In the not too distant future the world is going to be abuzz with quadrotors flying about making deliveries, monitoring traffic, and of course spying on everyone: a skill this gecko-like craft is particularly adept at. Thanks to a special dry adhesive it's able to stick and unstick from surfaces, letting it land and perch almost anywhere.
Developed as a joint research project between Stanford and the University of Maryland, the quadrotor is an impressive example of biomimicry, where scientists attempt to recreate features and capabilities of living things. At the moment the quadrotor sticks best to smooth acrylic surfaces, but eventually, like a gecko, it should be able to cling anywhere letting it watch and listen like the proverbial fly on the wall.
