Small Unmanned Aerial Vehicle for vegetation monitoring
Trojánek, Tomáš ; Pejchar, Jan (referee) ; Dvořák, Petr (advisor)
The aim of this thesis was to select the most appropriate platforms for the fulfillment of required flight mission. The first part reviews available unmanned vehicles suitable for vegetation monitoring and includes both commercially available and self-made types. There are presented basic parameters, recommended equipment and tested configuration of each platform. The second part includes graphical comparison of all models in different categories and the most suitable platform has been selected on its basis. The model project which is based on the selected platform is presented in the final section.

Unmanned Aerial System design competition
Malinowski, Matěj ; Navrátil, Jan (referee) ; Pejchar, Jan (advisor)
Bakalářská práce se zabývá návrhem malého bezpilotního letounu určeného pro soutěž Air Cargo Challenge 2015. Práce je uspořádána dle postupu vývojových prací. Na prvotní koncepční návrh navazuje volba vhodného tvaru letounu a jeho profiláže. Následuje výpočet letových výkonů, maximální vzletové hmotnosti a centráže letounu. Poslední část práce se zabývá konstrukcí letounu a je provedena analýza závislosti užitečného zatížení na hustotě vzduchu.

Summary of Unmanned Aerial Vehicle
Haman, Tomáš ; Navrátil, Jan (referee) ; Dofek, Ivan (advisor)
The bachelor’s thesis deals with summary of unmanned aircraft. There is a reference to their historical development and possible uses for the selected aircraft are their technical parameters, including pictures. Thesis contains several types of UAV division according to various criteria. From these categories was selected a few representatives, which is followed by each of them a few characteristic data. The last part is a comparison of several aircrafts between two close categories.

Anti-Drone Perimeter Protection
Janík, Roman ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
Developement of drone technology brings opportunities for many fields of human activity, but simultaneously brings security threats. A need to effectively face these threats arises. In this work is described the problematics and state-of-the-art methods for object detection in a video captured by moving camera. A system for detecting and locating a drone or a flock of drones has been proposed. Algorithm for detection is based on convolutional neural network, specifically on SSD algorithm. The convolutional neural network was trained on self-made dataset. The system was implemented using OpenCV library with possible algorithm acceleration on GPU using OpenCL. Created solution was tested on video.

Structural optimization of 3D-printed Unmanned Aerial Vehicle
Sladký, Martin ; Šplíchal, Jan (referee) ; Löffelmann, František (advisor)
This master thesis deals with the design of the internal wing structure of 3D printed flying wing VUT 714. As a part of this work was performed a load calculation, static strenght test, comparative FEM analysis and subsequently topology optimization was performed. The outcome of this master thesis is a rational design of the wing internal structure based on the load calculation and knowledge of effect of this load on the structure.

Design of UAV hardware - mechanical and electrical subsystem
Kraus, David ; Hrbáček, Jan (referee) ; Krejsa, Jiří (advisor)
Main topic of this thesis is creation of platform for testing stabilization and control algorithms for UAV. For chosen suitable model plane was designed a structure of control and power electronics. Research of suitable algorithms was made and some of them were implemented. For this algorithms gains were designed, using simulation. The whole system was tested and validated in flight.

Design of a quadcopter model
Fiala, Jan ; Dosoudilová, Monika (referee) ; Hůlka, Tomáš (advisor)
The bachelor thesis deals with the creation and implementation of a quadcopter model. The first part summarizes the basic division of unmanned systems and the rules of legislation limiting their operation. Subsequently, the problematics of motion dynamic is discussed. The practical part first describes the selection of components used, their connection, and the creation of the quadcopter frame. The implemented control system and calibration are also described. In the final part, a flight test, price analysis, and rating in comparison with the competitive product are included. The conclusion contains an evaluation of the work, possible improvements, and reflections on the future use of the model.
