Abstract
Expression of emotions by robots is receiving more and more attention in robotics. Much research in the field uses specifically devised robots, often humanoids, capable of providing facial expressions. Much less research focuses on non-anthropomorphic robot, and even in these cases, the robot movements are usually hand-designed, or obtained by transformation of human movement. In this paper we show that even a simple Central Pattern Generator, with randomly set parameters, was able to produce recognizable emotions on a non-anthropomorphic and non-zoomorphic robot.
