We propose a control algorithm for multiple manipulators handling flexible metal and discuss how to deform and manipulate sheet metal. We use a finite element method to derive the relationship between static deformation of sheet metal and bending and twisting moments exerted on it. We design a control algorithm to control deformation using internal force applied to the sheet. Experimental results obtained from two industrial robots verify the proposed control system’s validity.
