The use for unmanned drones increases every day. This time it's to keep an eye on the beaches of Queensland, Australia to look out for swimmers in trouble — and, of course, any sharks lurking too close.
Surf Life Saving Australia will be deploying the Aerobot Ring, a co-axial hexacopter, in a trial of the drones' effectiveness. The drones are roughly three feet wide and have a payload capacity of around 15 pounds for a flight time of 15 minutes. They'll carry cameras to keep an eye on the water, as well as life buoys to drop to those in distress. Plus, there's a siren to warn people of potential trouble before it happens.
