Abstract: Robotic collectives are used for the efficient achievement of complex tasks. There is a
significant increase in the interest for emergent, collaborative robotics as a viable alternative to the
more centralized classic approach as the dimensions, energy consumption and especially price are
becoming required constraints. This paper describes a nature inspired algorithm intended for the
movement and communication of such robotic collectives. As a case study, the implementation of the
emergent algorithm on a system consisting of LEGO Mindstorm Robots is further discussed along
with the most interesting experimental results. Copyright © 2009 IFSA.

1. Introduction
The evolution of information processing equipment and the need of adaptable digital control systems
generate an extraordinary spreading of digital equipment in all fields of life including military
applications, service industries, space exploration, agriculture, mining, factory automation, health care,
waste management, disaster intervention and domestic applications. Most of such equipment present in
diverse human activities is required t
