Abstract : "Formation control is a potential advanced technology for aircrafts, spacecrafts and space robots. This
paper, for the first time, studies several methods of passive and semi-active Remote Center Compliance (RCC)
in order to examine their effects on formation control of a group of Wheeled Mobile Robots (WMRs) for object
manipulation during space/terrestrial explorations. To this end, first, the dynamics model of the constrained nonholonomic
robots, object and RCC system have been derived precisely. A leader-follower control strategy is then
utilized for trajectory tracking of the desired path by the cooperative robots. Finally, the passive and semi active
RCC are optimized to make the formation robust in the presence of significant disturbances. The results obtained
reveal that the semi-active RCC system, combined with a PID controller, reduces the effect of the disturbances
experienced as compared to the other passive RCC modules."
