Unmanned aerial vehicles (UAVs) represent technological developments used for precision agriculture. They provide high-resolution images taken from crops and when specific indices are applied, useful outputs for farm management decision-making are produced. The current paper provides a literature review on the use of UAVs in agriculture and specific applications are presented.

The use of Unmanned Aerial Vehicles (UAVs) with Unmanned Ground Vehicles (UGVs) allows for cooperation, coordination, and tight or loose collaboration related to multiple missions. UAVs can provide a global perspective of the surrounding environment, obstacles, and possible threats, broadcasting goals, sub-goals and alterations to the overall mission of the swarm. Further, the deployment of UAV...

Unmanned Aerial Vehicles (UAV) are being increasingly used in growing number of applications. The use of single vehicle is often not enough due to various limitations, such as available power or sensors installed. Therefore the UAVs are formed into cooperative teams that operate as the distributed processing system realizing the given mission with one or more objectives (tasks) defined. The key...

Advances in electronics and software are allowing the rapid development of small unmanned aerial vehicles (UAVs), capable of performing autonomous coordinated actions. Developments in the area of lithium polymer batteries and carbon fiber-reinforce plastic materials let UAVs become an aerial platform, that can be equipped with a variety of sensors such as cameras. Furthermore, it is also possib...

Over recent years, research into Unmanned Aerial Vehicles (UAVs) has increased substantially. However, if autonomous flight of these vehicles is to become feasible in the near future, a collision avoidance scheme must be developed to ensure airspace safety. In this paper, we propose a novel artificial potential field approach to this problem, which, combined with a powerful priority-based syste...

Precision agriculture is becoming very important in improving food security. Unmanned Aerial Vehicles (UAVs) have higher possibilities in this way, improving real time data gathered with aerial sensors. Fuzzy techniques have proved to be highly effective in managing vagueness and ambiguity. The unmanned helicopters are highly valuable due to the level of maneuverability that they possess. We be...

This paper presents an effective methodology for the simplified representation of the kinematics and the horizontal flight control of Unmanned Aerial Vehicles (UAVs). A real UAV has been used as a model in this project. The flight behavior of the UAV has been modeled in terms of simple analytic relationships, which proved very helpful in representing UAV’s actual horizontal motion. A fuzzy cont...

A technique to obtain high resolution atmospheric data using small mobile sensors is presented. A fluid based control scheme using smoothed particle hydrodynamics (SPH) is implemented to perform field measurements in a leaderfollower arrangement for a team of unmanned aerial vehicles (UAVs) equipped with environmental sensors. A virtual leader is created by using a reduced density SPH particle ...

a r t i c l e i n f o For many applications such as environmental monitoring in the aftermath of a natural disaster and mountain search-and-rescue, swarms of autonomous Unmanned Aerial Vehicles (UAVs) have the potential to provide a highly versatile and often relatively inexpensive sensing platform. Their ability to operate as an 'eye-in-the-sky', processing and relaying real-time colour imager...
