Abstract

This paper presents a cognitive model—the Sensory Motor System (SMS)—for an action execution process, as a new module of the LIDA systems-level cognitive model. Action execution refers to a situation in which a software agent or robot executes a selected goal-directed action in the real world so as to output pertinent movement. Action execution requires transforming a selected goal-directed action into lower-level executable actions, and executing them. A sensorimotor system derived from the subsumption architecture has been implemented into the SMS; and several cognitive neuroscience hypotheses have been incorporated as well, including the two visual systems and others. A computational SMS has been created inside a LIDA-based software agent in Webots to model the execution of a grip action. The grip’s design is inspired by the arm controller of the robot Herbert and the current study of human’s action execution. Simulated results are compared to human performance.
