Robot lifeguard. How neat it this!!!!

EMILY the Robot Lifeguard is a motor-powered flotation device that uses sonar to locate drowning persons. Human lifeguards control the device remotely from shore, but it could be independent as soon as 2011. Lifeguards can also communicate with the victim via EMILY's on-board camera and speakers. Although EMILY currently patrols only Malibu's Zuma Beach, famous for its excellent surfing conditions and occasional rip currents, 24 more beaches will soon employ the device, according
