For the developmet of mental model of intell igent robot, in this paper we deal with a co gnitive modeling system based on the cogniti ve process of human being, using psychoanaly sis and two kinds of emotion theories artifi cial intelligence, neural network and fuzzy petri net. Based on the psychoanalysis of Fr eud, we graph the psychiatric structure named mind sketch by KNBN(Kohonen Network based on Belief Network).Within the mind sketch, emotion is used as the base for making relative data. It is based on the emotion theory of Plutchick and the cognitive emotion theory of Ortonyet al. To combine these emotional theories, a fuzzy Petri net algorithm has been proposed.
