These 96mm diameter, goBILDA mecanum wheels are an excellent option for building a nimble chassis for smooth surfaces. Mecanum wheels provide maneuverability like no other wheel design. When used in a set of four, they allow omnidirectional movement. They give your robot the ability to move right, left, forward, backward, or at an oblique angle, while retaining the ability to rotate around the center of the chassis like a skid-steer chassis with conventional wheels.
These particular mecanums provide unparalleled performance for a number of reasons.
