Modernization of the manipulator control unit for the placement of magnetic points
Adámek, Adam ; Appel, Martin (referee) ; Formánek, Martin (advisor)
This work is being taken up by upgrading the manipulator control unit. It is a so-called pick and place minupulator with CNC machine elements that places magnetic points on a film. On the manipulator, Arduino MEGA control unit with RAMPS v1.3 shield and control computer will be supplemented with Raspberry Pi microcomputer and a camera that will recognize QR codes on individual foils and accordingly select the appropriate program for placing the aformentioned magnetic points. The initial state of the manipulator will be assessed, its control unit and the pneumatic the system responsible for the transmission and placement of the magnetic points. The next section will describe the design of the new control, the use of the open-source G-code interpreter PyCNC, the setup of this software and also its incorporation with the already existing elements on the manipulator such as limit switches and solenoid valves. The last part of the thesis deals with the comparison of the achieved result, whether it is the functionality of the manipulator and its improvement, or the aesthetic aspect of installing the Raspberry Pi and the camera module on the manipulator. Also, the turn-on time and the duration of one cycle of placing the magnetic points on the film of the manipulator will be compared.

Implementation of a MitM probe on the platform RPi
Nekula, Štěpán ; Holop, Patrik (referee) ; Tamaškovič, Marek (advisor)
Cílem této práce je implementovat síťovou sondu pro monitorování šifrovaného síťového provozu. Navržená síťová sonda využívá útoku Man-in-the-Middle (MitM) pro zachycení a získání přístupu k šifrovaným datům. Základem sondy je platforma Raspberry Pi, na které běží software SSLproxy, jež zprostředkovává zachycování a dešifrování dat ze sítě. Tyto data jsou následně prohledávány pomocí detekčního systému hrozeb Suricata. Výkon sondy byl testován detekcí simulovaných útoků, jako je šíření nebezpečných souborů a síťové útoky. Tato práce poskytuje nástroj pro další výzkum v oblasti monitorování šifrovaných sítí a detekci hrozeb v šifrované komunikaci.

RF monitor tool
Hűbl, Filip ; Petyovský, Petr (referee) ; Valach, Soběslav (advisor)
This bachelor thesis investigates the detection of active WiFi and Bluetooth devices via a Raspberry Pi mini computer using Kismet software. Monitoring is performed in the 2.4 GHz and 5 GHz bands. The thesis discusses in detail the principles of operation of these technologies and methods of their possible detection. The results obtained provide information on the total number of active devices identified during the measurements, the movement of these devices and these devices are further categorized according to their type.

Post-quantum Secure Communication in IoT
Goldshtein, Daniil ; Ricci, Sara (referee) ; Malina, Lukáš (advisor)
Tato práce se zaměřuje na současný stav post-kvantové kryptografie a její využitelnost v omezeném prostředí internetu věcí. V teoretické části stručně popisuje aktuálně známé typy post-kvantových algoritmů a analyzuje jejich nejlepší implementace, buď již doporučené, nebo té, které jsou nejbližší pro další standardizace. Zaměřuje se také na existující výzvy a omezení týkající se Internetu Věcí. Praktická část této práce je věnována srovnání více knihoven z hlediska jejich modularity, účinnosti zdrojů, podpory a výkonu při provozu se standardizovanými post-kvantovými algoritmy. Dále je věnována vývoji funkční implementace řešení poskytující ověření dat pomocí kvantově odolného digitálního podpisu a jejích šifrování. Výsledky všech testů jsou systemizovány v tabulkách. Závěr práce obsahuje závěrečnou analýzu a shrnutí výsledků, dosázených pomoci vyvíjené implementace.

Optical and mechanical tracking of a moving object
Chaloupka, Radim ; Zemčík, Tomáš (referee) ; Honec, Peter (advisor)
The bachelor's thesis deals with the design of a pan-tilt platform with a camera, the design of controllers for its control, and the design and implementation of algorithms for the detection of predefined, moving objects. The task of the system is to find the object on the scene and maintain its position so that it is always in the center of the image sensor. The work uses the C++ programming language and Raspberry Pi hardware. PS and PSD controllers designed by the Ziegler-Nichols method are used for pan-tilt platform positioning, and interest point detection methods implemented in OpenCV libraries are used for optical tracing.

Data Concentrator of 3D Printer's Sensors and Devices
Vaculík, Samuel ; Rusnák, František (referee) ; Arm, Jakub (advisor)
The bachelor thesis consists of designing and implementing a system for collecting data related to 3D printing. The aim is to define the variables suitable for measurement, select sensors for the measurements and implement them on the printer. The next point is the design and implementation of data acquisition from the printing firmware Klipper for collecting print data. Then the task is to implement the software for processing data from the individual measurement sources, including data flow analysis in the system.

Design and construction of a controller for automated calibration of vacuum gauges
Kuchař, Matěj ; Králík, Jan (referee) ; Appel, Martin (advisor)
The aim of this work is to accelerate and enhance calibration, as previously a mechanical valve was used to adjust the desired pressures. To achieve automation, a system utilizing ADS 1256 for reading analog signal, EVR 116 for regulation, and standards for pressure measurement during calibration was designed and implemented, with the entire system controlled by Raspberry Pi. The results indicate that the controller performs very well but struggles with low pressures, which are, however, caused by imperfections in the apparatus.

Vestavěný systém pro příjem audiostreamů na historickém radiopřijímači
Jirgl, Karel ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The aim of the work is to create an embedded device on Raspberry Pi or ESP32 platform, which will allow to play audio streams on historical radios according to their functionality, either by interfering with their electronics, or by simulating FM and AM broadcasts using SDR or a created transmitter. The result is a device controlled via a web application allowing audio streams from SD card, internet, Bluetooth or available FM and DAB broadcasts to be played on historical radios.

Control and acquisition of data from camera sensor OV2312
Kováč, Dávid ; Kříž, Petr (referee) ; Přinosil, Jiří (advisor)
This bachelor thesis deals with the implementation of a driver for the camera sensor OV2312 into the libcamera framework, with the creation of an API interface that allows direct frame capture from a camera in the C++ language and with the creation of a program for demosaicing raw data from the camera sensor for the Raspberry Pi platforms. The aim of this thesis is not only the creation of software that would allow the camera sensor OV2312 to work with Raspberry Pi computers, but will also provide extended control options. The theoretical part describes the single board computers Raspberry Pi, the Libcamera library, the demosaicing process and the troubleshooting procedure. The output of the thesis is a modified Libcamera library that allows the user to capture images and change the parameters of the camera sensor. The created library for direct access to the camera in the C++ language allows to expand the capabilities of the camera sensor. The program for demosaicing provides the user the ability to convert raw data into images.
