Despite there being some researches about collaborative unmanned aerial vehicle, operations with this kind of robots are not yet occurring. Using adaptative concepts, a model to investigate search operations applied to multiple UAVs is proposed. The adaptative concepts fit very well with the dynamism present in search operations in unknown environment. Two mechanism of adaption are purposed. The first leads to a prioritization of the most likely cells in the probabilistic map and the second leads to a dynamic redivision of the subareas initially allocated. Theoretical calculations show an increase in efficiency by about 100%. The utility of collaborative UAVs is not only the increase in efficiency, but also the reduction of costs and risks for the crew. Furthermore, related works, UAV history, conclusions and suggestions for future researches are also presented.
