robots and automation; swarm behaviour; simulation model


We describe simple simulation models of collective swarm behaviour of simple robots. We have experimented with mixed avoidance and seeking behaviour using tri wheeled robots using simple ultrasonic proximity sensors. Our model assumes a radial distance of attraction or re pulsion and supports multiple species in the swarm based on sensor recognition protocols. We describe the surpris ing success of our model in predicting the gross and sta tistical behaviour of our swarm and discuss limitations and potential improvements to the model. We also discuss scal ing experiments to large swarm sizes. We also speculate on thermal physics model analogies to the swarm and how these can be parameterised.
