System of Intelligent Flower Pots for Indoor Plants Growing
Kinc, Michael ; Mrázek, Vojtěch (referee) ; Šimek, Václav (advisor)
Nowadays, when technologies from the world of the Internet of Things are gaining popularity, new possibilities are opening up for the automation of common daily tasks with the help of smart devices. Such a device is also an intelligent flower pot, thanks to which the premature death of the plant can be prevented, as it may be able to warn the grower in time of deteriorating values measured from the soil or the surroundings of the monitored plant. The goal of this work is to create a system of intelligent flower pots for indoor plants growing, which can be controlled through an information system and a web application, in which the user has an overview of his flower pots, the state of the plant and the measured values.

Extension of the magnetic manipulator teaching model using a microcontroller for independent operation
Štupák, Jakub ; Králík, Jan (referee) ; Appel, Martin (advisor)
This thesis deals with the design, control and user interface for a magnetic manipulator. Created magnetic manipulator uses three electromagnets, which are used to control the position of a steel ball. The objective of this work was to enhance and extend the functionality of this system, including adding the ability for autonomous operation. Regulation can be executed through either an externally connected HUMUSOFT card or an integrated microcontroller. This enables the use of this system without external hardware and simplifies manipulation. Communication between the system and user is enabled with the use of the ESP32 Bluetooth functionality and an Android app.

Test benches for microcontroller kits
Žaludek, Ivo ; Burian, František (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the design of a test bench for functional testing of educational kits. These kits are in the form of standalone printed circuit boards, for instance, a module with a microcontroller and its peripherals, such as a display, keyboard, or external memory. A comparison of commercially available testers is conducted, and the requirements for testing of each printed circuit board are identified. Based on these requirements, the design of both the hardware and the software of the test bench was developed. The final stage of the project is the evaluation of the functionality of the test bench.

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.

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.

Manipulator Control for Acquisition of the Eye Retina
Malaník, Petr ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
To use the image of the retina for biometric or medical purposes, it is necessary that the image is of the highest quality and ideally covers the largest possible area. It is therefore necessary to move the sensing device to the most suitable position while ensuring its stability. A laboratory handling platform is used for this purpose. The platform is moved by stepper motors. A control board equipped with a microcontroller has been developed for their control, which allows very fine movements. The theoretical accuracy of the manipulator is up to 20 nm. Since it is necessary for sensing, to have proper retina illumination, the control system also includes adjustable illumination elements in the infrared and visible spectrum. The resulting system allows scanning of the retina of the eye from multiple angles and thereby effectively increase the area on which it is possible to further look for diseases or biometric features.

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.
