Abstract: This paper obtains the motion scopes of eyes,eyebrows,mouth,and lower jaw of human faces by analyzing their motion in typical facial expressions.Motion transmission relation between the face mechanism and the facial expressions is set up,and a three-dimensional structure model of a humanoid robot face is designed with AutoCAD and 3DS MAX.The parameterized control of a three-dimensional simulation is performed by MAXScript program,and the 3D simulations of several typical facial expressions are obtained finally.
