There is little design artifice to this device. This EMILY (Emergency Integrated Lifesaving LanYard is a $3500 robot-lifeguard purchased for Malibu lifeguards. Remote-controlled and capable of 28 mph, product testing confirms that EMILY just might be smarter than David Hasselhoff and more buoyant than Pamela Anderson.
Popsci lays out how it works:
Step 1 Ready for action
EMILY patrols solo or is thrown into the sea from the beach, a helicopter or a ship.
Step 2 Search and rescue
EMILY's sonar finds a distressed swimmer, and it jets toward him at 28 mph.
Step 3 Mission accomplished
A swimmer holds onto EMILY as it gently brings him to shore or waits for a lifeguard. The robot can travel up to 80 miles on a single battery charge.
