Publicación A Study of Strategies for Developing Online Laboratories(IEEE, 2021-12-01) Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Chacón Sombría, Jesús; Dormido Canto, SebastiánResearchers and teachers around the world have created newsoftware and hardware to develop, reuse, and deploy online laboratories (labs). However, due to the nature of labs, most of the available solutions depend greatly on where and how online labs can be used in the first place. Thus, there have been multiple design solutions and great technology combinations. In this study, we analyzed and studied the main obstacles in the online lab development and the alternatives of the technologies, means, methodologies, and approaches on creating online labs. The resulting analysis showed the advantages, disadvantages, and problems of each key component and attempted to explore the working combinations that ensure the usability, modularity, universality, accessibility, and reliability of online labs. In addition, we explored a general solution to take advantage of the benefits of the technologies involved in online labs and to fix or reduce the impacts of the arising problems when developing and deploying online labs.Publicación Open and Low-Cost Virtual and Remote Labs on Control Engineering(Institute of Electrical and Electronics Engineers, 2015-06-15) Sáenz Valiente, Jacobo; Chacón; Jesús; Torre Cubillo, Luis de la; Antonio Visioli; Dormido Canto, SebastiánThis paper presents an open course in the University Network of Interactive Laboratories, which offers several virtual and remote laboratories on automatic control, accessible to anyone. All the details on one of these labs (a two electric coupled drives system that allows performing control practices in a 2 × 2 MIMO system with industrial applications) and the activities that can be performed with it are given. We use a low-cost solution for developing the virtual and remote labs shared in this open course, based on the use of a free authoring tool Easy Java/Javascript Simulations (EJsS) for building the laboratories' user interfaces and a cheap development platform board (BeagleBone Black). The virtual and remote labs are deployed into a free Learning Management System (Moodle) Web environment that facilitates their management and maintenance.Publicación The photoelectric effect and study of the diffraction of light: Two new experiments in UNILabs virtual and remote laboratories network(Società Italiana di Fisica, 2016-02-12) Sánchez Fernández, Juan Pedro; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Carreras, Carmen; Yuste, Manuel; Heradio Gil, Rubén; Dormido Canto, SebastiánThis work describes two experiments: “study of the diffraction of light: Fraunhofer approximation” and “the photoelectric effect”. Both of them count with a virtual, simulated, version of the experiment as well as with a real one which can be operated remotely. The two previous virtual and remote labs (built using Easy Java(script) Simulations) are integrated in UNILabs, a network of online interactive laboratories based on the free Learning Management System Moodle. In this web environment, students can find not only the virtual and remote labs but also manuals with related theory, the user interface description for each application, and so on.Publicación Design of a low-cost air levitation system for teaching control engineering(MDPI, 2017-10-12) Chacón, Jesús; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Díaz Martínez, José Manuel; Esquembre, Francisco; MDPIAir levitation is the process by which an object is lifted without mechanical support in a stable position, by providing an upward force that counteracts the gravitational force exerted on the object. This work presents a low-cost lab implementation of an air levitation system, based on open solutions. The rapid dynamics makes it especially suitable for a control remote lab. Due to the system’s nature, the design can be optimized and, with some precision trade-off, kept affordable both in cost and construction effort. It was designed to be easily adopted to be used as both a remote lab and as a hands-on lab.Publicación Self-organized laboratories for smart campus(IEEE (Institute of Electrical and Electronic Engineers), 2019-09-10) Huertas Celdrán, Alberto; García Clemente, Félix J.; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Salzmann, Christophe; Gillet, DenisA smart campus provides students who are geographically scattered with online tools to get access to learning resources and laboratories. Although these remote laboratories have the potential and capabilities to implement different learning experiments, most of them are configured in a static fashion, being able to serve only one experiment for a given period of time. This lack of adaptability and flexibility causes long waiting queues of students in certain overloaded remote laboratories, while others are underused. To overcome this limitation, a smart campus can incorporate new techniques and paradigms such as Network function virtualization (NFV) and Software-defined networking (SDN), which are rapidly modifying current cloud services and applications to provide autonomous and adaptive solutions. In this context, the main contribution of this paper is an SDN/NFV-based architecture with autonomic capabilities to adapt to the remote laboratories configuration according to the end-user demand. The proposed architecture will be able to optimize computing resources to ensure the users' quality of service in a smart campus with remote laboratories. A use case with a remote laboratory, based on the control of a servo motor, shows how our solution can dynamically change the lab service under specific circumstances. Finally, experiments using diverse configurations and service descriptions show the performance and suitability of the proposal.Publicación Open-source hardware in education: A systematic mapping study(IEEE Xplore, 2018-11-16) Heradio Gil, Rubén; Chacón, Jesús; Vargas, Héctor; Galán, Daniel; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de laThe open-source hardware movement is becoming increasingly popular due to the emergence of successful low-cost technologies, such as Arduino and Raspberry Pi, and thanks to the community of makers that actively share their creations to be freely studied, modified, and re-distributed. Numerous authors have proposed distinct ways to seize this approach for accomplishing a variety of learning goals: enabling scholars to explore scientific concepts, promoting students’ creativity, helping them to be more fluent and expressive with new technologies, and so on. This paper reports a systematic mapping study that overviews the literature on open-source hardware in education by analyzing and classifying 676 publications. The results of our work provide: 1) guidance on the published material (identifying the most relevant papers, publication sources, institutions, and countries); 2) information about the pedagogical uses of open-source hardware (showing its main educational goals, stages, and topics where it is principally applied); and 3) directions for future research.Publicación Taller y laboratorio: Cuerda vibrante, un nuevo laboratorio virtual y remoto para Técnicas Experimentales II(Universidad Nacional de Educación a Distancia (España).
