From Wired's Danger Room, a report on DARPA's attempt to crowdsource UAV design:
Last year, the Pentagon asked DIY-drone enthusiasts to come up with the spy drone of the future. Twelve months later, it looks like they might need a little more time.
In an announcement posted online yesterday with little fanfare, Darpa announced that its UAVForge competition had ended — with none of the 140 teams emerging victorious in the quest to create a better spy drone. “The teams brought creativity and enthusiasm to the competition,” Jim McCormick, the Darpa program manager in charge of the contest, said in the statement. “The competition was more constructive than you might expect; there were many examples of teams helping each other.”
