Design and realization of the pull strength measuring device for SMD
Valíček, Jan ; Klíma, Martin (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design and implementation of a device for measuring pull strength by surface mounted devices (SMD). It analyzes the theory of pull strength testing of solder joints with emphasis on standard IEC 62137-1-3 and describes the selection of components utilized to create mechanical construction and electrical parts. These electronic parts made or innovated in this work were control system based on microcontroler Atmega164P, power circuit for stepper motor and communication of measure equipment TEST 321 with PC. The whole design is complemented by simulation of mechanical stress to the critical components using ANSYS. The conclusion summarizes the most important parameters of this equipment.

Stepper motor driver equipped with industrial communication
Nepivoda, Tomáš ; Baštán, Ondřej (referee) ; Arm, Jakub (advisor)
The main goal of this bachelor thesis is to design and realize driver for stepper motor, which could be controlled by supervising system using modern industrial communication network. The basis od this thesis is theoretical study on the subject of stepper motor drivers and industrial communication in the field of embedded systems. This theoretical study is then used for selecting the proper communication network and creating concept od the stepper motor. Thesis further describes design procedure and realization of hardware components and subsequent implementation of frimware. Last part of the thesis is dedicated to the creation of simple master device, which would be used for driver testing.

Automated measurement with monochromator in LabVIEW
Jakeš, Libor ; Vágner, Martin (referee) ; Havránek, Zdeněk (advisor)
This bachelor´s thesis is dealing with plan and realization of automated measuring with monochromator. The next goal of this thesis is familiarizing us with control programs, which I have created in LabVIEW. I am going to control the monochromator by means of measuring card NI myDAQ and at the same time acquisition data from the optical photodetector.

Indoor Robot - Mechanical Construction and Power Electronics
Maťas, Marek ; Veselý, Miloš (referee) ; Žalud, Luděk (advisor)
The thesis is divided into several logical units. In the first part is described the topic of mobile robotics, construction, propulsion and control of mobile robots. Other parts are devoted to the design of robot’s mechanical structure, calculating the requirements for the proposed type of engines and drives. Finally, the control electronics for these engines is proposed, along with a program for microcomputer.

The focus control unit for the optical microscope
Flek, Petr ; Řezníček, Michal (referee) ; Adámek, Martin (advisor)
The aim of bachelor thesis was to focus on the issue of creating photos with great depth of field, which are developed on an electronically controlled optical microscope with photographic equipment. Arduino module with a series ATMega (Atmel Corporation) microcontroller, that was selected for management control device has been described in detail in the next section. Work includes the design and implementation of the control unit, which automates the process of capturing digital images from the microscope. The control unit contains a module Arduino with ATmega328 processor, which controls the stepper motor connected to focus of the JENAVERT microscope (Carl Zeiss). Device communicates with the user by buttons and LCD display.

HC08-Based Controller of a Step Motor
Hájek, Josef ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
This bachelor's work deals with issue of stepper motors and their control using single-chip microcontrollers. Target of the work is to be familiar with method of operation of stepper motors, with their abilities and restrictions in case there are used in built-in devices. The part of the work is a proposal of control unit of chosen stepper motor and interconnection with developmental kit 908LJ12-G2. Implementation part of the work contains software for eight-bit microcontroller Motorola MC68HC908LJ12 programmed in language C. The stepper motor can be controlled by this program using the available kit's interfaces.

Loose-it-all machine
Švik, Ondřej ; Hůlka, Tomáš (referee) ; Cejpek, Zdeněk (advisor)
This bachelor thesis deals with the design and construction of a prototype of a “lose-it all” machine for educational purposes. The lose-it-all machine serves to implement a simple gambling game. The machine uses proprietary jettons as currency. The practical part of this bachelor’s thesis is dedicated to the description of the functionality, design, basic features, build construction, and the software solutions of the machine. It describes the physical implementation and creation of the various necessary parts of the lose-it-all machine. The theoretical part of this thesis includes research about gambling as well as an introduction to hazard addiction and its prevention.

Design equipment for measurement the surface wettability
Šubrt, Kamil ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
This paper describes the design of equipment for measuring the wettability of surfaces. Surface wettability is determined by analyzing the profile drops, in an image taken with a digital camera. After the equipment is required to automatically find and focus the analyzed drops, taking the image, measuring wettability and save the image analysis, including measurement results to a file for subsequent offline analysis and archiving. The proposed facility is designed as a three-axis manipulator. For the driving the axes are chosen stepper motors. A key factor in achieving the highest possible speed measurement is very smooth movement of the manipulator, which is achieved by controlling of motors in microstepping mode with very high resolution. Software entire system is designed in the NI LabVIEW development environment for image processing was used module NI Vision.

Remote control of low voltage curcuit-breaker
Brtnický, Jiří ; ABB, Stanislav Korčián, (referee) ; Bajer, Arnošt (advisor)
The work deals with design and contruction of the extension module remote control, through which the starter motor is remotely controlled. On the basis of specified input parameters such as size, engine type, engine power, voltage, etc., is given control module design, which includes a control unit (microprocessor) for remote control of motor drive and assessment of motor starters. The work also includes analysis of the problems of mechanical transmission, depending on the management and selection of an engine. This work is finished with the physical realization of a prototype control program by drawing a flowchart and manufacture of printed circuit boards with subsequent recovery and testing.
