Abstract
A wheel fastening system for a wheeled mobile robot includes a chassis, a motor, a wheel, a thrust bearing, a stud, and a screw. The chassis has a base and a cover. The cover covers the base. The motor is disposed in the chassis. The motor has a shaft. The wheel has a hub by which the wheel is centered on the shaft of the motor. The thrust bearing is an interference fit between the wheel and the chassis and provides axial support for the wheel. The stud passes through the hub of the wheel to couple to the shaft of the motor. The screw is coupled to the stud, and is clamped between the base and the cover of the chassis. The stud and the screw prevent the wheel from radially shifting relative to the shaft of the motor.
