Liquid Crystal-Based Computational Platform
Klázar, Jakub ; Šimek, Václav (referee) ; Bidlo, Michal (advisor)
This work explores the possibilities of computations in a liquid crystal, specifically focusing on the logical operations. The text focuses on the design, build and use of a platform for performing experiments on computation in a liquid crystal. The platform is a device to which an LCD display can be connected as a experimental liquid crystal and experiments can be controlled from a computer through this platform. Experiments use, among other things, evolutionary algorithms. Further, the paper deals with the execution of experiments, discussion and processing of results and then creating conclusions of it.

Embedded System for Water Level Monitoring
Hanák, Jiří ; Kašpárek, Tomáš (referee) ; Šimek, Václav (advisor)
This work is dealing with the design and implementation of an embedded water level monitoring system. The purpose of the system is to control the filling of a tank based on the water level. First of all, the attention is given to the survey of existing measurement techniques and selection of the appropriate sensing elements for a given scenario. In fact, the embedded system is using TFmini and JSN-SR04T-2.0 contactless sensors. The system is controlled by STM32F0 microcontroller from STMicroelectronics programmed in C using HAL abstraction layer. The measured results are sent via Wi-Fi SoC ESP8266EX to the Python server that is used for processing and demonstratiton purposes.

Segway driver parameter estimation and its use for optimizing the control algorithm
Dobossy, Barnabás ; Zouhar, František (referee) ; Brablc, Martin (advisor)
Táto práca sa zaoberá vývojom, testovaním a implementáciou adaptívneho riadiaceho systému pre dvojkolesové samobalancujúce vozidlo. Adaptácia parametrov vozidla sa uskutoční na základe parametrov vodiča. Parametre sústavy sa nemerajú priamo, ale sú odhadované na základe priebehu stavových premenných a odozvy sústavy. Medzi odhadované parametre patrí hmotnosť a poloha ťažiska vodiča. Cieľom práce je zabezpečiť adaptáciu jazdných vlastností vozidla k rôznym vodičom s rôznou hmotnosťou, kvôli zlepšeniu stability vozidla. Táto práca je pokračovaním predchádzajúcich projektov z roku 2011 a 2015.

Class D audio amplifier for laboratory measurements
Svorad, Adam ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
Bachelor’s thesis delves into a field of Class-D audio amplifiers. Keystone part of the work summarizes theoretical knowledge focused on measuring techniques of lowfrequency amplifiers and audio amplifier design. A deeper insight into building blocks of a general Class-D amplifier is also presented. Gained erudition is applied in the second part, which is devoted to a construction of the device. Exceptional attention is drawn to the design of robust external driver and sophisticated output analog filter. Blueprints required for a PBC layout are provided as well as outputs of performance measurements taken of a fabricated prototype.

Temperature control and monitoring system
Mitter, Martin ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This work is dealing with the design for maintaining and monitoring optimal temperature for home-based data center. The purpose of this work is to prolong the life of hard drives in data center for as long as possible. First of all, the attention is given to establishing what the optimal temperature for maintaining long-live of hard drives is and how to correctly measure it. Based on the knowledge obtained from theory and from the prototype testing the final design of embedded system for maintaining this function is created.

Embedded Device for Robotic Arm Control
Kyzlink, Jiří ; Goldmann, Tomáš (referee) ; Orság, Filip (advisor)
This diploma thesis deals with a design and implementation of an embedded device (module), used to control a robotic manipulator. The module instructs servomotors of the manipulator to move according to the commands received via USB interface. The module consists of two double-sided printed circuit boards. The first one allows connection to the CAN bus, redundant and thus reliable power supply for servomotors as well as the whole module. The second board, compute oriented one, embeds powerful microcontroller used to communicate with the servomotors and to solve the kinematics tasks. As a part of the thesis a graphical user interface as well as a web-oriented interface were developed. Both interfaces allow full control of the manipulator. All the communicating buses, tools and methods used during the design and implementation phases of the work are described in the thesis. Finally, measurements proved improvement of the motion smoothness and response times in several orders of magnitude in comparison to the previous system.

Control system of mouth-organ
Trukhina, Irina ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
The master’s thesis describes development of control system for automatic mouth-organ. The process of development is divided into three parts: a concept of control system, design of hardware parts and development of software parts. Controlled device, system requirements and general design of the hardware and software components are described in the concept of control system. The detailed hardware design includes next processes: electronic component selection, printed circuit board design, assembly and debugging. The result of this chapter is electronic system, which function correctly. The aim of the last chapter is to specify and explain development of software parts of control system. Installation of required software and important aspects of control software and user interface development are described in this chapter. The goal of the thesis is to create a control system, which will function correctly and reliably.

Controller for quadrocopter
Tilgner, Martin ; Kříž, Vlastimil (referee) ; Burian, František (advisor)
This thesis deals with design and creation of control board for the type of drone quadrotor. The aim of this work is to design create a control unit capable of drone stabilization and communication with superior system. It is assumed that there will be used open source firmware for quadcopter controlling. The work is divided into five parts. The first one deals with the quadrocopter flight principle and creation simple physical model of the quadrocopter. The second part deals with electrical motors for small flying machines and the suitable operating electronics. The third part deals with sensors necessary for flight stabilization and their selection. The fourth part deals with design and creation of PCB control board for the quadrocopter and the fifth part deals with the operating software.

Shooting sport simulation device
Poloch, Martin ; Musil, Vladislav (referee) ; Šteffan, Pavel (advisor)
The goal of this diploma thesis is to design a shooting sport simulation device. Output of this project should be a market competitive product therefore the design should be focused on low price. Other important aspects are safety, reliability and mutlifunctionality of the whole system. Shooting simulation is based on special technology of sensing laser beams with LED developed in author´s bachelor thesis. The system is controlled by a group of microcontrollers. Their program running and communication is a key part of this thesis.
