Shape-changing Folding Drone That Can Fly Through Narrow Gaps

Drones and robots are already being used for search & rescue and other challenging missions. Not all drones are capable of flying through narrow gaps though. University of Zurich and EPFL researchers have developed a new quadcopter that makes itself smaller and retracts its propellers to fit through narrow holes. The design is inspired by birds that fold their wings mid-air to fly through narrow openings.

This morphing drone can adopt different shapes to get things done in the field. The above video shows it in action.
