You've heard the saying in real estate: "Location, location, location".
Well, with a mecanum vehicle it's "Wheels, wheels, wheels".
If you don't have well-designed wheels nothing else matters. Well-designed wheels are very expensive. The rollers are crucial: they must have the proper contour, overlap, alignment, and mounting (bearings).
Secondary considerations are wheel mounting (high lateral stiffness) and closed-loop speed control.
