Machine vision for product inspection
Strach, Petr ; Bražina, Jakub (referee) ; Vetiška, Jan (advisor)
The diploma thesis deals with machine vision in connection with robotic production systems. The theoretical part deals with machine vision hardware, principles and characteristics of machine vision, typical tasks in connection with machine vision, robot guidance using a camera, logical tasks for image processing in the TwinCAT program. The practical part focuses on the design of a robotic workplace with a camera to control the rotation of the part. This workplace was first put into operation virtually and then tested at a real workplace.

Design of the robotic work cell for the spot welding
Hrubeš, Kryštof ; Szabari, Mikuláš (referee) ; Bražina, Jakub (advisor)
This work deals with the design and creation of a virtual simulation of a robotic workplace for spot welding in the Tecnomatix Process Simulate. The aim of the work is to get acquainted with the issues of robotic workplaces, especially in the field of spot. Then, based on this knowledge, design a robotic work cell for welding two sheets. The whole process will then be simulated in the Tecnomatix Process Simulate and this simulation will serve as a demonstration in teaching.

Using artificial intelligence to monitor the state of the machine
Popara, Nikola ; Bražina, Jakub (referee) ; Kovář, Jiří (advisor)
This thesis is focus on monitoring state of machine parts that are under the most stress. Type of artificial intelligence used in this work is recurrent neural network and its modifications. Chosen type of neural network was used because of the sequential character of used data. This thesis is solving three problems. In first problem algorithm is trying to determine state of mill tool wear using recurrent neural network. Used method for monitoring state is indirect. Second Problem was focused on detecting fault of a bearing and classifying it to specific category. In third problem RNN is used to predict RUL of monitored bearing.

Virtual commissioning of the robotic production cell
Baťka, Tomáš ; Vetiška, Jan (referee) ; Bražina, Jakub (advisor)
The diploma thesis deals with the virtual commissioning of robotic workplace designed to engrave board materials and their subsequent packaging. The summary of the knowledge that contributes to the development of the virtual commissioning as well as description of each component of the given robotic cell, are described in the theoretical part. In the practical part are described procedures such as assembling of the simulation model in Process Simulate software, creating the PLC program in integrated development environment TIA Portal or creating visualization for HMI panel. In the end, the actual commissioning of the workplace was performed, followed by additional modification and validation of the robotic program.

Virtual commissioning of robotic production system
Sláma, Martin ; Vetiška, Jan (referee) ; Bražina, Jakub (advisor)
The diploma thesis deals with the virtual commissioning of a robotic production system, which is located at the workshop of the Institute of Production Machines, Systems and Robotics BUT. The theoretical part of the thesis contains an overview of the current state of knowledge in the field of virtual commissioning and a description of the elements to achieve it. Next, the devices located in the specified robotic production cell are described. The practical part then describes the process of creating a simulation model in the program RobotStudio and its subsequent connection with the controlling PLC in TIA Portal via SIMIT and thus perform a virtual commissioning of the workplace.

Digital commissioning of a robotic production system for resistance welding
Šuba, Marek ; Bražina, Jakub (referee) ; Vetiška, Jan (advisor)
The subject of this diploma thesis is the simulation and digital commissioning of a robotic production system for welding elements such as studs on sheet metal parts. The basis of the work is search of information related to industrial robots, PLC control, tools used for welding, fixtures, manipulators, sensors, safety and protection elements commonly used in such production systems. The second part of the work deals with the given problem and it is a virtual commissioning of the given concept of a robotic production system. This means creating its simulation model in the Process Simulate environment, selecting robots, creating robotic trajectories, collision analysis, creating sensors, signals and optimization. Last part includes the connection of the simulation model with the software S-7PLCSIM Advanced and TIA Portal, the creation of control PLC logic in the form of a program, visualization and verification of their functionality using the above-mentioned connection with the simulation model.

Design of signal generator for acoustic actuator
Demura, Dominik ; Bražina, Jakub (referee) ; Pruša, Radomír (advisor)
The topic of this bachelor thesis is the design and execution of a signal generator with different signal shapes. The signals will be reproduced by of an acoustic actuator. The generator is able to generate an acoustic output signal with variable parameters such as frequency and phase shift. The whole system was implemented using the Arduino platform and programmed using the Wiring programming language. The AD9833 generator was used to generate the signals.
