RHODE ISLAND (CNN) - A beach in Rhode Island is using new potentially life-saving technology.  Meet "Emily," a state-of the art robotic lifeguard.  If a swimmer is in distress and a whistle is blown, Emily would be deployed by a lifeguard who would operate it with a remote control from shore.

Another lifeguard follows the four-foot-long buoy that can race through the choppy waters at 24 miles per hour acting as a floatation device until a lifeguard can catch up.

Emily is intended to assist, not replace the human lifeguards.
