The design of a quadrocopter for food delivery
Gryc, Matěj ; Čípek, Pavel (referee) ; Skurka, Šimon (advisor)
Online delivery of hot food to the customer's home has become standard. However, as a result of the covid-19 pandemic, methods of safe delivery that do not require interpersonal contact are now being sought. The use of drones, which are already being used in some countries to transport goods and materials, seems promising. This bachelor thesis deals with the design and assembly of a quadcopter designed for food delivery. First, the frame was designed, which was largely fabricated using 3D printing. Based on calculations, the electronics including batteries and motors were selected. Then the mechanism by which the food transport will be mediated was designed. Once constructed, the functionality of the quadcopter and delivery mechanism was tested. Finally, the design was evaluated and possible improvements were mentioned.

Drone position stabilization methods using image data
Koukal, Ondřej ; Raichl, Petr (referee) ; Janoušek, Jiří (advisor)
This bachelor’s thesis focuses on the design of an unmanned aircraft stabilization system. The purpose of this system is to determine the exact position of the unmanned aircraft in space based on image data from two cameras in real time. The theoretical part describes the image processing methods and the algorithm for determining the position of the unmanned aircraft. The practical part describes the implementation and testing of the system.

Server for Data Communication between Drones
Herrgott, Jiří ; Materna, Zdeněk (referee) ; Bambušek, Daniel (advisor)
This master thesis focuses on the transfer of flight and multimedia data between operators and drones for better real-time mission planning and coordination. A program has been developed that primarily provides these services. The work emphasizes robustness, reusability and extensibility, allowing the creation of modules such as detection or 3D reconstruction from the transmitted data. In addition, modules for flight and multimedia data storage and a module for vehicle detection from shared images have been developed in this work. Experiments were performed to evaluate the response time, the required computational resources and the used connection bandwidth.

Legal regulation of unmanned aircraft
Bušek, Rostislav ; Vedral, Josef (advisor) ; Staša, Josef (referee)
Legal regulation of unmanned aircraft Abstract This thesis deals with the legal regulation of drones with emphasis on the European legal framework and the administrative practice of the Civil Aviation Authority. The aim of the thesis is to provide an explanation of the different terms such as unmanned aircraft and unmanned system, to define the different classes of unmanned systems and to categorize the different types of operation. The thesis is divided into eight chapters. The first chapter is devoted to the history and allows to interpret the current legislation in the light of its development. The second chapter describes the three-level legal framework, which consists of international law, European Union law and national law. In this chapter I focus on the international organizations operating in the civil aviation sector and their common objectives. The third chapter details the basic concepts of unmanned aviation and compares their definitions in different documents. The fourth chapter focuses on the production, marketing and classes of unmanned systems. It also discusses the obligations of manufacturers, importers and distributors of unmanned systems. The fifth chapter discusses the operation of unmanned systems and the categorisation of different operations with an emphasis on their comparison. In...

Konstrukční návrh bezpilotního letadla pro aplikaci v zemědělství
Frydrych, Jan
The diploma thesis deals with structural design of unmanned aircraft for application in agriculture. Thesis describes precision agriculture, agricultural machines, unmanned aircrafts, and technology of 3D printing. An analysis of these topics is performed, and it is also mentioned the legislation for using unmanned drone in the Czech Republic. In the second part the diploma thesis is focusing on structural design of unmanned aircraft and its individual parts. The structural design is extended by a draft of docking station which also works for charging the aircraft. The production technology was chosen 3D printing using PET-G material. In the end of the thesis, the process of 3D printing and mechanical testing of ASA, PET-G and rPET-G materials is described.

Design of a small hydroelectric power plant on the Askistskali River in Georgia
Mitrega, Stanislav ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
The main objective of the thesis is to develop a project for a small hydroelectric power plant on the Askistskali River in Georgia. The thesis includes a geodetic survey using drone photogrammetry and a visit of the site of interest. The thesis presents the documents supplied by Stream Ltd. and describes the procedure of geodetic surveying using a drone. In the next part, the new design of all the structures is described and the results of the economic analysis are presented. It is followed by the calculations part, which describe the design procedure for each structure. At the very end of the thesis, a photographic documentation of the area of interest is attached. Based on the economic analysis, the project was assessed as a profitable investment opportunity.

Modern methods of visualization and interpretation of radiation quantities measured by a drone.
ŘEZÁČ, Miroslav
The bachelor thesis focuses on modern methods of visualization and interpretation of radiation quantities measured by a drone. It mainly deals with the measurement of radiation quantities using a drone, their subsequent correct interpretation and subsequent appropriate visualization. In the theoretical part, I conducted a literature search on the state of measurement of radiation quantities in our country and in the world. In the next part, I performed an analysis of the literature in the field of radiation protection with a focus on monitoring radiation quantities using a drone. Here I describe the basic radiation quantities and various possibilities of the interaction of radiation with matter. Furthermore, various types of detectors and detection devices that I used for measurement. At the end of the theoretical part, I focused on drones. It describes basic information about drones, their history, aviation regulations needed for their use. I also described a drone and a system that was used to measure radiation quantities. In the practical part I focus on the experiment with a point emitter, where I apply the knowledge from the theoretical part. I also describe walk-through measurement and measurement of radiation quantities using a drone. The next chapter focused on the interpretation of data and the use of various methods. In the last chapter I describe the possibilities of visualization of measured data, the use of the QGIS program for visualization in map data and other possibilities of data visualization with other tools. In the end, I focused on the overall evaluation of the results examined in the bachelor's thesis and their subsequent application in other measurements.

Map of Kopicův statek and its surroundings (Bohemian Paradise, Czechia)
Peterková, Lucie ; Lysák, Jakub (advisor) ; Bayer, Tomáš (referee)
The aim of the bachelor thesis is to create a large-scale map with touristic content of the surroundings of Kopic's farm located in the village of Kacanovy in the Bohemian Paradise. The thesis is mainly focused on the representation of sandstone rocks by the contour method and artistic reliefs on them created by Vojtěch Kopic in the last century. The emphasis is on the use of data collected by drones (lidar, optical images). The existing available map documentation of the area of interest was also evaluated, with the result that the map produced exceeds all of them in quality and detail. Detailed mapping of the objects was carried out by means of a field survey using ArcGIS Field Maps. The final map, that obeys cartographic principles, was created in ArcGIS Pro software. The large-scale (1 : 670) map of the site is in the form of a paper map in A3 format. It is probably the first map showing the surroundings of the Kopic farm in such detail and at the same time documenting the created rock gallery, which is part of the monument heritage of the Kopic farm. Key words: digital cliff drawing, large-scale map, sandstone relief, lidar, drone
