Japan has geographical conditions that make it prone to being affected by natural disasters. In the event of a disaster such as an earthquake or typhoon, floods, landslides and buildings collapse. In this situation, evacuation routes that have been determined may change dynamically. We focused on the possibilities of drone. In this research, we obtain safe guidance route in dynamic environment and guide victims and the headquarters can watch these information by the drone. As a result, using “ROS” (robot operating system) for system implementation and we checked the logic in the simulation.
