    A Low-Cost UAV Design for Surveillance Purposes in Swarm Systems
    (Institute of Electrical and Electronics Engineers Inc., 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    This study focuses on a low-cost UAV design for a swarm UAV system to be used in reconnaissance and surveillance applications. The individual UAV, which will form the swarm and serve in this context, is designed in accordance with the swarm behaviors and requirements such as autonomous behavior, formation and coordination. Within the scope of the planned flight missions, the necessary communication architectures were emphasized by considering the communication between the ground control station and other swarm members. The most cost-effective equipment for fundamental tasks such as flight control, swarm intercommunication, object detection has been studied, and individual swarm members are equipped in line with these requirements and limitations. The problem of consistent sharing of data obtained during the flight mission has been examined in detail and appropriate solutions have been produced with proper communication and data transfer protocols. A low-cost solution has been obtained for aerial surveillance applications of the swarm UAV system, which can provide direct point-to-point communication through selected equipment and network message transmission during flight. © 2023 IEEE.

    Adapting Swarm Intelligence to a Fixed Wing Unmanned Combat Aerial Vehicle Platform
    (Springer Science and Business Media Deutschland GmbH, 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    The majority of the swarm UAV studies focus on a single aspect, only investigating the stages such as formation development, path planning, or target tracking for a swarm currently in mission flight. Besides, the dynamic coordination and operation of the system based on the new commands that can be transmitted to the swarm during the mission are not taken into account; that is, the input of the ground resources is often ignored. In this study, all stages of a swarm of unmanned combat aerial vehicles (UCAV), from take-off to the end of the mission, are detailed in a single holistic framework, including communication with the ground station and intercommunication between swarm members. The designed solution is a platform that will enable the swarm structure to prevail by developing alternative strategies and tactics against existing manned or unmanned air, land, and sea platforms. In this context, operational algorithms have been developed for fixed-wing, fully autonomous controlled UCAVs, which can successfully detect in-sight and beyond-sight targets for a desired period of time, and can communicate seamlessly with ground stations. Furthermore, dynamic swarm-type algorithms have been developed in order to fulfill the desired task in the event of the loss of any UCAV during the mission, to replace the lost vehicle with a new vehicle, and to communicate directly with the UCAVs in the swarm. As a result of adapting swarm intelligence to the UCAV platform, all individuals in the swarm perform tasks such as taking off in formation, adding or removing new individuals to the swarm, and formation protection. Moreover, they have the ability to change direction in a swarm, change formation, split or merge, navigate, ascend and descend, and simultaneous/sequential auto-landing as a swarm. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

    An Avionics System for Light-Weight Multi-Rotor Unmanned Aerial Vehicles
    (Institute of Electrical and Electronics Engineers Inc., 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    Small and light unmanned aerial vehicles (UAV) are increasingly used because of a wide variety of advantages they provide. These vehicles, which are especially preferred in applications such as 3D mapping, atmospheric measurements, and intelligent transportation systems, are at the heart of many researches due to their easy accessibility and ease of use. Moreover, the importance of these vehicles becomes even more evident in situations and locations where human intervention is not possible. However, their ability to perform these tasks in an ideal way reveals the necessity of a good avionics system. In particular, when it comes to autonomous flight, this becomes even more important. A properly designed avionics system is the first step for a UAV in flight to successfully accomplish its mission. In other words, the performance of the UAV is directly related to the functionality of the avionics. In this study, an avionics system is designed for a small and light-weight UAV, through careful consideration of the systems and components needed for autonomous flight, navigation, and communication. Within the scope of application areas, the system requirements for the UAV have been determined, and a design has been made in accordance with its capacity. © 2023 IEEE.

    Drone-Assisted Path Planning Optimization for Mobile Robots in Dynamic Scenarios
    (Institute of Electrical and Electronics Engineers Inc., 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    In this study, the seamless integration of drones into military distribution operations is facilitated by coordinating the movements of mobile robots in both time and space. The approach consists of two key stages: first, the development of an iterative exact solution methodology to establish the optimal route for the mobile robot, and second, the optimization of the drone's route through a mixed integer linear programming model. The performance of this approach is assessed by initiating the process with the shortest route for the mobile robot and iteratively refining assignment and routing decisions. The primary objective of this study is to enhance the simultaneous deployment of drones and mobile robots within military zones. By doing so, the aim is to harness the full potential of unmanned aerial vehicles (UAVs) more efficiently and lay a solid foundation for future technological advancements. © 2023 IEEE.

    Gaining Swarm Behavior through Establishing a Control System and Communication Network on Unmanned Aerial Vehicles
    (Ieee, 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    The aviation industry has been disrupted to a great extent, with unmanned aerial vehicles (UAVs) attracting great interest in both industry and academia in recent years. As technology continues to evolve, disruption has only continued to increase in size as it finds its place in a wide and diverse field covering both military and domestic fields. With indigenous practices such as search and rescue missions during disasters, environmental monitoring and surveillance, agriculture and farming, this disruption has shifted to a specialized technology, swarm UAVs. Communication is a critical component in swarm systems with the potential to distribute missions and coordinate the operation of many UAVs without operator intervention. In this study, a swarm architecture is proposed that will allow higher swarm autonomy and reliability by providing both reliable communication between swarm systems and the ground station, and communication between individual UAVs. The development of swarm UAVs with autonomous coordination capability with wireless ad hoc networks, an attractive solution for inter-UAV communication, is at the heart of improving the utility of UAV swarms. During the realization of this, the integrated communication architecture of the swarm UAVs, which combines both the long-range architectures offered by 900 MHz-based radios and the short-range architectures offered by 802.11-based ad-hoc networks, coexists. All these systems are implemented using the robot operating system (ROS), which allows it to be easily integrated into the capabilities of any distributed application.

    Post-Disaster Area Monitoring with Swarm UAV Systems for Effective Search and Rescue
    (Ieee, 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    Although the use of unmanned aerial vehicles (UAVs) in reconnaissance and monitoring applications is quite common, there are cases where these vehicles are insufficient due to some structural and design disadvantages. These vehicles, which have advanced capabilities, cannot perform some key tasks due to constraints such as limited flight time, active communication range, and low payload capacity. At this point, the swarm unmanned system approach has the ability to overcome such problems, and the intelligence to achieve more. Thus, more can be accomplished in a short amount of time with swarm systems than a single UAV can do in a flight mission. In this study, a post- disaster area scanning with a swarm UAV systems is discussed. By sharing tasks with individual UAVs in the swarm, it is aimed to scan a large area in a shorter time interval, and to increase the efficiency of post-disaster search and rescue efforts. In this context, it has been ensured that the monitoring and detection tasks, performed by distributing the field scanning process to the swarm individuals, are carried out more effectively and quickly. In addition, an effective internal communication mechanism has been developed for the proper coordination of UAVs during the mission, thus preventing possible collisions and false area scanning.

    Surveillance, Reconnaissance and Detection Services for Disaster Operations of IoT-Based eVTOL UAVs with Swarm Intelligence
    (Institute of Electrical and Electronics Engineers Inc., 2023) Bakirci, Murat; Ozer, Muhammed Mirac
    This study offers a swarm system solution of a fully autonomous electric vertical take-off and landing (eVTOL) rotary wing unmanned aerial vehicles (UAV) providing optimum level of telecommunication service, communication and formation skills, casualty detection, and transportation in a natural disaster scenario in a region with areas where GPS data is corrupted. It is ensured that the swarm UAV system, which follows the guide UAV in the disaster area by taking different formations and maintains these formations in case of GPS interruptions, makes the necessary observations through embedded cameras. Moreover, in line with the decisions to be made by the system, it provides telecommunication services to as many users as possible for as long as possible with its mobile base stations and transporting the injured to suitable regions. In order to provide information to users with smart devices that support IoT, necessary information and services can be transferred to users via connector UAVs by establishing a connection between the ground station and swarm UAVs. A secure communication network is provided in response to security risks that may occur while the UAVs in the swarm communicate throughout the mission. In addition to the system working together in different formations and broken GPS situations throughout the mission, communication limits are reduced in the insecure area between the swarm and the connector UAV, where communication cannot be achieved, and the unsafe interval is minimized. © 2023 IEEE.
