The 4 inch (100mm) aluminum Mecanum wheel is comprised of a series of rollers, mounted so that their axis of rotation is 45 to the axis of the main wheel. As the wheels rotate in sync, the vehicle moves forward or in reverse normally, but by spinning pairs of wheels in opposite directions, the rollers enable sideways movement. Put it all together and you can move forward, backward, laterally, diagonally, or spin in a circle. Also included are twelve extra bolts (60 mm long) for bolting on the 6mm Nexus aluminum wheel hub or the 8mm Nexus aluminum wheel hub.
Each roller is supported by plastic sleeve bearing. These wheels will not support as much weight as our other 4" Mecanum Wheels with Ball Bearings.
Several wheel hub options are available for you to select from below.
This is a direct drive 4WD base robot kit that uses Nexus mecanum wheels and hubs. It's a great robot platform for indoor robotics. It can vector in any direction.
