Watch insect robot use static to stick landing - Futurity

Small drones need to stay aloft to do their jobs--whether it's searching for dangerous gas leaks or remotely monitoring atmospheric conditions. But the effort can quickly drain battery power. Now, scientists have created RoboBees, insect-sized flying robots that have a switchable electro-adhesive that allows them to perch on materials such glass, wood, or a leaf, using roughly 1,000 times less power than sustained flight. "One of the biggest difficulties with building insect-sized robots is that the physics change as you go that small. A lot of technologies that have been deployed successfully on larger robots become impractical on a centimeter-sized robot," says coauthor Sawyer Fuller, assistant professor of mechanical engineering at the University of Washington.
