- Adapting remote labs to learning scenarios: case studies using VISIR and RemotElectLabPublication . Fidalgo, André Vaz; Alves, Gustavo R.; Marques, Maria A.; Viegas, C.; Costa-Lobo, Cristina; Henandez-Jayo, Unai; Garcia-Zúbia, Javier; Gustavsson, IngvarRemote laboratories are an emergent technological and pedagogical tool at all education levels, and their widespread use is an important part of their own improvement and evolution. This paper describes several issues encountered on laboratorial classes, on higher education courses, when using remote laboratories based on PXI systems, either using the VISIR system or an alternate in-house solution. Three main issues are presented and explained, all reported by teachers, that gave support to students' use of remote laboratories. The first issue deals with the need to allow students to select the actual place where an ammeter is to be inserted on electric circuits, even incorrectly, therefore emulating real-world difficulties. The second one deals with problems with timing when several measurements are required at short intervals, as in the discharge cycle of a capacitor. In addition, the last issue deals with the use of a multimeter in dc mode when reading ac values, a use that collides with the lab settings. All scenarios are presented and discussed, including the solution found for each case. The conclusion derived from the described work is that the remote laboratories area is an expanding field, where practical use leads to improvement and evolution of the available solutions, requiring a strict cooperation and information-sharing between all actors, i.e., developers, teachers, and students.
- Addressing software impact in the design of remote laboratoriesPublication . Garcia-Zúbia, Javier; Orduña, Pablo; Lopez-de-Ipina, D.; Alves, Gustavo R.Remote Laboratories or WebLabs constitute a first-order didactic resource in engineering faculties. However, in many cases, they lack a proper software design, both in the client and server side, which degrades their quality and academic usefulness. This paper presents the main characteristics of a Remote Laboratory, analyzes the software technologies to implement the client and server sides in a WebLab, and correlates these technologies with the characteristics to facilitate the selection of a technology to implement a WebLab. The results obtained suggest the adoption of a Service Oriented Laboratory Architecture-based approach for the design of future Remote Laboratories so that client-agnostic Remote Laboratories and Remote Laboratory composition are enabled. The experience with the real Remote Laboratory, WebLab-Deusto, is also presented.
- Institutional factors governing the deployment of remote experiments: lessons from the rexnet projectPublication . Hine, Nick; Alves, Gustavo R.; Erbe, Heinz-H; Muller, Dieter; Alves, J. B. M.; Pereira, C.; Ferreira, José M.; Sucar, Enrique; Herrera, Oriel; Chiang, Luciano; Garcia-Zúbia, JavierRemote labs offer many unique advantages to students as they provide opportunities to access experiments and learning scenarios that would be otherwise unavailable. At the same time, however, these opportunities introduce real challenges to the institutions hosting the remote labs. This paper draws on the experiences of the REXNET project consortium to expose a number of these issues as a means of furthering the debate on the value of remote labs and the best practices in deploying them. The paper presents a brief outline of the various types of remote lab scenarios that might be deployed. It then describes the key human and technological actors that have an interest in or are intrinsic to a remote lab instance, with a description of the role of each actor and their interest. Some relationships between these various actors are then discussed with some factors that might influence those relationships. Finally some general issues are briefly described.
- IX International conference on Remote Engineering and Virtual instrumentation REV 2012Publication . Garcia-Zúbia, Javier; Alves, Gustavo R.THE ninth edition of the International Conference on Remote Engineering and Virtual Instrumentation (REV) [1] was held at the Faculty of Engineering of the University of Deusto, Bilbao (Spain), from the 4th to the 6th of July, 2012.

- A mobile robot platform for open learning based on serious games and remote laboratoriesPublication . Iturrate, Iñigo; Martín, Gustavo; Garcia-Zúbia, Javier; Angulo, Ignacio; Dziabenko, Olga; Orduña, Pablo; Alves, Gustavo R.; Fidalgo, André VazWithin the pedagogical community, Serious Games have arisen as a viable alternative to traditional course-based learning materials. Until now, they have been based strictly on software solutions. Meanwhile, research into Remote Laboratories has shown that they are a viable, low-cost solution for experimentation in an engineering context, providing uninterrupted access, low-maintenance requirements, and a heightened sense of reality when compared to simulations. This paper will propose a solution where both approaches are combined to deliver a Remote Laboratory-based Serious Game for use in engineering and school education. The platform for this system is the WebLab-Deusto Framework, already well-tested within the remote laboratory context, and based on open standards. The laboratory allows users to control a mobile robot in a labyrinth environment and take part in an interactive game where they must locate and correctly answer several questions, the subject of which can be adapted to educators' needs. It also integrates the Google Blockly graphical programming language, allowing students to learn basic programming and logic principles without needing to understand complex syntax.

- VISIR deployment in undergraduate engineering practicesPublication . Tawfik, Mohamed; Sancristobal, Elio; Martín, Sergio; Gil, Charo; Pesquera, Alberto; Losada, Pablo; Díaz, Gabriel; Peire, Juan; Castro, Manuel; Garcia-Zúbia, Javier; Hernandez, U.; Orduña, Pablo; Angulo, Ignacio; Costa-Lobo, Cristina; Marques, Maria A.; Viegas, C.; Alves, Gustavo R.Practical sessions are the backbone of qualification in engineering education. It leads to a better understanding and allows mastering scientific concepts and theories. The lack of the availability of practical sessions at many universities and institutions owing to the cost and the unavailability of instructors the most of the time caused a significant decline in experimentation in engineering education over the last decades. Recently, with the progress of computer-based learning, remote laboratories have been proven to be the best alternative to the traditional ones, regarding to its low cost and ubiquity. Some universities have already started to deploy remote labs in their practical sessions. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well.

Tawfik, Mohamed; Sancristobal, Elio; Martín, Sergio; Gil, Charo; Pesquera, Alberto; Losada, Pablo; Díaz, Gabriel; Peire, Juan; Castro, Manuel; Garcia-Zúbia, Javier; Hernandez, U.; Orduña, Pablo; Angulo, Ignacio; Costa-Lobo, Cristina; Marques, Maria A.; Viegas, C.; Alves, Gustavo R.It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote laboratories have tackled this issues providing online reusable and shared workbenches unconstrained by neither geographical nor time considerations. Thereby, they have extremely proliferated among universities and integrated into engineering curricula over the last decade. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well. In addition, the paper address the next challenges and future works carried out at several universities within the VISIR community.
