Abstract

An apparatus for reconfiguring robot components in an environment that includes a robot terminal apparatus, including a plurality of internal components, and external components, interacting with the internal components, includes a situation monitoring unit for checking whether there has been a change in a situation of the robot terminal apparatus. Further, the apparatus includes a component availability analysis unit for determining at least one available component that belongs to the internal components or the external components; and a component search unit for searching for at least one component based on results of the determination of the component availability analysis unit. Furthermore, the apparatus includes a component dependency analysis unit for analyzing a dependency relationship between the component found by the component search unit and the component determined to be available by the component availability analysis unit; and a component reconfiguration unit for reconfiguring a connection relationship between the components.

Claims

1. An apparatus for reconfiguring robot components in an environment that includes a robot terminal apparatus, including a plurality of internal components, and external components, existing outside the robot terminal apparatus and interacting with the internal components, the apparatus comprising:

a situation monitoring unit for checking whether there has been a change in a situation of the robot terminal apparatus;

a component availability analysis unit for determining at least one component that belongs to the internal components or the external components and that is available in accordance with a change in the situation of the robot terminal apparatus based on results of the checking of the situation monitoring unit;

a component search unit for searching for at least one component based on results of the determination of the component availability analysis unit;

a component dependency analysis unit for analyzing a dependency relationship between the component found by the component search unit and the component determined to be available by the component availability analysis unit; and

a component reconfiguration unit for reconfiguring a connection relationship between the components based on the dependency relationship between the components analyzed by the component dependency analysis unit.

2. The apparatus of claim 1, wherein the component availability analysis unit determines the at least one available component that belongs to the internal components or the external components and that is available in accordance with the change in the situation of the robot terminal apparatus.

3. The apparatus of claim 1, wherein the component search unit searches for the at least one component available in accordance with the change in the situation of the robot terminal apparatus.

4. The apparatus of claim 1, further comprising a component information storage unit for storing information about the components, which can be searched by the component search unit for a specific component.

5. The apparatus of claim 4, wherein the specific component is the component available in accordance with the change in the situation.

6. The apparatus of claim 1, further comprising a component downloading unit for downloading at least one component that belongs to the components based on results of the analysis of the component dependency analysis unit and that is not present in the robot terminal apparatus.

7. The apparatus of claim 6, wherein the components that are based on the results of the analysis of the component dependency analysis unit are components that are analyzed as components which should be executed in the robot terminal apparatus.

8. The apparatus of claim 6, further comprising a component storage unit for storing the component that is downloaded by the component downloading unit.

9. The apparatus of claim 1, further comprising a component life span management unit for stopping execution of the components reconfigured by the component reconfiguration unit and the components analyzed by the component availability analysis unit, or for executing stopped components.

10. A method of reconfiguring robot components, comprising:

monitoring a current situation of a robot terminal apparatus;

if, as a result of the monitoring of the situation, it is determined that there has been a change in the situation of the robot terminal apparatus, determining whether there is at least one unavailable component by analyzing component availability;

if, as a result of the determination, it is determined that there is no unavailable component, searching for a component available in accordance with the change in the situation of the robot terminal apparatus;

analyzing a dependency relationship of the available component; and

if, as a result of the searching and the analysis, it is determined that there is a component in the robot terminal apparatus, reconfiguring the component and executing a component not being executed.

11. The method of claim 10, further comprising, if the determination reveals that there is at least one unavailable component, releasing a connection with the unavailable component.

12. The method of claim 11, wherein said releasing the connection with the unavailable component comprises stopping execution of the unavailable component.

13. The method of claim 10, further comprising, if it is determined that there is at least one component that is not present in the robot terminal apparatus as a result of said searching and analyzing, downloading the component.

14. The method of claim 10, wherein whether there has been a change in the situation of the robot terminal apparatus is determined when the robot terminal apparatus has moved from a location to another or a component device has been added.

15. The method of claim 10, wherein information about the available component used in the searching comprises one or more of a component ID (identification), a component name, a component address, a component location, a component function, and a component attribute.
