Drones may have gone mainstream, but it's not everyday that you see an entry to that marketplace from a veteran technologist with a history of popularizing clever little robot vacuum cleaners. Having already built a pair of industry-oriented drones, Roomba co-designer Helen Grainer's startup CyPhy Works has made its first flirt with the consumer space with a moderately priced six-rotor drone that takes flight with a swipe of the smartphone screen.
In seeking a compromise between helicopters and fixed-wing aircraft, engineers in recent years have opted for tilt rotors, but NASA has dusted off and improved on a tilt wing aircraft design that takes off and lands like a helicopter and flies like an airplane. Called the Greased Lightning, or GL-10, the unmanned prototype made a successful vertical takeoff and transition to horizontal flight at Fort A.P. Hill, not far from NASA's Langley Research Center in Hampton, Virginia.
