research and development, most remotely-accessiblelaboratories have remained as isolated technical novelties, with most projects being shutdownonce their initial funding runs out. This point is reflected in the fact that most works in theliterature address only the technical merits and potential benefits of remote access technologies, Page 14.1209.2rather than addressing the impact of remote experimentation on engineering pedagogy. Clearly, anew fundamentally different approach to remotely-accessible laboratories is required.Recently, a new paradigm for remotely-accessible laboratories, namely the eLaboratory, wasintroduced by the authors5. This
for thestepped tube, and reflection/extension. This section describes what the students are asked to doas the exercise proceeds. The entire worksheet is included as Appendix 1.To determine an equation to use for the pressure transducer the students are given two datapoints and told that the transducer is linear over its’ useful range. On the surface it is a simpletask to determine the equation of the straight line describing the calibration curve, and thestudents do manage to complete this task. However, observations during the lab exercise exposethat many students do not really understand the concept of transducer calibration and strugglewith this. While some students manage this task quite easily, others need guidance to get themgoing in
experiments.III. Basis for Developing ADLabThe digital electronics aspect of the present electronic and electrical engineering curriculumat Obafemi Awolowo University has been deficient for some time. The curriculum has notbeen reviewed in close to a decade and it does not reflect the rapid changes that have beenwitnessed in high chip-count digital electronic in the last two decades. Specifically, although Page 14.163.4the design of application specific ICs are treated under the microelectronics aspect of thecurriculum, programmable logic devices are not (figure 2 shows the spectrum of digitalelectronic devices). In the laboratory however, there are
goals of this project were to utilize laptops already required of students to improve theirlearning experience in a microcontroller applications course and to reduce the per seat coursedelivery cost. Using laptops in conjunction with the Microchip PICKit1 did improve the studentlearning experience as reflected in the course grade and course evaluation written comments. Perseat costs of this approach were approximately half the cost of maintaining a dedicatedmicrocontroller lab. Written and verbal comments from students using the PICKit1 developmentkit indicated that they enjoyed having the freedom to work on their microcontroller projects atany time. Follow up anecdotal evidence also indicated that the flexibility and portability of
working with RapidWorks/ SolidWorks were expected to create a back plate for themodel in the SolidWorks. Each team was given separate instructions of how to use theequipment and software. A detailed manual for E-Scan, SLIM and LeiosMesh was alreadyavailable. However, though there is a manual available for NextEngine scanner, no writteninstruction for using RapidWorks software exists. A short list of instructions specifically orientedto complete this project was being developed at that time which has not yet been field tested.This fact was reflected in negative feedback from students at the end of the semester who had touse the NextEngine/RapidWorks system. One of the students in the class was trained in thissystem at the beginning of the semester
summarize the results from design verification testing. It should indicate whether all the requirements were met. If any requirements could not be met, they should be listed in this section. The students should refer to the RSLogix500 project report.≠ Conclusions – The conclusions section should also summarize what students learned by executing the project and should identify problems encountered other than equipment problems during the lab session.≠ References – The references should be any resources relevant to the assigned lab topics.≠ RSLogix500 Project Report – The RSLogix500 report should reflect the following options in the configuration and ladder options dialog: Figure 8.

. Students clearly enjoyed this achievement. The governing equation for the steel ball in Page 14.839.5equilibrium is derived from Newton’s Second Law where magnetic force and weight act inopposite directions. The magnetic force is modeled as proportional to current squared divided bygap distance squared: ⎛ i2 ⎞ m&x& + c⎜⎜ 2 ⎟⎟ − mg = 0 ⎝x ⎠where m is the steel ball mass, x is the air gap between steel ball and electromagnet, &x& is theacceleration, c is a proportionality constant reflecting the
