In a particular embodiment, a method includes receiving a communication from a source. The logic elements may include an RSFQ inverter and an RSFQ T flip-flop. An auxiliary control link is activatable to electrically connect the first brake component and the second brake component when a failure occurs in one of the first control network or the second control network, the auxiliary control link adapted to transmit the control signals between the first brake component and the second brake component when the failure occurs. The end effector is adapted to maneuver through a larger radius of curvature in the second movable position than in the first fixed position. In addition the present invention contemplates management of vehicle maintenance and goods such as groceries, toys, or books.
