Educational Nanosatellite in PocketQube Format
Lokaj, Jakub ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
Hlavním tématem této diplomové práce byla teoretická analýza současných trendů ve vývoji nanosatelitů, konkrétně se zaměřením na formát PocketQube a jeho aktuální implementaci. V jednotlivých teoretických kapitolách se práce zabývá možnostmi a výhodami využití PocketQube jako výukového modelu pro vzdělávací a vývojové oblasti. Zabývá se také možnostmi 3D tisku nosné konstrukce družice a rozebírám jednotlivé komponenty, jako je palubní počítač, komunikační systém založený na technologii LoRa, napájecí systém a přehled subsystémů. V praktické části byl vyvinut rám družice, jednotlivé části struktury elektroniky PocketQube a implementace základní funkce komunikace a provozu pro vzdělávací model PocketQube.
Production of a working replacement part of a blender using the FDM printer
Bruštík, Adam ; Kupčák, Radim (referee) ; Zemčík, Oskar (advisor)
This Bachelor thesis is devoted to designing variants of kitchen appliance gearing, subsequent production via FDM 3D printing method and the evaluation of its technical and economical aspect. The research in a theoretical part briefly describes an issue of worm gears and FDM method. The selection of the most suitable variant is assessed on the basis of the results achieved with FEM.
Robotic Arm Exploiting RC Components and Servos
Bobčík, Petr ; Kapinus, Michal (referee) ; Zemčík, Pavel (advisor)
Cílem této práce bylo postavit vlastní robotické rameno, s využitím RC komponent, serv a dodat k němu i vlastní uživatelské rozhraní, které umožní jeho řízení. Součástí řešení bylo také opatřit robotické rameno potřebnou senzoriku, která by umožnila jistou míru autonomnosti. Pro mé řešení jsem se rozhodl upravil již existující design robotického ramene, s pěti stupni volnosti, založeném na krokových motorech. Přidal jsem senzory, jako je akcelerometr, enkodér, měřič proudu, laserové měření vzdálenosti a kameru. Na základě těchto senzorů je robotické rameno schopné detekovat náraz, pozici odpojených motorů, uchopení předmětu uchopovacím mechanizmem nebo měřit vzdálenost předmětu v prostoru za účelem inverzní kinematiky. Vytvořil jsem také jednoduché uživatelské rozhraní, které umožňuje tři typy ovládání, jako je ovládání jednotlivých kloubů samostatně, autonomně s využitím kamery nebo ručním napozicováním.
Design of linear clock
Firla, Marek ; Malý, Martin (referee) ; Svoboda, Petr (advisor)
The main goal of this thesis is to describe the design, construction, and manufacture of linear clocks. The first part describes the current linear clocks design. The second part describes the design of a linear clock prototype. The linear clock is controlled by an Arduino UNO microcontroller unit, the time is measured by the real-time module, the movement of the time indicators is mediated by a pair of stepper motors. Manufacture is done using 3D printing.
A proposal and manufacturing of temporary dental restoration
Jiroušek, Jan ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This bachelor thesis deals with manufacturing of temporary dental restoration. Theoretical part contains an overview of types of dental restorations and their division, Furthermore it states important properties and division of the dental materials used nowadays. The next point of theoretical part is an overview of the technologies of dental restorations manufacturing used at present. Practical part is aimed at manufacturing of temporary dental restoration by using the digitization by intraoral scanning, design of restoration in CAD software and CAD/CAM manufacturing. The thesis is concluded with discussion comprising a summary and evaluation of the results of single steps from practical part.
Design and production of experimental axle part
Volfík, Jiří ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The content of this diploma thesis is a design of construction and selection of suitable material for upper-carrier part used for racing vehicle, produced by FDM 3D printing with the alternative option to replace an existing part, which was produced by conventional technique of CNC machining. Various versions of the experimental part are analyzed by FEM and compared in terms of safety coefficient with target to select the most appropriate construction design. The chosen version of the model is at the end compared with already existing part, which was also analyzed by FEM.
Robust wheeled robotic chassis
Jirges, Radek ; Chalupa, Jan (referee) ; Bastl, Michal (advisor)
This thesis deals with the issue of the proposal of mobile wheeled robotic chassis. In the introductory theoretical part gives an overview of the division of mobile chassis inclu-ding representatives of each group. In the begining of the practical part describes se-lection of suitable components for the chassis from drivetrain to controlling electronics. Constructional part of this thesis at first deal with selection of suitable material for each part of chassis and than follows construction of these components including decsription of used constructional solutions for each issue. Result of this thesis is robust wheeled chassis fitted with drivetrain and basic electronics.
Lighthouse for maritime communication
Chadima, Jan ; Mašek, Pavel (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with design and construction of lighthouse model, which will be used for teachning. It describes types of naval signalizacion, which are established by organization IALE in decree E-110. In thesis is described Arduino platform, metods of 3D printing and used materials For model needs was designed printed circuit board with microcontroller ATmega328P, which control RGB LED. Program, which control model, was writed on Arduino platform. Program has nine modes of sea light comunication. It can change periode, color of LED, brightness and turning on power saving mode. The result of this work is a functional model of lighthouse powerd by battery. Model is based on Green Cape Lighthouse in Australia in scale 1:58.
The comparison of 3D printing technologies and the subsequent production of a component
Čuma, Zdeněk ; Sedlák, Josef (referee) ; Jaroš, Aleš (advisor)
The objective of the thesis is a comparison of 3D printing technologies. The essence of 3D printing is described and its individual methods are analyzed in the first part. The second part is focused on the construction of a real component – a suction branch. Other practical parts focus on the production of the component itself using various 3D technologies and subsequent comparison of the printed models.
