform and directly attach lawn mower wheels to?

Even better. I think I'll be picking up one soon...

I thought those were more difficult because the drive motors are then
not on the center axis, making it difficult to perform maneuvers such as
spinning on place to turn and having precise control of the nose of the
vehicle. That's why I thought Ross was looking at a steerable rack on
the opposite end of the machine.
I cliam ignorance. Please feel free to enlighten me on the subject.
