Outdoor Mobile Robot Self-localisation
Sárközy, Gabriel ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The aim of this work was to create a self-localization unit. The basis of the unit is an electronic platform Netduino Plus, which is connected with a measurement unit MTi-G and a camera based sensor, which is able to detect the position of points on the schools testing polygon. Configuration of the measurement unit MTi-G was done by a modified previously developed program. The program of the platform uses lover level communication with the sensor without using predefined classes from the manufacturer. This should improve the speed of processing the data from the sensor. To check the accuracy of the position provided by the self-localization unit another program was created. This program receives messages form a more accurate localization system that is mounted to the robot. The localization system is based on Trimble DB982 receiving modules.

Cellular Automata Design Optimization
Jílek, Tomáš ; Drábek, Vladimír (referee) ; Bidlo, Michal (advisor)
Focus of this master's thesis is on evolutionary design of cellular automata and it's optimalization. There are described Evolutionary algorithms and Cellular automata in first part. Thereafter, one of the new ways of transition function representation and its possible evolutionary design is presented. Name of this method is Conditionally Matching Rules. This is followed by description of realized experiments with detailed results. Finally, success with optimalization for some tasks is presented in last chapter along with discussion.

Measurement of GNSS receiver parameters
Beneš, Jiří ; Lázna, Tomáš (referee) ; Jílek, Tomáš (advisor)
Goal of this thesis is to propose and realize a viable method to determine static a dynamic parameters of GNSS receivers. Thesis begins with research of GNSS, foremostly determining position and associated uncertainties of measurement. Following chapter contains research of GNSS receivers, data flow and methods of evaluating parameters of such measurements. Summary of obtained information is then used to schedule measurements, assemble experiment and create evaluating metrics. Main selected evaluating metric is weighted histogram of deviations with extended information. Aplication of proposed metrics onto measurements of GNSS receivers augments available information of GNSS receiver accuracy for whole range of values. This metrics also supplies additional statistical information about course of measurement.

Flight Trajectory Planning for Unmanned Aerial Vehicles
Horeličan, Tomáš ; Jílek, Tomáš (referee) ; Gábrlík, Petr (advisor)
This thesis deals with the problem of planning a complete flight trajectory (ie. horizontal and vertical components) for unmanned aerial vehicles (UAV) with a main focus on maintaining a constant height and distance from the terrain. It includes the design of the trajectory planner itself, which is created in the Matlab environment. The design is mainly focused on small rotary aerial vehicles and drones. Main concepts of geolocation are discussed in the first chapters, which includes means of realization, basic terminology and theory that is needed in order to sufficiently track an object and its height on Earth. Principles of aerial survey, its use cases and means used in this thesis are also described. Following chapters present a complete hierarchical overview of the functionality of the designed planner and provide demonstrations with simulations. The practical part discusses results obtained from real flights of the vehicle.

Tools for visualisation of data from 3D laser scanners
Střižík, Jakub ; Jílek, Tomáš (referee) ; Burian, František (advisor)
Master thesis deals with the creation of the data visualization measured by 3D laser scanner using the Point Cloud method. Measured data were parameterized after loading for use in programming environment of Microsoft Visual Studio 2010 and in platform XNA. Individual data points forms the center of defined cubes which are displayed and create a scene where is possible to move through a user input in the form of a keyboard or mouse. Created algorithms were analyzed to determine the total running speed of the program, the individual as well as critical sections. The algorithms were optimized to a higher running speed of the program on the basis of analyzed data. Optimization was focused on the selection of retrieved data and on the method of their saving within the program environment. The next optimization process was based on the using of the other method for displaying of measured data points. Individual data points were displayed in form of square 2D texture replacing the cube. This square is rotating according to move of observer. Designed algorithm optimization leads to faster running of the program.

Mobile robot control and guidance using computer vision
Granát, Michal ; Jílek, Tomáš (referee) ; Mišík, Štefan (advisor)
Teória riadenia je aplikovaná takmer všade okolo nás, počnúc reguláciou teploty v našich domoch cez modelovanie správania sa trhu až po riadenie vesmírnych lodí. Dôvod, prečo je tomu tak je, je jej výkonnosť a krása, obe skryté v použitých matematických aparátoch. Kolesové mobilné roboty sú taktiež veľmi rozšírené, hlavne v priemysle, kvôli ich obrovskej nosnosti, ktorá je nevyhnutná. Veľmi presné detekovanie trasy je dôležité kvôli dôslednému riadeniu robota po jeho ceste. Jedna z najjednoduchších možností ako vynačiť trasu je použitie čiary, ktorá má iné optické vlastnosti ako jej podklad. Na detekovanie takto určenej trasy existuje niekoľko metód, ale najvýkonnejšie a najefektívnejšie je použitie kamery s následným digitánym spacovaním obrazu, ktoré je síce náročné na výpočtovú silu, ale je ním možne získať obrovské množstvo dát. Hoci táto metóda môže vyzerať zastaralo (vodiaca čiara) stále sa využíva v niektorých projektoch práve kvôli jej jednoduchosti a nízkej cene. Skutočné použitie kamery pre navigáciu všeobecne (nie pomocou čiary) je dokonca zatiaľ oblasť, ktorá je stále vo vývoji. Cieľom tejto práce je zostaviť malý mobilný robot, vytvoriť matematický model, navrhnúť niekoľko regulátorov a riadiť robot po vyznačenej čiare za použitia camery a počítačového videnia.

Rak, Jan ; Jílek, Tomáš (referee) ; Florián, Tomáš (advisor)
The goal of this project is to design and construct a LED cube for visualization and imaging attract attention. With respect to the assignment was determined resolution 8x8x8. For the overall management and communication with the PC was chosen development board STM32F4 Discovery, which, thanks to it parameters, is sufficient for this application. Cube consisting of diodes and power wires will sit on the governing board, which will include all parts of management and communication, including the controller power supply. The board will be covered by colored fabric for a better look.
