Design of a 3D scanner for educational purposes
Paprsek, Adam ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
The aim of the submitted semestral project is research of 3D scanning object methods. The 3D scans utilization and types of these scans have been mentioned in the first chapter. The scanners are grouped into two basic methods – contact and contactless. The second chapter is dedicated to 3D model measurement principles, which are described in detail in four sub-chapters. In the following chapter is described design with complete realization 3D scanner with the implementation of the application for its controlling. Last part of the thesis concerns the 3D model editing and method evaluating.

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.

Calibration unit for spirometer
Burian, Tomáš ; Máca, Josef (referee) ; Vyroubal, Petr (advisor)
The task of the semester project was to become acquainted with methods of calibrating the spirometer and creating a calibration unit. Calibration unit must be able to calibrate both by volume and by speed. Because of that, the manual calibration of calibration cylinder is provided with a stepper motor mounted to the cylinder piston. The designed PCB will also be controlled by a program to control a stepper motor. The control system will contain 16 different options of selecting the speed of the piston

Robotic hand controll using virtual reality
Sláma, Pavel ; Bílek, Michal (referee) ; Vyroubal, Petr (advisor)
This bachelor thesis deals with possible solution of controlling robotic hand with virtual reality. To realize this work is used a prosthetic hand from the InMoov project. This thesis describes basic principles of 3D print technology and deals with materials suitable for manufacturing of a chosen robotic hand. As next describes function and controlling of servos, hand control using prototyping platform Arduino communicating with the computer with MyRobotLab software support. To capture movement is used motion sensor for virtual reality Leap Motion.

Magnetic field measurement
Dušek, Jiří ; Máca, Josef (referee) ; Vyroubal, Petr (advisor)
Bachelor thesis describes ways and technology for measuring of the magnetic field. Furthermore it deals with comparing sensors for magnetic fields measuring and creating a basic conception of the meter. For design of conception was selected sensor HMC2003 from Honeywell company. Design of conception describes two units, which meter contains. Conception include power, compensation and reset circuits. After that is detailed describe layout of both printed circuit boards, setting up and soldering components. Output of this meter is signal of the three axis of sensor. Meter was subjected to trial run, which verified functionality of the whole device.

Mapinng and improving logistic flow in the firm ZEBR.
Kmeť, Lenka ; Vyroubal, Petr (referee) ; Špinka, Jiří (advisor)
The aim of the project is to chart the course of logistics and information flows of the selected company, to eveluate the entire process and to find improvements. In the first part there is mentioned an introduction into methods of lean manufacturing, value stream mapping and throughput time calculations. In the next section the flow of values is mapped and the map of current state is created. Futhermore, the throughput time of selected parts is computed and the mounting diagram of measured products is assembled. On to these materials are founded the sources of wasting and solutions are suggested. Afterwards on the basis of the obtained data are given solutions eveulated in terms of economic indicators.

CNC router for PCB
Gerják, Rastislav ; Vaculík, Sebastian (referee) ; Vyroubal, Petr (advisor)
In mechanical industry, both additive and subtractive manufacturing methods are controlled by instructions in G-code, making it possible to utilize both technologies in one modular device. Main objective is to design, construct, and calibrate multipurpose machine based on RepRap 3D printer, which will be able to use attached spindle to precisely mill light materials. Particular emphasis is given to ability to carve a pattern and drill holes in plated substrate in order to create functional PCB by incision.

Modelling of lithium ion batteries using ECM
Langer, Lukáš ; Kazda, Tomáš (referee) ; Vyroubal, Petr (advisor)
The main aim of this paper are models of Li-Ion storage batteries made and simulated in ANSYS Fluent software. Various ways of simulations are discussed with main aim on ECM method and how its numerical model is computed. A process of getting information and required data from real battery to be compared with simulation results by EIS method is also discussed. These results are then compared with results from ANSYS Fluent.
