Remote controlled wheel robot
Ruhás, Sándor ; Kříž, Vlastimil (referee) ; Florián, Tomáš (advisor)
Tato práce se zabývá návrhem a vytvořením kolového robotu na dálkové ovládání. První část práce obsahuje základní úvod do robotiky. Poté se čtenář seznámí se všemi kroky návrhu, které byly provedeny. Samotná konstrukce je rozdělena do dvou hlavních částí: návrh hardware a software. V kapitole návrhu hardware se čtenář dozví, jaké součástky byly vybrány a proč. Pro vysvětlení funkce součástek, budou uvedeny některé důležité parametry. Protože většina součástek může být nastavena různým způsobem, jsou hlavní nastavení detailně popsána. V dokumentu je také uveden jednoduchý ilustrovaný popis hlavních funkcí obslužného software. Na konci tohoto textu jsou diskutovány dosažené výsledky.

ZigBee implementation for Automotive Industry
Zatloukal, Martin ; Maršálek, Roman (referee) ; Prokopec, Jan (advisor)
This bachelor’s thesis describes possibilities of usage of ZigBee communication protocol in automotive industry, transport and logistics. Thesis also deals with ways of practical implementation of ZigBee protocol including typical cases solutions, designing and realization of necessary electrotechnical devices and modules followed by compilation of control software and experimental measurements of these devices in real traffic flow. In the first part of thesis, there are some basic features and parameters of ZigBee reminded, followed by ways of ZigBee communicator usage description and adumbrating how to perform integration with existing practical systems. The second part is about analysis of ZigBee data system construction, communication system scheme design and pre-projection of block schemes of its particular cells. The third part concretizes requested functions and features of these cells and describes ways of its hardware realization. The fourth section describes controlling software design, connection and controll of functions using PC and additional programs, using of X-CTU software offered by MaxStream Company to set up XBee parameters and using of AVR Studio 4 offered by Atmel Company to set up ATmega16 processor. The last part is taken by completation of hardware and software, tests with a few of XBee chips and network nodes in laboratory conditions and examples from the real traffic range measurement.

Low-power wireless sensor node
Pobiecky, Michal ; Koton, Jaroslav (referee) ; Krajsa, Ondřej (advisor)
The main purpose od this thesis is to design wireless sensor node with emphasis on low power consumption. This device is firstly made of microcontroller Atmel ATmega328P and for transferring measured data XBee 802.15.4 or transceiver nRF24L01 is used. Subsequently there is a design with Atmel ATmega256RFR2 with integrated wireless part and Lightweight Mesh protocol. Special attention is given to sleep modes and lowering power consumption. For ATmega328P the measurement of these power modes is done.

Measuring and Visualizing Distance Sensor Data in Real-Time via Arduino and Xbee wireless communication to Matlab
Zapletal, Marek ; Liška, Radovan (referee) ; Karakhalil, Mourad (advisor)
Work describes making of measuring system consisting of ultrasonic sensor, programmable board Arduino, where the wireless communication is provided by Xbee modules. Theoretical part depicts the single components including the programmes for making the code necessary for proper function of the system. On the other hand, realization and creation of programmes is the centre of practical part of the work. System was physically made and the obtained data from distance sensor were in real-time transferred and depicted in MATLAB programme, where the data are filtered and the graphs of elapsed time- distance are drawn. This work is one of the first possible steps in making intelligent devices or robots from the general aspect of mapping, navigating and orienting in a surrounding area.

Wireless Sensor Network with Arduino Components
Šplíchal, Jakub ; Zbořil, František (referee) ; Samek, Jan (advisor)
This thesis deals with the creation of wireless sensor networks consisting of components Arduino. The work includes introduction to the Arduino platform and its capabilities in combination with the wireless XBee modules. The important part is design a wireless network from these components and applications for the display of measured values from sensor nodes. The goal is to create sensor network with a dynamic topology and examine its behavior in real environment and the creation of applications for saving and displaying measured data from individual sensor nodes.

Intelligent house for elderly people
Piši, Daniel ; Hynčica, Ondřej (referee) ; Mehrdadi, Bruce (referee) ; Kučera, Pavel (advisor)
Tato diplomová práce se zabývá systémem automatizace domácnosti umožňujícím ovládání domácích spotřebičů prostřednictvím běžné televize. Systém využívá standardu X10 a bezdrátové technologie ZigBee. Řídicí software staví na OS GNU/Linux a systému domácího kina MythTV. V rámci této diplomové práce byla vyvinuta aplikace zprostředkující komunikaci mezi MythTV a hardwarem. Modulární koncept postavený na dynamicky zaváděných modulech dělá tuto aplikaci snadno rozšiřitelnou a použitelnou i mimo předkládaný automatizační systém. Za účelem testování a demonstrace funkčnosti byl dále navržen bezdrátový teploměr a převodník VGA na SCART.

Modem for powerline communication
Sláčik, Ján ; Mlýnek, Petr (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis is dealing with the standards and usable circuits applications for a powerline communication, which are currently available. Principle of this kind of communication is described for default supply network 230 V/50 Hz. This work is also describing several available modems which can be used for this type of communication. The properties of the standards PRIME and the G3-PLC, which are presently at disposal, are specified, measured and compared with each other in this project. The concentrator based on the G3-PLC standard extended about radio interface was designed. Afterwards this device was tested in various topologies and interference scenarios. The graphical interfaces, which allow the transfer measurements in multiple modes are described is this work as well. The entire measurements were realized in a real conditions for both tested modems. The results of these measurements are validating the purpose of each standard and its configuration.
