Gamma Radiation Measurement
Lázna, Tomáš ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
This thesis is focused on detection of ionizing radiation, especially gamma radiation. In its theoretical part the issue is presented and the most common detector types (gas filled, scintillation and semiconductor detectors) are analysed. In its practical part the parameters of the chosen sensor HDS-100GN are verified with a focus on its capability of dynamical measurement. The robot Orpheus-X3 equipped with the precise RTK-GNSS receiver was used in the realization of the experiment. The analysis of the measurement results furthermore covers conversion of geographical coordinates to distance, determination of latency, conversion of measured value to dose rate and comparison with theoretical assumptions were solved. Formation of an area radiation map is also concerned. Direction-sensitive detection of gamma radiation is also studied in this thesis.

CAN sniffer
Skalický, Jakub ; Jílek, Tomáš (referee) ; Burian, František (advisor)
This bachelor thesis deals with creating CAN Bus sniffer witch sending data to PC by Ethernet. The main parts of developed PCB are microcontroller SMT32F407VGT6 by STMicroelectronics and Ethernet PHY KSZ8051MLL. In theoretical part you can find ARM and STM32F407VGTE information followed by Ethernet and UDP protocol introduction. The end of theoretical part is about CAN bus. Practical part is about design of board, developing it and measuring parameters of board. The end part of this thesis describes changes of software. Firstly there are described changes of firmware for add support of CanShark board. Followed is described adding of new functionality of canshark-gui PC application.

Processing of localization data and its accuracy
Návara, Marek ; Baránek, Radek (referee) ; Jílek, Tomáš (advisor)
This work is focused on correction of localization data, relative to them location of the sensor on robot. Also solves the conversion between coordinate systems WGS-84, ETRS-89 and local coordinate system. For localization data are designed error characteristics and their transformation.These points have been implemented in C#. Classes were firstly developer for single-axis sensors and they are base for multi-axis sensors. The implementation has been tested on simulated data and verified in the experiment with the robot envMap. Experiment results show that the correction is implemented properly and can be further used. Error characteristics listed in the work characterize the measurement uncertainty of location data and can be used in further processing.

Control of a robotic lawn mower
Škapa, Antonín ; Gábrlík, Petr (referee) ; Jílek, Tomáš (advisor)
This master‘s thesis deals with development and realisation of robotic lawn mower with satelite navigation. It begins with preparation of a platform for outdoor mobile robot navigation and it’s control HW and SW. There are discussed different options of navigation both commercial and experimental. Further on I have chosen the right GNSS receiver based on market research and user experience. The GNSS receiver’s parameters are measured with different antennas. Following with the choice of suitable open-source control unit and it’s software implementation. Furthermore control from a companion computer is described and physical realisation is done. In the end of the thesis activation of the whole mower is performed and described. Lastly there are discussed possible ways of future development.

Evolutionary Design of Artificial Neural Network
Jílek, Tomáš ; Šperka, Svatopluk (referee) ; Pospíchal, Petr (advisor)
Focus of this bachelor thesis is on Neural networks, Genetic algorithms and Evolutionary Design. First part of thesis describes Neural networks, their history, training and ways of use and Genetic algorithms, their components, operators and practical application. Next part is devoted to prediction of time series, specifically prediction with use of Neural networks. This is followed by practical part of work, implementation of experiments with Evolutionary design of Neural networks for prediction in which currency exchange rates of several countries are used as a predicted time series. Results and discussion about further development of thesis are described in last chapter.

Remote control of remote communication board of mobile robot
Jílek, Tomáš ; Žalud, Luděk (referee) ; Burian, František (advisor)
The thesis discusses the possible ways of remote management of devices running Mikrotik RouterOS and choosing appropriate variant for implementation of automated remote management of the device, which is part of a mobile robot. Due to the limited capabilities of embedded system, from which it is necessary to perform automated remote management of device with this operating system, it was not possible to use standardized protocols for this purpose. A substantial part of this work therefore deals with analysis and detailed documentation of proprietary protocols implemented in the MikroTik RouterOS operating system, which are suitable for implementation in an embedded system, from which it is necessary to perform automated remote management. The conclusion describes the principle of the proposed and realized implementation of proprietary protocols in C language. The described implementation is part of the library, which provides automated remote management using these protocols.

GNSS Navigated Mobile Robot
Chmelař, Jakub ; Jílek, Tomáš (referee) ; Kopečný, Lukáš (advisor)
The diploma thesis is focused on the topic of global satellite navigation of mobile robots. The paper describes the principle of currently available global satellite navigation systems. The main element of the thesis is the proposal of mobile robot navigation algorithm. An integral part is also the design of a mobile robot to verify the functionality of the navigation algorithm. The robot software program is described. At the end, everything is verified by real experiments.

Heat exchanger design
Jílek, Tomáš ; Kudela, Libor (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with the design of a tube heat exchanger for water - water media, which is part of a cooling circuit. The thesis contains basic description and distribution of tube heat exchangers. It also includes designing and calculating geometric dimensions, calculating the pressure losses in the pipe and intermediate flange spaces and calculating the actual output of the heat exchanger. Part of the thesis is also drawing documentation of the proposed heat exchanger.
