A Note on the Electromechanical Design of a Robotic Hummingbird

This paper analyzes the lift-production system in hovering of flapping wing robot COLIBRI size a hummingbird. The first examines mechanism for which new gear transmission is proposed to reduce friction and facilitate assembly. Next, sensitivity analysis performed on size. Then, discusses several options gearbox, various DC motors two battery configurations (a single or batteries series) minimize heat generation increase flight time. configuration involving has been found more effective. time predicted using Shepherd’s discharge model it confirmed by an experiment. sustains endurance nearly 5 min produce lift force equal weight robot.
