Soaring and gliding birds harness the free energy of natural air currents to provide the forward ... Birds may differ wildly in size, shape, and appearance, but almost all the surviving species have ...

Birds, however, beat us to it by about 150 million years. From the labored flapping but majestic soaring of the largest Eagles to the mind-numbing speed and agility of exquisite neotropical ...

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 ...

RAVEN uses spring-loaded legs for energy-efficient flight. Inspired by crows, it can hop, walk, and launch into the air. Built by EPFL researchers with a fixed-wing design for flying.

Artificial Flight: Modern drones have become pretty advanced, but they are very energy-inefficient. European researchers decided to take inspiration from birds to develop a new type of drone that ...

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.

The pied kingfisher is a medium-sized, black-and-white kingfisher with a distinctive crest and a long, sharp bill ...

In the similar efforts, EPFL researchers have developed RAVEN (Robotic Avian-inspired Vehicle for multiple ENvironments), which uses its bird-inspired multifunctional legs to jump rapidly into flight, ...

While airplanes can use wing sweep or special designs to manage stability without a vertical tail, birds achieve rudderless flight more efficiently across diverse wing shapes without relying on ...

Researchers have developed a bird-like robot capable of walking, hopping, and leaping into flight. Named RAVEN (Robotic Avian-inspired Vehicle for multiple Environments), the design features ...
