Design and Development of a Hovering Flapping Twin-Wing Robot

Units : Department of control engineering and system analysis | ULB809

Description :

The aim of this work is designing and constructing a flapping twin-wing robot of the size of hummingbird (Colibri in French)
capable of hovering. Our robot currently has a total mass of 22 g, a wing span of 21 cm and a flapping frequency of 22 Hz; it is
actively stabilized in pitch, roll and yaw by changing the wing camber with a mechanism known as wing twist modulation. The proposed
design of wing twist modulation effectively alters the mean lift vector with respect to the center of gravity by reorganization of
the airflow. This mechanism is modulated by an onboard control board which calculates the corrective feedback control signals
through a closed-loop controller in order to stabilize the robot. The vertical position is controlled manually by tuning the flapping
frequency. The robot has demonstrated successful hovering flights with an on-board battery for the flight autonomy of one minute.
