The device resembles a stingray, except it doesn’t patrol the water in search of prey.
It’s perched at the edge of the water, and rather than threaten humans, it aims to save them.
It’s much louder, too ― emitting a piercing, high-pitched alarm when it sees a motionless human head beneath the pool’s surface for more than 15 seconds.
From a corner of the pool at the Easton/Phillipsburg Branch of the Greater Valley YMCA, the Coral Manta 3000 knows a human head from any old beach ball. The machine, which the branch is testing on behalf of YMCAs across the country, uses artificial intelligence to recognize body parts and learn how humans act in the pool in an effort to prevent drownings.
