Flying insects are interesting dipteras with an outstanding wing structure that makes their
flight efficient. It is challenging to mimic flying insects and create effective artificial flapping …

Most insects and hummingbirds can generate lift during both upstroke and downstroke with
a nearly horizontal flapping stroke plane, and perform precise hovering flight. Further, most …

Traditional flapping-wing robots (FWRs) obtain lift and thrust by relying on the passive
deformation of their wings which cannot actively fold or deform. In contrast, flying creatures …

We present an unsteady blade element theory (BET) model to estimate the aerodynamic
forces produced by a freely flying beetle and a beetle-mimicking flapping wing system …

We briefly summarized how to design and fabricate an insect-mimicking flapping-wing
system and demonstrate how to implement inherent pitching stability for stable vertical …

Allomyrina dichotoma has a natural ultra-high flying ability and maneuverability. Especially
its ability to fly flexibly in the air, makes it more adaptable to the harsh ecological …

In this work, we develop an artificial foldable wing that mimics the hind wing of a beetle
(Allomyrina dichotoma). In real flight, the beetle unfolds forewings and hind wings, and …

To maintain flight, insect-scale air vehicles must adapt to their low Reynolds number flight
conditions and generate sufficient aerodynamic force. Researchers conducted extensive …

In this paper, a simple but effective design for implementing a negative wing twist in a beetle-
mimicking wing system is presented. The effectiveness of the design in terms of force …

The development of flapping-wing micro air vehicles for many applications, such as
hazardous environment exploration, reconnaissance, and search and rescue, demands …
