Coordinated motion control of multiple robots manipulating a large object

Abstract

In this paper, we discuss a problem relating to the force/moment transformation for the handling a large object by multiple robots in coordination. Three control algorithms, based on impedance control of each manipulator, are then proposed so as to lessen the effect of the transformation. The algorithms are implemented in dual manipulator system, which consists of two industrial robots. Experimental results illustrate the validity of the proposed control algorithms.
