A new bird-like robot, the “Robotic Avian-inspired Vehicle for multiple Environments” (RAVEN), could revolutionize drone and airplane takeoff. Researchers, as detailed in a recent *Nature* publication, have developed this crow-sized prototype capable of hopping, walking, and leaping like a raven. This unique ability offers a novel approach to aircraft launch.
The RAVEN’s innovative design allows for a simple leap-based takeoff, eliminating the need for runways or catapults required by most winged drones. Its flexible legs and joints, including hips, articulated ankles, and an elastic toe, enable it to navigate uneven terrain. This adaptability is a significant advantage over conventional drones and aircraft.
Furthermore, the researchers highlight the superior energy efficiency of the RAVEN’s jumping takeoff. They found it to be approximately ten times more efficient than traditional methods, while also providing higher takeoff speeds. This makes it a promising model for scaling up the technology to larger drones and even conventional aircraft.
The potential applications extend beyond improved takeoff. The RAVEN’s capabilities could prove invaluable on aircraft carriers where space is limited, and for landing aircraft in challenging environments. This technology represents a significant advancement in aeronautical engineering.
This isn’t the first avian-inspired robot designed to improve flight. Straight Arrow News has previously reported on “PigeonBot,” another robotic bird focused on enhancing aircraft stability and preventing barrel rolls. The RAVEN represents a significant step forward in achieving more efficient and versatile aerial vehicles.
