Positioning system for noise measuring microphones
Pulec, Václav ; Březina, Lukáš (referee) ; Singule, Vladislav (advisor)
The thesis deal with programing of algorithm for creating measuring box composed of measuring points. Coordinates of these points will be used for planing trajectory of the robot’s effector. It describes construction of structural model in Solid Works and calculate dynamic model by matrix formalism in MATLAB. In conslusion dynamic model of positioning system is used for the choice of appropriate motors.

Positioning of the tilting head of a milling multi-purpose machining center with a horizontal spindle axis
Grepl, Martin ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
The thesis deals with the positioning of the tilting head of the multifunctional milling centre in three axis. The aim of the thesis is to design a multifunctional milling machine centre with a horizontal axis of the spindle in cooperation with Bc. Ľubomír Vazovan, Bc. Ján Rapčan a Bc. Tomáš Hynšt, who are working on the issues of the headstock, automatic tool change and palletization. The thesis also contains proposals of certain options and their subsequent evaluation by the multicriterial method PATTERN. The resulting construction is complemented by calculations of the main construction nodes.

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.

System for contactless ultrasonic measuring of edema
Zahradníčková, Ludmila ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
Determination of the extent and state of a limb edema is based on information about its current volume. There are a number of methods for volume measurements. The theoretical part of this semestral thesis discusses the etiology, classification and principles of volume measurements and basic information about ultrasound and stepper motors. The practical part consists of a design of own device for a contactless limb volume measurement with ultrasonic module. It consists of a code for a microcontroller which controles the whole system including the computational operations and a real model of the system.

Optical measurement of edema of limb
Šeptun, Roman ; Chmelík, Jiří (referee) ; Harabiš, Vratislav (advisor)
This thesis deals with methods of edema measuring. In my work, I designed hardware and software solutions for a device reconstructing surface of the limb part. Purpose of my work is evaluating discussing possibilities of this device. For making 3D reconstruction of scene from 2D images I made reconstruction program. For acquisition of images a device controlled by Arduino platform was constructed, the whole device is realized in program language Matlab. In the end of the thesis is described, how to improve the device for using in real conditions.

Independent Positioner Controlled by Microcontroller
Bordovský, Tomáš ; Povalač, Aleš (referee) ; Šebesta, Jiří (advisor)
The project is focused on an analysis and design of an autonomous positioning system with high precision for an astronomical telescope or another device. Although, there are already such devices in the market, so they are too expensive for common people. These systems are used in the astronomy, radio-amateur communication and robotics or for optimum positioning of the solar panel. In this paper, requirements on construction of system working in wide range of conditions, electronic subsystems, control algorithms, and calibration method are analyzed. There are also complete circuit diagrams and printed circuit boards, also the built-up parts of the positioner are presented.

Design and construction of the drive unit for universal tips measurement micropositioning system
Zeman, Pavel ; Havlíček, Tomáš (referee) ; Pavlík, Michal (advisor)
This work deals with design and construction of the drive unit for universal tips measurement micropositioning system. Measurement system can be used for measuring parameters of structures as thick film layers and thin film layers. The parameters of substrate will be measured by measuring tips. These tips must be fixed on target position by using stepper motors with high accuracy. For movement of substrate will be used two direct-current motors. Position of this substrate is scanned in two axes by two optical CCD chips. This work contains the proposal of software for all used microcontrollers. Activity of system is controlled by certain serial bus.
