Mecanum Wheels

Mecanum wheels allow savvy robot designers to create drivetrains capable of moving in any direction using a standard chassis shape. Simply power each wheel with a different motor and change the directions the wheels spin to get your robot to move in different directions!

Mecanum wheel assembly hardware is separate from sprocket mounting hardware. Sprockets are screwed into captive 8-32 standoffs. This allows for easy removal and replacement of sprockets without disassembling the entire wheel. No more worrying about your whole wheel falling apart just because you wanted to remove the sprocket.

These mecanum wheels were designed from the ground up to give the smoothest ride possible. Our construction method allows for a constant contact patch with a narrow profile. Each roller is tailored for the individual wheel diameter, and provides the correct, constant radius. We don't share rollers between wheel types -- these wheels aren't "almost round" -- they're actually round! This smooth-ride provides higher efficiency and reduces wasted power. This is especially important in mecanum drivetrains to provide smooth holonomic motion without high motor current draw.

VEXpro Mecanum Wheels are manufactured from Glass-filled Nylon, with ABS-PC roller mounts and rubber rollers.

6" & 8" Wheels ship fully assembled. 4" Wheels require assembly.

Note: We have identified an issue with the 4" Mecanum Wheels that may affect your performance. Please see the Mecanum Wheel Replacement Roller Kits page for more information.
