Virtual commissioning of the multi-purpose manipulator
Čech, Michal ; Vetiška, Jan (referee) ; Štěpánek, Vojtěch (advisor)
This thesis deals with the virtual commissioning of the XTS linear transport system in cooperation with an industrial robot. The theoretical part is devoted to the division of handling devices and kinematics of industrial robots. The practical part deals with the design of a demonstration task using handling devices whose movements are controlled and configured by means of a PLC using kinematic transformations. Furthermore, this part focuses on the structure of the control PLC program and HMI visualization for controlling the operation of the workplace, including the robot and XTS. The PLC program and HMI is processed in the TwinCAT 3 software environment. Finally, the functionality of the kinematic transformations is verified by virtual commissioning in the NX Mechatronics Concept Designer software.

Spatial Augmented Reality for Robotic Workplace
Štrof, Jakub ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
The focus of this work is to create projected user interface, which will complement AREditor, an application for robotic programming and also to calibrate Kinect and projector using existing calibration method. For calibration, I used the procam-calibration method, which uses projected Gray codes onto a chessboard to calculate calibration parameters. Thanks to it, virtual objects can be placed correctly into the real space. User interface was implemented using game engine Unity. By testing the interface, it was found that it helps the user to better grasp the relation between real and virtual space when placing virtual objects into the robotic workplace. It also raises user's awareness of the robot's movements when cooperating with it.

Design of dosing unit for sanding of rail vehicles
Szabari, Šimon ; Čížek, Petr (referee) ; Omasta, Milan (advisor)
This master thesis deals with the development of a sanding unit for rail vehicle. The aim is to develop a dosing device capable of applying sand to the contact of a wheel and a rail depending on the speed of the vehicle with the detection of the flow rate of the applied amount. The application of sand or alternative materials to the wheel-rail contact is an effective way to increase the traction of driving rail vehicles. During the development, there was a cooperation with a company engaged in the production of equipment for rail transport. During the work, experimental development was applied, during which a pneumo-mechanical dosing unit with control of the applied amount of sand was designed and tested. Simultaneously with the dosing unit, a sand box was designed that is suitable for the type of rail vehicle for the purpose of tests in real operation. The pre-prototype design has the potential to bring improvements in several areas of sanding systems.

Technical-economic framework for the integration of individual and community electricity generating plants
Vaculík, Tomáš ; Radil, Lukáš (referee) ; Drápela, Jiří (advisor)
In conection with current energy situation, efforts to achieve energy self-sufficiency are increasing in the Czech Republic and the rest of the Europe. Renewable energy sources can already be used within households. However, not everyone has the opportunity to purchase and operate such a factory. The solution to these problems may bet he increasingly discussed community energy, which is becoming more popular in the Czech Republic in connection with changing legislation and financial motivation in the form of various grants and subsides. The purpose of this work is to create a summary of the most important information of the technical and economic framework and subsequent creation of an easily modifiable and parameterized model of energy communities, which will show the technical properties of individual connections, such as power losses or the influence of metrics on the resulting values of measured energy.

Syntaktická analýza založená na spolupracujících gramatikách
Nehéz, Patrik ; Havel, Martin (referee) ; Meduna, Alexandr (advisor)
This thesis deals with the issue of grammatical systems and syntax analysis. Thesis presents cooperatively distributed and parallel communicating grammatical systems. Thesis describes my design of grammar system and which works on the basics of CD grammar systems and than it shows my implementation. The result of this thesis is application that uses bigger number of components that works together and it combines both methods of syntax analysis.

Materials prohibited in the space industry
Mindl, Ondřej ; Štěpánek, Roman (referee) ; Vydra, Pavel (advisor)
This bachelor's thesis focuses on materials prohibited in the space industry. The selection of materials to be used in space program applications is influenced not only by structural requirements but also by factors specific to the industry. This work focuses on providing a detailed description of these factors, limitations, and prohibitions, with the main source of information being the standards developed and issued by the European Cooperation for Space Standardization (ECSS) for the aerospace industry in Europe. The extensive database of standards has been carefully processed, and the selected information has been summarized into a single document intended to facilitate a more efficient selection of suitable materials for space industry applications.for more efficient iteration in the selection of suitable materials.

DESIGN AND APLICATION OF COLLABORATION ROBOTS
Mecera, Martin ; Vetiška, Jan (referee) ; Knoflíček, Radek (advisor)
The bachelor's thesis deals with the analysis of the current state of construction and application of collaborative robots. Thanks to the comparison of cobots and traditional robots, the strengths and weaknesses of cobots are found. The work describes the influence of the requirement for safe cooperation with humans on the construction of cobots, end effectors, and suitable applications of cobots in industry. Mezinárodní strojírenský veletrh 2023 is the source of modern applications presented in this thesis. The system analysis of the issue of robotization with cobots describes the contribution of cobots to automation. The analysis of the structure of the system with a cobot, the influences of the environment on this system, and the description of the life cycle of the cobot allow estimating the productivity of the cobot in a given application. The work introduces the concepts of Industry 4.0. It compares predictive maintenance of cobots with the maintenance of other machines. It presents applications of cobots with a significant representation of the principles of Industry 4.0. The work provides recommendations concerning the research of cobot construction, the use of artificial intelligence in teaching cobots, and recommendations for applying the principles of Industry 4.0 in the transformation of a traditional factory into a smart factory.

Taxation of natural persons
Šobáňová, Veronika ; Ing. AdrianaLibičová (referee) ; Svirák, Pavel (advisor)
This bachelor thesis deals with the optimization of income tax of a selected natural person including social and public health insurance payments. The theoretical part describes the terms and methods for calculating the tax liability. In the practical part, a chosen natural person is described followed by a description of several options for optimizing the tax liability. The result is a successful reduction of the overall burden on the household. The calculations are always based on maximising the person’s disposable income.
