Flapping Wings with DC-Motors via Direct, Elastic Transmissions

Muhammad Azhar, Domenico Campolo, Gih-Keong Lau, Metin Sitti

Abstract


Prototype developed in this study demonstrates that, in concert with elastic transmission, DC motors can be utilized to directly actuate wings at high frequencies and large angles. Tuned to resonate, elastic transmission evades the DC motor from producing high torque to actuate the prototype’s inertia. Wings are directly driven by the DC motor to avoid the application of nonlinear transmission that will diminish the benefit of the resonance. Without any nonlinear transmission, the reciprocating motion of the wings is constructed by driving the DC motor sinusoidally instead of continuous spin.
