Mechatronic Proposal of Electromagnetic Vibration Power Generator
Jurosz, Pavel ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with modifications to the construction of vibration-to-electricity energy converter, which is one of possible solutions to problem of sustainable and stable energy source for wireless sensor supply. Upon the exploration of the present state of this problem, new construction of generator is proposed. The aim of this proposal is to enhance the existing generator properties with respect to retention of its dimensions and its weight. Results obtained by simulations of model with proposed parameters are presented and analysed.

Modelling of linear power drive with DC motor for control purposes
Vrbka, Michal ; Březina, Lukáš (referee) ; Houška, Pavel (advisor)
In my diploma thesis, I developed the model of a linear actuator for the control purposes. The first part summarizes the literature research of currently available linear actuator systems. The work further describes some of the capabilities of the simulation environment Matlab which was used for the creation of the computer model of linear actuators. In the last part, this theoretical model is compared with already available physical model of the system.

Design and control of manipulator for laboratory measurement of temperature field
Čepička, Martin ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
Diploma thesis is focused on design of construction of a simple manipulator. It will be used for laboratory measurement of temperature field. The goal is to design model of the manipulator, build up control software and verify by simulation. In thesis is described design of kinematical model, which was programmed in Matlab. Design of model was created in Autodesk Inventor Professional, which allows to conduct dynamic and compactness analysis of manipulator. The Autodesk Inventor Professional was also used for creating the productive documentation. Control of manipulator was design in program LabVIEW. This module will serve as input module to complex of measuring work.

Control units for small EC motors with universal software interface
Vetiška, Jan ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
This graduation thesis deals with the design and realisation of the universal control unit for the electrically commutated motor ( EC motor). Was to accomplish the market research of control units for EC motors and compare of parameters of control units with requirements for the universal control unit of EC motors. From the research ensued that on the market it is no unit with the open system which could enable substitute particular control loops by own loops. Based on this evidence it was approached to own construction of the universal unit. For the design it was used the access hardware in the loop a software in the loop. It was performed the design of particular sections of the unit, manufactured the power section and this power part was tested by the help of the developmental and simulation software Labview. Furthermore it was proceeded for the realisation of the integral control unit and for supplementation of the existing software of the control unit about appropriate drivers and it was undertaken the modification of the control algorithm for the need of EC motor. On the end of this project we tested achieved parameters of the control unit.

Utilisations of the “Open Dynamics Engine” for modelling of mobile robots
Kovář, Jiří ; Ondroušek, Vít (referee) ; Houška, Pavel (advisor)
This diploma thesis deals with the problems of virtual physical modelling of mobile robots for the needs of their real-time control. To create a virtual physical world, an open-source project OPEN DYNAMICS ENGINE (ODE) was used, the results were displayed facilitating DirectX graphical interface. Simulated systems in ODE were written in C# on Microsoft.NET platform. The properites and qualities in ODE were verified by simulation in several types of simple systems and on a simplified robot model "Kracmera I.". Subsequently, the usability of ODE for its control was being verified.

Control units for small DC motors with universal software interface
Hlouš, Jaroslav ; Březina, Lukáš (referee) ; Houška, Pavel (advisor)
The purpose of this thesis is to design and implementation of the control unit for DC motors. Design is based on the concept of universal communication interface, which has been designed for simplification of communication between individual control systems. Control unit has been realized for DC motors within supply voltage range from 6 to 48 V, and maximal continuous current 2,5 A. For realization, we have used microcontroller LPC2103, and full bridge driver TLE 6209. In the thesis, we have described particular developmental steps of the control unit.

Using the EtherCAT bus couplers in the development environment NI LabVIEW
Svoboda, Filip ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This thesis focuses on EtherCAT fieldbus and its application by using NI LabVIEW. There are described the theoretical part of network elements designed for automation use in first part. Next part includes description of the EtherCAT and its advantages. There is described how NI LabVIEW accesses to this fieldbus in the next part. The real application developing process on the specific manipulator is treated then. It is controlled by the bus coupler. The results of the experiment are discussed in the last chapter.

Analysis of the Delta robot workspace
Kočan, Michal ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
The aim of this work is to analyze the workspace Delta robot, depending on the number and length of his arms. Introduction is focused on a general description of the problems in the form of theoretical part. In another part are solving problems about kinematic problems. Another section is devoted to linking NI LabVIEW SolidWorks. Using connection NI LabVIEW with the active module SoftMotion and SolidWorks interface was simulated movements Delta robot in space.
