Professor Lawrence Kunle Kehinde, a former Departmental chair, Engineering dean and University Deputy vice chancellor, received his B.Sc. 1st class Honors in Electronics in 1971, and a Control Engineering in 1975, at the University of Sussex UK. As a fellow of the international Atomic Energy Agency; He had his postdoctoral studies in Nuclear Instrumentation at the University of California, Berkeley from 1977 to 1978. He has spent most of his years as a professor of Instrumentation Engineering at the Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. He was the rector of the first private Polytechnic in Nigeria. He recently concluded a three-year visiting professor term at the Texas Southern University, Houston Texas. He has worked in Techno-Managerial position as the director of ICT at OAU for years. His major field is Instrumentation Designs and has designed equipment. He was the founding principal investigator of the University’s iLab research and he currently designs remote and virtual experiments for remote experimentation. He is a chartered engineer, a fellow of both the Computer Association of Nigeria, and Computer Professionals of Nigeria and a member of IEEE and ASEE. He has over 75 publications in Journals and Proceedings. He also jointly has two British Patents in the past.

Development of a Remote Operational Amplifier iLab Using Android-based Mobile PlatformiLabs are experimental setups that can be remotely accessed through the Internet using a webbrowser. They allow students and educators to carry out experiments from remote locationsanywhere and at any time. Globally, more than a dozen iLabs have been developed anddeployed. However they all collectively suffer from an increasingly important oversight: theirinterfaces are developed for desktops and laptop computers. This is considered an oversightbecause there is substantial evidence that mobile devices, by virtue of their extremely rapid rateof increase in usage as well as portability, are emerging as the form factor of choice in the nearfuture.This paper describes a completely functional Android-based mobile Operational Amplifier iLabthat will enable students all over the world perform experiments remotely from a mobile deviceusing the Android platform. There are already other mobile platforms on the market today.However, Android is an environment that combines an open, free development platform basedon Linux and gives good access to hardware. Android allows users to explore the mobile Internetafresh with its new features, easy access to the Internet, ease of development, new services andapplication. This makes it easy for a user/client to interact with the iLabs service broker andperform experiments. Android’s openness and flexibility makes it a deciding factor over theclosed iPhone framework that provides a similar set of features. This work serves as animprovement to the earlier research and work done especially by the authors in the area ofmobile laboratories under iLab.Using appropriate measures, authors will use questionnaires to study the influence of the mobileplatform over the existing laptops client interfaces on ergonomics, students’ understanding of thelabs and the promptness of returns of lab reports.
