  • The user interface is the virtual end-user workbench that handles all the lab administration process. It is a web site that runs on the user’s web browser and usually requires a server-side programming language to retrieve user’s data from database, along with a Graphical User Interface (GUI), which is built by an animation technology embedded in the HTML code to resemble the real lab workbench. The webserver hosts the web site and the database files and sends the user requests to the lab server in the form of XML messages through TCP/IP model over HTTP layer. The lab server hosts the instrumentation control software and it is connected directly to the instruments. The instrumentation control software (usually Matlab or LabVIEW) sends commands to the object under control with regarding to the received requests from the user.

  • Nowadays, a remote laboratory of a university is scarcely reused by other universities due to the lack of information about the laboratory. The Lab2go project was launched to fill this gap. It is a web portal that acts as a repository and provides a common framework for on-line laboratories providers all over the world. The laboratories with all their related information, running projects, status, language, scientific field, access url, difficulty property, etc. are added with metadata by using semantic web technologies, to facilitate their allocation and precise the searching criteria rather than the traditional available searching tools that are oriented to the keyword. This allows individuals and researchers to find information about certain types and architectures of laboratories in a specific field all over the world with an intelligent way. Terminologies are adopted from metadata such as Dublin Core and Learning object metadata (LOM). Lab2go, however, is metadata architecture and it is not structured to provide access to the on-line laboratories.
  • A LMS is a software application that facilitates the provision of theoretical online classrooms by means of integrated features and tools such as administrative tools, synchronous and asynchronous communication tools, assessment and tracking tools, multimedia sharing tools, and standard compatibility. Even though, most of the features provided by LMS are of crucial importance to practical sessions. LMS, however, is confined to theoretical resources and doesn’t support their practical counterparts.The goal is to make use of all the services provided by open source LMSs such as Moodle, DotLRN and Sakai, and apply them in the remote practical lab sessions. As well, to make use of standards such Sharable Content Object Reference Model (SCORM), and deliver remote experiments in form of SCORM to be launched at any compatible LMS. Thus, several initiatives have been launched in order to integrate remote laboratories into LMS including LiLa, Marvel, and the middleware architecture developed at UNED.
  • Shared access to laboratories is one of the most often raised justifications for the use of remote labs. RLMSs are generic educational systems that provide a common portal through which managed remote laboratories can be accessed, along with other administrative and educational services such as booking, assessment, tracking, and communication tools.RLMSs should be agnostic with regard to the remote laboratory design in order to support the widest range possible of remote laboratories. It is claimed that this can lead to improved utilization levels, shared costs, and access to a much broader range of laboratory apparatus.Approaches for remote labs integration with RLMSs includes Sahara, weblabDeusto, and iLabs.

    2. 2. The implementation of practical sessions in engineering education:• Paves the way for students to be familiar with the instruments and thus, with the industrial real-world.• Augment the learning outcomes by strengthening the understanding of scientific concepts and theories.
    3. 3. Remote laboratories facilitates the practical sessions availabilityproviding on-line ubiquitous workbenches unconstrained by neithertemporal nor geographical considerations.
    4. 4. Remote laboratories are those laboratories that can be controlled andadministrated online. They differ from the virtual simulatedlaboratories as they are interacting with physical instruments.
    5. 5. The common generic architecture design of today’s remote laboratoryfor industrial electronics applications.
    6. 6. Recently, remote laboratories have been developed at multipleuniversities and adopted in engineering education. Furthermore, someof these laboratories are replicated at many universities such as theelectronic circuit’s remote labs: NetLab, VISIR, and labs based on NIELVIS II.
    7. 7. This was the commence of a new mainstream which advocates a betterremodeling of those laboratories to allow their allocation, sharing amonguniversities, and their communication with other heterogeneoussystems, e.g., Learning Management Systems (LMS).
    8. 8. In this context, numerous sharable educational architectures for remotelabs integration have emerged such asLiLa, Lab2go, ISILab, DCL, WebLab Deusto, iLab (ISA), and Labshare(Sahara).

    12. 12. GOLC: Global Online Laboratory Consortium• The GOLC consortium is focused on promoting the development and sharing of, and research into remotely accessible laboratories for educational use.• The GOLC partners include most of the pioneers in remote laboratories development and deployment. http://online-lab.org/
    13. 13. GOLC: Global Online Laboratory Consortium• The trend in researching within GOLC is to create standard APIs that allows communication with different remote laboratory systems that adhere to this standard.• For instance, users of Sahara could access experiments integrated in iLab and vice versa.
