Evaluation of data captured by UAV
Martináková, Veronika ; Setnický, Viktor (referee) ; Kalvoda, Petr (advisor)
The master´s thesis deals with the application of unmanned aerial vehicle (UAV) in photogrammetry and mapping. The first part describes the UAV that was used for imaging, legislative restrictions resulting from its operations, planning and realization of the flight. The second part of this thesis is focused on processing results, especially on evaluation the accuracy of the results gained by UAV with and without a GNSS module. The data are evaluated in the 3rd accuracy rating class (ČSN 01 3410). The theoretical principles are explained as well. The main aim of the thesis is to demonstrate the effective use of the GNSS module Emlid Reach and the unmanned aerial vehicle in geodesy.

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.

Analysis of multicopter design concepts
Zeman, Petr ; Koštial, Rostislav (referee) ; Dvořák, Petr (advisor)
The main objective of this thesis is to design multicopter with very high flight endurance compared with commonly achieved performances. The beginning is devoted to description of the commonly used terms and components on multicopters with MTOW up to 20kg. This part is followed by detecting dependencies of parameters between themselves from parametric analysis commercially available platforms. Subsequently are investigated factors affecting the efficiency of the propulsion unit like motor location on the arm and the voltage of the battery. Next is done comparison in terms of efficiency of configuration with one motor per arm and two motors in coaxial arrangement. In research the coaxial configuration one part is dedicated to the determination of the efficiency at different speeds of two motors and different directions of propeller rotation relative to each other. Subsequently is determined reference characteristic for efficiency of propulsion units with different weights. Especially in connection with the next part is here shown comparison of Li-Ion and Li-Po battery. The last part is about design multicopter based on previous findings.

Stability Control of Quadrocopter
Nejedlý, Jakub ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This work deals with physical laws affecting behavior of a quadcopter as a mobile robot. It describes methods of controlling movements and stability. The result of the theoretical analysis is creation of simulation model. Moreover it depicts practical software developement of a real machine controller unit with its own conclusion, comparison between simulation and practical experiments and the workflow of the physical system construction.

Multicopter Attitude Estimation Using Dynamic Model
Baránek, R.
The paper is focused on attitude estimation of multicopters. Specifically the use of dynamic model of multicopter in the attitude estimation algorithm is investigated. The examined algorithm is compared to the standard algorithm GPS-INS, which do not need any information of the vehicle dynamics. Both algorithms are tested in simulations. The use of dynamic model provides bounded errors of attitude estimates even without GPS measurements. The drawback is the need for a good dynamic model of the multicopter and its parameters.

Multicopter - dynamical model
Musil, Filip ; Němeček, Jakub (referee) ; Kraus, David (advisor)
Bachelor's thesis Multicopter - dynamic model deals with basic principles of multicopter flight and determining the position in space. Next part of the thesis is dedicated to the search of possible methods of compilation of dynamic model and implementation in Matlab/Simulink environment. The aim of this work is compilation of simplified dynamic model of multicopter which aims approximate real behavior in space.
