Educational Tutorial for Using of Arduino in Robotics
Beran, Jan ; Veigend, Petr (referee) ; Rozman, Jaroslav (advisor)
The aim of this thesis is to create an educational tutorial for using Arduino in robotics with the Trilobot robot. The tutorial aims to be focused on the target group of elementary school students and above with an interest in robotics and MCUs, but without any advanced knowledge of their operation. The theoretical part will summarize the current tutorials available for the Arduino and similar, together with the design of the reconstruction of the Trilobot robot and the design of the tutorial. In the practical part, both the creation of the robot itself and the preparation of slides in both Czech and English languages and source codes for the tutorial and testing will be implemented.
EEG Measuring And Analyzing System
Blažej, Svätopluk
One of the critical steps in the design of Brain-Computer Interface applications based on electroencephalography is to process and analyze signals in real-time, in order to identify the mental state of the user. Understanding of signal processing is vital for those who deal with these signals for detection, diagnosis, and treatment of brain disorders and the related diseases. The main asset of this project is to create small, reliable and inexpensive system for analysis of brain activity. This paper describes use of microcontrollers for brain waves readings. Electrodes used for this purpose have sensitive and low noise readings.
End-to-end encryption protocol for IEEE 802.15.4
Bača, Jaromír ; Člupek, Vlastimil (referee) ; Krajsa, Ondřej (advisor)
Tato práce se zabývá problematikou šifrování komunikace mezi nízkonapěťovými zaří-zeními, které jsou ovládány pomocí mikrokontrolerů. V rámci práce byly používány dvěvývojové desky deRFnod, které byly osazeny čipy AVR ATmega 128 RFA1, které umož-ňují bezdrátovou komunikaci. Na těchto zařízeních probíhal vývoj a testování aplikace.Finálním výstupem práce je návrh aplikace pro asymetrickou výměnu klíčů, která jezaložena na eliptických křivkách. Tato aplikace je implantována v Atmel LightWeight,kde je i řešena otázka vzájemné komunikace mezi komunikujícími body. Vygenerovanýklíč je dále použit pro širfování komunikace pomocí šifrovacího algoritmu AES, který jejiž implementován ve využitém LightWeigt protokolu. Toto šifrování umožňuje nejenomšifrování koncových bodů, ale i komunikačního tunelu. Taková ochrana poskytuje uži-vatelům anonymitu dat a znemožňuje nebo velmi znesnadňuje potenciálním útočníkůmzařízení fyzicky lokalizovat na základě znalosti směrování dat v síti.
Internet of Things in Practice
Zajíček, Milan
Prerequisite of working with microcontrollers is understanding the basic principles of their communication with the environment and possible ways of their programming. The ESP8266 microcontroller is one of the most popular chips used in Internet of things applications. Wemos D1 mini is one of development platforms behind the ESP8266,which allows direct communication with the PC via a USB port and has plenty of input and output peripherals to build simple IoT devices. The ArduinoIde development environment is used for programming. The thermostatic switch is made as a result of this tutorial.
Microcontrollers for BLDC Motors
Úlehla, Martin ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
Master thesis deals with solutions of BLDC motors (brushless DC motors) control. It analyses microcontrollers and electronic components suitable for BLDC motor controllers under conditions of serial production. It mentions some common problems in practical aplication like dynamic motor braking, synchronization, recuperation and constant revolutions.
Model of Nonlinear System
Florian, Radim ; Holý, Miroslav (referee) ; Ošmera, Pavel (advisor)
The Thesis provides the project and realization of non-linear system, consisting of direct electric motor and dynamo that are linked together with flexible connector. Firstly, there are decscribed the principles of turns control in direct motor. Secondly, the thesis shows the construction of operating panel with microcontroller PIC16F877. Finally, the last part brings the evaluation of mesurements and suggests various improvements of the operational panel.
Digital filtration in 8-bit microcontrollers
Záplata, Filip ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of my bachelor’s thesis is a digital filtration using the 8-bit processors. Digital filters are in use a lot and gradually outdoing analog equivalents. Their advantages are indisputable, but computing still inhibits bigger progress. Generally used microcontrollers do not have very powerfull core, so there is effort to apply as bright as possible algorithms. Program code can be written in C language or assembler eventually is possible to combine both languages. The task is to make a library of functions based on some powerfull algorithms for filtering. Testing those libraries and comparing their useability focused on maximal speed and universality of use and review ways of programming.
EMD instruments and electromagnetic mmunity
Mikula, Dalibor ; Buchta,, zdeněk (referee) ; Havlíková, Marie (advisor)
The work deals with implantable devices and possibilities of interference of elektromagnetic field. At first, the electromagnetic compatibility is discussed. Basic terms are explained, followed by insisting on resources of possible distrurbing of implantable devices and standards dealing with this issue. Furthermore, short chapter about devices affecting function of implantable devices is introduced. It means devices which patients with implantable devices may meet in common life, as well as devices used in common life, also devices used jn medical environment. In the next part, measuring process of electromamagnetic effect in working compartment of FN Brno magnetotheraphy and elektrotheraphy is devised. There is a concept of measuring card thanks to which impulses of implantable devices are measured. Finally, a description of measuring on implantable devices in FN Brno. MIKULA, D. EMD instruments and electromagnetic immunity. Brno, 2009. 74 s. Master’s thesis in Brno University of technology on faculty of elektrical engeenerig and communication. Supervisor Ing. Marie Havlíková , Ph.D.
Multimedial education interface for programming and debugging software for AVR microcontrollers
Šrajla, Josef ; Sajdl, Ondřej (referee) ; Pavlík, Michal (advisor)
Diploma thesis is concerned with programming of AVR microprocessors. Main task was development of compact environment where user can learn methods necessary for successful programming of microprocessor. It was necessary to make an application enabling interactive simulation of processor to reach this goal. User-friendly control, simplicity and low hardware demands are main advantages of this application. Only computer with internet connection is demanded. Complicated installation, usual for similar products, is avoided.
