Modeling equations are obtained using a constrained Lagrangian Formulation, resulting in a nonlinear integro-differential system of equations with a fourth order Partial Differential Equation (PDE). This system of equations is subject to boundary, initial and consistent conditions in order to obtain the system response and observe the elastic deformation of the flexible link. Measurements of the elastic deformation at the coupler link are presented, and the proposed model is experimentally validated.
