EMILY the robotic lifeguard can rescue people just like a lifeguard! This robot can rescue up to eight people. It doesn’t have propellers so the people being rescued won’t get hurt. EMILY can travel up to 800 yards and move up to 22 mph. The EMILY is priced at $10,000. EMILY comes with a remote control and an app to guide where the buoy like lifeguard travels.

This related to engineering seeing as this ROBOTIC lifeguard, which is named E.M.I.L.Y was constructed by many people when it only started off as a thought. An idea. There is many programming gone into this, even many materials.
