Design of end effectors for a robotic cell
Hirsch, Radim ; Štěpánek, Vojtěch (referee) ; Tůma, Zdeněk (advisor)
This thesis is focused on the structural design of end effectors for the ABB IRB 4400/60 industrial robot within the robotic cell in the laboratory of the Institute of Production Machines, Systems and Robotics. The first part of this thesis is focused on detailed research in the field of manipulation end effectors and systems for automatic exchange of end effectors. The next chapters offer a system breakdown and an analysis of the effectors currently used. The following two chapters discuss the design variants of the new solution, which are evaluated using multicriteria analysis. The design chapter describes the implementation of the new automatic end effector exchange system and offers a description of the newly designed effectors, based on verification calculations, as well as robot load analysis for each effector. At the end, an economic evaluation, discussion and evaluation of the proposed structure and conclusion are carried out. This work includes 3D models of the end effectors, their stand, as well as drawing documentation, including a pneumatic connection diagram.

This thesis deals with optimalization of already existing design of belt grinder on basis of trial operation and design based on optimalization. In the research part are mentioned basics of grinding and categorization of belt grinders. In next part, the reader is introduced to existing design. Following by analysis of flaws and part about optimalization, where flaws are resolved, and new optimised design is checked by engineering calculations.
A design of engraving plotter
Brtník, Vojtěch ; Tůma, Zdeněk (referee) ; Tůma, Jiří (advisor)
This bachelor thesis, in addition to the actual design of the laser engraving laser, contains basic information about laser engraving technology and marking used in industry. It explains the physical principle of the laser and the laser source, which is essential to understand and classify laser modules. Provides an up-to-date market survey of the laser engraving modules and engraving plotters in use. In the design part, the design of an engraving plotter for SMC company is carried out using 3D models in Solidworks 2022 according to the specified parameters. The plotter design includes the selection of a suitable linear motion unit with electric drive, the assumed control, control calculations and the design of the plotter structural elements. The next section deals with the design of the support part and includes safety and functional elements. The paper concludes with a cost evaluation and recommendations for practice.
Welding manipulator construction design
Fuks, Šimon ; Tůma, Zdeněk (referee) ; Štěpánek, Vojtěch (advisor)
This bachelor thesis deals with the design of a five-axis welding manipulator as an additional device to a welding table. The research focuses on knowledge from arc welding automation, especially on the use of industrial robots and manipulators in this area. A rich selection of accessories for robotic arc welding is also summarized. In the practical part, several conceptual variants are proposed, and the most suitable variant is further developed. The basic technical calculations of the manipulator are presented and the individual construction details are discussed. Furthermore, the work deals with the safety and control possibilities of the designed manipulator. The work also includes a drawing of the overall assembly.
Financial Performance of European Cooperative Banks
Kuc, Matěj ; Teplý, Petr (advisor) ; Tůma, Zdeněk (referee) ; Tripe, David (referee) ; Witzany, Jiří (referee)
This dissertation consists of four essays dealing with the financial performance of European cooperative banks. We focus on a comparison between the performance of cooperative banks and that of shareholder-owned commercial banks. Furthermore, we compare different cooperative banking models in Europe, paying special attention to the Czech credit union sector. In the individual essays, we examine different performance measures depicting profitability, stability and cost efficiency. The topic of the financial performance of cooperative banks is highly relevant, as cooperative banks are structurally different from the standard commercial banking model and they have a significant market share in several European countries, while most of the empirical literature focused on banking financial performance is devoted solely to commercial banks. The first essay of this dissertation thesis empirically assesses the financial performance of Czech credit unions compared to that of cooperative banks from 15 European countries in terms of their profitability and stability. Employing dynamic panel data methods, we reveal that the performance of Czech credit unions in terms of both profitability and stability is worse than that of their European peers. In the second essay, we compare the financial performance of cooperative...
Bank's performance in low and negative interest rate environment
Hanzlík, Petr ; Teplý, Petr (advisor) ; Tripe, David (referee) ; Witzany, Jiří (referee) ; Tůma, Zdeněk (referee)
Dissertation thesis Banks' performance in low and negative interest rate environment Author: Mgr. Petr Hanzl'ık Abstract This dissertation consists of four empirical papers that focus on the performance of banks in the low or even negative interest rate environment characteristic for the decade after the global financial crisis of 2007-2009. The first paper focuses on the analysis of a re- lationship between the net interest margin (NIM) of EU banks and market interest rates in a low-interest rate environment while controlling for the impact of market concent- ration by examining a large sample of annual data on 629 banks from EU countries for the 2011-2016 period. The results show a positive concave relationship between NIM and short-term interest rates, deterioration of NIM for all types of banks and a higher market concentration leading to higher NIM. In the second paper, we examine the determinants of NIM of European and US banks in a zero lower bound (ZLB) situation while control- ling for institutional design factors, i.e. difference between capital-based and bank-based financial markets. We analyse a large sample of annual data on 629 European banks and 526 US during the 2011-2016 period confirming that NIM is significantly influenced by the different institutional designs. The third paper deals with...
Design of a small lathe for wood
Mečíř, Václav ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The bachelor's thesis describes the design process of a small wood lathe. The proposal itself is preceded by acquaintance with the issues and technical possibilities of this time. This is related to market research and comparison of individual lathe variants, with respect to the required machine parameters. The subsequent design contains a calculation report in which the transmission system and the spindle design, on which the greatest emphasis is placed, are solved, as it is the most important part of the lathe. Based on the calculation report, a 3D model and drawing documentation is created in Inventor 2021.
Design of end effector for a robotic cell
Machala, Lukáš ; Pavlík, Jan (referee) ; Tůma, Zdeněk (advisor)
This Master´s thesis deals with the design of end effectors for object manipulation within robotic cell located at the Department of Production Machines, Systems and Robotics, Brno University of Technology. The theoretical part of the work is devoted to a summary of the current state of knowledge in the field of end effectors. The practical part deals with draft of several variants of the solution, from which is chosen optimal variant by the method of multicriteria analysis, after which follows the construction of individual end effectors. The work includes individual 3D models of these end effectors and a rack for their storage, the work also includes assembly and part drawings. The work ends with an economic evaluation, discussion of achieved results and a conclusion.
