Design and implementation of a Framework for remote experiments in education

Remote Controlled laboratories is a teaching and learning tool that increasingly becomes fundamental in the teaching and learning processes at all the levels. A study of available systems highlights a series of limitations on the used programming languages, overall architecture and network communication patterns that, that hinder these systems to be further adopted. Current technologies and modern WEB architectures allow the resolution of such limitations. Here we present the FREE (Framework for Remote Experiments in Education) platform, a novel system, that, using modern technologies, architectures, and programming practices, will be easier to integrate with external tool and services and new experiments. FREE was developed in Python, Django programming framework, HTML, JavaScript, and web services to easy the development of new functionalities. The designed architecture provides a louse coupling between the infrastructure and the remote experiments facilitating further developments and allow new experiment integrations. Currently FREE is already running in various countries providing access to about five types of experiments in the area of physics), integration with various Learning Management Systems and external Authentication mechanisms. Using FREE the development and integration of new experiments (independently of the supporting Hardware and programming language) is now easier to be made available to remote users.Comment: Accepted for publication and presentation on 2022 VIII International Engineering, Science and Technology Conference, Panama City, October 19-21, 202

Cloud Based Remote FPGA Lab Platform: An Application of Internet of Things

IoT (Internet of Things) is the next generation of the Internet. The main goal of IoT is to connect each and every physical object to the Internet Cloud. This concept is introduced by bringing IoT technology to the laboratories, making expensive laboratory equipment available on-cloud for real-time experimentation. In this paper, an on CLP (Cloud Laboratory Platform) is presented by employing the concept of IoT to the academic experimentation environment. The CLP allows a rapid deployment of an online laboratory system enabling students and researchers to perform actual experiments on the on-Cloud laboratory equipment using a web interface. A web interface for end users to access front end of the system. This interface was developed for login purposes so that any user can perform experiments from anywhere. The interface also provides options for comments and feedback. Moreover, this research contribution also facilitate users to test their designs and record observations in real-time on the equipment. For demonstration purposes, a remote lab has been developed for high-tech Xilinx FPGA (Field Programmable Gate Array) development boards, namely Spartan-II and Spartan-III. This project aims to provide students a new tool to enhance their learning experience and encourage them to test their theoretical knowledge in practical applications

IP Based Module for Building Automation System

Embedded systems technology has a lot of applications in the various fields of life to bring ease and comfort for humans. One kind of applications is in the development of modern buildings, where embedded systems are applied to the control system. Building Automation Systems (BAS) are often encountered in modern buildings today. They are responsible to automatically control the building appliances such as electrical equipments, fire alarms, security systems, and others. Conventionally, a smart home that can be controlled by an embedded system is connected to a central monitoring unit such as a computer. The system commonly employs RS232 or RS485 serial communication, so that the control activities cannot be carried out from a long distance. With the rapid technology development in the field of communication, many recent communication devices are practical and have a good performance. One of them is a device with the Android operating system that can access the internet, thus it has a significant role in simplifying the management of smart homes. This research proposes the design of a smart home that can conserve energy by turning off unneeded electrical appliances, detect disorders such as flood, fire, and theft, and also serve as an early warning system through SMS Gateway. It can be monitored and controlled remotely over the Internet by an Android device

Virtual laboratories for education in science, technology, and engineering: A review

Within education, concepts such as distance learning, and open universities, are now becoming more widely used for teaching and learning. However, due to the nature of the subject domain, the teaching of Science, Technology, and Engineering are still relatively behind when using new technological approaches (particularly for online distance learning). The reason for this discrepancy lies in the fact that these fields often require laboratory exercises to provide effective skill acquisition and hands-on experience. Often it is difficult to make these laboratories accessible for online access. Either the real lab needs to be enabled for remote access or it needs to be replicated as a fully software-based virtual lab. We argue for the latter concept since it offers some advantages over remotely controlled real labs, which will be elaborated further in this paper. We are now seeing new emerging technologies that can overcome some of the potential difficulties in this area. These include: computer graphics, augmented reality, computational dynamics, and virtual worlds. This paper summarizes the state of the art in virtual laboratories and virtual worlds in the fields of science, technology, and engineering. The main research activity in these fields is discussed but special emphasis is put on the field of robotics due to the maturity of this area within the virtual-education community. This is not a coincidence; starting from its widely multidisciplinary character, robotics is a perfect example where all the other fields of engineering and physics can contribute. Thus, the use of virtual labs for other scientific and non-robotic engineering uses can be seen to share many of the same learning processes. This can include supporting the introduction of new concepts as part of learning about science and technology, and introducing more general engineering knowledge, through to supporting more constructive (and collaborative) education and training activities in a more complex engineering topic such as robotics. The objective of this paper is to outline this problem space in more detail and to create a valuable source of information that can help to define the starting position for future research
