Chapter 76 — Evolutionary Robotics

Discrimination of objects through sensory-motor coordination

A Khepera robot provided with infrared sensors is evolved for the ability to find and remain close to a cylindrical object randomly located in the environment. The discrimination of the two types of objects (walls and cylinders) is realized by exploiting the limit-cycle oscillatory behavio,r which is produced by the robot near the cylinder and which emerges from the robot/environmental interactions (i.e., by the interplay between the way in which the robot react to sensory stimuli and the perceptual consequences of the robot actions).
