EMILY Makes Waves, Saves Lives in Southern

摘要

For the past few years, the County of Los Angeles Fire Department, which also overseas 72 miles of coastline, has had a new helper. She's a good swimmer, she doesn't need to eat or take vacations, and she has helped lifeguards save people from drowning. She can swim at speeds up to 22 mph. Her name is EMILY, for Emergency Integrated Lifesaving Lanyard, and she is built by Hydronalix.
