Design of special purpose tool for sag measurement
Mejzlík, Jiří ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The aim of the thesis is to design a special purpose tool for sag measurement. Three possible solutions are proposed, for each the production cycle time is calculated and its approximate costs are estimated. The best solution in terms of a trade-off between both key quantities is suggested. Next part of the work deals with the selection of suitable drives for the manipulator as well as of the other components for the whole electrical device. Finally, a possible automated control of the complete machinery, including the electrical wiring diagram, is presented.

Control modernization of two-axis manipulator
Mejzlík, Jiří ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis addresses the modernization of two-axis manipulator that is a part of the galvanizing line. The introductory section describes and evaluates the current situation and specifies the requirements for the device modernization. The selection of the proposed control is based on the analysis of possible solutions which are described in this work. The next part deals with the selection of suitable components and describes the process of implementation.

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.

Design of explorative underwater robot
Válek, Zdeněk ; Věchet, Stanislav (referee) ; Houška, Pavel (advisor)
This bachelor's thesis is dealing with design of an explorative robot. The robot is designed especially for the exploration of the underwater part of Hranická propast, the deepest abyss in the central Europe. Its exploration is complicated by several limitations that the robot have to challenge. These limitations take effect mainly in the design of sensor system. The design of construction is affected mostly by the maximal operating deep request.

Design of instrument for the analysis of crack initiation and propagation
Šubrt, Stanislav ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
The main goal of this thesis is to get an insight into a field of non-destructive testing using potential drop techniques that have nowadays become the standard not only in the fatigue and loading tests but also in the industry. These methods can serve to non-destructively and continuously measure material specimens, thickness, corrosion losses, deformations, spectroscopy and detection and analysis of crack geometry. They can help to identify materials and measure material changes over time. The second part of this thesis deals with designing the aperture for detection of cracks in steam and product piping using potential drop technique modified by Ing. Ladislav Korec, CSc. Last part deals with extensive testing, experimenting and evaluation of the aperture.

Design equipment for measurement the surface wettability
Šubrt, Kamil ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
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.

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.

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.

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.
