Micro-hydraulics system design
Pitaš, Martin ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
One of the main aims of presented bachelor's thesis is an implementation of hydraulic circuit by micro-hydraulics system. Bachelor's thesis has three main part. First part deals with hydraulic distribution and selection of acceptable devices of hydraulic circuit, especially their advantageousness in term of finance. Second part is devoted to the construction of fixation for the position sensor on linear hydromotor, holder for hydraulic valve and hydrogenerator. Third part describes to hydraulic circuit, right hydraulic oil for whole hydraulic circuit. The verifying calculation confirming rightness selection particular devices is here also. Autodesk Inventor Professional 2008 (chapter 3) a FluidSIM Hydraulics V 4.2 Demo Version English (chapter 4) was used as a general software.

Inovation of PUSH-PACK Machine
Šimeček, Jiří ; Vdoleček, František (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis deals with the modernization of the single push-pack machine. Modernization consists in exchanging pneumatic linear motors which are controlled by electromagnetic valves, selection of appropriate treatment of air and the design of control unit. Bachelor's thesis is divided into three parts. The first section describes the properties of compressed air and its regulation. The second part describs the original pneumatic system solutions. New solution was designed in the third part. That is used in the calculations of linear motors and air consumption,the selection of valve terminal and control system. The thesis is accompanied by pneumatic diagram.

Software for control of the velocity probe manipulator
Balusek, Radim ; Věchet, Stanislav (referee) ; Houška, Pavel (advisor)
The aim of this work is to create control software for the manipulator with three degrees of freedom used for measuring the temperature field and its activities to verify the model. Control manipulator is designed in the NI LabVIEW program. Furthermore, the work deals with the addition of the sensory system manipulator Swing. Part of this work is a description of the elemental characteristics controlled manipulators and the problem of their control is analyzed there. The practical part describes the structure of the proposal and its simulation software to verify the model.

Influence of Temperature on Mechanical Properties of Alloy AlZn4Mg.
Slouka, Marek ; Podrábský, Tomáš (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis deals with mechanical properties of a chosen aluminium alloy which is specified to preform. It is the alloy AlZn4Mg. Aluminium alloys are the most used constructive materials after iron alloys in this time. The importence of this alloys is great for their unique properties, e. g. a low density, a good corrosion - resistant, a good weldability in protective atmospheres. At first the Aluminium alloys mainly alloys of the high strength Al-Zn-Mg are described generally. Then this thesis is concerned with mechanical properties of the alloy AlZn4Mg in increased temperature. There is little information of this alloy in increased temperature in accessible scientific literature. This thesis completes the clear space in this branch.

The Study of Controllers for Four-legged Walking Robots
Klvaňa, Roman ; Věchet, Stanislav (referee) ; Ondroušek, Vít (advisor)
This work is based on literary search and is focused on description of various approaches in walking gait generation for four-legged walking robots. There are six various groups of aprroaches described in this thesis. Main functional principles as well as one representative robot of each approach is described. The summarize of advantages and disadvanteges of each approach is used to apoint an appropriate control approach for robot Quasimodo walking gait generation in the conclusion chapter of this bachleor thesis.

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.

Laboratory exercises of electronic elevator model
Kašpar, Ondřej ; Věchet, Stanislav (referee) ; Marada, Tomáš (advisor)
My Bachelor project is based on concept and realization of electronic model of elevator. This examplar works only on electric base without any mechanical components. This project at all will stay in laboratory of automatization. Students can use it as visual aid in studying and learning new things about programmable controller of Siemens, especially models S7-200. The movement of cabine of elevator is exemplified in bargraf, which you can leave control over then by active componets, LED drivers. The model is directed by micro-processor ALMEL ATmega128, which is connected with PC serial and paralel line. In my project you can find some descriptions of under consideration and used technologies, development system and constructional components.

Mechanical construction of hydraulics arm
Vodrážka, Jakub ; Březina, Lukáš (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis deals with design of a hydraulics arm. The main purpose of this hydraulics arm is the possibility to use it in education project which is a part of hydraulics systems lessons. This arm consists from few parts which are connected together by rotary joints. This arm is actuated by linear hydromotors, furthermore there is a magnetic position sensor. Autodesk Inventor 2008 was used during the arm design process. There are three main parts in this work. First part deals with fluids systems, the second part shows the position sensor properties and the last part presents some cases of arm design with deformation verify. A lot of supplement is presented at the end of this work as pictures of the model of the arm or pictures of some parts of the model.
