The FAA has warned against equipping your drone with weapons[1] 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[2].
In a video shot in UM’s special drone testing habitat[3], 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. For one thing, the drone doesn’t use onboard cameras, but rather a system of static cameras and markers nearby that can tell exactly where the drone is and where it needs to go.
This is simpler to start with, but eventually such a drone should be able to use its own vision system to find the point where to touch down. Compared with a lot of the computer vision tasks being accomplished out there, finding the corner of a roof tile is pretty tame.
Currently the drone is also free flying and uses an electric nail gun; this limits its flight time to about 10 minutes and a few dozen nails. It would be better for it to use a tether carrying power and air cables, so it could stay aloft indefinitely and use a more powerful pneumatic nail gun.
Drones are already used for lots of industrial applications, from inspecting buildings to planting trees[4], and this experiment shows one more area where they could be put to work. Roofing can be both dull...
