FPGA remote laboratory: experience of a shared laboratory between UPNA and UNIFESP

Abstract: For teaching hardware design, FPGAs are a powerful technology, where students can learn how to design hardware using common hardware description languages such as VHDL or Verilog. However, the use of FPGAs in the classroom has several different problems, such as availability or associated costs of acquiring and maintaining the FPGAs, and relying on FPGA boards in the classroom is typically problematic because students cannot use the boards for doing projects after classes or during weekends. To solve this problem, remote laboratories can help allowing more flexibility to students. A remote laboratory is a hardware and software system that allows students to access a real FPGA located somewhere else on the Internet. In this article, a cross-national remote laboratory is presented. This remote laboratory has multiple copies (17 devices at the time of this writing) deployed both in UPNA (Spain) and UNIFESP (Brazil), and using EdTech LabsLand (Spain) for technology and management of the laboratory. Students of both institutions access transparently these laboratories, providing automatic fault tolerance and increasing the number of concurrent students using the laboratories by sharing the boards among both institutions **Thanks to the financial contribution made by UPNA and UNIFESP Universities for the acquisition of the necessary material for the development of the laboratories and the donation of the Terasic DE1-SoC kits made by Intel.

This provides automatic fault tolerance and increases the potential number of concurrent students using the laboratories by sharing the boards among both institutions.

Analog Electronic Experiments in Ultra-Concurrent Laboratory

Abstract: Conventionally in the classrooms, concepts related to Electronic courses like Electronic circuits will be conveyed by writing circuit diagram, deriving the design equations & showing the waveforms. Sometimes simulations are also used for the purpose in the classroom. However, most of the times students will not be convinced by this pedagogical approach as they have not seen the real time implementation of the circuit and real time typical values of the experiment. Therefore students can’t connect to the concepts and they fail to analyze the circuit and hence the learning become incomplete. In this paper an innovative approach towards experiential learning is introduced for Analog electronic circuits.

A Federation of Remote Laboratory OERs: Grid of VISIR systems through PILAR Project

Abstract: Today's educational needs require tools with neither geographical nor temporal restrictions. These tools also have to help students to reach the knowledge and provide them with the skills that the labor market demands. To achieve this goal, the technical areas rely on the contribution that laboratory practices provide. However, traditional laboratory practices, carried out in person at the institution, are limited due to the requirements of both their exploitation and their provision. For this reason, educational institutions have opted for remote laboratories (RLs) as the educational tool to provide the benefits of experimentation in real environments, either as an accompaniment to face-to-face activity or as the only mean of experimentation in real environments. Although RLs provide exclusive benefits >, they also present limitations derived from the technology involved >; PILAR project > was conceived under this premise. PILAR proposes a federation of 5 Virtual Instrument Systems in Reality (VISIR) systems. VISIR is a RL for wiring and measuring electrical and electronics circuits in a simulated workbench. PILAR aims to create a grid of laboratories shared and accessed by all participants, expanding and empowering the existing systems to a new level of service and capacity.

Using VISIR Remote Lab in the Classroom: Case of Study of the University of Deusto 2009–2019

Abstract: During the last ten years, the University of Deusto is using VISIR remote lab for analog electronics in the Faculty of Engineering. Present paper shows how we are using the VISIR with students, and its results. It is a catalog of experiments to invite other universities to join the VISIR consortium. Ongoing and future research in VISIR are also presented.

Experience with the VISIR Remote Laboratory at the Universidad Estatal a Distancia (UNED)

Abstract: The Universidad Estatal a Distancia (UNED) in Costa Rica is the public distance-education university in Costa Rica. It has been regularly using different types of remote laboratories since 2017, and is in the process of deploying new remote laboratories, as well as providing high quality simulations for improving the experimentation process in distance education; in the particular fields of Physics and Engineering. LabsLand is the global network of educational real laboratories available online. In 2018, UNED and LabsLand deployed the VISIR electronics remote laboratory in UNED. Since then, at the time of this writing, 167 students have had 979 laboratory sessions, including both in class and in multiple workshops with school teachers and international events with other researchers and professors.

Mobile Arduino Robot Programming Using a Remote Laboratory in UNAD: Pedagogic and Technical Aspects

Abstract: The National Open and Distance University - UNAD, is an autonomous university entity of the national order, with special regime It has 8 zones and 64 education centers By using the first remote mobile robotics laboratory based on the Arduino platform and incorporating the LabsLand Arduino Robot, an alternative that in addition to reducing costs allows coverage for students who are located in distant areas and who have difficulty accessing laboratory practices It is planned to replace the use of simulators or loose microcontrollers, without any robotic structure, by incorporating this new technological tool The educational approach it is due to the need to incorporate “e-learning” activities and laboratory practices in the course of microprocessors and microcontrollers during the month of October and the first week of November and measure the technological and pedagogical impact on open and distance education For this purpose, 110 students participated and from those, 78 students conducted the survey subsequently the results evaluated in the activities are compared with the rest of the students who carry out traditional activities and a matrix of indicators is obtained, that allows measuring the educational impact on the use of technological tools compared to traditional laboratory activities and practices in the course of microprocessors and microcontrollers
