Air Hockey - construction design and control design of artificial player
Jašek, Dominik ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
This diploma thesis deals with the design and implementation of an automatic Air hockey player. In particular, a gaming table and a kinematic type of H-bot robot and electronics are designed. The movement of the robot is ensured by two stepper motors, which are controled by the Arduino Micro using timer interrupts. The thesis is improved by additional elements, such as goal detection using photoelectric sensors and automatic firing of the puck from the goal and others. The Air hockey robot was practically realized in cooperation with Ondřej Sláma.

Stepper motor control using CPLD
Daněk, Jan ; Kolouch, Jaromír (referee) ; Kováč, Michal (advisor)
The aim of my bachelor thesis was the control of CPLD stepper motor. To create a radio controlled antenna rotator. The controlling is done by a computer using RF circuits. The thesis includes a construction and principles of stepper motor. Basic structures of CPLD circuits were applying to create the control circuit. The possibilities of sensing the position and the data storage circuit were discussed. The control program in VHDL was implemented in development boards. The development board is connected to radio receiver circuit and the stepper motor driver. A transmitting board was connected to a personal computer or other device using RS232 interface. Printed circuit boards for transmitter and receiver circuits were created. The PC program was designed for data transmission. The program sends data and communicates via RS232 interface.

Program for inovation of the SORT control system
Šulc, Martin ; Kváš, Marek (referee) ; Zezulka, František (advisor)
The analysis for the extension of the control system and proposal of controlling program for surveillance cameras and related theoretical analysis necessary for understanding problems. Proposal communication protocol to access all functions via TCP/IP communication. Subsequent protocol implementation into control program and a programmable controller. Programming application with a user interface for camera control and basic image processing. The program also represents the server for TCP/IP communication with clients over the proposed protocol. The proposed application has to fulfill high pretensions of data streaming from cameras. Extension of the existing control system of the telescope, dome and other systems. The addition of analog measurement and control of digital inputs and outputs. Furthermore, control of stepper motors to control focusers. The embedded communication protocol will be expanded of the new instruction.

Camera slider control
Rajnoch, David ; Götthans, Tomáš (referee) ; Mego, Roman (advisor)
This bachelor thesis describes design and implementation of stepper motor digital controller that manages camera slide movement. The main elements are microcontroller ATmega16 and stepper motor driver TOSHIBA TB6560. Controller allows a time-lapse mode and continuous linear movement including smooth start and stop. Human interaction is based on joystick input and text display connected via HD44780 interface. The theoretical part describes stepper motors and their control modes. The practical part deals with design of electronic circuit and test of functionality.

Control system for remote laser-induced breakdown spectroscopy
Petrilak, Michal ; Fuchs, Michal (referee) ; Kubíček, Michal (advisor)
The work deals with the design of the control electronics for measuring set-up for elemental composition analysis using remote LIBS techniques. The electronics is designed in modular way for light interchangeability and variability. It consists of several separate plug-ins; each plug-in solves its part of the problem and communicates with others over the I2C bus. The work describes the basic components and concepts; a special care is taken to describe the modules for stepper motors control and for communication with focusing lens from Canon company.

Development of the testing device for length measurement
Kirchner, Jan ; Vetiška, Jan (referee) ; Andrš, Ondřej (advisor)
Aim of this thesis is a verification of possibility to measure displacement in small range using sensor based on the principle of strain gauge. For testing purspose, an evaluating unit was designed, made and assembled. This unit contains analog/digital converter, LCD and it has an abbility to move measuring plane using stepper motor. Next part of this thesis is about testing new prototype of strain gauge sensor, including evaluation of results of measuring. The performed measurements were measuring linearity, time stability and repeatability. Based on the results of the measurements, the possibility of using this type of length measuring device was confirmed for further development.

Small Cnc Cutting Machine
Golej, Juraj
This paper deals with design and realization of a large format 2D CNC machine for cutting thin soft materials, especially the cardboard. It includes design, build and revive individual parts of mechanic construction, control electronics and main control program, which processes the input data from external medium (PC or SD card). Important properties are large working area and high speed of movement.
