Modeling of the emotional model with friendship for familiarity of robot

This paper deals with the emotional model of the software-robot. The software-robot requires several capabilities such as sensing, perceiving, acting, communicating, surviving and so on. There are already many studies about the emotional model like KISMET, AIBO. Though many emotional models are implemented, their human response architectures are invariant as time passes. Conventional emotional models make a robot like and obey a human during robot operation. This is natural for robots which are used in industrial, service and military areas but for pet robots this property lets robot look like real robots not real pets. Actually, a robot's emotional model is studied to implement robot intelligence more easily but emotion expression has to be exaggerated in a pet robot to make it interesting to humans. Pet robots must show dynamical emotion variations. The emotional model with the modified friendship is studied in this paper to overcome the conventional emotional model's limits to apply to pet robots. Friendship is distinguished as positive, negative and static schemes and an emotional model with the modified friendship is implemented and simulated on a software-robot.
