Design of a chess manipulator
Novák, Tomáš ; Parák, Roman (referee) ; Cejpek, Zdeněk (advisor)
The bachelor’s thesis deals with a design and realization of a chess manipulator and its controlling through a graphical user-friendly interface. The theoretical part is divided into two sections, a brief insight into manipulation technique and a more in-depth characteristic of robotic manipulators. The practical part focuses on the chosen chess set and a concept of the robotic manipulator. The following parts then describe the structural units, motor and control units and electronic components. Additionally involves the practical part the design and implementation of the manipulator via the Arduino and the user interface. In the final part is created a functional model and designed possible future improvements and development.

Adjustment of scene for electronic devices detection
Hynčica, Tomáš ; Honec, Peter (referee) ; Janáková, Ilona (advisor)
This work describes development of control hardware and software for automatic production of tuning fork with tip for atomic force microscopy (AFM). A specialized device implementing the problem is developed and tested. The advantage of the proposed solution is the ability to produce the tuning forks with constant parameters, which is an important condition for successful work with the microscope.

PiezoLegs motor in medical aplication
Plass, Petr ; Koláčný, Josef (referee) ; Ondrák, Tomáš (advisor)
The Bachelor’s thesis is focused to explain of basic conceptions of piezoelectric motors including principles of piezoelectric effect. It is analysed velocities of movement of PiezoWave motor during loading and he is valued supply voltage of used demo driver. Then it is considered of drive with stepper motor and DC motor, it is compared them with piezoelectric motor and chosen the best alternate for the drive of a pump of the artificial heart. Then it is introduced with working in a program i-Speed 2 to analyzing of shots catch by the high speed video camera and it is given a basic manual to connecting, setting and programming of the drive connected to the EPOS P driving unit.

Design of a semi-automatic positioning system for measuring of semiconductor chips
Kotian, Tomáš ; Vyroubal, Petr (referee) ; Otáhal, Alexandr (advisor)
The aim of this bachelor thesis is to design and create a system for a semi-automatic positioning system for the test of semiconductor chips. The work solves the problem with the implementation design to achieve the highest possible accuracy for contacting with the help of a probe card. Furthermore, the work deals with the selection of a suitable control unit for stepper motors and finally to create a program for focusing and centering the chip using the image from the camera.

Manipulator Control for Acquisition of the Eye Retina
Malaník, Petr ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
To use the image of the retina for biometric or medical purposes, it is necessary that the image is of the highest quality and ideally covers the largest possible area. It is therefore necessary to move the sensing device to the most suitable position while ensuring its stability. A laboratory handling platform is used for this purpose. The platform is moved by stepper motors. A control board equipped with a microcontroller has been developed for their control, which allows very fine movements. The theoretical accuracy of the manipulator is up to 20 nm. Since it is necessary for sensing, to have proper retina illumination, the control system also includes adjustable illumination elements in the infrared and visible spectrum. The resulting system allows scanning of the retina of the eye from multiple angles and thereby effectively increase the area on which it is possible to further look for diseases or biometric features.

Design and implementation of control program for CNC machine via B&R Automation
Vavrík, Michal ; Lang, Stanislav (referee) ; Parák, Roman (advisor)
The aim of the diploma thesis is the robotization of a conventional milling machine to a CNC milling machine using a programmable logic controller. The theoretical part of the thesis contains a description of machine tools and industry 4.0, an overview of Optimum Maschinen and B&R Automation companies, including products, and a description of the G code programming language. At the beginning of the practical part, the selected hardware, its connection and tuning of motors are described. Furthermore, the practical part explains the method of motor control and processing of CNC programs in G code. The following chapters discuss the creation of industrial visualizations for machine control and digital twin for testing purposes. The conclusion describes the evaluation of the results and indicates the possibilities for future expansion of the machine and its implementation in an automated cell in the sense of industry 4.0.

The modernization of CNC system of milling machine EMCO
Kučera, Vítězslav ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
This master´s thesis deals with the modernization of the EMCO milling machine control system. The theoretical part is focused on the basic description of CNC machine and current state of EMCO milling machine control system. The main point of this thesis is new control system design for given milling machine, when the proposed variants are described and compared according to construction and price. The one variant is selected that best suits the specified parameters. Also, in the TwinCAT development interface from Beckhoff the new control system is created and described in the end of this work.
