As we know of velociraptors, things tend to go awesome once creatures learn how to open doors. The Verge writes,
The key to the design is the use of interchangeable adhesives on the drone’s base: microspines for digging into rough materials like stucco, carpet, or rubble, and ridged silicone (inspired by the morphology of gecko feet) for grabbing onto glass. Both microspines and silicone ridges only cling to surfaces in one direction, meaning they can be easily detached. With these in place, the micro-drones can pull well above their 100-gram weight, exerting 40 newtons of force or enough to lift four kilograms (about eight pounds).
