Digitization of teaching models
Dvořák, Tomáš ; Kaczmarczyk, Václav (referee) ; Sýkora, Tomáš (advisor)
This thesis focuses on the digitization of laboratory fixtures Case Sorters and Drills. These laboratory fixtures were assembled within the framework of bachelor theses from previous years for teaching at the Brno University of Technology. The thesis deals with the digital twin, one of the concepts of Industry 4.0. It is a technology that enables the digitization of physical reality for monitoring, simulation and prediction. It is a trend that is already used in many applications not only in industry. This work shows the conversion of laboratory preparations into digital form in order to simulate physical operation and subsequent testing on physical equipment. The models are controlled via the TIA Portal from Siemens in Ladder language.
Use of laser scanning in heritage buldings
Müller, Jan
In the case of heritage buildings (and not only in their case), the problem is often the absence or outdated drawing documentation. In recent years, instead of the traditional surveying of buildings with the help of onedimensional tools (whether we mean a tape measure or a laser rangefinder), three-dimensional surveying using laser scanning, in which a virtual spatial copy of the object is created with the help of millions of points, the so-called point cloud, has been slowly gaining ground. This cloud or clouds can be used to create 2D and 3D documentation of the existing state of the building with much greater speed, accuracy and clarity than conventional methods. Currently, the two most widely used methods of laser scanning using so-called LIDAR are the static method, using fixed stations, and the dynamic method, using modern technology in the form of precision IMUs. The paper describes the principle of these two methods, their advantages and disadvantages and also the way of working with point clouds created in this way. Unfortunately, the greater spread of virtual representations of real objects created in this way is hindered by the higher purchase price of the necessary instruments, but already today their cost is many times lower than in the recent past and in the foreseeable future they could hopefully be available to all who would need them in their activities. The article also includes examples of point clouds as well as examples of the outputs they have produced.
Methods for Design of Virtual Twin of a Dynamic System
Kšica, Filip ; Novotný, Tomáš (referee) ; Holub, Michal (referee) ; Hadaš, Zdeněk (advisor)
Over the last decade, digital twins and cyber-physical systems have been slowly developed from mere theoretical concepts to potent industrial applications in a large spectrum of areas, however, ambiguous understanding of the fundamentals significantly complicates the process of finding a general methodology necessary for their successful implementation. Therefore, one of the main goals of this thesis is a systematic study of these concepts and their main parts, followed by formulating a methodology that could lead to successful and effective industrial applications in the context of current projects. The key part in this effort falls to computational modelling and dynamic reduction of complex mechanical systems that comprise the digital part of a digital twin, including but not limited to the main structure but also sensing systems. These sensing systems serve as cyber-physical systems that fulfill the role of interactive links between the individual parts of a digital twin and are introduced in the last part of this thesis in the context of manufacturing industry, airspace, and railway industry, where they are used not only for condition and operational monitoring, but also provide large amount of accurate real-time data for structure health monitoring and predictive maintenance purposes.
Use of Modelling and Simulation in the Analysis of Operational Risks of Production Lines
Wolker, Jakub ; MSc, Martin Manga, (referee) ; Lacko, Branislav (advisor)
The diploma thesis deals with the use of modeling and simulation in the analysis of operational risks. Proposals for the methodology for creating a digital twin model of new and existing production lines, subsequent verification of the methodology on a specific model and also the use of the model to determine operational risks will be presented. Siemens Tecnomatix Plant Simulation software is used to create the digital twin model and to verify risk scenarios and related experiments. The main goal of this work is to propose a suitable procedure and means that address the issue of planned benefits and risks for production line projects. This is achieved by meeting the sub-objectives that correspond to the individual proposals. The solution is based on theoretical knowledge and analysis of the assembly line, the state of value stream mapping and the data used.
Use of Head-mounted displays in risk management for machine tools
Jelínek, Martin ; Kotek, Luboš (referee) ; Tůma, Zdeněk (advisor)
This diploma thesis deals with the design and technical possibilities of VR headsets and their application in mechanical engineering, specifically in the field of risk management in machine tools, using experience from other areas and history. The practical part of the thesis comprises a risk analysis carried out on a single selected machine (vertical machining center) by means of checklists and virtual technologies. The risk analysis techniques used are subsequently compared and evaluated. The results are then assessed and a proposal for the use of virtual reality in practice is put forward.

The introductory part provides a brief insight into the field of digital twins in Industry 4.0 and the approaches by which machine components are modelled. Other parts of the thesis focus on the MapleSim tool. In the last part, a custom digital twin is created using MapleSim and Automation Studio tools.
Digital twin of a conveyor line
Sazonov, Viacheslav ; Lacko, Branislav (referee) ; Škrabánek, Pavel (advisor)
The bachelor's thesis is devoted to the creation of a digital twin of the transport line called Interoll, which will reflect the dimensions of the real model, information about the functionality of the drives and information about the correct functioning of the control logic of the whole system. The next section describes Industry 4.0 and the use of digital twins. Furthermore, the thesis deals with the design of a 3D model of a transport line, the creation of logic control and digital twin drives using software from the Siemens company. The output of the thesis is a properly functioning digital twin of the Interoll transport line.
Asset Administration Shell for PLC
Maslowski, Jakub ; Arm, Jakub (referee) ; Benešl, Tomáš (advisor)
This bachelor work gradually summarizes the findings regarding I4.0, as well as its basic parts (AAS, RAMI and DT). Subsequently, it focuses on the description of AAS with regard to the necessary compromises from its original idea with the aim of its successful implementation in PLC, which represents some limitations. The work includes solutions of suitable communication protocols for AAS in PLC. The practical part focuses on the implementation of AAS in PLC from Siemens S7-1200 series using OPC UA methods. SiOME and UaExpert programs are used in the creation. The thesis contains detailed instructions for replication of AAS implementation together with suggestions for possible improvements and its benefits in practise.
Lab Automation with SCARA Robot
Machala, Jan ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The aim of this thesis is to design and program a robotic cell for processing Covid-19 laboratory samples. To prevent the leakage of hazardous substances into the environment, the entire robotic cell is restricted to the space of a laminar box. The Epson LS3-B SCARA robot was chosen for handling the tubes. The robotic cell was designed using a digital twin in the simulation environment of Epson RC+ software. The digital twin facilitated the prototyping of the robot end effector and helped to detect any collisions that may have occurred in the confined space. After successful design using the digital twin, this robot cell was assembled and tested in a real-world environment.
Modelling of the Gear Pump Manufacturing
Horák, Michal ; Rožňák, Ing Martin (referee) ; Videcká, Zdeňka (advisor)
The diploma thesis deals with the analysis and optimization of production lines of the gear pump components. Specifically, it is pre-production, ie a production line for machining gears and production line for machining of bodies. These two components are then assembled on the assembly line. The creation of a simulation model in the Tecnomatix Plant Simulation program, which corresponds to the real state of production lines, is used for optimization. The simulation model is then used to perform the proposed experiments in order to optimize production lines and select the ideal solution with respect to the selected objectives.
