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.

MultiCopter Design
Picek, Matěj ; Pelikán, Petr (referee) ; Zdařil, Zdeněk (advisor)
In my work, I focused on the design of an electric multicopter for common and advanced users. The main objective was to bring a simple practical solution to the dron, which will correspond to the current functional and aesthetic standards of industrial design in the aircraft industry. Whole concept of the dron is designed to be as user-friendly as possible. Thanks to its simplicity, small dimensions and dron structure, it takes a minimal transport space and is almost instantly ready for use.

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.

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.

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.

Determining of Dron Localization Using Navigation Systems
Nosál, Jan ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
The thesis describes problems of drone navigation using navigation systems with which the navigation modules that have been tested are able to work. Next the issue with flight path and the determination of the incline and direction of the flight of the drones was solved also. Drones are more and more popular devices used for military, agricultural and commercial purposes. The thesis contains information about most used navigation systems which we encounter every day especially in cars and aircrafts. There were tested two navigation modules for drone localization. Modules capable of handling five navigation systems GPS, Glonass, Galileo, Beidou, QZSS and they can communicate with the Arduino board and IMU controller for drone positioning.

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.

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.

Mathematical Model of Quadcopter
Gajdošík, Martin ; Veigend, Petr (referee) ; Rozman, Jaroslav (advisor)
The aim of the bachelor thesis is to create a mathematical model of a quadcopter and its subsequent simulation in MATLAB and Simulink environment. It will also deal with a design and implementation of an autonomous control system with which we will perform flight tests in two flight configurations. These configurations will be with one or two engines in front of vehicle. We will also look at the computational complexity of this model and the possibilities of further expansion.
