Zothecula writes: Earlier this year, RTS Lab unveiled its concept for Pars, an aerial robot that flies out over a large body of water to air-drop life preservers near drowning victims. Like many design concepts, we weren't sure if this life-saving drone would ever become a reality, but it seems the Iran-based company was recently able to fund a working prototype and even test its capabilities in open water. Based on these initial tests, it's possible that this flying, GPS-guided lifeguard could be out there saving lives sooner than you think.
