Design of control unit for two-wheeled self-balancing vehicle
Bastl, Michal ; Klimeš, David (referee) ; Chalupa, Jan (advisor)
This diploma thesis is a part of a project of two students. The aim of the project is to design safer electronics for the unstable balancing vehicle HUMMER and implementation of advanced diagnostics and fault detection. In the first part of the project we analysed the original vehicle using the FMEA analyse and created a new concept of the vehicle. The second part of the project describes a new hardware. I designed and tested the power electronics, control unit and supplies. The outputs of the work are prototypes which allow testing a new concept.

Formánek, Martin ; Vejlupek, Josef (referee) ; Appel, Martin (advisor)
Táto diplomová práca sa zaoberá návrhom a realizáciou výukového modelu pre študentov mechatroniky na vysokej škole. Úvod práce sa zaoberá krátkym uvedením do problematiky používania univerzálnej sériovej zbernice a jej implementáciou pre komunikáciu s mikrokontrolérom. Druhá časť je venovaná hardwaru zariadenia, medzi čo patrí voľba vhodného motoru, návrh vhodných elektronických komponentov, návrh dosiek plošných spojov a taktiež mechanickej konštrukcie celého zariadenia. Nasleduje softwarová časť, popisujúca praktickú realizáciu komunikácie, program v mikrokontroléry, a Toolbox, ktorý umožňuje užívateľovi jednoduchú interakciu s hardwarom a to jak z Matlabu. tak zo Simulinku. Kombinácia navrhnutých hardwarových a softwarových prvkov umožňuje jednoduchú cestu k zlepšeniu vedomostí študentov v oblastiach programovania, riadenia a modelovaní sústav. Pre tieto účely je práca rozšírená o pracovný list, ktorý dopĺňa navrhnuté zariadenie o sadu experimentálnych úloh, zameraných na vybrané mechatronické problémy.

Electronic Platform of the System for Eye Retina Acquirement
Malaník, Petr ; Hájek, Josef (referee) ; Drahanský, Martin (advisor)
This work deals with a control of the platform which is used for scanning of the eye retina. The purpose of this platform is the three-axis motion, camera sharpening and a controlling of LEDs to illuminate the eye. Within this is solved the issue of stepper motor control, LED brightness control and communication with a microcontroller. Part of the thesis is the programming of STM32, i.e. 32-bit microcontroller of STMicroelectronics in C/C ++ using HAL abstraction layer and Python 3 demo application.

Developement of electronics and software on robotic vehicle Car4
Michal, Mikuláš ; Rajchl, Matej (referee) ; Dobossy, Barnabás (advisor)
Tato diplomová práce se zabývá revizí elektroniky robotického vozidla car4 se zaměřením na měření rychlosti otáčení kol, výkonovou a řídicí elektroniku. Car4 posloužilo jako základ pro již přes 20 diplomových prací od roku 2010. To znamenalo, že některé základní aspekty car4 byly zastaralé. Bylo vytvořeno schéma elektroniky vozidla, které bylo dále využito pro vývoj a výrobu nového hardwaru. Komponenty byly poté otestovány a implementovány na vozidlo. Dále byl vytvořen kinematický model 4WS vozidla za použití Ackermanovy geometrie, který byl implenetován a otestován na car4. Dále by měl sloužit jako základ řídicího algoritmu pro budoucí vývoj car4.

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.

Soft-switching Methods and Optimization of Output Stage of MOSFET Driver
Trojan, Vladimír ; Pavlík, Michal (referee) ; Prokop, Roman (advisor)
The diploma thesis deals with design and comparison of optimization methods for the circuit of output stage of the MOSFET gate driver, in order to reduce voltage swing induced on the parasitic series inductance of output terminals of the MOSFET gate driver package. The proposed optimization methods are implemented on-chip and integrated into an SOIC-16 package. Implemented test structures are then mounted on test PCB, which is designed as part of the thesis. The real parameters of the proposed optimization methods are then determined using the measurement setup. The design of the optimization methods was carried out in Cadence Virtuoso environment and the test PCB was designed using the Autodesk EAGLE program.
