Design of a complex HIL simulator of car boot door
Obrtáč, Tomáš ; Krejčí, Petr (referee) ; Spáčil, Tomáš (advisor)
This thesis covers the development of complex HIL simulator for the fifth car door. The beginning of the thesis is dedicated to theoretical research in the area of In-the-Loop testing. Practical part describes development of HIL simulator complemented by power electronics part. A simulation environment Matlab/Simulink was used for control design and analysis. Before the beginning of the work was measured signal part of control unit and specific signal sequences were identified. The control was applied on sbRIO device from National Instruments company with the implementation of a model on FPGA. Specific requirements for sensing speed and generation of communication signals lead to creation of unique hardware for application needs. The result of the thesis is complex HIL simulator with intuitive GUI and possibility of simulations a wide range of DC motors.

Standuino
Merta, Ondřej ; Boleslavsky, Andrej (referee) ; Šedivá, Barbora (advisor)
Standuino is the inovative force in hand-made electronic music and open source hardware as well as theoretically and historically driven movement that results in artworks, bands, workshops, happenings and writings. Standuino started as a clone board of popular Arduino but adapted to even more DIY approach of eastern region (=bastl). With this powerful tool it became part of many art installations and enabled our research team to build prototypes of many different devices most importantly musical instruments. The whole concept of Standuino is inspired and covered by the story of a pioneer of media art – Standa Filip.

Design of Robot end effector with automatic tool exchange
Jirges, Radek ; Chalupa, Jan (referee) ; Krejčí, Petr (advisor)
The goal of this thesis was to design an end effector for a small robot for testing of devices with a touchscreen. The effector has to communicate with the robot via serial interface and provide feedback about used downforce. Another requirement was possibility of automatic tool change. Measuring of downforce, signal processing, and communication with robot ensures custom electronics based on STM32 microprocessor and piezoresistive sensor. The mechanism of tool change was inspired by the system used with industrial robots but customized for this application. The result of this thesis is a functional prototype of a stylus for devices with a touchscreen which provides feedback about the downforce on display and possibility of automatic tool change. The main benefit of this solution is the possibility of changing the tool for the one with one or more styluses for testing gesture-based interface what is indispensable in these days.

Support software for projection of burglar alarm systems
Fikejs, Jan ; Pust, Radim (referee) ; Burda, Karel (advisor)
This graduation thesis deals with a software design of burglar alarm. The software has been developed in compliance with the applicable standards and regulations governing burglar alarm designs and on the basis of practical experience with designing and implementing electronic security systems. The software is written in C# and uses .NET platform. On the ground of that, this software can be run on any computer with the Windows operation system. Any ground plan picture file can be used as the underlying project map on which all the object security system can be built. It makes it possible to produce both wire and wireless electronic security systems. The software includes an editable database of components and conductors used in the electronic security alarms. The database components can be created, edited and deleted through the software. The database has been saved in format XML. The software also includes a folder of picture files containing photographs of the components and schematic symbols used in the software. You use a mouse to drag and drop individual components into the ground plan picture, where they are well arranged in a tree structure. The components can be interconnected by a conductor, which enables creation of a precise design of the electronic security system of the object. The software output includes drawings, bills of material and pricing. As for the space components, you can graphically display their range and thus visually confirm the design. The software includes automatic design verification. There, you can verify whether the right components have been used and whether the designed conductor lengths are acceptable, whether they correspond with the system load, and whether the voltage drops on the conductors do not exceed the permitted limit. The software has been developed for all electronic security system designers and for engineers attending to these problems.

Redesign of the construction and control algorithm for an unstable robot with a spherical base
Novák, Vlastimil ; Najman, Jan (referee) ; Spáčil, Tomáš (advisor)
This bachelor thesis deals with the redesign of an unstable robot with spherical base, also known as Ballbot. The aim of the work is to analyze the existing structural elements of the robot, available sensors, control and power electronics and identify functional deficiencies. Subsequently, design a solution and implement it in order to eliminate all found deficiencies. Part of the work is testing a revised version of the robot, which, among other things, consists of checking the functionality of individual sensors and checking the comunication between sensors and microcontroller. Emphasis is placed on determining the real accuracy of newly used sensors depending on the settings used and ambient conditions.

Design of the hobby CNC milling machine
Hrala, Adam ; Tůma, Jiří (referee) ; Štěpánek, Vojtěch (advisor)
The focus of the bachelor's thesis concerns the design of a CNC model milling machine. It includes a representation of the kinematics of individual types, operating systems for these machines, hazard analysis and market research. In the second part there is a design of the overall device from the point of view of the drive and guidance of individual axes, the electronics used and a design of the machine structure supplemented by a drawing of the assembled device.

Prostředky a způsoby výuky elektrotechniky v rámci biomedicínského inženýrství
Harabiš, Vratislav
Obory biomedicínského inženýrství umí být zaměřeny různými směry. Někde se klade větší důraz na medicínskou techniku, návrhy zařízení, obvodů a jejich simulace, zatímco jinde je tento obor zaměřen spíše na bioinformatiku a zpracování signálů a obrazů. Nicméně i v případě bioinformatického zaměření je potřeba studentům předat základy elektrotechniky, protože představuje základní principy, které jsou obsažený ve všech moderních přístrojích a analyzátorech.
