Take cover, it's a drone with a nail gun! – TechCrunch

The FAA has warned against equipping your drone with weapons such as flamethrowers and handguns. But can a nail gun really be considered a weapon -- that is, outside of Quake? Let's hope not, because roboticists at the University of Michigan have made a roofing drone that uses that tool to autonomously nail shingles into place. In a video shot in UM's special drone testing habitat, the craft flies up, approaches its bit of roof, and gingerly applies the nail gun before backing off and doing it a couple more times. It's very much just a tech demonstration right now, with lots of room to improve.
