Mobile robot control system
Bugár, Loránt ; Jílek, Tomáš (referee) ; Hynčica, Ondřej (advisor)
Bachelors project is fixated for creating a mobile robot with a real time operating system. The robot control system is based on a microcontroller Arduino with ARM Cortex-m3 processor. The practical part is dealing with resolving the client-server communication with the UDP protocol, also with the identification of the engine from measured data’s by the Simulink and subsequently designing the PI regulator from the identificated data’s. In he last part of the work the focus is giving to solving the communication with I2C bus and using sensors like : accelerometer, ultrasonic sensor, infra sensor, light sensor, hall sensor and usage of a robotic arm. An application is created for controlling the robot and for visualisation of sensor readings..

Home Security and Monitoring System
Valach, Lukáš ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The thesis elaborates on an implementation of wireless home security system. The wireless communication utilizes IEEE 802.15.4 radios and ZigBee communication protocol. The beginning of the thesis provides specification of the intended system followed by an evaluation of usable energy harvesting solutions and later by consideration of single board computer systems suitable for implementation of the control node of the sensor network. The rest of the thesis describes design, implementation and testing of particular components of the security system. Conclusion evaluates the achieved goals and offers suggestions for future work. The end products of the thesis are physical devices implementing wireless sensor nodes, control unit of the security system as well as a graphical user interface for the system management.

ARM Remote debugging over industrial bus.
Skalický, Jakub ; Jílek, Tomáš (referee) ; Burian, František (advisor)
This semestral thesis is concerned on facilities of using DebugMonitor exception for debugging software which run on ARM Cortex-M4. The comunnication between debugged software and debugging master is implemented via CAN bus. The result is support for debugging without special debugging equipment. For support of this type of debug this thesis implemented code library called SDebug. It's managing parts of Cortex-M4 core, which are userd for debug.

Control unit for automatic laboratory manipulation system
Vávra, Tomáš ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
This document deals with devices which are used for the automatic Gram staining. The document starts by a research with the aim to discover existing devices and to compare them to the concept of the device developed by company Biovendor. There is theoretically and then practically dealed with the methods of the rotor imbalance detection and measurement of water-level. The Practical part of this document describes the development of the control unit with the microcontroller ARM Cortex-M3 which will be used for the prototype development of Biovendor’s device. The Last part describes measurement of imbalance of three different rotors with the aid of the control unit.

NFC technology and its security
Mertlík, Tomáš ; Babnič, Patrik (referee) ; Rosenberg, Martin (advisor)
The first objective of this paper is to describe the Android operating system. The chapter presents history and architecture regarding to all versions of the operating system. The significant part of chapter is focused on security. The second main topic of this paper is analysing the NFC (Near Field Communication) technology. This technology is based on an older contactless system RFID (Radio Frequency Communication), so RFID is described either. The NFC technology chapter contains the description of usability, history and the definitions of physical layer, link layer and NDEF (NFC Data Exchange) data format, used for data transmitting. The next chapter is focusing on the analysis of the NFC vulnerability. It contains a possible attacks methods and solutions how to prevent them. The output of this paper is the projection and creation of an application, which allow sending an arbitrary data between two devices using the NFC technology. Additional Bluetooth technology can be used for larger files. In this case, NFC helps to create Bluetooth communication channel which is utilized for data transfer.

Mobile robot control system
Kalina, Michal ; Veselý, Libor (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with building of two-wheeled mobile robot and consecutive creation of drivers and control for sensors, engines and controller design. The control is based on Arduino platform using ATmega328 processor. Firstly there is in this thesis recherche. Part of this thesis is modelling one where simulation model of our system is created, its linearization and then controller design. Further it contains description of the building robots body, description and functionallity of used engines, description of all sensors and detailed description of available printed circuit board. In the end there is software part where the engines control is described, operation of the sensors and functionallity of the controller. Result of this thesis is function application of controlling and operating of two-wheeled unstable mobile robot.

Analog system SW simulator
Košta, Ondřej ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This Master’s Thesis focuses on development and realization of analog system software simulator for simulation of various kinds and orders systems and for function verification of microcontrollers’ control systems. The development and realization of PSD controller is part of this thesis as well. The simulator is written in C++/CLI programming language which combines fast execution of native code and provides an advantage of managed code which has its execution managed by the .NET Framework. The data acquisition is performed via National Instrument’s USB multifunctional DAQ. The PSD regulator is realized by using modern ARM processor architecture.

Audio Saving Module
Strašil, Ivo ; Kouřil, Jiří (referee) ; Říha, Kamil (advisor)
The aim of this thesis was to design and construct an autonomous, hardware voice recorder/player module. The device is made as a compact, built-in component for a motherboard of a target appliance. During recording, the incoming analog voice signal is converted to a digital stream by an ADC with 16 bits resolution and 24 kHz sample rate. Microcontroller LPC2103 (ARM7TDMI core) processes data, recalculates resolution and sample rate, encodes and converts to WAV format and save into a FAT/FAT32 filesystem on a Secure Digital memory card. At playback, the process is opposite: the microcontroller reads file from the memory card, decodes the stream and sends it to a DAC and then to a reconstruction filter. So there is an analog voice signal at the output again. The firmware allows control by logic inputs or by a serial bus, processing of uncompressed WAV files or WAV files with A-law or IMA ADPCM compression, continual recording including automatic freeing of card space by deleting the oldest records and a usage of a voice emphasis filter or of a signal dynamic compression circuit.
