“…These types of the mechanisms are usually used in small flapping wings with hovering capabilities. For example, in 2016, Jeon et al [41] designed a flapping actuation mechanism using a pair of six-bar linkage, based on their flapping wing MAV design requirements. In their study, several mechanisms were analyzed using a flexible multi-body dynamic analysis and the performance of each mechanism was evaluated [41].…”

A new strategy is proposed in order to effectively design the components of actuation mechanisms for flapping wing micro air vehicles. To this end, the merits and drawbacks of some existing types of conventional flapping actuation mechanisms are first discussed qualitatively. Second, the relationships between the design of flapping wing actuation mechanism and the entrance requirements including the upstroke and downstroke angles and flapping frequency are determined. The effects of the components of the actuation mechanism on the kinematic and kinetic parameters are investigated. It is shown that there are optimum values for different parameters in order to design an efficient mechanism. Considering the optimized features for an actuation mechanism, the design, analysis, and fabrication of a new hybrid actuation mechanism for FWMAV named "Thunder I" with fourteen components consisting of two six-bar mechanisms are performed. The results show that this designed hybrid actuation mechanism has high symmetrical flapping motion with hinged connections for all components. The proposed methodology for the modeling and fabrication of Thunder I's actuation mechanism can be utilized as guidelines to design efficient FWMAVs actuation mechanisms.Drones 2019, 3, 73 2 of 21 amplification. This mechanism could provide the hovering capability for a small size flapping wing NAV. As for flapping wing at PAV scale, Wood et al. [22] have developed modern flapping wings which use piezoelectric actuators to generate flapping motion. Selecting the appropriate actuator is considered as an important part for designing effective flapping wing. Depending on the type of the system, different actuators can be used to perform the mission including electric motors, piezoelectric elements, solenoids, and Shape Memory Alloys (SMA) wires [23][24][25][26][27].Research on flapping wing MAVs has led to a variety of actuation mechanisms which are designed for flapping motion. These actuation mechanisms are four-bar, five-bar, and six-bar mechanisms. As for the four-bar actuation mechanism, five types have been used, as shown in Figure 1 [28-30].Drones 2019, 3, x FOR PEER REVIEW 2 of 20 mechanism for motion amplification.

This paper presents the design process and experimental results of a brand new flapping and trailing edge control mechanism for a flapping wing micro air vehicle. The flapping mechanism, whose main components are fabricated from string, is suggested and optimized further by a modified pattern search method. The trailing edge control mechanisms for pitching and rolling moments are designed to be attached onto the present flapping mechanism in a modularized fashion. Prototypes of both mechanisms are fabricated and experimentally tested in order to examine the feasibility of the designs. It is expected that the present flapping mechanism will generate enough lift for the total weight of the vehicle. The present control mechanism is found to be able to supply sufficient control moment.
