This omni wheel and motor kit is a full set of 4 high-quality omni wheels with matching motors with encoders and mounting screws. These wheels have small rollers around the circumference which are in a 45° angle to the turning direction so that the wheel can slide sidewise. A vehicle with 4 omni wheels is able to move in every direction without changing the orientation of the chassis.
