Bird-Inspired Robot 'Floaty' Hovers Without Propellers by Riding Natural Airflows
A German research team has developed 'Floaty,' a bird-inspired flying robot that achieves stable hovering without propellers. Modeled on the kestrel's ability to exploit updrafts and headwinds, Floaty uses onboard sensors and control systems to harness natural airflows, dramatically reducing energy consumption while maintaining airborne stability. The design aims to bridge the gap between agile but power-hungry multirotor drones and efficient but non-hovering fixed-wing aircraft.
