New techniques teach drones to fly through small holes

Researchers at the University of Maryland are adapting the techniques used by birds and bugs to teach drones how to fly through small holes at high speeds. The drone requires only a few sensing shots to define the opening and lets a larger drone fly through an irregularly shaped hole with no training.
Nitin J. Sanket, Chahat Deep Singh, Kanishka Ganguly, Cornelia Fermüller, and Yiannis Aloimonos created the project,called GapFlyt, to teach drones using only simple, insect-like eyes.
