Biometric 2D face recognition from camera system placed on a quadrocopter
Mikundová, Lea ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
This Bc. thesis is devoted to face recognization from camera system placed on a quadrocopter. The teoretical part is about the most used methods for detection and face recognition and their comparison. The next part is about motion capturing from quadrocopter. Practical part of thesis is devoted to implementation of algorithms for face detection and recognization by OpenCV library and evaluation of algorithm in respect to distance and angle of quadrocopter due to captured person.

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.

Quadcopter design and utilization with the use of Arduino Due
Majer, Dominik ; Olejár, Adam (referee) ; Krajsa, Ondřej (advisor)
This bachelor thesis is about design of usable prototype of quadrocopter using standard RC components, with Arduino Due control unit and gyroscope with MPU6050. Main goal is the fully functional prototype with feature for reduction of barriers collision possibility, using ultrasonic sensors. The first part of thesis is the description of each component and their cooperation. The second part describes final solution, flowchart, source code with problems arisen. Source code is written in programming language Arduino, which is based on Wiring language. Further the brief analysis of autonomous flight of quadrocopter is done, particulary with GPS module and possible brief design of this idea. Finally the analysis of basic options of telemetry transmission, such as GSM module, wi-fi, bluetooth, are analysed.

Quadrotor altitude stabilization
Ligocki, Adam ; Kříž, Vlastimil (referee) ; Gábrlík, Petr (advisor)
The aim of this thesis is to design and implement a vertical stabilization for drone developed at the Department of Control and Instrumentation of the Faculty of Electrical Engineering and Communication. Work gradually deals with summary of already existing solutions of already existing projects, analysis of individual sensors possible to be applied in this project and evaluate their pros and cons for measuring the flight altitude. It also deals with the mathematical apparatus suitable for processing altitude data and the design and implementation of the controller for the movement of the drone in the vertical axis. The conclusion summarizes the results achieved on real hardware.

User Interface for Autopilot of Quadcopter
Klein, Ondřej ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
Bachelor's thesis describes the design and implementation of user interface for autopilot of quadcopter. Controlling the quadcopter is done via tablet computer. It provides manual and semi-autonomous mode and the option to control quadcopter by virtual joysticks or device movement. Part of the thesis is detailed analysis of quadcopter's abilities and description of existing solutions, which serves as a basis for the design of the application. The final program is tested and the results are evaluated.

Quadrocopter Navigation and Control
Doležal, Karel ; Orság, Filip (referee) ; Herman, David (advisor)
This paper focuses on autonomous navigation of AR.Drone quadrocopter in outdoor environment. The goal is to follow a specified route and land autonomously on a platform placed at the destination. Firstly, the AR.Drone platform, its development kit and sensor extension with GPS and a magnetic compass are described. Then, the navigation architecture of a control program is presented describing important blocks and its' individual tactics. Localization of the landing platform is based on its color. The video is also used to detect nearby obstacles using optical flow calculation suppressing the quadrocopter movements and to avoid the greater changes in the image. The control program implementation is then tested in real environment and the results are presented.

Anti-crash System for Quadcopter with set of sonars
Hrazdil, Radim ; Musil, Petr (referee) ; Beran, Vítězslav (advisor)
This bachelor’s thesis is focused on installing ultrasonic sonars on a quadcopter, connecting them to the Arduino Micro microcontroller and implementing a program for controlling connected sonars. A demonstrational application using ROS framework was designed and implemented. Based on data received from sonars this application detects nearby obstacles and is able to maintain safe distance as well as slow down when getting too close to an obstacle. The design of the collision avoidance system is focused on high frequency of measurements and maximal space coverage.

Production of designed quadracopter using rapid prototyping
Melša, Jan ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
Design and manufacturing of a quadrocopter prototype using the Rapid Prototyping additive technology – the Fused Deposition Modeling method – is the goal of this Bachelor’s Thesis. The Thesis describes the process the prototype has to go through from the 3D computer model, through production settings down to the production itself. The individual prototype models have been created using the Creo Parametric software and they are adapted to the real components of a functional quadrocopter. The Thesis ends with a technical-economic assessment.
