The purpose of this research is to develop the design method that can design various types of MDOF Ultrasonic Motors, resolving problems of conventional designing method. We decided to adopt the genetic algorithm considering the features of designing a MDOF Ultrasonic Motor .The decision variable are the shape of the vibrator and the vibration modes to drive it. We set evaluation functions considering designing conditions of a MDOF Ultrasonic Motor. We confirmed that the plate type MDOF Ultrasonic Motor designed by this designing method has ability to realize 3-degree-of-freedom movement that is more efficient than the conventional one. Therefore we showed the possibility that this designing method is useful for designing of any types of MDOF Ultrasonic Motor.
