3D printed microscopes
Žáková, Veronika ; Jákl, Petr (referee) ; Dostál, Zbyněk (advisor)
Modular microscope building kits allow those interested in microscopy to get a hands-on introduction to the construction of a light microscope. For this reason, it would be appropriate to equip the laboratories of the Institute of Physical Engineering at Brno University of Technology with such a kit. The inspiration can be found in the open source project openUC2, which offers optical kits based on a combination of 3D printed and commercially available optical components. The aim of my work is to use the open source parts database and supplement it with my own designs that would enable the construction of specialized polarization and fluorescence microscopes. The first part of the thesis introduces light microscopy methods and the equipment that is essential for their proper operation. Next, the 3D printing methods that are applicable to the fabrication of the designed parts are summarized. Beyond the openUC2, the design of a Köhler illuminator, a motorized stage and a motorized objective slider based on commonly available parts are introduced. A transmission microscope, a reflective polarizing microscope and a light sheet microscope were designed based on the UC2 kit with my construction modules. The first two have been assembled and tested along with their control software.

Floating Robot KAMBoat II
Beneš, Jiří ; Žalud, Luděk (referee) ; Kopečný, Lukáš (advisor)
Objective of this thesis is to design and create second generation of KAMboat type robotic ship. Main tasks are to test abilities and performance of the ship alone and in comparison with the previous model. This thesis is divided into subparts which compare the differences between the two prototypes. First chapter focuses on analyzing selected parts of ship’s physical model, especially the hydrodynamics, which is then used to define construction limits. Following chapters KAMboat 1 and Construction analysis describe the first version of ship and reasons of making new version. Chapter KAMboat 2 refines the theoretical knowledge gained in previous chapter into tangible form. Chapter Electronics describes selected electronic equipment of the ship and mounted circuitry. The Control chapter is focused on combining theoretical and practical aspects of driving a small BLDC engine. Controls and Communications chapter describes how to secure and maintain data flow between operator and the robot. Chapter Missions is selection of tasks that are supported on KAMboat 2 type robotic ship.

Interpretace tradičních strukturálních principů v konstrukcích dočasného charakteru
Joja, Marie
The paper focuses on traditional structural principles of historical buildings of the era 18 to 19 century in the Znojmo region, which are also included in the project „Identification and interpretation of origins, forms and transformations of Baroque cultural landscape of the South Moravian Borderland“. The aim of this work is to describe traditional roof frames of selected historical buildings of the area. The goal of the work is to find a suitable construction detail applied in the traditional roof frames, which would be used for a structure of temporary character. Temporary structures are associated with transient functional use, which can be one of the possible phases in the planned restoration of abandoned sites. The existence of many examples at the international level demonstrates successful redesign of dilapidated buildings by the use of temporary programme. The analysis of traditional structures proposed a suitable structural joint for a design of a modular element for the construction of temporary architecture. Its characteristic is the low-cost production and simple construction, which can be relocated to other places and adapted for further use. The significance of the work lies in the design of elementary structures of objects of a transitory nature, which are based on the traditional building principles of historical monuments and try to preserve structural uniqueness of the architecture.

Tracked chassis of a forwarder
Svoboda, Jan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The thesis describes the design of a modular track undercarriage system for a forest utility vehicle called the forest forwarder. In the introduction there is a research study which reviews a variety of design options. The main part of the thesis describes the 3D model created in the Catia V5 programme. The model was subjected to an analysis of dynamic effects by simulated use of the track undercarriage system in the MSC Adams programme. A selected part of the undercarriage was analyzed by the finite element method in the Ansys Workbench programme. Drawing documentation of some of the components is included at the end of the thesis.
