Ahhh...

So it begins to make sense. Now the case you provided exists while the wheels are positioned tangentially along the circumfrence of a circle who's center is your 'instant center'.

So...

What is the result when the two wheels, as tangents, don't create a circle? Of course any two tangent lines determine a set of circles...and one point determines the radius; but what if the other tangent point doesn't lie on that circle? Namely, what if the 'instant center' isn't in line with the center of the 'bot? Wouldn't you get a lot of drag there? Or maybe you just don't move in a circular path...


...hmmmm
