Apparatus and method for expressing emotions in intelligent robot by using state information

Abstract

An apparatus and method for expressing emotions in an intelligent robot. In the apparatus, a plurality of different sensors sense information about internal/external stimuli. A state information collector processes the detected information about the internal/external stimuli in a hierarchical structure to collect external state information. An emotion motive determiner determines an emotion need motive on the basis of the external state information and the degree of a change in an emotion need parameter corresponding to internal state information. An emotion state manager extracts available means information for satisfaction of the generated emotion needs motive and state information corresponding to the available means information. An emotion generator generates emotion information on the basis of a feature value of the extracted state information. An action determiner determines action information for satisfaction of the emotion need motive on the basis of the extracted state information and the generated emotion information. An action expresser expresses an action corresponding to the action information through a corresponding actuator on the basis of the determined action information.
