The Use of Frontal and Peripheral Perception in a Prey-Catching System

Abstract

The robotic implementation of a basic prey-catching system offers an incremental framework that can be employed to model social behaviors. Avoidance and preference for running next to walls is shown for a simulated prey. In order to chase and locate the prey; the simulated predator presents a switching of behaviors between wandering, tracking, and locating. Computer vision, action selection and reactive robotics act together in the proposed system to control both a simulated prey and predator. Distributed communication, over the TCP/IP protocol, facilitates running the controller of the prey in one computer and the one of the predator in another. Within this framework, experimentation was originally made using a robot simulator; afterwards two Khepera robots were employed. Some encouraging results support the development of a system of this kind.
