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 ...

Soaring and gliding birds harness the free energy of natural air currents to provide the forward (thrust) and upward (lift) momentum required for flight. These birds can travel immense distances and ...

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 ...

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 ...

Embrace wobble to level flight without a horizon Shin et al. took inspiration from the anatomy of birds to design a multifunctional robotic leg that enables RAVEN, the authors’ uncrewed aerial ...

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.

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 ...

Led by paleontologist Jingmai O'Connor from the Field Museum of Natural History, the study investigates the evolutionary ...

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 ...

A team of roboticists at École Polytechnique Fédérale de Lausanne, working with a colleague from the University of California, has designed, built and demonstrated a bird-like robot that can launch ...

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.

But nature has other ideas. Birds achieve flight control through complex, coordinated movements where different body parts can affect multiple degrees of freedom simultaneously. Now, researchers ...
