Navigation of UAV in GNSS denied area
Pintér, Marco ; Marcoň, Petr
This paper examines the concept of navigation of of Unmanned aerial vehicle (UAV) in three-dimensional space using visual odometry. In the near future navigation of the UAV without GNSS is becoming a critical part of autonomous navigation systems, using information from on-board cameras to estimate the UAV’s movement and position. In the paper, different types of visual odometry, sensors for visual odometry, components of the implementation, and scenarios of usage. For the development and future application we utilize widely used Robotic Operating System (ROS).

Simulator of IEC 60870 communication
Calábek, Tomáš ; Bohačík, Antonín
The power industry’s evolution hinges on efficient and reliable transmission, distribution, and control of electricity, increasingly facilitated by remote monitoring and control systems. Among these, SCADA technologies stand out, enabling centralized supervision and management of energy infrastructure. Central to these systems are communication protocols such as protocols from IEC 60870 standard, facilitating data exchange within power networks. This paper introduces a communication simulator based on IEC 60870-5-101/103/104 protocols. Our simulator for IEC 60870 is capable of simulating all three mentioned protocols on the client-server principle. It can simulate both balanced and unbalanced transmissions, adjust transmitted data, set quality bits, and much more. Our simulator was tested in a virtual environment.

Darkmarket Forensics
Dolejška, Daniel ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
Overlay networks (like Tor or I2P) create a suitable environment for criminality to thrive on the Internet. Dark marketplaces (a.k.a. cryptomarkets) are one such example of criminal activities. They act as an intermediary in the trade of illegal goods and services. This project focuses on forensic analysis of such web services and subsequent extraction of non-trivial information about the realised orders and payments from selected marketplaces. The main goal is to pinpoint the time interval when an order has been completed on selected marketplaces and its following correlation with cryptocurrency blockchains. The implemented program provides fully automated non-stop monitoring of selected cryptomarkets. That, under certain conditions, allows detection of realised purchases, detailed product and vendor monitoring and collection of various meta-data entries. Law enforcement agencies can use acquired data as support evidence regarding the operation of selected cryptomarkets and their vendors. The obtained information can also indicate current trends in products supply and demand.

Programmable Relay in the Application of Automated Production Tests
Ondruška, Arnošt ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
This Bachelor thesis describes the design of a programmable relay and its application in the automation of production tests. First, commercially available, professionally produced relays are presented and selected bachelor and diploma theses related to the issue of automated measurement of electrical quantities are summarized. The thesis presents the design of an automated test workplace containing measuring devices, laboratory sources and other accessories controlled by a programmable relay via RS 232, with minimal human intervention. A block diagram is presented in the work, and individual blocks are subsequently described in detail. The output of the work is the creation of a custom design of a programmable relay and its use in automated measurement and control of the properties of serially produced industrial sources for the energy industry. The test program itself is written in the BASCom-AVR language.

Visual inspection of PCB installation
Cherniaev, Egor ; Dobrovský, Ladislav (referee) ; Matoušek, Radomil (advisor)
Vizuální kontrola DPS je významnou oblastí rozvoje aplikované informatiky v elektronickém průmyslu. Předložená práce je věnována teoretickému průzkumu používaných algoritmů pro identifikaci defektů montáže komponent na desky plošných spojů a praktické implementaci systému pro automatizaci obecné vizuální kontroly. Průzkum je primárně zaměřen na případy chybějících komponent, orientaci kapacitorů a kvalitu potisku na desce. Praktická část je věnována návrhu a implementaci vlastního systému na frameworku ROS2. Práce popisuje různé aspekty vývoje a použití daného systému. Součástí práce je veřejně přístupný dataset s více než 300 snímky DPS získanými průmyslovou kamerou. Závěrem je provedeno hodnocení přínosu předložené práce.

Design of a smart house control system
Ovesný, David ; Burian, František (referee) ; Fiedler, Petr (advisor)
This bachelor thesis deals with the comprehensive design solution of a smart home using Loxone technology. Through the appropriate implementation of sensors, actuators, and a central control system, a comprehensive solution for home automation processes is proposed. The theoretical part introduces Loxone technology and briefly compares it with the competing ABB free@home technology. The practical section involves the selection of suitable hardware components and the description of control algorithms. The conclusion of the thesis is dedicated to a cost comparison with the competing technology.

Application for Creating Extended User Interfaces Using Floating Windows
Šediba, Jakub ; Zaklová, Kristýna (referee) ; Hynek, Jiří (advisor)
This thesis aims to address problems related to the necessity to often switch active windows to access information from external sources while working. These problems are addressed by creating a modular cross-platform application for Windows and Linux operating systems. This application allows users to develop multi-window modules which can then be combined to create a desired extended user interface overlaid above other windows. Outside of this functionality, access to automation through global keyboard shortcuts, file-system monitoring and input device simulation is provided. The developed application uses the Tauri framework and a combination of web technologies with the Rust programming language.

Production technology for a vacuum pump component
Horák, Adam ; Kalivoda, Milan (referee) ; Zemčík, Oskar (advisor)
The bachelor's thesis focuses on the design of a new or alternative technology for the component of the orbital scroll wheel 10i for the vacuum pump nXDS10i. The component is made of an aluminum alloy. The aim is to transition to a higher level of automation compared to the original technology, with the implementation of High-Speed Cutting (HSC) machining. The thesis includes an introduction and analysis of the component, including information about the alloy used, an analysis of the original technology, and its variants for optimization. This is followed by the proposal of a new technology and automation design, meeting the conditions set by the manufacturer of the component. The proposal of the new technology includes the design of a new technological process and clamping method. The thesis also includes a technical and economic evaluation of the original technology, the optimized original technology, and the new technology.
