“…Furthermore, the proposed flapping system with an extension spring shows good endurance. The flapping system with an extension spring has been working for more than an accumulated 1 h without fatigue failure since it was fabricated, while the one with torsional spring broke before 1 min of continuous operation [ 35 ]. This is due to the fact that by adjusting the

in Figure 3 , the flapping system with an extension spring can be designed that is always working in the allowed operating range, while the flapping system with torsion spring requires larger displacement than is allowed for commercially available torsion springs.…”

“…For the directly driven dual motor flapping wing system, helical or torsion springs have been chosen for elastic devices [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. In our previous study, we initially applied a torsion spring for a flapping system to implement a resonance flapping wing system [ 34 ]. However, we found that aligning the torsion spring axis with the flapping axis is not easy since one side of the spring should be fixed to the center of the rotation axis while the other side should be fixed to the body frame.…”

In this paper, we propose a platform for an insect-like flapping winged micro aerial vehicle with a resonant wing-driving system using extension springs (FMAVRES). The resonant wing-driving system is constructed using an extension spring instead of the conventional helical or torsion spring. The extension spring can be mounted more easily, compared with a torsion spring. Furthermore, the proposed resonant driving system has better endurance compared with systems with torsion springs. Using a prototype FMAVRES, it was found that torques generated for roll, pitch, and yaw control are linear to control input signals. Considering transient responses, each torque response as an actuator is modelled as a simple first-order system. Roll, pitch, and yaw control commands affect each other. They should be compensated in a closed loop controller design. Total weight of the prototype FMAVRES is 17.92 g while the lift force of it is 21.3 gf with 80% throttle input. Thus, it is expected that the new platform of FMAVRES could be used effectively to develop simple and robust flapping MAVs.
