Sheet thickness optimization of the bolted steel tank
Konečný, Jiří ; Lyčka, Petr (referee) ; Skalka, Petr (advisor)
This thesis deals with bolted steel tanks, especially modification one of them. This modification is realized in cooperation with Kohimex spol. s r.o., which is assembling theese tanks for many years. The thesis continues on the bachelor one called "ASSEMBLED STEEL TANKS", which has already dealt with this issue. At the beginning of the thesis the issue of tanks is explained. Furthermore, there is made description of the tank modification details. At the next stage, the work presents stress-strain states of the tank, first for the current tank and then for the modified option. On the basis of completed analysis is made economic evaluation of design modified tank option due to the current tank. The results of this study allow better issue understanding of bolted tanks designing or they give impuls to improve the current way of designing.

Design of a Robotic Cell for Flat Parts Production
Závodský, Martin ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
This master’s thesis deals with the design of a robotic cell for the automation of woodworking machine tending. The task of the robot is to manipulate with the specified laminated chipboards of various sizes, before and after machining. The boards are brought to the cell on pallets in three possible placement variants. After a brief research part, conceptual designs of cell layout were created. The optimal and further elaborated design came as a result of selected evaluation criteria. The next part of the thesis consists of designs and selection processes of individual components. These were later used to create a simulation model in Tecnomatix Process Simulate software (Siemens), that helped to verify the functionality of the cell layout, design the control logic and acquire the time of the manipulation cycle used for informative calculation of annual production. In the end, the final design was evaluated from an economic point of view with an emphasis on the return of the initial investment.

Design of photovoltaic power plant for flat house
Holuša, Martin ; Topolánek, David (referee) ; Morávek, Jan (advisor)
The aim of this bachelor thesis is to develop a design of a photovoltaic power plant for a given flat house. The theoretical part deals with the basic components of a photovoltaic power plant, its legislation, the possibilities of supplying electricity to other entities and the creation of variant concepts of the photovoltaic power plant itself. In the practical part, the concepts are economically evaluated using a parameterizable form and for the selected variant is created project documentation for its implementation.

Robotic machining of composite materials
Rubišar, Václav ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
This thesis deals with the robotic machining of composite materials. It is divided into two main parts - theoretical and practical part. The theoretical part is focused on detailed introduction of the term “an industrial robot” and a description of its controls, types of the robots, types of their propulsion and programming methods. Furthermore, there is a list of CAM softwares with its specification designed for both conventional machining and machining by using a robot. It also includes the introduction of composite materials and specification of their machining. The practical part deals with selection of appropriate type of bracket spindle by using a simulation software, suction design and economic evaluation of two types of machining in manufacture.
