Modeling and Simulation of Mobile working machine Powertrain
Zavadinka, Peter ; Věchet, Stanislav (referee) ; Kriššak,, Peter (advisor)
Táto diplomová práca sa zaoberá vytvorením dynamického modelu mobilného pracovného stroja. Ciežom práce je vytvorenie blokového modelu pohonu štvorkolesového mobilného pracovného stroja. Model hydrostatického prevodu bol dodaný firmou Sauer-Danfoss. Model mobilného pracovného stroja bol vytvorený v programe MATLAB-Simulink. Dalšou časťou práce je výber typu riadenia hydrostatického prevodu a návrh riadiaceho algoritmu hydrostatického prevodu. Výstupom práce je blokový matematicko-fyzikálny model pohonu štvorkolesového mobilného pracovného stroja spolu s riadiacim algoritmom hydrostatického prevodu v prostredí MATLAB-Simulink.

Vision system implementation on Bioloid robot
Ropog, József ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
Tato bakalářská práce se zabývá implementací systému vidění na dvounohý humanoid robot ze stavebnice Bioloid. Systém vidění je složen z bezdrátové kamery, která je namontovaná na robotovi a z řídícího počítače. Cílem této práce bylo zkonstruovat a oživit humanoidního robota, vytvořit systém vidění a bezdrátový komunikační systém. V centru je robot, který pomocí bezdrátové komunikace současně odesílá i přijímá údaje. Tento systém nabízí skvělé schopnosti na další rozšíření.

Evaluation of image processing methods for flying object tracking using drone
Daniš, Stanislav ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
The bachelor thesis was focused on the evaluation of tracking algorithms contained in the OpenCV library against the motion blur effect. A dataset of videos was created with defined ranges of selected parameters that influenced the motion blur effect (speed, distance from the object, position of light and others). Each of the videos was processed using a tracking algorithm. From these results, findings on the effectiveness of each of the algorithms for a defined situation were formulated in the conclusion.

Biocompatible metallic materials
Mišáková, Liliana ; Věchet, Stanislav (referee) ; Němec, Karel (advisor)
This bachelor´s thesis, which was processed in the form of literary research, deals with the issue of biocompatible metallic materials. The aim of this work is to provide an overview of the materials used in general medicine and dentistry and to present the latest knowledge of their development. The first part is devoted to the characterization of biomaterials and their division. In the next section, metals and their alloys are listed together with their desired properties and typical applications. The following section focuses on the method of surface treatment of titanium, which enables it to achieve better bioactivity. The final part of this thesis offers the latest findings on the properties and the way of using low-melting-point alloys.

Design and realization of odometry sensors for mobile robot with Ackermann steering
Porteš, Petr ; Věchet, Stanislav (referee) ; Hrbáček, Jan (advisor)
Aim of this thesis is to design and construct odometric sensors for a mobile robot with Ackermann steering Bender 2 and to design a mathematical model which would evaluate the the trajectory of the robot using measured data of these sensors. The first part summarizes theoretical knowledge, while the second, the practical part, describes the design of the front axle, the design and the operating software of the front encoders and the odometric models. The last part deals with the processing and evaluation of the measured data.
