Modeling and simulation of masticatory robot

To design a masticatory robot with accurate reproduction of jaw movement for a range of applications, such as dental training, jaw simulation, food texture analysis and speech therapy, this paper presents a mechanism model with fuzzy-PID control and simulates the model in Matlab/Simulink. The mechanism model of masticatory robot is founded according to the biological structure of masticatory system by SimMechanics. The fuzzy-PID controller is designed via Fuzzy Logic Toolbox to control the masticatory mechanism. The simulation results have showed that the movements of masticatory robot are similar to jaw movements.
