Multifunctional modular FDM 3D printer
Indra, Zdeněk ; Vyroubal, Petr (referee) ; Jaššo, Kamil (advisor)
This work deals with problems of 3D printers, their types according to function principle and their design. In addition to print materials, FDM printers chapter includes the types of motion systems available for FDM 3D printing, and the possibility of converting 3D printers to other CNC devices is discussed. This theory is then evaluated and the most suitable parts are used to build modular CNC machine wich is then tested in configuration of FDM 3D printer.

Design of a semi-automatic positioning system for measuring of semiconductor chips
Kotian, Tomáš ; Vyroubal, Petr (referee) ; Otáhal, Alexandr (advisor)
The aim of this bachelor thesis is to design and create a system for a semi-automatic positioning system for the test of semiconductor chips. The work solves the problem with the implementation design to achieve the highest possible accuracy for contacting with the help of a probe card. Furthermore, the work deals with the selection of a suitable control unit for stepper motors and finally to create a program for focusing and centering the chip using the image from the camera.

Welder for lithium batteries
Martinček, Martin ; Jaššo, Kamil (referee) ; Vyroubal, Petr (advisor)
This Bachelor’s Thesis deals with the composition of lithium batteries, lithium cell joining, and the design of a device customised for contacting an 18650-size cylindrical cell. The first part discusses the construction, basic materials of the lithium batteries and their applications. In the next section, an overview of several methods of cell contacting and their comparison with each other is presented. The last section discusses different parts of the design and construction of the device, working on the principle of spot resistance welding.

The Internet of Things in Practice
Bajgl, Vojtěch ; Vaněk, Jiří (referee) ; Vyroubal, Petr (advisor)
The subject of this diploma thesis, is the Internet of Things, and its use in applied practice, with a subsequent design of a custom system of smart home automatization. It acquaints the reader with the issues of automated home and smart systems, including a basic familiarization of regulations as declared by law about electronic devices. The attributes of miniature computer platforms, developmental boards, and wireless modules for the design of custom systems are analyzed and compared. The biggest part of the thesis is dedicated to a design of a custom system, specifically designing the central processing module and other controlling modules for controlling various electric home appliances. The main controlling unit of the system is a Raspberry Pi 2B unit, with which it is possible to control a device in a household through an user-friendly web application.

Rotary table for 3D scanner
Suchý, Lukáš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master thesis deals with the 3D scanning. This thesis explain methods of reversal engineering with a special aim for technical disciplines. Also some examples are being given. Next part deals with the 3D scanning technology and focuses on separation of scanners to a different groups and associated technology. Basically the scanning methods are separable to destructive and non-destructive groups. An images are obtained by 3D scan, its problematics and z-axis acquisition follow in next part of the thesis. Afterwards some key parameters suitable for selection of scanning systems are selected. A scanner "David SLS2" and its basic parameters, manipulation, service and calibrating process is being described. Last part deals with function and construction of rotating table used together with the 3D scanner David SLS2.

Construction scintillation detector with one aperture for environmental scanning electron microscope
Přichystal, Vít ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
The thesis is focused on the design of a scintillation detector with one screen for environmental scanning electron microscope. At the beginning of the work is an introduction to microscopy. Further work is focused on the description of ESEM microscope and a scintillation detector. The following chapter is devoted to the dynamics of flow. They list the types of flow and mathematical description of equations. The next chapter is about using the software and the way of solution of flow. In the following chapter describes a proposal of the diaphragm and extraction method of the detector area. They are described some of type aperture. The last chapter is the conclusion, where the work is summarized.
