Abstract


In this paper we present a methodology for determining the optimal force distribution   in case of multiple manipulators system grasping an object. The force distribution problem is formulated in terms of a nonlinear programming problem under equality and inequality constraints. The friction constraints are transformed from non linear inequalities into a combination of linear equalities and linear inequalities. The original non linear constrained programming  problem is then transformed into a quadratic optimization problem. Some simulation results are given and the generalization of the approach to multiple manipulators system grasping an object is discussed.
