Svertoka, Ekaterina ; Martian, Alexandru (referee) ; Digulescu-Popescu,, Angela (referee) ; Lohan, Elena Simona (referee) ; Hošek,, Jiří (referee) ; Burget, Radim (advisor)
Tento výzkum kombinuje teoretické poznatky, simulační studie a praktické experimenty s cílem prozkoumat oblast průmyslových nositelných zařízení se zaměřením na zvýšení přesnosti jejich lokalizace pomocí technologie LoRaWAN. Práce vedla k vytvoření dvou klasifikací funkcí a metrik průmyslových nositelných zařízení a 7 volně přístupných datových sad LoRaWAN v různých prostředích (vnitřních, venkovních a podzemních). Kromě toho práce provádí komplexní posouzení přesnosti lokalizace pomocí více přístupů, analyzuje vliv proměnných z měřicí kampaně a technik zpracování dat. Dále navrhuje úpravy algoritmu k-NN, které spolu s metodami předzpracování vedou ke zvýšení přesnosti o 17,2 % ve srovnání s původním benchmarkem. Navržené algoritmy, ověřené na souborech dat LoRaWAN, nabízejí potenciální využití v různých oblastech. Studie uzavírá validaci lokalizace na bázi LoRaWAN s přesností 2,6 m v interiéru a 4 m v exteriéru, což naznačuje, že ačkoli lokalizace na bázi LoRaWAN není tak přesná jako u předních technologií, lze ji využít v odvětvích, jako je logistika, zemědělství a inteligentní výroba, kde není absolutní přesnost nezbytná.

AAS interpreter for testbed I4.0
Chmelař, Luboš ; Kaczmarczyk, Václav (referee) ; Baštán, Ondřej (advisor)
This bachelor thesis presents an innovative approach to integrating the Asset Administration Shell (AAS) model into an embedded system that is a key part of the Industry 4.0 testbed - Barman. In this context, the AAS interpreter acts as a product agent. The paper begins with a detailed description of the concepts and terminology associated with this topic. This is followed by a detailed analysis of existing and new versions of the universal NFC reader hardware. The main part of the thesis focuses on the design of the AAS model, which is then implemented in the firmware of the microcontroller. This process also included the creation of an OPC Unified Architecture (OPC UA) server, which was used to thoroughly test the overall system. The results of the testing confirmed the successful implementation and functionality of the system. All theoretical scenarios were run according to the proposed AAS model, confirming the success of this approach. Thus, this work represents a significant contribution in the field of embedded system design in the context of Industry 4.0.

DESIGN AND APLICATION OF COLLABORATION ROBOTS ACCORDING OF I4.0
Salaj, Jakub ; Szabari, Mikuláš (referee) ; Knoflíček, Radek (advisor)
Presented bachelor’s thesis deals with collaborative robots and their application in manufacturing with a focus on the implementation of Industry 4.0 principles. In the theoretical part of the thesis, a system analysis of the robotization of production processes by collaborative robots was carried out, as well as a system analysis of cobots as a technological system and the requirements that are set by the relevant standards for their safe operation. In the literature review, a range of design solutions offered by three major manufacturers of cobots and end effectors were demonstrated. The main research objective was to describe successful implementations in practical manufacturing applications. A sub-objective of this thesis was to evaluate the cobot workplace in the context of Industry 4.0. The evaluated workplace was a station for measuring the electric resistance of the fuel-filter during its production, whose operation was described and evaluated by means of a SWOT analysis. In the conclusion of the thesis, based on the obtained findings, an overall evaluation of the monitored issue and recommendations for its further development were formulated.

Use of an automatic camera system for assembly quality control
Rajnštajn, Jakub ; Hejkrlík, Lukáš (referee) ; Zháňal, Lubor (advisor)
The presented thesis is focused on automation of the assembly quality inspection at the assembly hall M1 in Škoda Auto a.s., Mladá Boleslav. In the first part, the main elements of Industry 4.0 are mentioned, especially artificial intelligence and machine learning, then the project Direct Quality Feedback is introduced, which is a good example of Industry 4.0 in Škoda Auto. The next section shows selected camera-based inspections operating across industrial enterprises. Thereafter, individual locations within the assembly area on the M1 hall, that are potentially suitable for the installation of an automated inspections, are presented, with three of them selected for realization. First of them is wheels inspection, where the solution utilises both hardware and software made by the KEYENCE company. The second case is the inspection of door panels, where the evaluation logic and the individual parts to be inspected have been determined, but till the handover of this thesis, the project wasn’t finalised due to ongoing negotiations over investment and regular overhead costs funding. The last use case is the damper cover inspection, which was chosen to demonstrate a solution that will be easily transferable within the plant and adjustable to another inspection area in a short time frame. This has been implemented in two ways – the first uses Basler's Pylon vTolls software, the second uses MATLAB.
