- The use of remote laboratories in courses at university level has been reported in literature numerous times since the mid 90?s. In this article focus is on activities carried out by teachers and students, at the Upper Secondary School Level, using the remote laboratory VISIR (Virtual Instrument Systems in Reality). The Upper Secondary School, Katedralskolan in Lund, Sweden, cooperate with Blekinge Institute of Technology, Sweden, in a project that concerns the introduction of remote laboratory environment suitable for Upper Secondary School science courses. A remote laboratory in electronics has been introduced and is used as a complement to the traditional workbench in the hands-on laboratory. Significant results from the project are; 1) the great interest shown by the students for the remote experiments, 2) the students appreciation for the fact that it was not simulations but actual real experiments, 3) the remote laboratory is easy to implement for use by both teachers and students and 4) it can be used simultaneously by many students.

Tidskriftsartikel (refereegranskat)abstract
- The Signal Processing Department (ASB) at Blekinge Institute of Technology (BTH) has created two online lab workbenches; one for electrical experiments and one for mechanical vibration experiments, mimicking and supplementing workbenches in traditional laboratories. For several years now, the workbenches have been used concurrently with on-site ones in regular, supervised lab sessions. The students are encouraged to use them on a 24/7 basis for example, in preparation for supervised sessions. The electronic workbench can be used simultaneously by many students. The aim of a project known as VISIR (Virtual Systems in Reality) founded by ASB at the end of 2006, is to disseminate the online lab workbenches using open source technologies. The goal is to create a template for a grid laboratory where the nodes are workbenches for electrical experiments, located at different universities. This paper focuses on standards, pedagogical aspects, and measurement procedure requirements.

Tidskriftsartikel (refereegranskat)abstract
- Physical experiments are indispensable for developing skills to deal with physical processes and instrumentation. The Internet provides new possibilities for universities and other teaching organizations to share laboratories and increase the number of lab sessions without incurring any increase in cost. Blekinge Institute of Technology in Sweden has opened a traditional electronics laboratory for remote operation and control 24/7; it is the first of its kind. The laboratory is equipped with a unique virtual interface enabling students to recognize on their own computer screen the desktop instruments and the breadboard they have already used in the local laboratory. The research is focused on what is perceived to be the greatest challenge, i.e. to give the student laboratory experience that is as genuine as possible despite the lack of direct contact with the actual lab hardware at the same time as it allows the teacher to use existing equipment and teaching material. The goal is to produce an open international standard.

Tidskriftsartikel (refereegranskat)abstract
- This paper presents a novel and advanced remotely controlled laboratory for conducting Active Noise Control (ANC), acoustic and Digital Signal Processing (DSP) experiments. The laboratory facility, recently developed by Blekinge Institute of Technology (BTH) Sweden, supports remote learning through internet covering beginners level such as simple experimental measurements to advanced users and even researchers such as algorithm development and their performance evaluation on DSP. The required software development for ANC algorithms and equipment control are carried out anywhere in the world remotely from an internet-connected client PC using a standard web browser. The paper describes in detail how ANC, acoustic and DSP experiments can be performed remotely The necessary steps involved in an ANC experiment such as validity of ANC, forward path estimation and active control applied to a broad band random noise [0-200Hz] in a ventilation duct will be described in detail. The limitations and challenges such as the forward path and nonlinearities pertinent to the remote laboratory setup will be described for the guidance of the user. Based on the acoustic properties of the ventilation duct some of the possible acoustic experiments such as mode shapes analysis and standing waves analysis etc. will also be discussed in the paper.

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we present a way for students to access and operate laboratory equipment, controlled by a laboratory computer via a remote access program. In this way, the solution is not dependent on the specific laboratory equipment, as long as the equipment can be remotely controlled. The system can easily be altered to be used in another laboratory setup. Students are able to make reservations of experiment sessions through a web interface, which is administrated by the system administrator. The solution proposed in this paper is one way to speed up the development of remote accessible laboratories. Most of the proposed solution is based on open source software and the hardware is built on ordinary consumer parts, which makes the proposed remote laboratory architecture cost effective.

- Analysis and design are important phases in the system development lifecycle. In these phases, developers record information necessary for properly understanding the nature of the systems under consideration. We consider a particular type of system, named Remote Lab that allows both teachers and students to perform real experiments over the internet and we focus on Virtual Instrument Systems in Reality (VISIR). We describe a summarized web interface of VISIR using the Unified Modeling Language (UML). Our case study aims at identifying the requirements of VISIR and at creating a set of UML diagrams that succinctly provide enough information to both developers and users so that they acquire enough information for building a general understanding of it. Additionally, we provide elements for extending UML to better support further user interface development in VISIR.

Tidskriftsartikel (refereegranskat)abstract
- The development of tele-operated experimentation and its provision to distance learners opens new dimensions for experience-based scientific and engineering education, particularly where experiments are the core elements of teaching and learning. The finalized EU-funded project PeTEX-Platform for e-Learning and Telemetric Experimentation has developed a prototype of an e-learning platform based on the learning and content management system Moodle for the design and implementation of educational and training applications in the field of production engineering. The principle goal of this project was to establish individual and group oriented learning for different target groups like students and professional workers within a platform-system capable to serve a multi-lingual learning community. Hence, an educational model was designed which integrates the tele-operated experimentation platform with teaching content and learning activities in order to support a successful learning walkthrough for different target groups.

- With the ongoing internationalization of virtual laboratories, the integration aspect becomes more important. The meanwhile commonly accepted ’glue’ for such legacy systems are service oriented architectures, based on standardized and accepted Web service standards. We present our concept of the ’experiment as a service’, where the idea of service-based architectures is applied to virtual remote laboratories. In our laboratory middleware, experiments are represented as stateful service implementations and jobs as logical service instances of these implementations. We discuss performance, reliability, security and monitoring issues in this approach, and show how the resulting infrastructure - the Distributed Control Lab - is applied in the European VetTrend project.

- For experiments to be reproducible, it is important to have a known and controlled environment. This requires isolation from the surroundings. For security experiments, e.g. with hostile software, this is even more important as the experiment can affect the environment in adverse ways. In a normal campus laboratory, isolation can be achieved by network separation. For an online environment, where remote control is essential, separation and isolation are still needed, and therefore the security implications must be considered. In this paper, a way to enable remote experiments is described, where users are given full control over the computer installation. By automating the install procedure and dynamically creating isolated experiment networks, remote users are provided with the tools needed to do experiments in a reproducible and secure environment.

- Engineering labs play a vital role in engineering education, make science come alive, and supply students with better understanding of theories. As a result, they contribute to the improvement of their knowledge and skills. Remote labs not enable sharing of teaching resources such as devices, equipment and instrumentations between universities, but also relax time and space constraints; yet they are considered as a complementary asset to the traditional hands-on labs. This paper is concerned with a two-stage assessment of the engineering remote lab VISIR. In the first stage, the assessment investigated if the students accept to use VISIR in their future lab courses at the Faculty of Engineering at Al-Quds University in Palestine. In the second stage, a deeper analysis will be performed to compare VISIR to hands-on and simulators based on the evaluation criteria: performance, students’ retention rate and satisfaction survey.

Programming industrial robots using advanced input-output devices: test-case example using a CAD package and a digital pen based on the Anoto technology
- 2007

Tidskriftsartikel (refereegranskat)abstract
- Interaction with robot systems for specification of manufacturing tasks and motions needs to be simple, to enable wide-spread use of robots in SMEs. In the best case, existing practices from manual work could be used, to smoothly let current employees start using robot technology as a natural part of their work. Our aim is to simplify the robot programming task by allowing the user to simply make technical drawings on a sheet of paper. Craftsman use paper and raw sketches for several situations; to share ideas, to get a better imagination or to remember the customer situation. Currently these sketches have either to be interpreted by the worker when producing the final product by hand, or transferred into CAD file using an according tool. The former means that no automation is included, the latter means extra work and much experience in using the CAD tool. Our approach is to use the digital pen and paper from Anoto as input devices for SME robotic tasks, thereby creating simpler and more user friendly alternatives for programming, parameterization and commanding actions. To this end, the basic technology has been investigated and fully working prototypes have been developed to explore the possibilities and limitation in the context of typical SME applications. Based on the encouraging experimental results, we believe that drawings on digital paper will, among other means of human-robot interaction, play an important role in manufacturing SMEs in the future.
