This doctoral thesis originated as a requirement of micropump for artificial heart with using a suitable type of electric drive. It is an interdisciplinary cooperation of FSI Brno, Department of Fluid Engineering of Viktor Kaplan, FEKT Brno, Department of Power Electronics and finally the doctors from Cardiology Medical Center in St. Ann’s Hospital. FSI Brno made mechanical solutions of micropump, FEKT Brno solved electric drive and Cardiologic Medical Center gave the knowledge of human anatomy. Work deals with design, creation and testing of various types micropumps for medicamentous using. In this thesis was suggested various solutions of electric drive for micropump, its structure and function. Work is primarily experimental in nature and is heavily supported by a creative approach in creating a variety of proposed solutions. Several proposals of micropump have been made with different types of electric drives (DC motors, hybrid stepper motor, piezomotors). Finally, from the technical and economical point of view was chosen the most suitable type of electric drive and it was created a functional prototype of the double-action pump and its properties were tested.

Abstract:
Cílem této práce je vývoj dvoukanálového kontroléru krokových motorů. V rámci práce je popsán jak vývoj elektroniky, tak vývoj příslušného software. Elektronika kontrolŕu je založena na mikrokontroléru STM32F405 a driverů krokových motorů vyráběných firmou Trinamic. Pro komunikaci s nadřazenými systémy je implementován protokol CANOpen a sběrnice I\textsuperscript{2}C a USB. Elektronika byla navržena v software KiCAD and využívá čtyřvrstvého plošného spoje a moderních výrobních technologií. Co se týká software, byl vyvinut jak firmware pro mikrokontrolér, tak software pro ovládání kontroléru. Obě části software využívají programovacího jazyka Rust, který se zaměřuje na bezpečnost práce s pamětí, rychlost a zero-cost abstrakce. Sekundárním cílem této práce je ukázat, jak lze tento programovací jazyk s výhodou použít pro programování nízkoúrovňového embedded software. Firmware kontroléru implementuje nezávislé řízení pohybu obou os kontroléru a to jak v rychlostním, tak v pozičním režimu a zároveň implementuje bezpečnostní funkce pro případy selhání komunikace. Výsledný kontrolér by měl být použit v rámcí výzkumné skupiny Robotiky a Umělé Inteligence a studenty na Ústavu Automatizace FEKT VUT.

Abstract:
This diploma thesis deals with the structural and optomechanical design of automatization of focusing laser beam for a remote laser spectroscopy device. The chosen solution uses an active rangefinder and a rotary unit to control the change of the focus plane of the device's optic system. The dependence of the focus plane’s change on the shift of lens in the focus plane was practically measured. For proper control of the rotary unit, this dependency is needed. Structural parts were made based on the created drawing documentation. The structural parts were mounted in the existing assembly of the device together with the purchased components. The proposed solution enables a change of the optical system, for example, in order to obtain a more appropriate range of focal planes.

Abstract:
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.

There are developed theoretical part of the physiology of vision, then writing available methods that are now widespread for obtaining stereoscopic scene. The work also describes shooting dynamic scene using a pair of identical cameras. It focuses mainly on OFF-AXES method and deals with the topic of the settings stereoscopic base. There is also realized a practical part, which works with the capture dynamic scenes using video cameras with a automatic control of cameras distance. Automatic control is performed using the parallel port and a stepper motor. For this purpose it is designed to work in hardware support and a program for mutual communication. Filmed a short movie was screened to a group and those observers evaluated the parameters that were specified in the created poll.

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.

Abstract:
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.
