In this paper a mouth opening and closing training robot named as WY-5 (Waseda Yamanashi version 5) is analyzed in terms of stiffness characteristics. Basic models and a formulation are proposed in order to deduce the stiffness matrix as a function of the most important stiffness parameters of the WY-5 architecture. A numerical simulation is carried out as based on the proposed formulation. Experimental tests are carried out in order to validate the proposed model that can be used for design/control purposes in order to improve the performance of WY-5.
