Sorry. I've been working in the auto industry so long that I think "track width" and "wheel base" are part of everyone's household vocabulary.
Here are the simple definitions (assuming your robot has 4 wheels in the corners of an imaginary rectangle):
Track Width: Track width is the perpendicular distance between a line connecting the left side wheels and a line connecting the right side wheels (i.e., the left-to-right distance of your wheel footprint). Put another way: Coat your wheels with paint and drive it in a straight line. Your robot will make two paint lines on the ground (one from the left side wheels, and one from the right side wheels). The distance between the two lines is the track width.
Wheel Base: Wheel base is the perpendicular distance between a line connecting the front wheel contact points and a line connecting the rear wheel contact points. (i.e., the front-to-back distance of your wheel footprint).
I hope that helps.
