The work described in this paper addresses the problem of determination of the appropriate distribution of forces between the fingers of a multifingered gripper grasping an object. The finger-object interactions are modeled as point contacts. The system is statically indeterminate and an optimal solution for the this problem is desired for force control. A fast and efficient method for computing the grasping forces is presented. Some simple grasps are used to evaluate the proposed algorithms. © 1991 ACADEMIC PRESS, INC.

A deep symmetry between serial chain manipulators and fully parallel systems such as the Stewart platform is demonstrated. This symmetry is shown to be a result of the well-known duality of motion screw axes and wrenches. The appearance of the inverse
