Abstract
In this paper, we propose a patient robot whose feeling changes as varying time by making use of chaos orbit to create human's psychology and we develop a system for the effective injection training. For confirming the effectiveness of this patient robot, according to experiment with patient robot using by student nurses, we measure heartbeat of student nurses at four different experiment conditions and we get questionnaire concerning with injection training and patient robot. In addition, we propose visual servoing by making the patient robot do some motions like human. Visual servoing to 3D head pose has been performed by the motions of eyes, neck and waist of the patient robot to keep the human's front face in the center of input images in left and right eyes.
