On June 21, 2021, ARF (Advanced Robotics Foundation) and its affiliates succeeded in fully autonomous flying across Tokyo Bay with a flight distance of 50 km between Yokohama and Chiba, Japan. It was a complete BVLOS flight without an any observer of Tokyo Bay by small drone like kite plane of 24kg. A drone connects Yokohama and Chiba, which are big cities of Yokohama with 4 million population and Chiba with 1 million, by using the ultra-low airspace over Tokyo Bay. It was a demonstration experiment to build a distribution highway. We actually transported implants and dental technicians worth 500,000 yen. It is also an emergency drone that can carry out the mission as a disaster prevention and mitigation system for earthquakes and typhoon as natural disaster. It took two years from the conception. It means that the technical hurdles for safely flying a long distance of 50 km in Tokyo Bay, where there is Tokyo International Airport (Haneda Airport) and many large ships go around, are extremely high. And it was not easy to get a flight permit from the Civil Aviation Bureau of the Ministry of Land, Infrastructure, Transport and Tourism of Japan. In this presentation, the introduction of the progress in the previous two years including technical issues, the future plans and prospects will be presented.

Design and Control of a Camber Morphing Wing Aircraft
Associate Professor, Bruce W. Jo, Ph.D.
Department of Mechanical Engineering at State University of New York (SUNY), USA & Korea
Wing morphing technologies in general aim to optimize aircraft’ efficiency by changing and adjusting the shape of wings in compliance to corresponding flight conditions. Among many types of wing morphing, suggested variable camber compliant morphing in airfoil morphing enables aircraft to have seamless, conformal, and energy and noise effective change of wing geometry that significantly reduces drag force or lift-drag ratio. Unlike typical approaches of using smart materials or partial morphing of trailing-edge, mechanism-driven camber morphing wing via linear actuators enables fixed wing aircraft wing to adjust camber rates conformally, dynamically, and firmly along the wing span. For realization of actual flight and control of camber morphing wing aircraft, it is of interest (1) to investigate the nature of structural and aerodynamical behaviors of camber morphing wings while flight, (2) to study difference and similarity between the conventional wing and the camber morphing wings in control aspects, (3) to design and implement the skin structure of camber morphing wings along with characteristics of 3D printed structure. This presentation covers overview of morphing technologies, motivation and benefits of camber morphing, design of control allocation aspect of camber morphing wings, and design and implementation of skin structure for camber morphing wings with perspectives of 3D/4D printing.

Collision recovery of a beetle-inspired flapping-wing robot

Rhinoceros beetle is one of the largest insects that performs many remarkable modes of locomotion such as flying, crawling, and even burrowing their way underground. In addition, their hindwings can be folded and tucked under the elytra for protection when at rest, and unfolded to operate as flat membranes that generate the aerodynamic forces required for flight. The beetle thus is a good reference for developing a similar-scale flapping-wing robot. In this talk, we first introduce the 16 g beetle-inspired, motor-driven, KUBeetle-S robot, which is truly insect-like in terms of tailless and two-winged configuration, attitude control approach, and hovering flight capability. The robot could remain up to 9 minutes in the air, making it the lightest two-winged robot so far that can sustain free controlled flight with all onboard components. We then present a study on how the beetle and robot survive in-flight wing collision. We demonstrated that the folding mechanism in the beetle’s hindwing serves a crucial shock-absorbing function during in-flight collisions by collapsing and redeploying rapidly (< 5 ms) within a single stroke. We then built a beetle-inspired collapsible wing that can be passively folded and rapidly unfolded (< 7 ms). Implementing the wing on a flapping-wing robot, we showed that the folding mechanism enables the robot to fly safely after collisions. Otherwise, in absence of the folding mechanism, the robot tumbles. This initial result promises to develop a collision-tolerant robot for applications in confined space and cluttered environments.
