RAZVOJ KRMILNEGA PROGRAMA ZA OKOLJE OKEN ZA NAVIGACIJSKO NAPRAVO WII
Sašo Horvat, 2009, diplomsko delo

Opis: V diplomski nalogi opisujemo uporabo periferne naprave Wii Remote za osebni računalnik. Pripomoček je namenjen za uporabo igralne konzole Wii (proizvjalec Nintendo). Ker naprava podatke prenaša preko tehnologije modri zob (angl. Bluetooth), jo zlahka uporabimo tudi za komunikacijo z računalnikom. V delu je opisana strojna oprema, ki jo pripomoček vsebuje, kot tudi komunikacija, ki je potrebna za njeno uporabo. Naprava spada v razred HID (Human Interface Device), kar omogoča poenostavljeno komunikacijo, saj že sam operacijski sistem poskrbi za en del le-te. V delu opisujemo uporabo ene izmed ključnih tehnologij, ki jo uporablja naprava WII Remote. To je infrardeča kamera. S pomočjo te tehnologije simuliramo premik miškinega kazalca v okolju Oken. Kot popestritev predstavljamo zmožnosti uporabe naprave. Osredotočili smo se na strelsko računalniško igro.
Ključne besede: periferna naprava, naprava WII Remote, aplikacija za navigacijo Oken, krmilni program

Suzana Uran, Darko Hercog, Karel Jezernik, 2006, izvirni znanstveni članek

Opis: In the paper a remote lab experiment RC oscillator used to support Web based learning, to support learning by doing, to learn control design and to minimize the gap between theory and practice is presented. The experiment was designed with a special care for visualisation of important control design parameters in Bode plot and Root-Locus diagram. The experiment is based on MATLAB, LABview and DSP2 learning module. Using RC oscillator experiment RC circuit step response based or sinusoidal response based analysis, P controller design using Bode plot or Root-locus, relations between control design parameters and control performance and discrepancy between theory and practice could be covered. A homework based on RC oscillator experiment is presented and obtained experiences are discussed.

Software and equipment for remote testing of sensors
Barbara Brezovec, Vojko Matko, 2007, izvirni znanstveni članek

Opis: An improved approach for remote testing of elements and systems is presented in this article. To ensure high reliability of products, tests must be done in the production phase to detect possible errors in working mode. Because environmental testing involves long-term processes the possibility of remote observation and remote controlling of tests is very useful solution. The concept is to connect the testing chamber with a personal computer, create a reliable driver and control it remotely over the local network or Internet from other client. It is designed for performing tests on wide area of sensors and sensor based systems.

Improvement of the Peyravian-Jeffries`s user authentication protocol and password change protocol
Marko Hölbl, Tatjana Welzer-Družovec, Boštjan Brumen, 2008, izvirni znanstveni članek

Opis: Remote authentication of users supported by passwords is a broadly adopted method of authentication within insecure network environments. Such protocols typically rely on pre-established secure cryptographic keys or public key infrastructure. Recently, Peyravian and Jeffries [M. Peyravian, C. Jeffries, Secure remote user access over insecure networks, Computer Communications 29 (5-6) (2006) 660-667] proposed a protocol for secure remote user access over insecure networks. Shortly after the protocol was published Shim [K.A. Shim, Security flaws of remote user access over insecure networks, Computer Communications 30 (1) (2006) 117-121] and Munilla et al. [J. Munilla, A. Peinado, Off-line password-guessing attack to Peyravian-Jeffries`s remote user authentication protocol, Computer Communications 30 (1) (2006) 52-54] independently presented an off-line guessing attack on the protocol. Based on their findings we present an improved secure password-based protocol for remote user authentication, password change, and session key establishment over insecure networks, which is immune against the attack.

Bilateral teleoperation by sliding mode control design approach
Aleš Hace, 2008, izvirni znanstveni članek

Opis: Sliding mode control has been used extensively in robotics to cope with parameters uncertainty, model perturbations and system disturbance. Bilateral robotic teleoperators are often required to provide a haptic interaction in telerobotic applications in which human kinesthetic sense is stimulated locally by remote environment. The paper deals with bilateral control for a force-reflection master-slave telerobotic architecture. It involves a short overview of basic bilateral modes. Chattering-free SMC design procedure for force-reflecting master-slave teleoperator is presented. The proposed bilateral control scheme was experimentally validated for a 1DOF master-slave teleoperator.

Implementation, effectiveness and experience with remote laboratory in engineering education
Andreja Rojko, Matjaž Debevc, Darko Hercog, 2009, izvirni znanstveni članek

Opis: Modern educational methods bring many new challenges from the pedagogical, as well as from the technical aspect. One of the more significant is the integration of information and communication technology into the educational process. These is particularly noticeable in the engineering education where the requests of the industry for a faster and more efficient acquisition of knowledge and practical skills lead to a constant search for new solutions in the learning process which would attract and motivate students, as well as be user friendly. This is especially difficult to be reached with the practical education which is usually composed of laboratory exercises that are bound to a specific time and place. One of the possible solutions are the remote laboratories which offer the possibility of the implementation of real remote laboratory experiments in the educational institutionsć laboratories and, therefore, enhance the studentsć knowledge and capability for dealing with some technical problems without the need for their physical presence in the laboratory. In the article, the example of a successful implementation of the remote laboratory in the field of engineering, developed and operating in the Moodle environment, is presented. The laboratory does not only represent the framework for the experiment implementation, but it also offers courses with complete documentation, therefore courses can be performed on distance. As an example, the case of the most widely used course from remote laboratory is presented, i.e., the ĆControl of nonlinear mechanismĆ course. Special attention is given to the description of the booking process for remote experiments, the execution of remote experiments and the applied user interface. The evaluation of the interface usability from the point of view of end users was performed via the acknowledged SUMI method. Additionally, another questionnaire was prepared in order to investigate the studentsć opinion about working in the remote laboratory. The results have shown that the presented remote laboratory is user friendly and accepted by both teachers and students as a suitable and interesting supplement to the conventional laboratory exercises.

Remote controlled laboratory as a modern form of engineering education
Uroš Župerl, Mateja Ploj Virtič, 2013, izvirni znanstveni članek

Opis: Technological development enables many benefits and improvements with regard to the educational process. This paper discusses the development of remote laboratory architecture for web-based programming and control of a passenger lift located at the Faculty of Mechanical Engineering, University of Maribor (UM FME). A dedicated web page provides users with the opportunity to learn how to programme and control a programmable logic controller (PLC) from remote sites. Remote-controlled experiments involving additional visual support have similar learning effects compared to practical work in a laboratory, the difference being that students acquire additional technological knowledge in the latter. This paper presents, among other things, the details regarding the development of the respective laboratory for remote control of lift operation. In conclusion, the article critically examines the advantages and disadvantages of the here presented remote-controlled laboratory.

Web based education tool for neural network robot control
Jure Čas, Darko Hercog, Riko Šafarič, izvirni znanstveni članek

Opis: This paper describes the application for teleoperations of the SCARA robot via the internet. The SCARA robot is used by students of mehatronics at the University of Maribor as a remote educational tool. The developed software consists of two parts i.e. the continuous neural network sliding mode controller (CNNSMC) and the graphical user interface (GUI). Application is based on two well-known commercially available software packages i.e. MATLAB/Simulink and LabVIEW. Matlab/Simulink and the DSP2 Library for Simulink are used for control algorithm development, simulation and executable code generation. While this code is executing on the DSP-2 Roby controller and through the analog and digital I/O lines drives the real process, LabVIEW virtual instrument (VI), running on the PC, is used as a user front end. LabVIEW VI provides the ability for on-line parameter tuning, signal monitoring, on-line analysis and via Remote Panels technology also teleoperation. The main advantage of a CNNSMC is the exploitation of its self-learning capability. When friction or an unexpected impediment occurs for example, the user of a remote application has no information about any changed robot dynamic and thus is unable to dispatch it manually. This is not a control problem anymore because, when a CNNSMC is used, any approximation of changed robot dynamic is estimated independently of the remote's user.
