Omni Wheels

Omni-Directional wheels roll forward like normal wheels, but slide sideways with almost no friction (no skidding during turns). Use these wheels to make your robot turn smoothly or build a holonomic drivetrain.

VEXpro Omni Wheels are manufactured from Glass-filled Nylon with high-traction rubber rollers. Compatible with VEXpro VersaHubs for driving with a sprocket or can be used with bearings for use on an axle.

These omni-wheels were designed from the ground up to give the smoothest ride possible. Our construction method, using a dual roller design, 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!

Omni 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.

Ships fully assembled.
