Abstract
A direct human-robot communication system based on natural language (NL) and cognitive graphics (CG) as a part of a new hierarchical structure of an AI control system of a mobile robot for service use (MRSU) is developed. The software of the simulation system for direct human-robot communication and MRSU behavior based on NL and CG is described. The NL and CG are used for description and representation of possible external worlds in the robot artificial life. This system allows us to evaluate the control algorithms of real time robot behavior and to reduce difficulties connected with such troubles as robot collisions with real objects and robot hardware damage. The mathematical background of direct NL human-robot communication and robot behavior simulation system is knowledge engineering based on spatio-temporal and action logics, default reasoning, cognitive graphics and soft computing. The main concepts, structure, conceptual model of the simulation system for description of the artificial life of the MRSU are discussed. A simulation example and real experimental results are described.
