Researchers unveil RAVEN robot that jumps and flies using spring-loaded legs

Researchers at École Polytechnique Fédérale de Lausanne and the University of California have introduced RAVEN, a bird-inspired robot that uses spring-loaded legs to jump into flight. This design allows for both ground movement and aerial capability. The robot mimics the jumping behavior of crows, which researchers observed to be an energy-efficient way to take off. RAVEN features a fixed-wing body, a split-V tail, and a front-mounted engine with a single propeller. Testing confirmed RAVEN's ability to walk, hop, and jump while its rotor spins, demonstrating effective navigation in various environments. This innovation could enhance the functionality of drones for tasks like search-and-rescue and environmental monitoring.
