The parallel maneuvering system includes a first coupler and a second coupler, which are slidably mounted with respect to one another, and which each include a pair of arms for eccentric pivotal attachment to a corresponding pair of wheel assemblies. The first and second couplers are mounted within a hollow chassis, and the wheel assemblies are mounted to the hollow chassis such that respective wheels thereof are mounted external to the hollow chassis, and respective eccentric crank arms thereof are mounted within the hollow chassis. At least one linear actuator may be provided for selectively driving sliding movement of the first coupler with respect to the second coupler.
