Europe's strategy for Tech Security in the Era of Raw Critical Materials
Štěpánek, Vojtěch ; Karásek, Tomáš (advisor) ; Bureš, Oldřich (referee)
This diploma thesis is a single case study focusing on the European Union's approach to the issue of critical materials as a security concern. Critical raw materials will play an increasingly important role in Europe due to the ambitious Green Deal policy. The technologies necessary to address environmental challenges require a significant share of materials identified as critical in Europe. However, the problem is that most of these materials are concentrated in unstable and undemocratic regimes, which may pose strategic rivals. This creates a threat that supplier states may use critical materials as a tool of power and thus jeopardize the economic security of European Union countries. This thesis examines critical materials as a phenomenon, analyzes their criticality and relationship to technologies. It further conducts an analysis of selected critical materials and their risks, particularly about the nature of supplier states. The final chapter addresses the European strategy in this area and describes how critical materials affect strategic technologies.

Even though commissioning of new production system is costly and time consuming, it is vital part of innovation, optimalization of processes and in maintaining competitive advantage. This thesis is focused on, virtual commissioning of production system for assembly of FEIFER‘s manual strapping machine BO – 7 SWING. In the first part of the thesis, information regarding the thesis is described, following is transformation of the 3D model to model suitable for simulations. Production system is analysed and described. The last part of the thesis focuses on creation of control program and virtual commissioning itself.
Design of a weighing unit for an automatic phenotyping line
Mikuš, Martin ; Věchet, Stanislav (referee) ; Štěpánek, Vojtěch (advisor)
The purpose of this master thesis is the design and realization of a weighing and watering unit for an automatic phenotyping system. The master thesis is structured into several phases. Firstly, a market survey of available control systems for unit operation is conducted, followed by design of conceptual solutions and selection of the most suitable design. Subsequently, the design is optimized and appropriate components are selected for implementation. Finally, the weighing and watering unit itself is implemented and thoroughly tested.
Design of an industrial robot with six degrees of freedom
Štefek, Ondřej ; Štěpánek, Vojtěch (referee) ; Knoflíček, Radek (advisor)
The diploma thesis deals with the design, production and construction of robots with six degrees of freedom and a serial kinematic structure. In the beginning of the thesis, the individual types of robots, used gearboxes, energy media are described, and the principle of direct and inverse robot kinematics is outlined here. In the next chapters, the system approach of the robot, the selection of the optimal variant of creation, and then the kinematics and dynamics of the robot, which further follows on from the principle of the creation of castings, the design nodes of the robot and its electrical engineering and the programming of the control system, are analyzed. For the pinions and the shaft of the fifth axis, a safety analysis is carried out with respect to the limit state of elasticity. This robot design is then financially compared with a commercially available industrial robot. For the robot, among other appendices, drawing documentation, an electrical wiring diagram and a safety analysis of the robotic workplace have been prepared. The robot and the related robotic workplace are physically built in the workshops of the Institute of Production Machines, Systems and Robotics in Brno.
Virtual commisioning of one purpose production cell
Vala, Martin ; Bražina, Jakub (referee) ; Štěpánek, Vojtěch (advisor)
Master thesis deals with the issue of virtual commissioning and PLC programming. In the first part of the thesis a research in the field of control systems and softwares for virtual commisioning is conducted. The second part of the thesis deals mostly with NX Mechatronics concept designer software, where the initial modification of the model and its configuration for virtual commissioning takes place. The actual preparation of the model is followed by the virtual connection of the TwinCAT 3 control system and previously mentioned NX MCD using a virtual OPC server. The control program code is then created using the TwinCAT 3 development environment to control the assembly operations. This is followed by the actual virtual commissioning of single purpose station for assembly of the steel strapping machine.
Virtual commissioning of the robotic clock
Dvořák, Jan ; Tůma, Zdeněk (referee) ; Štěpánek, Vojtěch (advisor)
Anna Barcuchová The aim of this thesis is virtual commissioning of a digital twin of a manipulator working as a robotic clock. The thesis contains a research of PLC control systems with a focus on motion control, conceptual design of three versions of the solution of the task, flowcharts of the control algorithm and description of the creation of the digital twin in NX Mechatronics Concept Designer. For the final version of the solution, calculations were made for determining the maximum angular acceleration of the individual robotic arms. Included in the thesis is also a control program for TwinCAT 3.
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.

Development of water show control
Havran, Lukáš ; Pruša, Radomír (referee) ; Štěpánek, Vojtěch (advisor)
This thesis deals with the design methodology for controlling a digital water curtain. The research section focuses on analyzing control systems suitable for this technology and on software tools that enable the implementation of a user application designed to control the water curtain. Based on the research, the practical part involves the implementation of a user application for composing and executing water scenes. Another aspect of the practical part is the selection and programming of control hardware that manages the water jets. The control principle relies on communication between the user application and the control hardware. The practical part is further complemented by the construction design of the digital water curtain in the form of a 3D model, which includes all construction elements, including the control hardware.
