A hybrid system using piezoelectric brake (PB), ultrasonic motor(USM) and electromagnetic motor(EMM), which have different characteristics, successfully achieved to represent the realistic feeling with wide ranges of force. The combination and control method of the actuators were examined by virtual models produced in personal computer. The feelings of reaction and roughness were able to be represented enough with friction control by using only PB. The EMM and USM were suitable to represent an elastic force and repulsive force, respectively, which needed sudden acceleration. Moreover, the hybrid system extended to two-degree-of-freedom motion enabled a two-dimensional operation. The testers' evaluation of the hybrid system was high. Hence, the objective of this study was almost achieved.
