2. ANALIZA IN SINTEZA KRMILNEGA SISTEMA VODENJA VARNOSTNIH VRAT OBDELOVALNEGA STROJAGašper Ferme, 2011, undergraduate thesis Abstract: Veliko strojev ima varnostna vrata na ročno zapiranje, zato smo v diplomskem delu analizirali in preučili, kateri avtomatski sistem odpiranja vrat bi bilo najugodneje vgraditi na takšen obdelovalni stroj. Na eni strani imamo pnevmatični sistem krmiljenja, na drugi pa hidravlični. Oba sta predstavljena posebej in modelirana, glede na izvedbo, v programu Automation Studio. Sisteme smo optimirali in merili odzive. Na koncu smo jih med seboj primerjali glede na vzdrževanje, stroške, kompleksnost izgradnje, izvedbo in enostavnost uporabe in ugotovili, da je najbolj ugodna izvedba z elektropnevmatičnimi komponentami.

3. AVTOMATIZACIJA NAMENSKEGA STROJA ZA GUMARSKO INDUSTRIJOJure Poteko, 2011, undergraduate thesis Abstract: V diplomi je prikazano projektirano pnevmatsko krmilje, ki bo vodeno preko krmilnika Allen Bradley. Stroj je namenjen za proizvodnjo avtoplaščev visokih zmogljivosti – hitrostni razred H in V ter W, velikosti od 15" do 21". Uporabljene komponente morajo biti po specifikacijah naročnika, in sicer od proizvajalcev FESTO ali PARKER, oz. drugih v primeru, da prej omenjena ne ponujata potrebnih komponent. Pri izbiri ustreznih komponent pa je poleg specifikacije uporabnika potrebno upoštevati tudi konstrukcijske omejitve. Krmilje bo projektirano in simulirano v programu Automation Studio 5.7.

4. Cost Oriented Robots for KosovoA. Pajaziti, Sh. Buza, I. Gojani, Riko Šafarič, Peter Kopacek, 2009, original scientific article Abstract: The cost of developing and operating control and automation systems is a crucial factor of productivity and competitiveness for a number of applications in manufacturing plants, quality control systems and robotics. This paper has been focused on practical use of technologies that provided significant cost reduction in operating automated systems for a variety of industrial applications and buildings/facilities operations in Kosovo. Topics that have been discussed were as following: key technologies reducing cost of automation systems; industrial applications of variety technologies, such as smart devices, wireless sensors and control systems, field robots, etc.; cost reducing engineering strategies as well as simulation of manufacturing systems and processes form cost estimation.
Keywords: robots at SMEs, manufacturing automation, cost oriented automation

5. A model of data flow in lower CIM levelsIgor Drstvenšek, Ivo Pahole, Jože Balič, 2004, original scientific article Abstract: After years of work in fields of computer-integrated manufacturing (CIM), flexible manufacturing systems (FMS), and evolutionary optimisation techniques, several models of production automation were developed in our laboratories. The last model pools the discoveries that proved their effectiveness in the past models. It is based on the idea of five levels CIM hierarchy where the technological database (TDB) represents a backbone of the system. Further on the idea of work operation determination by an analyse of the production system is taken out of a model for FMS control system, and finally the approach to the optimisation of production is supported by the results of evolutionary based techniques such as genetic algorithms and genetic programming.

6. Relational database as a cogitative part of an intelligent manufacturing systemIgor Drstvenšek, Mirko Ficko, Jože Balič, 2004, original scientific article Abstract: An intelligent manufacturing system is intended to produce one or more subjects that it is designed for in an optimal way. This means that it has to find a proper production process to produce the subject in an optimal way. The manufacturing system can be called "intelligent" when it is able to find applicable optimisation criteria upon its past experiences thus improving its performance in future. Therefore, an intelligent manufacturing system needs capabilities to store data and make decisions upon them. Such a "brain" can be established by a proper design of a technological database and its database management system (DBMS). Examining all constitutive parameters of a work operation a model of a production process organization can be made, which can serve as a basis for a suitable database design. In addition, an application programme that will check the existence and availability of work operations in the database has to be added to the DBMS. What remains are some optimisation criteria upon which we will choose an operation among suitable and available work operations. This task is fulfilled by a genetic algorithm optimisation technique that would consider work operations' data as parameters of optimisation and on this basis search the optimal one out of the set of available operation.

7. OPC-driven data exchange between MATLAB and PLC-controlled systemStojan Peršin, Boris Tovornik, Nenad Muškinja, 2003, original scientific article Abstract: Many manufacturing, and mechatronics systems, are controlled by PLCs and SCADAsystems. These systems provide very limited possibilities for research, optimisation, testing and simulation. The main advantage of this proposed solution, which uses OPC, is an integration of the numerical, computational and graphical strengths of MATLAB with the robustness of industrial systems. The experimental setup, the processing of the data and the results are presented with particular emphasis on student use in a laboratory environment but the techniques employed in the experiments will likely to be seen by the students in their subsequent employment after completion of their college careers.

8. The Internet of Things Communication Protocol for Devices with Low Memory FootprintSašo Vinkovič, Milan Ojsteršek, original scientific article Abstract: This paper describes a new communication protocol named XMC which is designed for the transmission of messages between an embedded device and a remote system. A new markup language called XMDD has also been developed and is used to describe the functional profile of the embedded device. The main advantage of the XMC communication protocol is its flexibility and independence from the device type. It is suitable for communication with devices that have a curtailed amount of working memory (a few kB) and limited computing power, i.e. 8-bit or 16-bit microcontrollers. Messaging between the embedded device and the remote systems is done without any interference with the basic source code of the embedded device, thus allowing access to all functionalities and features of the connectable embedded device and is based on the functionality dictionary and built-in features of an embedded device. It also maintains a low production price for the embedded device and from the programming point of view provides a transparent and flexible upgrade of the hardware and software without any redundancy input.
