A robot with bird-like legs that can walk, hop, leap and jump for take-off into flight has been designed in Switzerland in an engineering breakthrough that could enable aircraft to operate in ...

Most drones on the market are rotary-wing quadcopters, which can conveniently land and take off almost anywhere. The problem is they are less energy-efficient than fixed-wing aircraft, which can fly ...

Have you ever wondered why an airplane has a vertical tailfin? The plane needs it to stabilize its flight. Since flying without a vertical tail is much more energy-efficient, the aviation industry has ...

Taking design inspiration from an ostrich, the BirdBot needs fewer motors than comparable legged robots. A few facts about ostriches: It took just a few million years for terrestrial birds to refine ...

This bird-like robot has a claw that it could use to perch on branches it has flown to. It could potentially be useful for collecting samples in hard-to-reach places or silently observing animals in ...
