Motivation System for Virtual Creatures: Actions Driven by Needs

One of the biggest challenges in the development of virtual creatures is provide them with mechanisms that allow them to generate behaviors autonomously. Therefore we think it is possible to use agent architectures to endow those virtual entities, so to speak, with architectures that can serve as the brain for these entities. In this paper we present an agent architecture that takes as inspiration for its creation, biological and psychological theories that consider that needs are the cause of behaviors in living beings. To test the model, a predator-prey scenario was selected. In this virtual world, the creatures do not have an established purpose, therefore their survival completely depends on the satisfaction of their needs. As a result of this work we obtained autonomous entities that can survive in a predator-prey environment.
