The Monospinner: a controllable flying vehicle with a single moving part in the ETH Zurich Flying Machine Arena

This video introduces the monospinner, the mechanically simplest controllable flying machine in existence. It has only one moving part (the rotating propeller). The vehicle features no additional actuators or aerodynamic surfaces.

The monospinner cannot hover like a standard multicopter. However, an unconventional equilibrium is found by analyzing the vehicle’s dynamics. For a certain constant
