In recent years, researchers and engineers have increasingly turned to solutions they have seen in nature, and copied them. This trend began long before our time. The Wright brothers, for instance, drew inspiration for their flying machine from the mechanics of pigeon wings in flight.
For instance, Professor Stuart Burgess and his research team at the University of Bristol (UK) have developed a tiny flying robot weighing less than 20 kilograms. It flies like a dragonfly.
Professor Burgess acknowledges that the robot is no match for a dragonfly that is a very sophisticated creature that can fly in any direction.
