The study wheeled undercarriages of mobile machines
Olšovský, Petr ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The objective of this bachelor thesis is to summarize basic findings regarding various types of wheeled undercarriages that are used on contemporary machines. The first part of this paper deals with numerous requirements that should be fulfilled by the design of an undercarriage. The fulfilment of these requirements also helps to assess whether the design should be used for a specific machine. Another focus of this paper is to summarize all design solutions regarding propulsion, tyres, stabilizing elements and steering mechanisms. These solutions are compared to each other. Important design elements of wheeled undercarriages are described as well.

Design of underwater scooter
Křivan, Michal ; Karásek, David (referee) ; Křenek, Ladislav (advisor)
This thesis deals with the design of an underwater scooter, which is meant to be used by group of divers. That should be helped by a system of electromagnetic devices, through which could be smaller scooters and other equipment connected with a greater machine. The work is approached more as a design and ergonomics solution, while the construction is associated with conceptual level.

Transtibial prosthesis for recreational swimming
Křemen, Jan ; Mazůrek, Ivan (referee) ; Paloušek, David (advisor)
This thesis deals with the construction of an active transtibial prosthesis for recreational swimming. Its aim is to create a working sample of such a prosthesis. The device will primarily serve the patient to move in water - it will be attached to the stump and it will be driven forward. Secondarily, the prosthesis can be used for walking, in the sense that the patient attaches the prosthesis near to a water surface (pool, lake, ocean) and comes with it to the shore. As part of the design and electronics it will be necessary to determine the characteristics of the human resistance in water depending on speed and to determine the necessary propulsion (thrust) strength of the propeller, which will serve as the driving force. Subsequently there will be formed structural variants and selected the best one. This will become default for design and construction of simplified testing device, which will be tested for static thrust. After verifying the functionality and reliability, the final functional sample will be manufactured and tested too.

Defect detector using CIS sensor
Komzák, Daniel ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
The diploma thesis deals with the research of CIS sensors, their parameters and market research. It contains a comparison between sensors and line cameras, which are used for similar purposes, therefore in this case for scanning the packaging material. The diploma thesis contains the described construction of the device, including the assembly of components and the design of boards. The work describes in detail the image processing from the CIS sensor and various image preprocessing. There is also described method of defect detection, including their distribution and individual approach to each type of defect. The thesis contains a description of the GUI, including its functions and connection to the application dealing with image processing.

The redesign of the compressor for electromotor driving
Mikulka, Vít ; Venclík, Jiří (referee) ; Mazůrek, Ivan (advisor)
This bachelor thesis deals with redesign of the compressor for electromotor driving. First part focuses on the principle of compressors, their development and division. The next part describes a compressor MK 100 produced by Benda kompresory Ltd. company. The technical solution of its redesign for 2,2kW electromotor propulsion with maintaining a rotation speed mode of original Honda engine is explained in the last part. This compressor should be used in its redesign version at FME BUT in Brno.

Reusable launcher flight mission
Metelka, Dominik ; Daněk, Vladimír (referee) ; Zikmund, Pavel (advisor)
Tato práce je rozdělena do dvou hlavních částí, které jsou také hlavní cíle. Cílem první části je popis mise vícenásobně použitelného prvního stupně nosné rakety. V této části je nejdříve přiblíženo téma znovupoužitelných kosmických systémů a jejich vývoj do současné doby. Hlavně jsou však v této části popsány operačně používané vícenásobně použitelné nosné rakety, kde u každé z nich je poté popsána jejich letecká mise. Dále jsou zmíněny některé důležité nosné rakety ve vývoji a také jaké jsou způsoby návratu prvního stupně. Druhá část je praktická a cílem je návrh mise návratu prvního stupně nosné rakety na zemi. Pro výpočty byly zvoleny parametry podle současné rakety Falcon 9, ze kterých byla analyticky vypočtena finální rychlost a výška, ve které se první stupeň oddělí od zbytku rakety. Pro návrat a celkový let byl pomocí programu MATLAB napsán skript, který vypočítal a vykreslil potřebné parametry a charakteristiky. Díky tomu bylo také zjištěno, v jaké výšce bude potřeba znovu zažehnout motory, aby první stupeň bezpečně přistál na zemi.

Historical development of rocket engines
Šima, Dávid ; Dubnický, Lukáš (referee) ; Petrásek, Miloslav (advisor)
This bachelor´s thesis is dealing with the historic development of rocket engines and their use on rocket carriers. The work is divided into eight parts. The first part describes the principle of operation of reactive motion and derivation of the Ciolkovskij equation. The second part describes historical development from ancient China to the period before World War II. The fourth part describes the Second World War and especially the missile development in Germany during the war. The fifth part describes mainly rocket engines use in space research of the USA, Russia, Japan, the European Space Agency, India and China. The sixth part describes rocket engines of private companies which were founded in the early 21. century. The seventh part describes aerospike rocket engines and the last part describes physical engines.
