1. A control apparatus of an autonomously navigating lawnmower driven by drive units while servicing a work area, comprising:
an information acquisition unit that acquires information regarding at least one of a region not planted with lawn and a region with lawn balding as information relating to a navigation-desired region where navigation is desired inside or outside of the work area;
a search unit that searches for a navigation route passing through the navigation-desired region from a current location of the lawnmower to a desired location based on the acquired information relating to the navigation-desired region so as to minimize lawn balding in other regions; and
a control unit that controls the lawnmower to run by driving the drive units in accordance with the navigation route searched by the search unit.
