Performance possibilities of VTOL Unmanned Aerial Vehicle
Bartlová, Tereza ; Matějů, Jiří (referee) ; Juračka, Jaroslav (advisor)
Tato bakalářská práce popisuje a vyhodnocuje výkonnosti bezpilotních leteckých prostředků se svislým vzletem a přistáním pro transport nákladu. První část práce popisuje problém v oblasti transportu nákladu a současně nastiňuje možné řešení tohoto problému pomocí bezpilotního leteckého prostředku. Dále je definována mise, kterou bezpilotní prostředek musí splnit, a podle této mise specifikuje výkonnostní požadavky na bezpilotní prostředek. V této části je rovněž krátce zmíněna problematika legislativy provozování dronů v Evropské Unii. Druhá část této práce se zabývá analýzami, pomocí kterých jsou posouzeny výkonnostní požadavky a odhad potřebného výkonu bezpilotního letadla pro splnění požadované mise. První analýza je založená na datech o letových výkonech existujících bezpilotních i pilotních letadlech. Druhá analýza se zabývá vztahem mezi výkonem a celkovou plochou vrtulí. Další analýza se zabývá vztahem mezi maximální vzletovou hmotností a celkovou plochou vrtulí. Na závěr je prověřen vliv různých konfigurací letadla se svislým vzletem a přistáním na potřebný výkon a celkovou plochu vrtulí. Třetí část této práce je zpracován prvotní konfigurační návrh bezpilotního prostředku se svislým vzletem a přistáním, s tandemovým uspořádáním otáčivých křídel osazených pohonnými jednotkami. Nejprve je pro tuto konfiguraci vybrán počet vrtulí a jejich průměr a také odhadnut potřebný výkon. Poté je popsán prvotní návrh hybridní pohonné soustavy. Následně je provedena hmotnostní analýza prvotního konfiguračního návrhu bezpilotního prostředku s hybridním pohonem. Na závěr po zhodnocení výsledků všech analýz, je prezentován výkres hrubého konfiguračního návrhu bezpilotního prostředku.

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, problematics and state-of-the-art methods for object detection in a video captured by moving camera. Further I proposed a system for a drone or a flock of drones detection and localization. Algorithm for detection is based on convolutional neural network, specifically on SSD algorithm. I implemented the system with library OpenCV with possible acceleration of algorithm with GPU via OpenCL. I tested the created solution on both a video and a video camera output.

Safe Flight-Control of Drone Based on Sonar Measurements
Benkő, Krisztián ; Maršík, Lukáš (referee) ; Beran, Vítězslav (advisor)
Bachaleor's thesis describes design, implementation and testing of anti-crash system for safe flight-control of quadcopter. The system is implemented using ROS framework, where input data from sonars and keyboard are processed, calculation is then performed, output of which is controlling motors. Quadcopter is able to move safely in indoor environment. The emphasis was on speed of calculation and system testing. The quadcopter can be controlled by keyboard.

Acoustic Drone Detection Using Microphone Array
Múčka, Milan ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
This work deals with methods of acoustic localization for electrical multicopters using a microphone field composed of several microphones at a certain distance. The main methods of localization and detection using sound waves are explained in the paper. Next, the algorithms that implement these methods are designed. The results summarize the results of these algorithms together with experiments to verify their functionality.

Visualization Tool for a Drone Sqadron Commander in VR
Sladký, David ; Beran, Vítězslav (referee) ; Bambušek, Daniel (advisor)
The goal of this work is to design functions and user interface in VR for drone squadron commanders so they can faster and more effective command a drone mission. I implemented these function and user interface into already existing application DroCo for drone piloting with use of augmented virtuality. Because of this commander can create camera shortcuts in virtual environment, which can be teleported to or preview their feed and observe the course of current mission from different locations. At the end I also implemented user interface, that provides fast overview about all camera shortcuts and drones.

Drones and Their Use
Žanda, Martin ; Lang, Stanislav (referee) ; Šeda, Miloš (advisor)
The bachelor's thesis deals with drones and their areas of use. The aim of this thesis is capture a general and actual overview in area of these issues. This thesis is divided into 5 parts. The first part is devoted to legislation in area of civil aviation. The second part describes dynamics of movement and principle of control. The third part introduces individual components and sensors. In the following part, areas of use of drones are described. The last part is devoted to individual types of drones and their comparison.

The Development of Autonomous Unmanned Aircraft
Hamáček, Vojtěch ; Ligocki, Adam (referee) ; Jílek, Tomáš (advisor)
The aim of this thesis is to modify commercially produced drone DJI Matrice 100 and replace its original control unit by open source Pixhawk and its accessories. Subsequently, it deals with the selection of suitable open source firmware for Pixhawk and its configuration on the device. Another part is dedicated to the possibilities of using the Robotic Operating System (ROS) and its Mavros libraries on the onboard computer Raspberry Pi. By using Mavros, it examines the possibilities of drone flight control, both in the simulation environment and in the real environment.

Design of an Internal Combustion Engine for Small Autonomous Devices
Celý, Martin ; Beran, Martin (referee) ; Svída, David (advisor)
The work deals with the design and calculation of the basic components of a small combustion engine up to 5 cm3 for currently used smaller-sized vehicles. It includes an analysis and comparison of available drives for these devices and a more detailed analysis of the use of the combustion drive. In the next part, it proposes basic engine parameters and then design of individual basic dimensions of piston, connecting rod and crankshaft. The conclusion of the thesis is a basic strength calculation of critical points.

Monitoring Pedestrian by Drone
Dušek, Vladimír ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
This thesis is focused on monitoring people in a video footage captured by drone. People are detected by trained model of detector RetinaNet. A feature vector is extracted for each detected person using color histograms. Identification of people is realized by comparing their feature vectors with respect to their distance in the frame. In the end the trajectories of all people are visualized in a panorama image. Accuracy of the trained RetinaNet detector on difficult validation data is 58.6 %. Error rate is partially reduced by the way of algorithm design for trajectory visualisation. It's not necessary to successfully detect person on every frame for correct visualization of its trajectories. At the same time, static objects which are detected as person but are not moving are not consider as people and are not visualized at all. There is a lot of algorithms dealing with people detection however only a few approaches are focused on detection people from an aerial footage.
