Continuous and rapid coverage of the unstructured disaster areas in search of possible survivors is a time critical operation where prior information about the environment is not available or very limited. Human navigation of such areas is definitely not feasible due to the nature of the debris. Localisation of possible survivors necessitates the uninterrupted navigation of robotic aiding devices within the rubbles without getting trapped into dead ends. This paper introduces firstly a goal-oriented exploration approach where prior information about possible survivors’ location information may be found. Whenever prior information is not available, the system is further extended as a second novel methodology to a prioritised exploration, guided by a percolation inspired finite state automaton that gives priority to navigation through connected voids. The evaluation of the proposed methodologies is done for different simulation scenarios with different number of robots cooperatively carrying the exploration task. © 2010 Inderscience Enterprises Ltd.
