SpiderMAV Drone Shoots Webs for Perching and Stabilization

Perching is turning out to be a very desirable skill for aerial robots. The ability to land on walls or ceilings, rather than having to go to the ground, gives a drone the advantage of being high up in the air (probably why you're using a drone in the first place) without the disadvantage of having to spend a lot of energy not falling. We've seen lots of different perching techniques, most of them bio-inspired, including many different flavors of claws, spines, grippers, and adhesives. One of the best perchers in the animal kingdom (although it rarely gets credited as such) is the spider. And spiders don't just perch: They build infrastructure.
