“…In [79], by means of a vacuum pump and flexible skin, it was shown that it is possible to expand the vehicle flight envelope without gaps and discontinuities in the wing profile that would increase the drag, whereas in [80,81] a wing with a honeycomb-like structure was actuated …”

“…Another quantitative advantage is found when forces that provide (or go against) locomotion are shape-dependent. In flying or swimming gaits, where lift and drag forces directly depend on the shape of the vehicle or of the thrusters (either fins, wings or chambers), a morphing body could increase performance [88], decrease energy consumption [131], serve as a computational resource [144] and avoid flow disturbances [79].…”

Soft robotics and its related technologies enable robot abilities in several robotics domains including, but not exclusively related to, manipulation, manufacturing, human -robot interaction and locomotion. Although field applications have emerged for soft manipulation and human-robot interaction, mobile soft robots appear to remain in the research stage, involving the somehow conflictual goals of having a deformable body and exerting forces on the environment to achieve locomotion. This paper aims to provide a reference guide for researchers approaching mobile soft robotics, to describe the underlying principles of soft robot locomotion with its pros and cons, and to envisage applications and further developments for mobile soft robotics.

“…The morphing MAV wing designer have to consider the limitation in wing size, limited energy, complex morphing mechanism, and high aerodynamicwing structural interaction [4]- [6]. Therefore, earlier research on such MAV wing had concentrated more on the its manoeuvrability rather than understanding its aerodynamic performance [7], [8]. Thus, the influence of morphing mobility on drag performances was not well explored.…”

Abstract.Morphing wing is one of latest evolution found on MAV wing. However, due to few design problems such as limited MAV wing size and complicated morphing mechanism, the understanding of its aerodynamic behaviour was not fully explored. In fact, the basic drag distribution induced by a morphing MAV wing is still remained unknown. Thus, present work is carried out to compare the drag performance between a twist morphing wing with membrane and rigid MAV wing design. A quasi-static aeroelastic analysis by using the Ansys-Fluid Structure Interaction (FSI) method is utilized in current works to predict the drag performance a twist morphing MAV wing design. Based on the drag pattern study, the results exhibits that the morphing wing has a partial similarities in overall drag pattern with the baseline (membrane and rigid) wing. However, based CD analysis, it shows that TM wing induced higher CD magnitude (between 25% to 82% higher) than to the baseline wing. In fact, TM wing also induced the largest CD increment (about 20% to 27%) among the wings. The visualization on vortex structure revealed that TM wing also produce larger tip vortex structure (compared to baseline wings) which presume to promote higher induce drag component and subsequently induce its higher CD performance.

“…In this paper focus is placed on the deliberate exploitation of the elastic properties of a main wing that is actively deflected between different configurations to provide roll control authority. This concept studied has been previously studied by Bolinches et al [12] and can be classified using the scheme of [11] as an out of plane morphing wing which uses a change of camber and a compliant mechanism.…”

The development of new technologies -such as rapid prototyping -and the use of materials with improved properties -such as highly resistant extruded polystyrene foam which can be easily and precisely shaped, while conserving its mechanical properties -allow researchers to improve design concepts. This paper details the development of a new set of morphing wings for a 15kg maximum take-off weight Unmanned Aerial Vehicle (UAV) from concept design, to flight tests, including modelling, design optimisation, construction and wind tunnel tests. A set of comparator equivalent conventional wings have been used throughout in order to be able to judge any benefits stemming from the adoption of morphing technology. The paper shows that the morphing wings provide a controllable aircraft while reducing drag by a factor of 40% compared to the comparator wings with conventional ailerons in a deflected position. IntroductionMorphing wings have been studied since the earliest days of heavier than air aviation, no doubt based on the commonplace observation that all birds continuously change the shapes of their wings during flight. The original Wright Flyer used "wing warping" for roll control -a fundamental form of wing morphing. There are many and varied ways that the wings of an aircraft can be altered in shape: the planform can be altered in size or span or sweep, section shapes can be altered, either to change lift magnitude and distribution or to gain vehicle control in pitch, roll, yaw, etc., wings can be twisted to alter effective angles of attack. Aeroelastic effects can be deliberately used to make geometry changes -so called aeroelastic tailoring. If allowance is made for the activation and deployment of conventional control surfaces, almost all aircraft lifting surfaces change shape in some way or other. One of the key recent drivers in morphing wing technologies has been the adoption of composite materials such as carbon fibre reinforced plastics. These have allowed for considerable tailoring of stiffness properties throughout the geometry of the wings so as to allow close control of the shape changes being achieved. In the wings developed here a careful matching of fibre and foam structural elements is used to govern the shapes taken up by the wing as it morphs.
