“…The authors reported finding only five feasible nondominated solutions. 14) Jagdale et al [65] applied a MOEA for the conceptual multidisciplinary design of a bendable UAV wing. Such types of wings, constructed from composite materials, have two conflicting structural requirements: first, the complete wing must be able to be folded for its storage in a container and, second, it must be stiff enough to withstand the aerodynamic loads during flight operation, in order to avoid buckling, due to an excessive material strength and large deformation.…”

Nowadays, the solution of multiobjective optimization problems in aeronautical and aerospace engineering has become a standard practice. These two fields offer highly complex search spaces with different sources of difficulty, which are amenable to the use of alternative search techniques such as metaheuristics, since they require little domain information to operate. From the several metaheuristics available, multiobjective evolutionary algorithms (MOEAs) have become particularly popular, mainly because of their availability, ease of use, and flexibility. This paper presents a taxonomy and a comprehensive review of applications of MOEAs in aeronautical and aerospace design problems. The review includes both the characteristics of the specific MOEA adopted in each case, as well as the features of the problems being solved with them. The advantages and disadvantages of each type of approach are also briefly addressed. We also provide a set of general guidelines for using and designing MOEAs for aeronautical and aerospace engineering problems. In the final part of the paper, we provide some potential paths for future research, which we consider promising within this area.

“…the eBeeä by senseFly or the Spreading Wings series from DJI), which are bulky, prone to failure in collisions, difficult to scale and require complex and error-prone manual operations from the user to be deployed and stowed. Foldable drones made out of continuous elastic structures are easier to operate, but cannot undergo considerable reduction of size because sharp folds are constrained by the material's strain limit [7]. Origami based manufacturing partially overcomes the aforementioned limitations, allowing to produce scalable and complex folding patterns in lightweight structures [8] [9].…”

Abstract-Flying robots are rapidly becoming an essential tool in search and rescue missions because they can rapidly gather information from inaccessible or unsafe locations, thus increasing safety and rapidity of interventions. With this aim, we present a pocket sized foldable quadcopter equipped with a camera. The drone is a portable and rugged "flying-eye" that aims to extend or move the field of view of the rescuer for situational awareness and safe reconnaissance. The quadcopter can be packaged for transportation by folding its arms and it self-deploys in a glimpse before usage. Its compliant foldable arms make it rugged, reducing the risk of failure after collisions. The drone is remotely operated and it can stream sound, thermal and visual images in real time to rescuers. The prototype of the foldable quadcopter is experimentally characterized and assessed in preliminary field tests. I. INTRODUCTIONDrones are becoming ubiquitous in the daily life and their socio-economic impact is constantly increasing [1]. In the field of search and rescue, we are witnessing the growth of a wide spectrum of applications, such as mapping [2], inspection [3] and multi-modal operations [4], where unmanned aerial vehicles are leveraged to increase safety, productivity and rapidity of intervention, while minimizing operational costs.While the challenges surrounding perception and control are frequently cited as being key areas for research [1], other important aspects are how to make such robots easily transportable, quick to deploy and robust against collisions. Several applications exist where a resilient, readily available drone would be a game changer. For example, in search and rescue missions where damage relief is subordinate to the rapidity of intervention [5], and where flights in cluttered environments with high probability of collisions are a commonplace [3]. To tackle these challenges, we are envisaging a new class of sturdy and portable drones, which function as a personal "flying eye" that is readily airborne from users' hand as soon as it is taken out from a pocket or a backpack.Leveraging the miniaturization of electro-mechanical components, drones that fit the palm of a hand are now commonplace. However, since lift is increasing with the size of the drone, smaller drones have significantly reduced time of flight and payload [1]. This drawback could be addressed by incorporating foldable structures [6] in comparatively larger drone with suitable payload that can be stored and transported in a small volume. Most of the existing foldable drones rely on multi-joint folding mechanisms (e.g. the The authors are with the Laboratory of Intelligent Systems
