“…Gravier et al discussed in [3] the state of art about remote laboratories paradigms. And more recently, Orduna, in his doctoral thesis presented in depth, a way towards "Transitive and Scalable Federation Model for Remote Laboratories" [4] and Tawfik [5] also confirms, as we explained in [6], that the preferred approach for educational remote laboratory currently used in the world, is that of the composition of web services and the aggregation of modular components that we call learning objects.…”

Abstract-ThisIn this paper, we will present and compare the typology of online labs now accepted in the various standardization of online laboratory components working groups and show how they evolved over time and become indispensable tools for teaching, training and learning in science, engineering and technology. We will demonstrate why, among all other described below, mobile laboratories constitute today the most appropriate to implement Massive Open Online Laboratories (MOOLs) or Mobile Open Online Laboratories (MOOLs) using a lab@home or portable laboratory concepts thanks to miniaturized open source electronic devices and cloud computing technologies.As member of research community networked distributed systems, we know that online labs, an instance of it, or commonly called labs at distance are distributed and flexible IT environments that enable a learner to perform laboratory work over computer networks, alone or in collaboration with other participants in a distance learning context. Participants are actors playing each one a role during an interactive session in synchronous or asynchronous mode through computer user interfaces. The online labs allow the sharing of material resources and expertise. They combine the advantages of different types of laboratories.

Abstract-Development of remote laboratories in academic settings has been held back because of the lack of standardization of technology, processes, operation and their integration with formal educational environments.Remote laboratories are used in educational settings for a variety of reasons, for instance, when the equipment is not available in the physical laboratory; when the physical laboratory space available is not sufficient to, either, set up the experiments or permit access to all on-site students in the course; or when the teacher needs to provide online laboratory experiences to students taking courses via distance education. Centers have been forming platforms that grant remote access to a collection of physical experiments that provide alternatives to educational institutions to reduce budgets of not only equipment purchases but also other expenses, such as, people, space, maintenance, and electricity consumption. This paper offers a taxonomy and examples of types of laboratories and hybrid combinations, and proposes UnifiedModeling Language (UML) models for remote laboratories incorporating access models for collaborative user roles in the educational context that support synchronous and asynchronous formats in learning environments. The need for development of adaptive interfaces for remote laboratories based on difficulty level and demonstrated user knowledge is presented. Finally, the paper proposes a scheme of virtualization of the infrastructure and an adaptive scheme of assisted remote laboratories where part of the experience is carried out by the user (student) and part is assisted by the system (teacher avatar) that is able to act as a team mate for the students during the experimentation process.

“…• Laboratory As A Service: the laboratory will be realized as an independent module, implemented as a set of web-services and with a high level of abstraction and virtualization [7]. The lab will be managed by means of a Remote Lab Management System (RLMS) able to interact with the University web-platform and with web-platform by means of a middleware.…”

Abstract-Remote laboratories are increasingly being used in academic courses, especially in science and engineering. New control systems allow the development of even complex experiments with a low cost. In this paper we present a remote laboratory that reproduces a small-scale photovoltaic system, including a solar panels and lights, a charge controller, a battery and a dummy load. A Raspberry PI microcontroller is used to send the different inputs to the laboratory, handling commands, measuring some electrical quantities and provide remote access via the web. The laboratory, developed with the involvement of graduating students, will be used in the Master courses of electrical engineering. Particular attention has been paid on the development of hardware and software, to use the developed laboratory as a model for the realization of other experiments.
