Using optimization methods to design machine parts
Kubrický, Daniel ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This bachelor thesis describes using structural optimization methods to design machine parts. In the first part of the thesis, a description of the current state of knowledge of the optimization process was made together with its theoretical background. In the second part of the thesis, a static analysis and topology optimization or Generative design was developed using the example of a bell crank in six commercial software. In the third part, the resulting models of each software were compared with each other, and the results were compared using the von Mises maximum stress criterion and the overall model deformation. Finally, this work was concluded with an evaluation of the use of the structural optimization software.

Topology Optimization of the Hinge on Elastic Foundation
Beruashvili, Vasili ; Symonov, Volodymyr (referee) ; Löffelmann, František (advisor)
Tato diplomová práce se zabývá modifikací původního tvaru součásti za účelem co nejlepšího splnění provozních podmínek daného zatížení a omezujících podmínek v programech M.S.C. NASTRAN, M.S.C. PATRAN a FUSION 360. Součást je připevněna na ortotropní desce (sendvičovém panelu). Cílem této práce je zjištění efektu elastického podkladu na výsledky optimalizace. Součást bude optimalizována za použití různých cílových funkcí a omezení. Elastický podklad změní tuhost, což může změnit napěťový stav součásti. Únosnost původního a modifikovaného tvaru bude srovnána pomocí programu M.S.C NASTRAN/PATRAN. Po tvarové optimalizaci má být 3D model připravený pro výrobní proces, který bude cenově nejefektivnější.

Virtual commissioning of the machining workplace
Valach, Tomáš ; Štěpánek, Vojtěch (referee) ; Bražina, Jakub (advisor)
This diploma thesis deals with virtual commissioning of production system for robotic milling, which is located in the laboratories of the Institute of Production Machines, Systems and Robotics at the BUT. In the theoretical part of this thesis is described the issue of virtual commissioning, uses of robot systems in milling operations and software usable for virtual commissioning. Practical part of the thesis contains description to creating CAM operations, the creation of 3D model of workplace and PLC program and its HMI. Programs Fusion 360, Robot studio 2021, TwinCAT and OPC UA were used for the actual implementation.

Innovative tool for removing bad pronunciation of the letter "R"
Rexová, Natálie ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
The purpose of this final thesis is to find out about Speech Therapy and to design a device which would help with oscillation of human tongue when the sound r is pronounced. To better understand this subject first part of this thesis takes interest in evolution and physiology of human speech. Next the most common articulation disorder Dyslalia is named and methods for treating Dyslalia are described. In practical part the device for Speech Therapy is designed and created. It is based on frequency of human tongue oscillations and it helps to correct difficulties with sound r articulation. This prototype uses electric motor which is controlled by Arduino platform. Its rotational motion is converted to linear through mechanical construction simulating crank mechanism.

Smart garden control system
Antoš, Jan ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This bachelor thesis aims to design and implement a distributed control system concept for a smart garden. This system can measure individual physical variables, process the measured data, send it to a central unit and display it to the user. The measured data is then backed up in a database, which is linked to the web for visualisation.

The multiaxis manipulator
Majnuš, Martin ; Benešl, Tomáš (referee) ; Burian, František (advisor)
The thesis deals with the calculation of kinematics of the multi-axis manipulator type RLRL - SCARA robot, calculation of static forces acting on stepper motors and calculation of theoretical adhesion force required for the end effector. The suction cup diameter is also determined from the magnitude of the holding force. It also deals with the modification of the driver used for the Raspberry pico 2040 microcontroller. It also includes the design of the circuit board for switching the inductive load along with the design and subsequent physical implementation of the manipulator including the pneumatic and electronic parts. The last part of the bachelor thesis briefly describes the program for controlling the manipulator through the terminal.
