I think what Chris is saying is that the axle would not hit the bump. Many other parts would hit the bump, and your argument is well founded but the axle itself will not hit, as it is within the perimeter of the mecanum wheel. Assuming of course that a) this is a *standard* mecanum setup b) the robot is attempting to drive straight on to the bump.
