Proposal of a Masticatory Robot for Analysis of Jaw Movements

Abstract

In this paper, a life-sized jaw mechanism is proposed on the basis of biological masticatory structure. Its actual parameters are defined in Solidworks according to human masticatory systems, the trajectory and position error of masticatory robot is performed via ADAMS and Matlab. The simulation results have shown that the robotic jaw is able to reproduce the human behavior. However, because the mechanism is a highly coupled and nonlinear system, the position error cannot be eliminated completely, and more sophisticated control system is required in future study.
