Professor David Sheffler and his engineering students at the University of Virginia developed a military grade drone that can be produced on a 3-D printer.
The drone uses an Android smartphone that acts as the central processor.
From the video: The Razor is a 3D-printed, hand-launchable, autonomous U.A.V. developed by Professor David Sheffler in partnership with the Mitre Corporation. The flying-wing aircraft’s design was developed through a rapid prototyping process and refined over the course of several iterations. The aircraft was built with freely available off-the-shelf parts, including an Android smartphone that acts as the central processor.
