Lots of Wheels and F = u x N

Hi all you gearheads out there,
I'm an RF electronics guy ... so all this traction stuff is just another exercise in vector analysis to me. My old physics classes told me that F = u x N, or propulsion force equals the coefficient of friction times the force normal to the surface.

So, why does everyone want to add 356,215,492 wheels to the robot???? When you add another wheel, the force is distributed so your N is reduced by 50% .... net result is no increase in propulsion force. I can see for real trucks that they need to distribute the load on roads and may be happier on soft surfaces, but why are more wheels better for us???

Your words of wisdom to enlighten my meager knowledge will be accepted as a ray of light in my void of ignorant darkness.
Thanx, Ernie P
