Mechanical systems for autonomic nervous system in robots

Summary form only given. This paper describes the correspondence of human´s autonomic nervous system and the hardware mechanisms. We implemented the autonomic nervous system hardware into the independent autonomous mobile robot, named WAMOEBA-2 (Waseda artificial mind on emotion base), which has been developed in this research for the realization of the emotional communication between humans and robots. WAMOEBA-2 has four kinds of hormone parameters using an original algorithm-the evaluation function for self-preservation. These parameters influence various parts such as the motor output and the sensor gain. As the results of these functions, WAMOEBA-2 can cope with its environment and express the emotional behaviors. Finally, we evaluate the experiments concerning the psychological impressions which WAMOEBA-2 gives to humans.
