In the forward direction for example, mecanum is the equivalent of 4 motors driving 4 wheels with the rollers locked, if the vehicle is not traction-limited.

If the vehicle is traction-limited, then mecanum is 41% more force than two motors driving two wheels with the rollers locked.


Not to start an argument but the white paper actually confirms what I was saying. In fact, it states in the body that "Therefore, assuming no roller bearing friction, the “pushing force” (and speed) of the vehicle is the same in the fore/aft and sideways directions." So I don't see how you got the 41% unless you are including friction from the bolt/axle but I would be happy to hear how you reached these conclusions.
