Development of a linear stage actuator for UHV STM/AFM
Pavelec, Jiří ; Jiruše, Jaroslav (referee) ; Šikola, Tomáš (advisor)
The aim of this diploma thesis is to develop a linear positioning stage for Ultra High Vacuum (UHV) environment. Simple prototypes of the linear positioning stage were designed and incorporated as part of a multiaxis sample manipulator for a UHV Scanning Tunneling Microscopy / Atomic Force Microscopy (STM/AFM). Different types of position encoders and linear guideways are discussed. Implementation of the homodyne interferometer as an optimization tool for a slip-stick based linear stage is described. Scalar diffraction theory is used to model the diffraction grating optical position encoder behavior.

Design of camera crane
Navrátil, Pavel ; Hutař, Pavel (referee) ; Koutný, Daniel (advisor)
This Master’s thesis deals with several variants construction design of camera crane. Two optimal variants are chosen with regard to practical usage. The thesis includes complete design of these variants with 3D models and strenght analyses. This analyses are processed by final element method. The first variant made based on technical documentation and it has worked for company Filmochod s.r.o..

Design of manipulator for palletization
Florián, Michal ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
The matter of this master´s thesis is the construction of two variations of manipulator for palletization. The first solution is the derrick manipulator; the second one is the gantry manipulator. The aim of this master´s thesis is the comparison of both solutions from the point of view of the applicability, the cost and the demandingness of production. The productinon documentation will be elaborated for the selected solution.

Modular concept of roller conveyor system
Novotný, Lukáš ; Nosterský, František (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis is dealing with the modular project of a roller conveyer track for transport of europallets with the loading limit of 1200 kg and its use in practise. There are also mentioned possible construction solutions and the actual construction project. It is followed by calculating and modular project of direkt conveyer. Further on, I am dealing with the project of a sliding turntable of cable loops and surfaře covering. In the conclusion, I think out the problems of sensors and a possible operating conveyer.

Electronics for Sewing Machine
Karásek, Josef ; Fedra, Zbyněk (referee) ; Vychodil, Josef (advisor)
The main components of the system for embroidery sewing machine is (Veritas 8014/35-2) and pointing devices. The machine automatically entered embroidered patterns, it is necessary to construct a pointing device and its control. To drive the pointing device used two stepper motors, the control circuit to cater to the ATmega128. Communication between PC and ATmega128 provides converter FT232.

Small CNC machine
Moštěk, Jiří ; Matěj, Zdeněk (referee) ; Záplata, Filip (advisor)
This diploma thesis deals with the design and construction of a three-axis CNC machine primarily designed for PCB drilling and production of front panels for various electronic devices. All three axes are driven by stepper motors NEMA 23 which are connected to stepper motor drivers L6470. Processor STM32F407 is used to control the whole machine. The wiring is completed by a LCD display with touchscreen which is used to communicate with user. Data for drilling can be entering manually or via USB inerface. Part of this thesis is the selection of a suitable construction and components, assembling equipment, wiring design of electronic circuits and writing the code to control the machine. Finally, the parameters of the designed device have been measured.

Literature Review on Track Systems in Field of Machine-Tools
Šváček, Karel ; Michalíček, Michal (referee) ; Holub, Michal (advisor)
The main theme of this thesis is is a description of machine tools slide ways. More and more emphasis is laid on the accuracy of slide ways, because it is among the main parts that influences the exactness of of the mashine and thus the whole making process ass well. Materials that the sliding ways are made of are described here as well as their classification and their use with the CNC machines. The final summary of the thesis contents the evaluation.
