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.
A 1/2 inch hub is used to connect a wheel to the motor. This hub fits all Nexus Robot wheels.
The 4 inch (100mm) Nexus Robot double plate aluminium Omni wheels have rubber rollers mounted along its circumference to help avoid slipping. Each roller has two bearings which allow the wheel to move smoothly and easily in ANY direction.
Use these roll pins to fix sprockets to a shaft and keep them locked in place.
Waterproof ultrasonic distance sensor. This sensor can be used for collision detection in your project.
