Abstract
This paper introduces a multi-dimensional emotional engine which is influenced by personality of robot. It is a novel approach to design an emotional model by comparison with conventional emotional model which used three-dimensional emotional space. It calculates most emotional elements and memorizes them for the next step of calculation of emotion. This means that robot does not respond to external stimuli directly. We have designed a personality based emotional model. It consists of five elements; reactive dynamics, internal dynamics, emotional dynamics, behavior dynamics, and personality. Personality is the most important element for making different emotions and behaviors of various kinds of robots. It is related to most calculations in the emotional model. If personality is changed, the emotional model makes different emotions and behaviors, although external stimuli and internal dynamics remain unchanged. We have used the intelligent service robot dasiaiRobi Qpsila which is used for children. We have tested the performance of the proposed emotional engine.
