That’s where RAVEN stands out. This experimental winged drone has little mechanical legs that let it walk, jump over obstacles and leap quickly into the air. Engineers from Switzerland and the U ...

Their Robotic Avian-inspired Vehicle for multiple ENvironments (RAVEN) trades traditional landing gear for a pair of bird-inspired articulated legs that allow the drone to walk around, hop over ...

The key challenge in attaching legs to drones was that they significantly increased mass and complexity. State-of-the-art robotic legs were designed for robots walking on the ground and were too ...

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 ...

The Swiss research team at the École Polytechnique Fédérale de Lausanne found that by adding bird-like legs to a fixed-wing puller-propeller drone, their machine, aptly deemed Raven (Robotic ...

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.
