Abstract
This paper proposes a robot which understands human satisfaction and takes adaptive behavior. The proposed robot has a theory of mind that estimates human mental state on satisfaction which is evaluated by the satisfaction measurement system based on electroencephalogram measurement. A physical robot named “adaptive behavioral companion robot with a theory of mind based on human satisfaction (ACM) ” is developed with emphasis on psychological interaction between autonomous robots and humans. ACOM has such unique functions as determining adaptive behavior to human based on learning which uses increase rate of satisfaction as the reward, and expressing emotions based on the reward which is given by how much human is satisfied by the adaptive behavior. Psychological impression of ACOM toward the human is examined through the interactive experiment between ACOM and human, showing the possibility of a robot with a mind from both subjective and objective evaluations.
