Drones have been around for years; they offer features they give which are used for different purposes. Today, these devices have become more popular and their use in various fields is increasing rapidly. Among these applications, we can mention firefighting and rescue flying robots, which can be used in firefighting organizations, Red Crescent, and other rescue and operational organizations to identify accident centers and fire centers, and also manage operations. This article introduces the design and construction of a rescue flying robot, which, despite its large dimensions, has a low height in order to keep the maximum point of gravity low to the ground, and on the other hand, designing the robot as a coaxial quadcopter in terms of dimensions, construction costs and also, productivity can be considered more affordable. This is while naturally ۱۵ to ۲۰ percent of the efficiency of the lower engines will be lost due to the interference of the airflow.
