An unmanned device designed for drowning rescue

Prevention and rescue work is considered an urgent and crucial job to ensure the safety and life of people. However, this job contains many unpredictable dangers and difficulties that rescuers encounter during the rescue process due to the lack of timely support equipment. Causing a threat to the safety and life of the victim as well as the rescue force. In this paper, we propose to design a drone to assist in rescue and help people in distress get out of drowning more quickly to increase the chance of survival for people in distress by using unmanned aerial vehicles (drones) to carry a self-pumping buoy. When detecting people drowning, the rescuer can control the drone carrying a buoy to automatically pump out the drowning person's position and release the buoy to the person in distress. Experimental results in a controlled environment show the feasibility of the device in service of rescue work. The device has been tested in specific areas such as football fields, lakes, and open spaces as well as areas with obstacles, and achieved the required results.
