Design of Sensor Modules for ZigBee Wireless Network
Tichý, Andrej ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The purpose of this study is to contribute to spreading of the global phenomenon IoT and to create a sensory network. In my study I focused on the development of active and passive modules using the IEEE802.15.4 standard based on the ZigBee protocol. When creating my modules I was using the micro-controller CC2530 by Texas Instruments having the processor platform 8051. To implement the communication firmware for sensory modules I used the Z-Stack 3.0 implementation. The main communicator uses the CC2530 micro-controller as ZigBee network preprocessor and miniPC raspberry pi as ZigBee application processor. As a part of this study I created an active module that enables to control the relay; an RGB led strap using the PWM modulation and also the electric current measurement using noninvasive sensors. I also created a passive module including sensors BME280, TSL2561 and DHT11 to measure the air pressure, temperature, humidity and light intensity. Furthermore I created an universal module that makes easier the creation of new prototypes. Not least I created all-purpose raspberry mini-module. The relevance of this study is given by creation of module prototypes using the ZigBee protocol. Special value within this study has the the mini-module for Raspberry Pi which can be used in various roles within the ZigBee topology.

Automated Creation of Portable Stimuli Scenarios Using Evolutionary Algorithms
Tichý, Andrej ; Bardonek, Petr (referee) ; Zachariášová, Marcela (advisor)
This thesis focuses on the automation of scenarios creation for Portable Stimulus standard. The main goal of the work is an automatic generation of tests, which are defined as graphs for the Questa inFact tool from the Mentor company. For the automation I used an evolutionary algorithm with using a grammatical evolution. The generated scenarios are connected to the existing verification environment based on UVM methodology, then the verification of the connected component is started. Based on the achieved functional and structural coverage, the individual's fitness value is calculated and propagated into an evolutionary algorithm. At the end of the work, experiments are performed on the timer component and the contribution of the proposed evolutionary algorithm is evaluated. The proposed evolutionary algorithm is configurable by grammar and user-defined basic transactions, which allows a wide range of uses. The evolutionary algorithm managed to achieve high functional and structural coverage on the verified timer component.

Web Portal for Ground Robot Management
Tichý, Andrej ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
This work deals with the creation of a web portal for administration and management of ground robots at the Faculty of Information Technology in Brno. The main aim of this work is the design and implementation of the application, which, thanks to robotic platform Robot Operating System administers and manages land robots. Maps are stored in SVG format and spracúváva their library Raphael.js. When the work was created node in Python to control the robot in the Robot Operating System. In conclusion I graded the test user satisfaction with a graphical user interface and summarized the pros and cons of the application.
