<ul><li>Researchers have developed a bird-shaped robot called RAVEN that can hop, walk, and leap into flight like a raven.</li><li>RAVEN combines a fixed-wing design with articulated legs, enabling it to traverse various environments and take off more efficiently.</li><li>The prototype can use its flexible legs to walk on the ground and overcome challenging terrain.</li><li>Jumping takeoffs are found to be 10 times more energy-efficient than static takeoffs, potentially improving the reliability and landing potential of drones and planes.</li></ul>
