I think I failed to express myself clearly. By center of rotation, I meant that point on the bot where it thinks its center is, the point that a and b are based on in the equation for one wheel's speed, "|vw4 | = vty + vtx + ω(a + b)" (from strafing.pdf, page 19/35). I'm guessing that the controls would still come out incorrect, because of the uneven pressure on the wheels, but I thought I should make sure we were speaking the same english.
