Clever Buoy is a rapid prototype, proof of concept R&D project that aims to develop shark detection technology. They are smart ocean buoys that detect large swimming objects, like sharks, and send real-time valuable information to lifeguards on the beach.
The Clever Buoy utilises new sonar technology to detect shark-sized objects in coastal waters. The sonar is looking for large shark-sized objects that are swimming. When detection is made by the Clever Buoy, an alert will be sent to relevant audiences using Google+ circles, via the Optus Network.
Shark detections are alerted via a signal on shore. The data is also shared with relevant audiences using Google+ circles, so that the right information, reaches the right people, at the right time.
The Clever Buoy in its BETA, R&D phase, currently detects a shark-like object of two meters or more in length. Future development of the buoy will involve inbuilt decision–making systems, which will attempt to differentiate the object as a shark or mammal such as a dolphin or whale, with an appropriate response.
The Clever Buoy uses sophisticated software that differentiates between the length of an object, and its propulsion through the water.
In testing it has been identified that sharks create a distinctive sonar signature and swimming pattern that is different to mammals. The Clever Buoy sonar will adapt and develop with increasing knowledge of the difference between a shark’s sonar signature and movement pattern and that of other sea life. The development is similar to the development of ‘face recognition’ software in humans.
Future iterations of the Clever Buoy could potentially identify acoustic signatures, anatomical characteristics such as jaw size and lungs, as well as swimming patterns to continually develop more sophisticated detection algorithms.
Signatures were captured during testing in the Sydney Aquarium and the Abrolhos Islands in Western Australia that will enable the Clever Buoy to further differentiate between sea life in the future. For instance, a human, a dolphin, seal, large ray or school of fish create very different patterns on the sonar.
The sonar and its associated software is able to identify a shark-like object of two meters or more in length. The system utilises intuitive software that continues to develop and learn the details of what it is designed to detect.
Traditional sonar has had limited success in being able to detect sharks. The Clever Buoy uses new, intuitive software that continues to develop and learn the details of what it is designed to detect.
The Clever Buoy’s sonar has successfully identified sharks during testing phases in Sydney Aquarium and the Abrolhos Islands.
