A Hardware Platform for a Promotional Robotic Vehicle
Koláčný, Michal ; Burian, František (referee) ; Jirgl, Miroslav (advisor)
This thesis serves as a feasibility test for the construction of a robotic vehicle, where its autonomous movement will be provided by a camera and QR code scanning, for the company B:TECH. Specifically, it deals with the interaction of the hardware platform of the robotic vehicle together with selected electrical components. It describes the design of the structure printed on a 3D printer and its electrical and mechanical components enabling movement. Furthermore, the work focuses on the selection of suitable electrical components related to the safety of operation in the form of sensors. A necessary part is also the control and coordination of the movement of the vehicle using control microcontrollers. Specific components and equipment are described in the following chapters. The result of the thesis is the creation of a hardware concept of an autonomous robotic vehicle.

An Innovative Control System for Water Supply Management at a Farm
Doležal, Aleš ; Sýkora, Tomáš (referee) ; Jirgl, Miroslav (advisor)
The thesis deals with the implementation of an innovative control system for the management and supply of water to the farm. For the innovation, fiber optic communication between the main switchboard and the poles at the wells was chosen. Furthermore, the thesis deals with the selection of components and sensors for the implementation of the system. The program that controls the whole application is written in ladder language in a development environment from Unitronics, from which the control PLC is also supplied.

Visualization of exit inspection of the production line for seats
Čambál, René ; Jirgl, Miroslav (referee) ; Sýkora, Tomáš (advisor)
This thesis focuses on the design of an output control system for the production line of automotive seats at Lear Corporation Seating Slovakia. The approach to line design is based on the principles of lean manufacturing, emphasizing efficiency, quality, and optimization of manufacturing processes. The main goal of this thesis is to create software and HMI (Human-Machine Interface) visualization for virtual testing in the pre-series phase of the project and subsequent real-world use by individuals in the manufacturing environment. This approach enables effective identification and resolution of potential issues and optimization of manufacturing processes in the early stages of development. Additionally, attention is given to the process design of the line to achieve an optimal balance between speed, precision, and flexibility. The proposed line design aims to maximize manufacturing efficiency, minimize waste, and ensure high product quality. The overall outcome of this thesis represents a comprehensive and integrated approach to the design of a conveyor line for automotive seats, serving as a model for future projects in the automotive industry.

Control System and Visualization for a Promotional Robotic Vehicle
Lázničková, Jana ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
The thesis focuses on the software part of an autonomous robotic vehicle, designed for promotional purposes of the B:TECH company. As this is a feasibility test, the result of the work serves only as an idea of a suitable software design for the robotic vehicle with the possibility of using this control software in real operation. The possibilities of data exchange between the robotic vehicle and the master control system are presented. The proposed concept describes the control software ensuring cooperation between real and simulated vehicles in operation. Furthermore, a platform for a visualization application is designed to monitor and control the movement of the vehicles and transported shipments. Each vehicle in the application is updated with its current status.

Learning dictionaries for sparse signal representation
Ettl, Ondřej ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
This thesis focuses on examining data from measurements on a pressure mattress that uses a 30 × 11. sensor grid to collect. This data will be used to train and test learners dictionaries that are built using sparse signal representation. Applied learning methods include the method of optimal direction (MOD) and K-SVD, which uses singular decomposition. The resulting dictionaries for different numbers of iterations or atoms are then used to classify and reconstruction of the test data. Cross-validation determined the true positive ratio of the models, which was then compared with conventional classifiers. These models included Decision trees, KNNs and SVMs. Finally, the ability of the learning dictionaries was verified to filter the error in the corrupted image.

Multiloop dynamical models of human driver
Čelko, Jakub ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
The thesis is focused on modelling human-machine systems, where a human operator controls a vehicle. The result of the work is a comparison of the prediction capabilities of chosen multiloop and single-loop human driver models. These models are applied in scenarios where, in addition to the lane change forcing function, there is also a disturbance signal that affects the vehicle’s motion. The parameters characterising the human dynamics are extracted from the model of the whole loop, defined as a discrete state-space model. The thesis also contains research on driver models, description of the used vehicle simulator and the Unreal Engine 4 environment used for its implementation. Documentation of implemented disturbance signals that act as a fault at the input of the regulated system is also presented. The identification results on the measured data suggest that the models relying on a single transfer function are losing prediction capabilities in scenarios, where the disturbances affect the vehicle. In such cases, the multiloop models with the same number of parameters are able to capture human behaviour more accurately.

FLATcon system – CCD detection of media meters with RF communication
Lancz, Michal ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with designing the concept of battery powered miniature microcontroller system based on CCD detection of media meters. The FLATcon design concept contains the necessary inputs and outputs for communication with microcontroller and with peripheral devices. The aim of the thesis is to detect the state of a media meter equipped with an analogue dial, to save the scanned image along with the scanning time and forwarding through the RF module. The bachelor thesis describes FLATcon system design, soldering and supplying the system and testing peripheral devices.

Reliability of Technical Systems
Jirgl, Miroslav ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This thesis deals with a reliability of technical systems. It is divided into four main parts. The first part deals with the mathematical description of reliability. Probability and statistics are used for this description. This part includes the definition and properties of random events, the description of discrete and continuous random variable and its distribution. The second part contains the definition and expression of reliability, types of faults in the digital circuits and the reliability of electronic components. This part introduces into problems of reliability. The third part includes making the reliability diagrams and reliability analysis. Each method is briefly described here. Further advantages and disadvantages of using each method are given here. The two most widely used reliability analysis - Failure Mode and Effect Analysis - FMEA (resp. FMECA) and Fault Tree Analysis – FTA are described in a greater detail. The last part focuses on an example of calculation of reliability. An analyzed object is Universal Charger NiMH and NiCd batteries. Reliability is analysed by block diagram, FTA and FMEA.
