A complementarity problem formulation of the frictional grasping problem Original Research Article

The problem of secure grasping in the presence of unilateral contact and friction effects is formulated as a nonlinear complementarity problem (NCP). This approach, in comparison with other methods which involve piecewise linear approximations, is very natural and applicable. The proposed formulation covers isotropic and orthotropic friction conditions. Numerical examples which illustrate the developed method are included.
