VTOL Drone Would Land, Refuel and Take Off By Itself

Drones can do just about everything autonomously these days, but most systems still require human assistance to land, refuel and take off again. Now, an aerospace startup, Aerovel, hopes to change that with its hover-capable Flexrotor drone that will come with its own automated docking station. No human ground support needed.
The notion comes from Tad McGeer, a Silicon Valley entrepreneur who created the small ScanEagle drone for fishermen and U.S. Navy SEALS. ScanEagle relied upon a pneumatic catapult launcher and "SkyHook" recovery pole, but the Flexrotor would do away with either requirement.

Instead, McGeer envisions his new drone using VTOL (vertical takeoff and landing) abilities. Tiny wingtip thrusters would do the same job as a helicopter's tail rotor and counteract the torque of the drone's main propeller in hover-mode.
