Problem

Drowning is the 3rd leading cause of unintentional injury death worldwide, accounting for 7% of all injury-related deaths. There are an estimated 320 000 annual drowning deaths worldwide.

Solution

The idea is to create an ocean rescue robot that detects distressed swimmers, sends out alerts to the person responsible and drives autonomously to victims to help them by providing easy grip handles to grab and secure themselves. 

Industry

There are about 4 types of solutions on the market for rescuing distressed swimmers:

1) Detectors for pools that are detecting distressed swimmers and sending out alerts to lifeguards.

Examples: Coral Drowning Detection, SwimEye, Poseidontech, Laifeguard

2) Detectors for beaches, using cameras above the water to detect swimmers in distress.

Example: Sightbit

3) Beach and ocean rescue robots that do not detect drowning swimmers but that are remote controlled to to drive to distressed swimmers and they are working as a buoy where the person can grab and hold above the water.

Examples: EmilyRobot. 

This robot is for beach and ocean rescue. Can be thrown from helicopter, boat, from the beach. Detects and goes to distressed people so he/she can hold on something. Speed: 23 MPH.

4) Wristband that keeps track of guests while swimming or playing in the pool and if a user stays too deep for too long the Sentag Drowning Detection system will immediately alert lifeguards.

Example: Sentag

Below are a few drowning detection projects (using AI and body-mapping techniques) that might be helpful in your R&D:

This study first investigates to find the suitable deep learning algorithms that can be used to detect objects and then an experiment is performed with the chosen algorithms to state the possibility to detect humans in an underwater environment and then evaluate performance of algorithms. Analysis showed that the Faster RCNN algorithm gave the best results, being able to detect and track humans in an underwater environment with a maximum confidence level of 99% even when humans are seen in various angles, postures, and variable lighting conditions.

This program will detect if a person is drowning. This project is still a work in progress, so it can only be implemented with a computer's webcam, and doesn't work completely yet.

Their website is off and not sure it’s possible to contact them but they are giving quite a good overview about their work progress.

Using YOLO object detection, this program will detect whether a person is drowning or not. This software can be used with a Raspberry Pi Camera, which can then be placed underwater with an appropriate case.
