Autonomous CPSs are often required to handle uncertainties and self-manage the system operation in response to problems and increasing risk in the operating paradigm. This risk may arise due to distribution shifts, environmental context, or failure of software or hardware components. Traditional techniques for risk assessment focus on design-time t...

In the last decade, the rate of the industrial usage of fixed-wing and blended wing aircraft has increased. A 1–2-km ² area can be surveyed by such a drone within 30 to 60 minutes, without any special infrastructure, and this can be repeated at any time. This provides an opportunity to conduct automatized surveys and time series data testing, which...
Article
Full-text available
In case of surveys conducted at open-pit mines, currently classical surveying methods are applied, or rather they provide assistance as supplements after the appearance of drone technology. Using a fixed-wing or a blended wing body UAV, the surveyscan even reach an accuracy below the value of 1m, by means of ground control points. During the survey...

Photogrammetry based 3D model creation provides a new opportunty to survey and to evaluate natural and arificial surface formations. The photos needed for 3D model building can be taken using fixed wing aircraft or multicopters. These machines are more economical and are capable of more precise route tracking than big machines operated by human per...

In the last decade modern agriculture used significant resources for automated evaluation. Game damage and crop evaluation and prediction are the main focus of the precision agriculture. At John von Neumann Faculty of Informatics, Óbuda University, Hungary, researchers together with agricultural experts are developing automated evaluation methods f...
Article
The AERObot is a special ARM microcontroller-based autopilot for small and medium size UAVs(1) developed at Obuda Universtiy for research purposes. The aim of the research was to create a generic autopilot which is capable of controlling different design, weight and structure airframes without any complex parameter or model recalculation as usual f...
Conference Paper

This paper presents a complete solution for unmanned 3D aerial image matching. There are many application which needs precise and up to date 2D and 3D maps, georeferred maps, digital elevation models (DEM). The common solution is a use of a manned airplane and capture multiple high resolution pictures, than match them with a third party geographic...
Article

The aim of the research was to develop an Unmanned Aerial Vehicle (UAV) hardware and software which can control a small size UAV (with 1-10 kg takeoff weight) from takeoff to landing. The research was based on AERObot V5 autopilot, developed and tested previously by us. AERObot can control a chosen aerial vehicle on a predefined route and altitude...

AirGuardian is a complex of an Unmanned Aerial Vehicle and ground station UAV hardware and software systems which has been developed at Obuda University. The hardware and software of the autopilot (AERObot), the antenna tracker station and the ground control station were simultaneously created resulting in the optimal cooperation of the modules. T...
Conference Paper
Unmanned aerial vehicles from micro to large scale are a common research topic in the latest years. Small size (under 3 m wingspan and between 1-15 kg all up weight) UAVs and the autopilots usually have no redundancy and have been not prepared for emergency situations. Loss of control, power management, engine or a faulty sensor could cause serious...
Conference Paper
The AERObot autopilot for small and medium size unmanned aerial vehicles (UAVs) developed at Óbuda Universtiy has multiple control systems. It is possible to switch between the control systems even during in flight. The purpose of the current research was to examine the applicability of full fuzzy flight control (takeoff, cruise and land) in unmann...

Full-text available
The tuning of the navigation controllers for an Unmanned Aerial Vehicle (UAV) is a relatively long process. The reason is that the controllers can be tuned during test flights only. This tuning must be started in calm weather then continue in higher and higher wind, while the UAV reaches its given weather limits. The aim of this research is to deve...
Article
Parameters of the onboard electronics of a small sized (0.5-3m) and light weight (0.5-5kg) UAV is highly limited. Usually there is only a low powered, narrow bandwidth 2.4 GHz radio modem (e.g. XBee or XStream) for the communication. The useful range of these modules is only 1-2 km. Over that distance, the noise of the channel is very high. There i...
Conference Paper
In unmanned aerial vehicle operations as well as in aviation the airflow direction and speed plays a major role. The wind speed may limit the use of aircraft, and determines the direction of the takeoff and landing. In the case of small size UAVs (0.5 - 4 m wingspan, 0.5 - 10 kg takeoff weight) the strength and the direction of the wind is quite im...
Article
There are many ways to control an unmanned aerial vehicle. Not all of them can be applied to all category. There is often need to control a small size (0.5-25 kg) unmanned aerial vehicle via direct control within sight during the operation. This mode is practically the same as controlling a radio controlled (RC) model aircraft. The significant diff...
