Robot device, Behavior control method thereof, and program

摘要

In a robot device, an action selecting/control system ( 100 ) includes a plurality of elementary action modules each of which outputs an action when selected, an activation level calculation unit ( 120 ) to calculate an activation level AL of each elementary action on the basis of information from an internal-state manager ( 91 ) and external-stimulus recognition unit ( 80 ) and with reference to a data base, and an action selector ( 130 ) to select an elementary action whose activation level AL is highest as an action to be implemented. Each action is associated with a predetermined internal state and external stimulus. The activation level calculation unit ( 120 ) calculates an activation level AL of each action on the basis of a predicted satisfaction0level variation based on the level of an instinct for an action corresponding to an input internal state and a predicted internal-state variation predictable based on an input external stimulus.
