The coordinated control algorithm for multiple mobile manipulators without force/torque sensors handling a single object in coordination controls individual mobile manipulators as if the grasping point has impedance dynamics by using the real manipulator’s dynamics. Mobile manipulators handle the object in coordination using the leader-follower control algorithm we propose, based on impedance dynamics. After discussing the effect of parameter error and how to reduce it, we confirm the proposed control algorithm’s feasibility in experiments using two mobile manipulators.
