“…Unmanned aerial vehicles (UAVs) have gradually become part of everyday life. They are widely used in various branches of industry, for example, for monitoring and mapping terrain [1][2][3][4][5] or magnetic fields (either outdoors or indoors measurement) where the cleanliness of the environment is taken into account [6,7]. In addition, they also play an important role in the field of search and rescue [8,9] and in the monitoring of public spaces [10,11].…”

This article deals with quadcopter modeling using a system for the measurement of unmanned aerial vehicle (UAV) parameters. UAVs are often equipped with various measurement devices and equipment for measurement, which significantly affects their weight. The currently available technical solutions and inventions do not allow corrections to be made to the on-board control electronics settings without the need to perform a test flight, or without the need to create complex and time-consuming mathematical models of the unmanned aerial vehicle; therefore, it is desirable to create a new method for modeling the characteristics of an UAV based on static laboratory measurements. The goal of this paper is to create a dynamic model of a quadcopter that will be adapted to a system for measuring UAV parameters, specifically the thrust of individual motors, which will be the next step to creating a new method for modeling UAV characteristics. This method can be used in the future for tuning flight control algorithms, based on static laboratory measurements.

“…The UAVs are widely used nowadays. It is possible to use them for wildlife monitoring [1][2][3], rescue operations [4,5], property inspection [6], monitoring and mapping [7][8][9], magnetic field mapping [10,11], monitoring in public spaces [12,13] or, at present, the import of medicines [14,15], disinfecting of public spaces or even monitoring people's temperatures [16]. However, in such uses, it is necessary to consider the increased weight of these UAVs when they are equipped with various devices [17][18][19][20][21], or they may be supplemented by different systems in the future [22].…”

This article deals with the design and creation of a tensometric measuring system to measure the parameters of an unmanned aerial vehicle (UAV) of the quadcopter type. The system was designed to measure the total UAV thrust and the thrust of its individual motors. The distribution of forces from the UAV motors and their transmission to the sensors was ensured by a specially designed construction, for which the mechanical stresses were simulated and analysed for different modes of the UAV flight. The thrust measurement was performed by four pairs of strain gauges. A measurement system designed in this way and the measured parameters of the UAV can be used for tuning the flight control algorithms applied in the autopilot.

“…The idea of magnetic field mapping in the indoor environment, which is presented in this article, has its origin in the ongoing continuous research and development of magnetic sensors and their applications, which also involves the concept of a magnetometer for UAV geophysical survey [ 48 ]. In combination with the knowledge obtained during the research in the area of analysis of small UAV electromagnetic images in a very low frequency range [ 49 ] together with the performed magnetic field measurements related to safety [ 50 , 51 ], we proposed the original idea that small UAVs could be used for quick magnetic field mapping and evaluation, not only outdoors, but thanks to the ultrasonic-aided navigation, could be used in the indoor environment as well.…”

Unmanned aerial vehicles (UAVs) are used nowadays in a wide range of applications, including monitoring, mapping, or surveying tasks, involving magnetic field mapping, mainly for geological and geophysical purposes. However, thanks to the integration of ultrasound-aided navigation used for indoor UAV flight planning and development in sensorics, the acquired magnetic field images can be further used, for example, to enhance indoor UAV navigation based on the physical quantities of the image or for the identification of risk areas in manufacturing or industrial halls, where workers can be exposed to high values of electromagnetic fields. The knowledge of the spatial distribution of magnetic fields can also provide valuable information from the perspective of the technical cleanliness. This paper presents results achieved with the original fluxgate magnetometer developed and specially modified for integration on the UAV. Since the magnetometer had a wider frequency range of measurement, up to 250 Hz, the DC (Direct Current) magnetic field and low frequency industrial components could be evaluated. From the obtained data, 3D magnetic field images using spline interpolation algorithms written in the Python programming language were created. The visualization of the measured magnetic field in the 3D plots offer an innovative view of the spatial distribution of the magnetic field in the area of interest.
