Internet-enabled technologies for robotics education are gaining importance as online platforms promoting skill training.  Understanding the use and design of robotics are now introduced at university undergraduate levels, but in developing economies establishing usable hardware and software platforms face several challenges like cost, equipment etc. Remote labs help providing alternatives to some of the challenges. We developed an online laboratory for bioinspired robotics using a low-cost 6 degree-of-freedom robotic articulator with a neuro-inspired controller. Cerebellum-inspired neural network algorithm approximates forward and inverse kinematics for movement coordination. With over 210000 registered users, the remote lab has been perceived as an interactive online learning tool and a practice platform. Direct feedback from 60 students and 100 university teachers indicated that the remote laboratory motivated self-organized learning and was useful as teaching material to aid robotics skill education.

Lab work and exercises are an essential part of Electronic Engineering Education as it improves understanding of the theoretical concepts. Remote Labs like VISIR (Virtual Instrument Systems in Reality) can supplement the learning process but are limited to a small set of components. Therefore, experiments with VISIR should be combined with prepared and fixed circuits.<br />This work presents an approach, where in the first step new exercises are de-veloped with the NI ELVIS platform, and later implemented with the much more cost-effective NI myDAQ platform. In general, the entire system is very inexpen-sive and scaleable, since a single PC can act as a host for a wide number of exer-cise boards, each of which is connected via a myDAQ.

<p class="Abstract">The goal of this paper is to introduce <em>open </em>modular <em>hardware </em>and <em>software </em>system “iSES Remote Lab SDK” (iSES – internet School Experimental Studio) designed for easy creation of real remotely controlled laboratories (RCL) that are accessible from PC, tablets and mobile phones. Open modular system “iSES Remote Lab SDK” consists of approx. 20 freely distributable JavaScript objects in a commented source code. Widgets are highly configurable and provide many well documented options and allow to build a complex measurement and control interface with data and video transfer. Open modular system “iSES Remote Lab SDK” can communicate with different measurement platforms (ISES, Arduino are ready; CMA CoachLab, Vernier etc. are tested), and also common universal measurement devices with a COM or USB port, further universal rotation and linear motion stepper motors, etc.). We will introdukce our 18 online advanced remote labs. Any user may have an access to the RCL on PC and mobile devices (iPad, smart phone, etc.) as well. Even non-programmers can build up a simple RCL and publish it in 15 minutes on the Internet!  System “iSES Remote Lab SDK“ has obtained the GOLC Online Laboratory Award 2016 in the category Remote Controlled Lab [1].</p>

In this paper, a novel simple robotic system is developed for surgical training in minimally invasive surgery (MIS). The robot automatically measures motion data of instruments in real time using internal encoders, without additional sensing mechanisms. Kinematics equations are integrated in the control software to map motor motion to the instrument tip motion. These recorded motion data then can be analyzed in the computer system for objective evaluation using well established criteria. A neural network algorithm is employed in real time as the observer of weight and inertia effects which are compensated through motor control. Experiment results show that this compact robot provides good stability and smooth motion while guiding instruments using surgeon input. The tracking resolution is sufficient for objective evaluation purposes. The robot combines the realistic feel of MIS instruments with the capability of the computer to tabulate objective measures of performance and skill. Its flexibility as a training instrument can be of great benefit in both providing surgeons with much-needed practice and assessing the outcomes of that practice.

<p class="0abstract">The physical training education systems of the faculties of science focus on practical manipulations. Remote Labs are a recent approach used for educating experimental manipulations by using the performance of information and communication technologies. This article presents a real remote laboratory using low-cost embedded systems addressed to engineering and undergraduate students. The manipulation is based on the electronic control system to change the temperature with a plate-form, which is developed to permit students and teacher access to this manipulation. Our purpose of this study is the development of a control system to improve current educational systems in Moroccan universities by managing practical manipulations for a large number of students, based on a web from anywhere and anytime. Measuring and Monitoring of Temperature changes is a new experience of a remote monitoring system that will be allowed the users to access the experiment thought a specific web site.</p>

Abstract Finance is vital for the green energy transition, but the access to low cost finance is uneven as the cost of capital differs substantially between regions. This study shows how modelled decarbonisation pathways of developing economies are disproportionately impacted by assumptions around their cost of capital (WACC). For example, representing regionally specific WACC values indicates 35% lower green electricity production in Africa for a cost-optimal 2°C pathway. Moreover, results show that early convergence of WACC values for green and brown technologies in 2050 would allow Africa to reach net-zero emissions approximately 10 years earlier than when convergence is not considered. A “climate investment trap” arises for developing economies when climate-related investments remain chronically insufficient. Elements of sustainable finance frameworks currently present barriers to these finance flows and radical changes are needed so that capital is better allocated to the regions that most need it.

Background. Over the last few decades, in developing nations including India, there have been rapid developments in information and communication technologies with progress towards sustainable development goals facilitating universal access to education. With the aim of augmenting laboratory skill training, India’s Ministry of Human Resource Development (MHRD)’s National Mission on Education through Information and Communication Technology (NME-ICT), launched Virtual laboratories project, enabling professors and institutions to deliver interactive animations, mathematical simulators and remotely-controlled equipment for online experiments in biosciences and engineering courses. Towards that mission of improving teaching and learning quality and with a focus on improving access to users in geographically remote and economically constrained institutes in India, we developed and deployed over 30 web-based laboratories consisting of over 360 computer-based online experiments. This paper focuses on the design, development, deployment of virtual laboratories and assesses the role of online experiments in providing self-learning and novel pedagogical practices for user communities. Methods. As part of deployment, we evaluated the role virtual laboratories in facilitating self-organized learning and usage perception as a teaching tool in a blended education system. Direct feedback data was collected through organized workshops from 386 university-level students, 192 final year higher secondary school (pre-university) students and 234 college professors from various places across India. We also included online feedback from 2012-2018 to interpret usage analysis and adaptability of virtual and remote labs by online users. Results. More than 80% of students who used virtual laboratories scored higher in examinations compared to a control group. With 386 students, 80% suggested adapted to self-learning using virtual laboratories. 82% of university teachers who employ virtual laboratories indicated using them to complement teaching material and reduce teaching time. Increase in online usage and feedback suggests novel trends in incorporating online platforms as pedagogical tools. Discussion. Feedback indicated virtual laboratories altered and enhanced student’s autonomous learning abilities and improved interaction in blended classrooms. Pedagogical analysis suggests the use of ICT-enabled virtual laboratories as a self-organized distance education learning platform for university and pre-university students from economically challenged or time-restrained environments. Online usage statistics indicated steady increase of new users on this online repository suggesting global acceptance of virtual laboratories as a complementing laboratory skill-training online repository.

The case describes the evolution between 1999 and 2008 of a family-owned contract manufacturing company into a publicly traded, US$400 million global firm. The son of the founder, Bernie Auyung, assumed the CEO position with the company during this period and has worked with his father to build a broader, professional management team. In the process the company has applied a range of leading-edge innovation management and strategy tools that put it far ahead of most Chinese peer companies. Computime provides an exceptional model for other companies in developing countries looking to evolve from a low-cost competitor into a global leading company with its own technologies and brands. Students are asked to assume Bernie's role and suggest the path forward. The teaching note describes what the team actually did, and addresses the questions raised at the end of the case.Computime provides an exceptional example of how to evolve from an entrepreneur-led startup competing on low cost and the vision of the founder to a global, professionally managed company listed on a major exchange (the Hong Kong Stock Exchange in this case). Students are also able to explore a company in the process of instituting many of the leading innovation management tools described in classes focused on innovation management. The case would also be quite valuable for classes focused on the challenges facing family enterprises that must evolve beyond the control of a visionary founder. It resonates particularly well with students in developing economies both in Asia and beyond.

Current efforts to achieve neuromorphic computation are focused on highly organized architectures, such as integrated circuits and regular arrays of memristors, which lack the complex interconnectivity of the brain and so are unable to exhibit brain-like dynamics. New architectures are required, both to emulate the complexity of the brain and to achieve critical dynamics and consequent maximal computational performance. We show here that electrical signals from self-organized networks of nanoparticles exhibit brain-like spatiotemporal correlations and criticality when fabricated at a percolating phase transition. Specifically, the sizes and durations of avalanches of switching events are power law distributed, and the power law exponents satisfy rigorous criteria for criticality. These signals are therefore qualitatively and quantitatively similar to those measured in the cortex. Our self-organized networks provide a low-cost platform for computational approaches that rely on spatiotemporal correlations, such as reservoir computing, and are an important step toward creating neuromorphic device architectures.
