Manipulator control via microcontroller
Šíl, Petr ; Liška, Radovan (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to the control of the manipulator by microcontroller. It is a scale model of the manipulator, which will demonstrate the functions of a similar manipulator in the real time practice. The design of the manipulator consists of two parts, the mechanical part and driving part. In each section were chosen suitable parts to fulfil requirements of desired functions. The functionality, simplicity of manufacturing of all sections, the price and simplicity of control were the main criteria during the design of the manipulator. The system utilised ATmega 128 and development environment AVR Studio 4 to control and test microcontroller ATmega128.

Construction of a mobile robot for monitoring ambient temperatures
Ferenčák, Libor ; Jančík, Stanislav (referee) ; Zuth, Daniel (advisor)
The aim of this bachelor´s thesis is to design and to construct a mobile robot that is able to monitor ambient temperature and to watch if there is no danger caused by high temperature. The work also deals with the theoretical description of elements that could be used. The whole system is based on ATmega microcontroller 128, which is described here, including the support plate. The individual components that are used in a robot are also described here, and programs controlling the individual components are attached. An algorithm is designed and described to a detail which could control the robot and monitor the temperature.

Table tennis robot
Nguyen, Thuc Tuyen ; Věchet, Stanislav (referee) ; Marada, Tomáš (advisor)
This diploma thesis deals with designing and manipulating a robot for training table tennis. Robot's mechanical construction is based on aluminium profiles supported by various standardized assembly units, such as rotating bearings, plain bearings, threaded rods... The front-end part of the robot, which requires better deformation property and lighter weight, was made from ABS material using 3D rapid prototyping technology. The design of the robot allows its body to rotate around three axises. Thanks to the high dynamical ability, robot can be set to throw balls to various places on the playing table, with different types of ball spin. Balls will be shot out by two rubber wheels, which are attached to two electrical DC motors. By driving the speed of the two motors, we can control the speed of the ball, as well as speed of its spin. All robot's activities are driven by an embedded system designed using microcontroller ATMega128. A firmware for controlling robot's function was writen and flashed into the microcontroller. End-users might communicate with the robot via a system of buttons and a text LCD display. The built robot was tested and it has shown its ability to throw balls to 6 different places of the playing table, at different speeds, with different types of ball spin, and different spin speed, according to the parameters set by user.

Alternative methods and algorithms for flame detection
Kozubík, Kamil ; Dřínovský, Jiří (referee) ; Frýza, Tomáš (advisor)
This master’s thesis deals with flame detection methods. The purpose of the project was to create a flame detector, which uses the alternative method of flame detection. The introduction of this thesis gives the summary overview of the existing methods for flame detection. Further, the existing flame detectors and their applications are described. Two alternative algorithms for flame detection which are based on the digital signal analysis were realized on the PC. Flame detector, which utilizes the digital analysis of audio signal, was realized on 8 bit microcontroller Atmega128 and achieved results are presented.

Microprocessor control unit with frequency synthesizer for SW radiostation
Povalač, Aleš ; Fuchs, Michal (referee) ; Šebesta, Jiří (advisor)
The thesis is focused on the development of a radioamateur short-wave transceiver. The basic functions, features and parameters are described in the introduction. The bandplan and appropriate types of emission are also included in the introductory part. The frequency synthesis module is discussed in the second part of the document. Emphasis is placed on the direct digital synthesis method (DDS) using modern Analog Devices circuits. The proposed DDS module includes a high-speed clock source. The description of an intermediate frequency module with a demodulator is also placed there. The final part in devoted to the design of a transceiver control panel with a graphical display, a keyboard and a rotary encoder. The firmware for an ATmega128 microcontroller is described in detail at the end of the thesis.

3D dental scanner
Kotek, Lukáš ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
The general aim of my master´s thesis is to study the actual principles of 3D scanning, the anatomy of human teeth, use of 3D scanning in dentistry and other medical fields. Another part of this thesis is about software and hardware design of 3D scanning system, which enable us to scan dental casts. This design is using webcam, projector and turntable. The principle of scanning is based on the activ triangulation. The output of 3D scanner is a horde of spots, which are used for reconstruction of a surface. The reconstructed surface is finally saved as .stl format.
