EMILY is an acronym for Emergency Integrated Lifesaving Lanyard, a robotic device used by lifeguards for rescuing swimmers. It operates on battery power and can be remotely controlled after being dropped into bodies of water. Using an impeller motor, EMILY can reach victims faster than a human lifeguard and function as a flotation device that can support up to 4-6 people. In 2012, lifeguards used EMILY to rescue a father and son caught in a rip current, demonstrating its effectiveness. A new gasoline-powered variant of EMILY collects weather data in the ocean for multiple days under a NOAA grant.
