Researchers put bird legs on a drone so it can take off by jumping
Briefly

The Robotic Avian-inspired Vehicle for multiple ENvironments (RAVEN) employs bird-inspired legs for improved agility and efficiency, allowing it to operate in challenging terrains without runways.
This innovation blends mathematical modeling with physical design, utilizing springs and motors to emulate avian strength, critical for maneuvering and effective takeoff in a compact form.
