We have developed a robotic demining system as part of a multi-agent application (AgentStorm) for assisting human commanders in command and control scenarios run in the ModSAF (Modular Semi-Automated Forces) simulation environment. The robotic demining agents cooperatively clear paths, enabling simulated forces to breach minefields. The AgentStorm system is composed of 25+ communicating software components developed with the RETSINA agent architecture. It was successfully demonstrated for military observers in November 1999. Within the demining domain, we explore different multi-robot cooperation and communication strategies.
