2D position sensor for planar positioning platforms
Brisuda, Dominik ; Adámek, Roman (referee) ; Rajchl, Matej (advisor)
This bachelor thesis deals with processing of the overview of 2D position sensors available and suitable for mechatronic systems such as “Ball on plate system”. With these systems it is inevitable for the system regulators to receive the most precise coordinates of the body position in sufficiently fast time. Another important thing is the shape, size, weight, and material of the regularized subject moving on the sensor. This statement follows, that different types of sensors will have different reactions for the given subject. Therefore, there is an overview of types of 2D sensors in the first part of the thesis. Afterwards, their suitability for given systems was considered. In the second part of the thesis there is a project of a unit for signal processing. This unit will record the signal from the sensor and drive it onto 2 outputs, which output voltage values will represent the placement of object on the sensor. By this processing, the position will be easily worked with, for example to bring it straight to the regulator. In the last part of the thesis the system was tested. The speed of scanning unit was measured, as well as the quality of the tested sensor. With the sensor quality linearity, minimal activating force and noise of the output signal on different places with different ballast weight were measured.

System for Autonomous Navigation of Toy Car on a Race Track
Katrušák, Jaroslav ; Bidlo, Michal (referee) ; Šimek, Václav (advisor)
The goal of this project is the implementation of a system for autonomous control of a toy car model on a racetrack. First part of this project is a study of typical ways of laying out a racetrack for the movement of a model car and a follow-up study of possible ways of implementing the autonomous movement of the model on the racetrack. The next part is devoted to the hardware and software side of the implementation of the proposed system. The penultimate part presents the proposed system for obstacle detection, it's implementation and resulting properties. The last part of the project presents the final implementation of an autonomous model capable of independent driving on a set racetrack, reading signs and reaction to obstacle located on the track.

Double-gate biosensor of glucose based on functionalized graphene
Malatinová, Michaela ; Pavlásková, Lucie (referee) ; Bartošík, Miroslav (advisor)
V tejto bakalárskej práci bola skúmaná funkcionalizácia grafénu s sukcinimidyl ester pyrenbutanovou kyselinou a enzýmom glukóza oxidáza pre detekciu glukózy biosenzorom. Funkcionalizovaný grafén bol implementovaný ako kanál v poľom riadenom tranzistore pre výrobu biodetekčného zariadenia. Proces funkcionalizácie potvrdila Ramanova spektroskopia a mikroskopia atomárných síl. Charakterizácia senzoru a jeho kvalít bola sledovaná pomocou transferových kriviek a časovej odozvy senzoru. Posun Diracovho bodu a jeho poloha boli analyzované v závislosti na rôznych koncentráciach glukózy s ohľadom na efektivitu funkcionalizácie. Výber hradlovej elektródy v grafénovom poľom riadenom tranzistore bol skúmaný vzhľadom na jeho možný dopad na výsledky merania.

Using the ADAM industrial sensor system in laboratory measurement
Nos, Pavel ; Chmelař, Milan (referee) ; Rampl, Ivan (advisor)
Main task of the Master Thesis is to introduce into sensor systems used in the field. On Advantech sensor system with use of ADAM 4000 modules is shown decentralized sensor system which comunicates over RS 485 and using master computer. Within Master Thesis was compiled measuring board and were assembled three programs which demonstrate possible use of different types of modules. Main development environment is used ADAMView. Each modules has different number and types of inputs and outputs. Using of sensor system saving measurement time, increasing measurement effeciency, relieves data processing and automatize measurement.

Gateway for Smart Home
Čechmánek, Martin ; Žádník, Martin (referee) ; Novotný, Tomáš (advisor)
In area of Smart-home control, there are requirements for miniaturisation, security and advanced control logic of individual member of system at present. One of the challenges is the way of data collecting from terminal nodes and data processing, including their distribution to the others nodes of Smart-home. The goal of this thesis is to design and to produce Smart-home control node, which will be a gateway between sensoric net and database and will be developed and produced on embedded system with speci c HW boards. Functionality of this gateway should include error states, e.g. should cache sensor messages when the connection between gateway and server interrupts, or take care about time synchronising. The thesis describes theoretical side of gateway design and also practical side of programming and producing SW for the gateway in Smart-home system.

Design of intelligent wiring Foxtrot for multipurpose building
Račuch, Marek ; Tesař, Radek (referee) ; Bátora, Branislav (advisor)
The present bachelor thesis is concerned with system wiring. Possible applications, various types of bus systems and wiring topology are discussed in the paper. The thesis is structured into three main sections. Section 2 elaborates on the capabilities, structure and topology of system electro installation and the third section discusses a system electro installation Foxtrot in particular, describing individual components with an overview of basic modules for utilization in residential buildings. The overall structure of system wiring is described along with a brief description of basic system components of Tecomat Foxtrot from Teco a.s. company suitable for home installation. Section 4 focuses on description of the designed object and for the proposal of the whole project of system wiring using the elements of the Foxtrot system for multipurpose building.
