The Next Great Frontier for Drones Lies in the Ocean Depths

Now they look to the sea. Drones capable of underwater operation are little more than novelties at the moment, but the technology could advance marine research, revolutionize undersea cinematography, and let anyone explore places even experienced divers cannot reach. A handful of companies are leading this leap into the water. PowerVision, a Chinese robotics firm with 10 offices around the world, introduced its PowerRay underwater drone earlier this year. OpenROV of Berkeley, California, staged a successful crowdfunding campaign for the Trident, its remotely operated vehicle. These machines offer only limited practicality, but point the way to a future where consumer drones do all sorts of things beneath the waves.
