This paper introduces the functions and driving mechanism of a face robot, Buddy, which consists primarily of eyes, eyebrows, eyelids, and lips. Using these elements, which are driven with 13 step motors, Buddy can show various natural facial expressions and also lip-sync in a natural manner. In addition, Buddy can perform facetracking and make eye contact with humans, which is important for emotional interaction. To make such functions more realistic, we developed a reaction decision model which can make Buddy perform a different reaction according to emotional condition or personality. These interaction performances are successfully demonstrated by experiments and simulations.
