“…Because of this, they are a far more effective alternative for topographic mapping of huge areas and can travel farther than multi-rotor drones. Compared to multirotor drones, it has the potential to fly for a longer period of time [32]. Drones in the built environment, particularly in the construction business, have a variety of applications [33].…”

An unmanned aerial vehicle (UAV), also called a drone, has been gaining attention globally to solve different tasks. The aim of this study is to assess the awareness and level of adoption of these types of drones by building professionals and the factors limiting their use in the built environment. The study was carried out in Lagos State, in the southwestern part of Nigeria. Data for this research were collected from primary and secondary data sources. Primary data was obtained by administering a questionnaire to the selected building industry professionals, and the collected data were analyzed using both descriptive and inferential statistical techniques. The results showed that structure inspection and photography are the most rated features of drones in addressing built environment tasks, with a mean score (MS) of 4.50, and security surveillance (MS = 3.86) is the least important feature. The level of adoption of drones in addressing built environment tasks was assessed among the professionals, and the results showed that the practice of an emergency response plan and a health and safety plan to reduce the risk of harm and ensure safety on site is considered to be the most important task. The study found that the fixed-wing hybrid drone with an MS of 1.97 is the most commonly used drone type. Lastly, the study showed that lack of public awareness (MS = 4.81) is rated as the most significant factor that limits its use. Few professionals have practically used drones to solve tasks faced in the building industry. Thus, there is a need to further sensitize built environment professionals to the benefits associated with its wider adoption and applications. Also, the importance of drones and their associated managerial and practical implications in solving relevant built environment tasks can be initiated by deepening their relevance in the curriculum of building industry programs at the professional and academic levels.

The proliferation of Unmanned Aerial Vehicle (UAV) networks is increasing, driven by their capacity to deliver automated services tailored to the varied demands of numerous smart city applications. Trust, security, and privacy remain paramount in the public domain. Traditional centralized network designs fall short of ensuring device authentication, data integrity, and privacy within UAV networks’ highly dynamic and adaptable environments. Decentralized reputation systems emerge as a promising solution to enhance the reliability and trustworthiness of data and communications within these networks while safeguarding UAV security. This paper presents an exhaustive survey of trust and reputation systems, exploring existing frameworks and proposed innovations alongside their inherent challenges. It highlights the crucial role of reputation systems in strengthening trust, security, and privacy throughout these networks and discusses various strategies to mitigate existing vulnerabilities. As a useful resource for researchers and practitioners seeking to advance the state of the art in UAV network security, we hope this survey will spark further community discussion and stimulate innovative ideas in this burgeoning field.

“…This enabled PULSAR to perform challenging tasks like avoiding highspeed dynamic obstacles, which are possible only in quadrotor UAVs (46,47) to date. For existing self-rotation UAVs (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33) and other underactuated UAVs with fewer than four propellers (40,(48)(49)(50)(51)(52), the main focuses were on design concept, vehicle configuration, and flying feasibility, whereas agility and the ability to avoid dynamic obstacles were not considered or demonstrated. Only the dSAW proposed in (28) demonstrated an agile motion that involved only unpowered diving.…”

A self-rotating, single-actuated UAV with extended sensor field of view for autonomous navigation

Uncrewed aerial vehicles (UAVs) rely heavily on visual sensors to perceive obstacles and explore environments. Current UAVs are limited in both perception capability and task efficiency because of a small sensor field of view (FoV). One solution could be to leverage self-rotation in UAVs to extend the sensor FoV without consuming extra power. This natural mechanism, induced by the counter-torque of the UAV motor, has rarely been exploited by existing autonomous UAVs because of the difficulties in design and control due to highly coupled and nonlinear dynamics and the challenges in navigation brought by the high-rate self-rotation. Here, we present powered-flying ultra-underactuated LiDAR (light detection and ranging) sensing aerial robot (PULSAR), an agile and self-rotating UAV whose three-dimensional position is fully controlled by actuating only one motor to obtain the required thrust and moment. The use of a single actuator effectively reduces the energy loss in powered flights. Consequently, PULSAR consumes 26.7% less power than the benchmarked quadrotor with the same total propeller disk area and avionic payloads while retaining a good level of agility. Augmented by an onboard LiDAR sensor, PULSAR can perform autonomous navigation in unknown environments and detect both static and dynamic obstacles in panoramic views without any external instruments. We report the experiments of PULSAR in environment exploration and multidirectional dynamic obstacle avoidance with the extended FoV via self-rotation, which could lead to increased perception capability, task efficiency, and flight safety.
