At lesser inequality I believe it will lift the lightest corner relative to the others, but if you have a low CoG it will take a lot of lift to effectively move the robot's CoG to the geometric center and equalize the weight carried by each wheel.

I was under the impression that if the mecanums were pneumatically actuated, you could tune the pressure so that the cylinders would have some give. Then the heavier wheels would compress the springs, and all four wheels would still have the same ground contact. Am I wrong?
