This paper describes the design of new centralized acceleration-based controllers for the multi-task problem
of motion planning and control of a coordinated lead-carrier team fixed in a dual-formation within an
obstacle-ridden environment. A dφ− strategy, where d and φ are Euclidean measures with respect to the lead
robot, is developed to ensure virtual connectivity of the carrier robots to the lead robot. This connectivity,
built into the system itself, inherently ensures globally rigid formation between each lead-carrier pair of the
team. Moreover, a combination of target configuration, dφ− strategy, orientation consensus and avoidance
of end-effector of robots results in a second, locally rigid formation (not infinitesimally rigid). Therefore,
for the first time, a dual-formation control problem of a lead-carrier team of mobile manipulators is
considered. This and other kinodynamic constraints have been treated simultaneously via the overarching
Lyapunov-based control scheme, essentially a potential field method favored in the field of robotics.
The formulation of this new scheme, demonstrated effectively via computer simulations, is timely, given
that current proposed engineering solutions, allowing autonomous vehicles on public roads, include the
development of special lanes imbued with special sensors and wireless technologies.
