Researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and UC Irvine have developed a revolutionary new drone called RAVEN, capable of landing and taking off in challenging environments that would leave traditional fixed-wing aircraft stranded. Inspired by bird-like legs, RAVEN boasts articulated legs with springs and motors that allow it to walk on rough terrain, jump over obstacles, and leap into the air for takeoff without a runway.
Unlike quadcopter drones, which rely on four motors and are less energy-efficient, RAVEN uses a single motor paired with gliding for flight. The drone’s unique design features include powerful avian-inspired tendons and muscles in its legs, as well as simplified feet with passive elastic joints that prevent constant face-planting.
RAVEN’s capabilities set it apart from other fixed-wing drones, which can only perform short takeoffs and landings. This new drone can walk across rough terrain, jump over gaps, and hop onto obstacles up to 10 inches high. Its advanced legs also allow it to reposition itself in areas that may be hazardous or restricted to humans.
With its larger operational range, RAVEN requires less power than a quadcopter drone, making it an attractive option for search and rescue missions, environmental monitoring, and other applications where traditional drones have limitations.
