Milling machine CNC control
Krejčí, Jan ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine, 3D model of that and eventual control using PLC. All axes are powered by stepper motors, with encoders, connected to control cards and industrial computer from company Beckhoff. For this control is made full switchboard, supplemented by electrical wiring diagram. Program control along with visualization is made in software TwinCAT 3. Drill-mill machine can be controlled manually or automatically by program.

Artificial aorta for activity demonstration of intraaortal baloon contrapulsation
Bičiště, Jan ; Rampl, Ivan (referee) ; Zeman, Václav (advisor)
This dissertation work describes design and construction of simulated aorta device intended to demonstrate performance of the intra-aortal balloon catheter (IAB), and to test reaction of the contra-pulsation pump during simulated cardiac output in conditions of tachycardia, bradycardia and arrhythmia. The major part of the device is transparent plastic tube. The pressure pulses (waves) are generated inside this plastic tube to simulate real cardiac output. These pressure pulses are generated by step motor with membrane. The step motor is controlled by programmable control system AMiNi-E. Individual pressure pulses simulate cardiac output in conditions of tachycardia, bradycardia and arrhythmia. Required simulated cardiac output is selected by control switches. Generated pressure pulses are read by pressure sensor and are transferred to the control system of the configuration computer. Read data can be displayed as graphs in program Microsoft Excel. The intra-aortal balloon catheter (IAB) is inserted inside the aorta and is connected with contra-pulsation pump which on pressure pulse is responding.

Wireless modular system for device control and data acquisition
Pejchal, Luboš ; Tošovský, Petr (referee) ; Kubíček, Michal (advisor)
The aim of this project is to design a cheap and simple modular wireless system. Its purpose is wireless control of remote devices and transmission of short information blocks (temperature data, status of controlled devices…). The whole system is controlled by a PC. It utilizes hybrid wireless modules for transmission of information and control of remote devices. The project shows practical usage of a digital thermometer communicating via a 1-Wire bus. A solar cell in conjunction with a DC/DC up converter is used to power low-power temperature sensor device.

Project of Engraving device for graphics creation
Hložek, Vojtěch ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The objective of this master's thesis is to design and implement a system which would be able to transfer a picture (either a bitmap or a vector image) on a foundational material. The main part of the apparatus consists of a plotter controlled by two stepping motors. The engraving itself is provided by a marker mounted to a movable part of engraving head. There was a PCB created for controlling the entire system. It contains power supplies, a microcontroller and motor and engraving head controlling circuits. The second part of the thesis shows a microcontroller program and a user interface in a PC. The image is trasfered from the PC into the microcontroller where it is processed and, based on the controlling program, engraved to the material.

Retrofit of milling machine
Krejčí, Jan ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine and control using PLC. All axes are powered by stepper motors connected to special control cards and industrial computer from company Beckhoff. For this control is made full switchboard. Programmed control is done in software TwinCAT 3. In the program is done manual and automatic control together with their visualizations.

FITkit as Step Motor Controller
Čejka, Štěpán ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
This work deals with problems related to design and implementation of a stepper motor controller based on the MSP430F2617 microcontroller and the Spartan3 field-programmable gate array available on the FITkit platform. In the work, details related to types, principles, functions and stepper-motor control methods are described in detail. Proposed control units are designed to work in two different ways of control and operating modes of motor. Features of the control units have been tested with the SMR 300-100-RI/24 step motor by the means of a custom-designed pulse generator.

Control of Positioning System for Acoustical Measerements
Pytela, Ondřej ; Číž, Radim (referee) ; Schimmel, Jiří (advisor)
This bachelor’s thesis deals with issues of remotely controlled positioning system which uses stepper motors ILS1R573PB1A0 to drive linear axes Beger Lahr PAS41BR. Stepper motors contains RS485 interface for comunication with other devices so appropriate converter was made to make a connection with personal computer via USB port. The main objective was to develop control application by using MDC_ActiveX library and development environment Visual Basic 6.

Filament mixer with variable contribution of input materials for FDM 3D printers
Hráček, Michal ; Jaššo, Kamil (referee) ; Bayer, Robert (advisor)
This bachelor thesis deals with the theory of 3D printing and 3D printers and the possibility of mixing two filaments. The work is focused especially on extruder, which is one of the main parts of 3D printer, but also on mounting and cooling the print head. In the extruder, the filament is fed and subsequently melted. Furthermore, the work mentions the problems of stepper motors, describes the used components for the practical part of the work and implementation of the entire device from PCB design, writing FW, to design mechanical parts.

Automatization of 3D stacking process
Kamenec, Jan ; Řezníček, Michal (referee) ; Buršík, Martin (advisor)
The task of my thesis was to automate the process of 3D stacking. The work includes design of complex control board, that will serve as a control unit and provide a comprehensive function of mechanical displacement in combination with digital image acquisition. In addition, the electronics for controlling a stepper motor, PCB and the design. The result of this is a facility that provides automatic acquisition of images with different depth of field.
