“…In [6], researchers at University of California, Berkeley have designed two PID controllers for decoupled 6-DoF longitudinal and lateral dynamics models, and they are executed onboard at 400 Hz to drive 13-gram ornithopter during cruise flight. In [142], DelFly II MAV accomplished autonomous station-keeping in a small wind-tunnel, and similarly two PID controllers are developed for decoupled longitudinal and lateral dynamics control. .…”

This paper provides a brief overview on the recent advances of small-scale unmanned aerial vehicles (UAVs) from the perspective of platforms, key elements, and scientific research. The survey starts with an introduction of the recent advances of small-scale UAV platforms, based on the information summarized from 132 models available worldwide. Next, the evolvement of the key elements, including onboard processing units, navigation sensors, mission-oriented sensors, communication modules, and ground control station, is presented and analyzed. Third, achievements of small-scale UAV research, particularly on platform design and construction, dynamics modeling, and flight control, are introduced. Finally, the future of small-scale UAVs' research, civil applications, and military applications are forecasted.

“…Wind tunnels are an effective tool to investigate flapping-wing flight and aerodynamic characteristics [ 29 ]. The wing tip trajectories of the hind wings of a beetle species ( Protaetia brevitarsis ) were captured during wind tunnel tests and, based on the results, bioinspired wings and a linkage-mechanism flapping system were designed [ 26 ].…”

When beetles are not in flight, their hind wings are folded and hidden under the elytra to reduce their size. This provided inspiration for the design of flapping-wing micro aerial vehicles (FWMAVs). In this paper, microstructures and nanomechanical properties of three beetle species with different wing folding ratios living in different environments were investigated. Factors affecting their flight performance, that is, wind speed, folding ratio, aspect ratio, and flapping frequency, were examined using a wind tunnel. It was found that the wing folding ratio correlated with the lift force of the beetles. Wind speed, folding ratio, aspect ratio, and flapping frequency had a combined effect on the flight performance of the beetles. The results will be helpful to design new deployable FWMAVs.

“…For the forward flight condition, autonomous precision wind tunnel flight has already been achieved with quadrotors 46 and fixed wings, 47 but FWMAVs are much more challenging to control, 48 because of more complex dynamics and stricter weight and size restrictions on on-board computers and sensors. Our previous effort achieved the first successful autonomous windtunnel flight of an FWMAV, 49 but further improvements were still necessary to achieve the position and flight state stability necessary to perform such in-flight flow visualisation experiments.…”

Flow visualisations are essential to better understand the unsteady aerodynamics of flapping wing flight. The issues inherent to animal experiments, such as poor controllability and unnatural flapping when tethered, can be avoided by using robotic flyers that promise for a more systematic and repeatable methodology. Here, we present a new flapping-wing micro air vehicle (FWMAV)-specific control approach that, by employing an external motion tracking system, achieved autonomous wind tunnel flight with a maximum root-mean-square position error of 28 mm at low speeds (0.8-1.2 m/s) and 75 mm at high speeds (2-2.4 m/s). This allowed the first free-flight flow visualisation experiments to be conducted with an FWMAV. Time-resolved stereoscopic particle image velocimetry was used to reconstruct the three-dimensional flow patterns of the FWMAV wake. A good qualitative match was found in comparison to a tethered configuration at similar conditions, suggesting that the obtained free-flight measurements are reliable and meaningful.
