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 with ball bearings for smooth operation and higher load capacity. These are higher quality wheels than our 4" Mecanum Wheels with Plastic Sleeve Bearings.
Several wheel hub options are available for you to select from below.
An 8mm Hub used to connect a wheel to the motor. This hub fits all Nexus robot wheels.
A 6mm Hub used to connect a wheel to the motor. This hub fits all Nexus Robot wheels.
This is a prebuilt version of TP-251-003, our programmable triangular omni wheel vectoring robot. It can vector in any direction and is great for indoor robotics. An Arduino Mega and encoders allow for this to be an autonomous robot.
