Development of 3 DOF jaw robot WJ-2 as a human's mastication simulator

Abstract

The purpose of this study is to establish a dynamic, quantitative engineering model for the mandible movement in human's mastication by reproducing this movement using a mechanical model and to define the mandible movement controlling mechanism from the viewpoint of engineering. To realize this purpose, WJ-2 (Waseda Jaw-2), a 3 degrees of freedom mastication robot, was developed. A description of the mastication robot WJ-2 with reference to human's actual mandible movement is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
