Re: pic: Omni Design Trial
Though incredibly versatile, the standard Mecanum wheel has an unfortunate side effect which reduces its effeciency considerably. Its wide range of mobility is due to the fact that the peripheral rollers translate a portion of the motor force into a force perpendicular or at an angle to that produced by the motor. This means that are large portion of the force in one direction is lost through the translation into a resulting force by the rollers.
... Losses of effeciency when traveling in a straight line are due to energy lost in a direction normal to that of travel through the peripheral rollers which bleed off available energy as they rotate. From http://www.araa.asn.au/acra/acra2002...eter-Tlale.pdf
