Virtual commissioning of automatic investment casting shell removal
Vach, Pavol ; Bražina, Jakub (referee) ; Szabari, Mikuláš (advisor)
The aim of the diploma thesis is to design and virtually commission a robotic workplace for the automatic removal of shells from castings for investment casting technology. The theoretical part summarizes an overview of programming of industrial robots, PLCs and software for virtual commissioning. Subsequently, the investment casting technology is described. In the analysis of problematics, there is a description of assigned components and analysis of methods for removing shells from castings with a focus on the automation of this process. This is followed by the design of the workplace layout, the virtual commissioning of its model, the design of the control and user interface.

Head-Mounted Display or Tablet? Device Usability in the Context of Programming Robotic Workplaces
Kníže, Josef ; Milet, Tomáš (referee) ; Bambušek, Daniel (advisor)
This thesis focuses on usability comparison of head-mounted display Microsoft HoloLens 2 and tablet in context of programming robotic workplace using augmented reality. The existing interfaces for these devices are analyzed, and a user experiment was designed and conducted to compare them, involving a total of 18 participants who tested and evaluated both devices in two iterations. Based on feedback from the first iteration, many changes were proposed and implemented in the HoloLens 2 interface. Key changes included porting the entire application to newest framework for mixed reality, programming through scene interaction, reworking robot placements, and adding parameter configuration and action placement through the robot. The new version of the interface was tested in the second iteration of experiments, revealing that users are 32,3 % faster when using HoloLens 2 and they rate usability and user experience better compared to tablet. Surprisingly, there was no significant difference measured in user mental or physical load between the devices.

Virtual commissioning of robotic loading of workpieces into the machine tool
Grünwaldová, Kristýna ; Knoflíček, Radek (referee) ; Vetiška, Jan (advisor)
This thesis deals with virtual commissioning of the manipulation station using a robot, while it is a replacement of a workplace that was originally operated by employees. The aim is to make production more efficient by means of robotic loading of workpieces into the machine tool. The thesis describes a sequence of stages that lead to the virtual commissioning of the robotized workpiece placement in the RobotStudio program so that the workplace can be automated. First, it was necessary to design a new concept for the original workplace, then to create this concept in the RobotStudio program, and then to operate the individual elements of the entire workplace and to create a sequence of actions connected to each other as it would be during real operation. In the thesis the connection with the real workplace was not considered, the workplace was put into operation only virtually.

Virtual commissioning of a robotic learning production system
Baránek, Martin ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
Diploma thesis deals with the virtual commissioning of a educational robotic workplace. The theoretical part of the thesis deals with the research of the current state of knowledge of the use of robots in industry, methods of their programming, possibilities of controlling robotic workplaces and methods of procedures for virtual commissioning of robotic workplaces. The practical part of the thesis is devoted to the virtual commissioning of the workplace in Tecnomatix Process Simulate, specifically the processing of the workplace model for simulation and creation of robotic programs, and the creation of PLC control and HMI in the TwinCAT 3 environment.

Spatial Augmented Reality for Robotic Workplace
Štrof, Jakub ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
The focus of this work is to create projected user interface, which will complement AREditor, an application for robotic programming and also to calibrate Kinect and projector using existing calibration method. For calibration, I used the procam-calibration method, which uses projected Gray codes onto a chessboard to calculate calibration parameters. Thanks to it, virtual objects can be placed correctly into the real space. User interface was implemented using game engine Unity. By testing the interface, it was found that it helps the user to better grasp the relation between real and virtual space when placing virtual objects into the robotic workplace. It also raises user's awareness of the robot's movements when cooperating with it.

Virtual commissioning of a robotic learning system
Dejmek, Tomáš ; Knoflíček, Radek (referee) ; Vetiška, Jan (advisor)
This bachelor thesis deals with the virtual commissioning of a robotic system. This system is located in the premises of the Institute of Production Machines, Systems and Robotics of Brno University of Technology. Virtual commissioning has become an indispensable component in the creation of automated workplaces in recent years. It has an impact on reducing costs and downtime in production. The thesis contains a theoretical part, which is devoted to the research of topics related to virtual commissioning. This is put into a broader context with the concept of Industry 4.0. This is followed by a description of the parts of the robotic system and a description of the operations to be performed by the system. The practical part is devoted to a description of the creation of a simulation model in the RobotStudio software. This is followed by the last part, which introduces the creation of educational materials. These materials are text files containing a detailed procedure for working with RobotStudio. The output of this work is the virtual commissioning and creation of the tutorial materials.

Robotic Workplace Programming Using the HoloLens Headset
Kolařík, Petr ; Milet, Tomáš (referee) ; Bambušek, Daniel (advisor)
The bachelor thesis deals with the use of Microsoft Hololens 2 glasses in a robotic workplace. It follows the diploma thesis of ing. Simona Hiadlovská and the existing AREditor user interface connected to ARServer. The first goal of the work was to improve the way of adding objects at a greater distance. Three methods are proposed and compared for this problem: the first is adding at a fixed distance of one meter in the direction of the hand, the second is adding on a perpendicular line drawn from the point of contact between the pointer and the table and then adjusting the height by pulling the hand, and the last is adding also on a perpendicular line but adjusting the height by tapping. The second objective of the work was to devise a method of selecting one object from a cluster of objects. In this case, the methods of simple selection using the pointer, expanding objects from the surroundings and displaying an interactive list of objects are compared.

Development of a universal cell for optical part inspection in a robotic workplace
Cahlík, Radim ; Rajchl, Matej (referee) ; Adámek, Roman (advisor)
Cílem této diplomové práce je vývoj univerzální buňky pro optickou kontrolu včetně softwaru pro detekci vad, který používá metody umělé inteligence. Dalším cílem je integrovat buňku do robotického pracoviště a otestovat ji na rozdílných dílech s různými vadami. První část práce popisuje vývoj konceptu optické buňky a její návrh. Poté pojednává o systému pro optickou kontrolu, počínaje popisem objektivu a kamery a konče analýzou kontrolního softwaru, který pro detekci vad využívá konvoluční neuronovou síť. Další část se zabývá vývojem robotického pracoviště včetně návrhu dvojosého robota a komunikace mezi zařízeními. Nakonec je rozebráno testování na dvou rozdílných dílech s cílem ověřit funkčnost.

Automation of stators production
Šula, Martin ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
The diploma thesis deals with the design of a robotic workplace layout for finishing operations on the stator of an electric motor. Three variants of the workplace layout were created, these variants were evaluated, and then the most suitable variant was selected. Suitable subcomponents have been created for this variant, such as the end effector, deburring spindles, rotary stand and milling table. A risk analysis was also created for her to ensure the safety and protection of the operator. The most suitable variant was transferred to the Process Simulate software, where its functionality was verified and the real cell cycle was determined.
