Precision and dynamics of linear piezo motors
Ilichman, Ondřej ; Vaške, František (referee) ; Houška, Pavel (advisor)
The work deals with the design, control, precision and dynamics of linear piezoelectric motors from PiezoMotor Uppsala AB. The aim of this thesis is to evaluate the applicability of the loaned engine in a mass spectrometer. In introduction‘s section of this work is discussing the design principles of functionality, materials used, procedure and types of piezoelectric motors. It focuses the choice of hardware and design of mechanical assemblies, which could replace the current mechanism with electromagnetic motors. Then we designed and fabricated a test report with hired piezoelectric motor. In NI LabView development environment is created test application for control and measurement. The final section is devoted to a summary of the positive and negative features of the hired piezoelectric motor and evaluation of accuracy and dynamics.

Controller design with using CARLA method
Jasanský, Michal ; Houška, Pavel (referee) ; Březina, Tomáš (advisor)
This bachelor thesis is focused on the application repeatedly reinforcement learning method named „Continuous Action Reinforcement Learning Automata“ (CARLA). There is recapitulated a basic describe of the artificial intelligence method, however it deals mainly with the CARLA method. In the thesis are described the advantages, disadvantages and the type of mathematical basis for simplified version of the CARLA method. The main part of the thesis is concerned with the method testing and debugging. The influence of the setting the parameters is also demonstrated in the thesis. The method is successfully applied on two systems: DC motor and physical pendulum.

Mechatronics design of furniture dowels producing machine
Šubrt, Kamil ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
This work deals with the suggestion of self-operating machine for the manufacture of furniture pins from the cylindrical pin blanks. The paper analyzed the possibility of production automation of furniture pins, which has been based on long experience with their production. Subsequently, there was suggested a design of machine using V-cycle methodology. In this proposition was gradually developed the machine construction and its management. Construction of this machine presented by 3D CAD model is connected to the development environment NI LabVIEW. Operating of the machine was designed and verified through co-simulation. The machine proposition was achieved trough successive iterations of development which meets the requirements. In the conclusion of this project was done analysis of choice suitable management system for the real machine.

Leak testing of pneumatic components
Staňo, Martin ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This diploma thesis is focused on the issue of pneumatic components testing and air leakage measurement. The current state of the given issue is summarized based on the analysis of leak testing methods in accordance with valid legislation. The aim of this thesis is to design methods for pneumatic components testing according to specification. As part of method verification, a pneumatic circuit with a pressure control system has been assembled, on which functionality tests of provided components and leak tests by the pressure-drop method have been performed. The results of these tests have been subsequently evaluated as consistent with the specification.

Measurement and visualization of parameters in hydraulic circuits
Říman, Matěj ; Kroupa, Jiří (referee) ; Houška, Pavel (advisor)
This bachelor's thesis deals with measurement and vizulation of the hydraulic circuits. First part of this work introduces a selected hyraulic task. Following chapters describe the possibilities of measuring hydraulic parameters, along with the principles of pressure sensors, flow and temperature. The following section describes measurement application in NI LabVIEW which is used to wiew and export relevant data related to measuring. The last chapter is an evaluation of the application, along with a demonstration and description of output measurement

Microcontrollers programming possibilities
Šubrt, Stanislav ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This work is focused on inner structure and programming possibilities of microcontrollers. The work goal is to describe inner structure of microcontrollers from the programmer’s point of view, find out advantages and disadvantages of their programming in Assembly language, C language and higher-level languages. Code portability between different microcontrollers’ families and architectures is discussed further.

Design of nameplates editor
Svoboda, Filip ; Kroupa, Jiří (referee) ; Houška, Pavel (advisor)
The diploma thesis deals with the problematics of type labels, used for marking of products in series production. The research part of the thesis deals with the issues of the used label media and label printing. The issue of content and design of labels is analyzed. The result of thesis is a graphic editor for designing labels and their translation into ZPL II. This language is mainly used by Zebra Technologies printers, which are very common used in industry.
