Drones could soon become a standard life-saving tool for lifeguards and rescue teams.
Even just a few seconds in the water can mean the difference between life and death, and robots can fly much faster than people can swim. On his best day, Michael Phelps swims at 6 mph, but drones can reach speeds of 50 mph or more.
Microdrones just released a new video that shows how unmanned aerial vehicles can drop off flotation devices to help save people from drowning.
Last summer, a fire chief in Maine used his personal drone to assist with a river rescue. While the rescue team worked on the two-hour rescue, the fire chief flew his personal drone to deliver a life jacket to the stranded people.
