Abstract
A Mecanum wheel having a circular plate with a plurality of peripheral flanges formed thereon, the flanges having tab portions bent at an angle of less than 90° from said plate; a roller being mounted to and cantilevering off of each of said tab portions such that the axis of rotation of each roller is at corresponding angle of less than 90° from said plate. In some cases, the angles are approximately the same, being approximately 45°. By cantilevering the rollers, more space is available for use by machines using this Mecanum wheel design.
