Bird-Inspired Drone Combines Walking, Hopping, and Jumping for Flight

EPFL researchers unveil RAVEN, a fixed-wing drone with avian-inspired legs that enable energy-efficient takeoffs and versatile ground mobility.

RAVEN, developed by EPFL researchers, uses bird-like legs to walk, hop, and jump into flight, mimicking the multimodal locomotion of birds like crows and ravens.
The drone's spring-loaded legs improve energy efficiency during takeoff, requiring less power compared to traditional fixed-wing drones that rely on runways or launchers.
Weighing 0.62kg, the drone's design integrates lightweight articulated legs with springs and motors to replicate avian tendons and muscles, enabling diverse movements on rough terrain.
RAVEN's capabilities include navigating uneven surfaces, jumping over obstacles, and autonomous takeoff in confined or hazardous environments without human intervention.
Potential applications include disaster relief, delivery in challenging terrains, and environmental monitoring, with ongoing research focused on improving landing and adaptability.
