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 ...

Researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and UC Irvine have developed a drone capable of landing and taking off in areas that would otherwise leave a ...

They're just hard to launch and land. A team of Swiss researchers has devised a possible solution by slapping some legs on a drone known as the RAVEN. This new drone takes its inspiration from ...

“allowed the drone to take off in a wider range of circumstances and at higher initial speed, thus leading to a more stable take-off”. With further optimisation, researchers said Raven’s leg ...

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.
