MEXI: machine with emotionally eXtended intelligence

Abstract

This paper describes the robot head MEXI which is able to show artificial emotions by its facial expressions and speech output. The focus of this paper is on MEXIs software architecture. MEXI does not rely on a world model to control and plan its actions like usual goal based agents. Instead MEXI uses its internal state consisting of emotions and drives to control its behavior. Furthemaore we extended the behavior based programming paradigm originally developed by Arkin for robot navigation to support a multidimensional control architecture based on emotions and drives.
