Abstract:
Presented herein are an actuation system and a flapping wing micro aerial vehicle system. In one embodiment, for energy efficiency and to achieve a resonant system, the flapping wing is directly driven using conventional DC motors coupled with torsion springs. Using a transmission gear, the motor is designed to operating at an efficient speed, but generates an overall reciprocal motion to the wing. Closed loop control is applied to achieve tracking of the desired wing motion kinematics, the frequency of which is tuned to match the resonant frequency of the system. We also show that wing kinematic control can be achieved by tracking trajectories with different amplitude and bias, therefore creating flight control forces and torques.

Abstract:
A novel electromagnetic actuator designed to operate at system resonance, used in the construction of a unique vehicle system, is presented herein. An exemplary embodiment of the vehicle system is based on an electromagnetic actuator coupled to a plurality of actuating members of a micro aerial vehicle. Attributes of this type of actuation offer several enhancements over traditional approaches. The unique use of an electromagnetic actuator lends itself to a near unlimited number of coil cross-sectional designs that can be optimized to meet performance requirements while maintaining minimal costs of fabrication.
