Drone aircraft are no longer curiosities—they're widely used in recreation, transportation, and even warfare. Most of these flying machines use rotary-wing quadcopter designs, which allow them to take ...

Stuttgart/Irvine – If a Tyrannosaurus Rex living 66 million years ago featured a similar leg structure as an ostrich running in the savanna today, then we can assume bird legs stood the test of time – ...

Engineers at Stanford University have been working on a robot that is part quadrotor flying drone and part peregrine falcon. The upper half of the robot looks like a common quadrotor drone designed to ...

Scientists have built a bird-inspired robot with legs that can walk on the ground, hop over obstacles and jump into flight, an advance that may lead to the development of drones for complex terrains.

EPFL’s RAVEN is a fixed-wing drone that can take off without a runway using bird-inspired legs. EPFL’s RAVEN is a fixed-wing drone that can take off without a runway using bird-inspired legs. is a ...

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 ...

Many organisms can transition smoothly from one mode of locomotion to another, often by using the same body parts. For example, flying fish use their fins to steer underwater, and these same ...
