Abstract

The paper presents a technical introduction to psychological theories of emotions. It highlights a usable ideaimplemented in a number of recently developed computational systems of emotions, and the hypothesis thatemotion can play the role of a scheduling variable in controlling autonomous robots. In the main part ofthis study, we outline our own computational system of emotion – xEmotion – designed as a key structuralelement in the developed target device, being an Intelligent System of Decision-making (ISD) for autonomousand robotic units.The ISD system has a cognitive architecture based on the principles of human psychology. The mainpurpose of building such a system is to prepare a framework for autonomous units used in system engineering(Kowalczuk and Czubenko, 2011; Czubenko et al., 2015). In particular, ISD is based on the concepts ofcognitivepsychology(in information processing) andmotivation theory, which includes the system ofneeds(for decision-making). The xEmotion subsystem, however, focuses on modeling an alternative approach based on emotion.The xEmotion implementation covers aspects of somatic, appraisal and evolutionary theories of emotions usingfuzzy sets.In this article, we also illustrate the core emotional behavior of the ISD system using simulation. Thefirst application is a user interface for identifying emotions and predicting human behavior. The second is aneSailor simulation, which illustrates the possible behavior of the xEmotion subsystem. The last is an xDriversimulation experiment, which is to prove the validity of the concept of using emotion-based systems, accordingto the SVC principle. In summary, we also discuss other possible applications of the xEmotion system.
