Emily is a tough, remote-controlled robotic lifeguard

The partnership was formed in 2001 to develop a drone that can monitor whales, but it continued to evolve until it led to Emily's creation. Emily's current iteration has two-way radios rescuers can use to talk with the people stranded in the water. It also has a video camera that sends live feeds to responders' phones and lights for night rescues. Emily can be thrown off helicopters and do just fine, thanks to its Kevlar and aircraft-grade composite components. The Navy recently demonstrated its latest version at the Naval STEM Expo and Sea-Air-Space Exposition on May 15th and 16th.
