This bird-inspired drone is more energy efficient and proficient at complex flight maneuvers

Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland developed a Robotic Avian-inspired Vehicle for Multiple Environments (RAVEN) by adding hind limbs to a fixed-wing design. The final result is a drone that takes off quicker than a traditional model and performs complex maneuvers that mimic real birds....
