Generally, when a water safety accident occurs, it is structured by using a life tube. Water safety equipment such as life jackets and life tube is prepared by the person who plays with the water,

However, drowning accidents are frequently caused by showing off their own swimming ability by themselves, or by enjoying the water play on a river or a beach without wearing the above water safety equipment due to lack of water safety equipment. In addition, even if a water safety device is worn, if a sudden abnormality occurs in the safety device, a drowning accident may occur as well.

For a distressed neighbor, it is possible to construct a submerged person by using a life tube or a rope outside the water. However, if the distance is long, the probability of rescuing the submerged person is low and even if the rescue is time consuming, Or the body may be fatal.

Thus, research has been conducted on techniques to safely rescue a lifeboat by transferring a lifeboat to a submerged person by using a drone (UAV) when a submerger occurs in a river, a lake, or the sea. In particular, Rapid and accurate delivery of life-saving tubes is required when they occur.
