Re: Mecanum drive

The reason that the side-to-side motion is slower than front-to-back (for equal applied voltage) is that the rollers must spin for side-to-side motion, whereas they do not spin for pure front-to-back motion. The friction in the roller's bearings cause the speed to slow down.

High quality mecanum wheels with properly design bearings for the rollers will minimize this effect, but they would be quite expensive.
