EPFL: This drone shrinks to fit

Researchers at the University of Zurich and EPFL have created a robot that shrinks to fit through gaps, a feature that could make it perfect for search and rescue missions. The researchers initially created a drone that could assess man-made gaps and squeeze through in seconds using only one camera. This extra feature — a scissor-like system to shrink the drone in flight — makes it even more versatile and allows these drones to react to larger or smaller gaps in nature.
