O-Drone / Drone for water rescue

Fast and safe rescue is required when someone falls into the water, but if you are swimming to the drowning people to rescue them, it is the time-consuming and dangerous way for both of the rescuer and the drowning people and if you are throwing a flotation device such as rescue tube, rope etc., it is the inaccurate way to reach the person and even the drowning people are far away from land, it is impossible to throw a flotation device to them.
Using O-Drone, you can easily access the range of the drowning people quickly and accurately, and by spreading the rescue tube which is built in the drone, can save the drowning people safely.
