Algorithms for browsing 2D maze
Chvíla, Lukáš ; Jelínek, Aleš (referee) ; Žalud, Luděk (advisor)
This thesis describes an automatic path finding method in a 2D maze defined by bitmap evidence grids. The problem was solved in the programming language C# with the help of the straight line decomposition algorithm used for creating a network of potential routes. The algorithm assumes approximation of obstacles by vector polygons. The resulting path was found by the means of algorithm A*. The result is a path described by line segments. After some modifications, the path could be used for robot navigation.

Measurement of laser source with a cylindrical lens
Jelínek, Aleš ; Šedivá, Soňa (referee) ; Bejček, Ludvík (advisor)
The purpose of this work is to design and create device for measuring the light intensity of laser source with cylindrical optics. It will be used to check laser source attributes during it's construction – primarily steady illumination along the whole line. The main goals were the minimization of construction complexity, reduction of cots and of course achieving all requirements. The product is fully functional machine, which works in company today.

Adaptive control of small brewery
Kalivoda, Jakub ; Jelínek, Aleš (referee) ; Kopečný, Lukáš (advisor)
This final thesis deals with adaptive control of small brewery. Contains a short description of brewing technology and adaptive control. Includes design of small brawery and control system based on STM32F407 Cortex-M4 microcontroller. For online identification is used Recursive Least Squares Method. The controller function perform a modified PSD controller with filtered derivative component, reducing the first overshot and dynamic antiwindup. The proposed adaptive controller is implemented into microcontroller. Created device i used for semi-automatic beer production.

Unit for wireless transmission of electrical energy
Jelínek, Aleš ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
The aim of this work is to prove the practical applicability of the concept of contactless energy transfer using induction coils. The first part deals with the mathematical model and theoretical proof of the concept being able to work in practice and describes the process of detecting resonance of receiver circuit on transmitter side. Next chapter describes hardware solution of the experimental prototype. The last part contains measurement results of a coupling coefficient of coils and discusses performance and notable features of the prototype.
