A number of robotic tasks exist, such as manipulating heavy and oversized objects, where a single manipulator is not enough and multiple mobile manipulators need to be used. When uncertainty exists, a compliant control strategy is expected to be applied for such a tightly coordinated multiple mobile manipulator system. An adaptive impedance control law that enables adaptive updating of impedance parameters is developed in this work. The proposed method ensures that all closed-loop systems boundedly and asymptotically realize the desired adaptive impedance dynamics. Furthermore, to ensure the passivity of the adaptive impedance system, the impedance system of each mobile manipulator is interconnected with a virtual energy tank, and the update of the impedance system parameters is guided according to the level of the energy to ensure that the adaptive impedance system is passive, thus realizing the adaptive trade-off between compliance and operational accuracy. Finally, a simulation for four mobile manipulators collaborating to carry an unknown object is provided to validate the effectiveness of the proposed one.
