Let's say you have a rectangular robot at max dimensions, with the wheels (or treads) a little bit inside the max. It looks like this:

That's the wheelbase as seen from the top. As long as you keep your CG above that area, you won't tip. As soon as the CG goes outside that area, you've got a split second to get it back before the big crash. If you have treads, you'll still have the same area.

Erich - Don't forget to remind your audience that inertia exists, and that it makes a moving robot do things that a stationary robot would not (like tip over even if the CoG is within its wheelbase)...
