Motivation

Motivation

  • Creating virtual laboratory and a community of young learners, teachers and researchers to explore collaboratively the practical aspects of Engineering curriculum .

  • Significance and importance of laboratory work in E-Learning

  • Internet provides connectivity everywhere and broadband access enables high capacity connections.

  • Non – Availability of high-cost equipments in all universities.

  • Why not we Collaborate different universities in India and

    share the Laboratory resources for quality education.


Project objectives

Project Objectives

  • To implement online virtual & Remote laboratory for Engineering curriculum of Electronics, Control & Instrumentation Engineering.

  • To determine what set of fundamental concepts can be addressed in a laboratory environment for Engineering Curriculum

  • To parse each experiment undertaken into pieces that can be addressed

    • by simulation,

    • by Virtual lab using stored experimental data

    • by actual manipulation of equipment remotely.

  • To collaborate and share the laboratories of different universities.


The innovation statement

The Innovation Statement

  • Collaborating and cooperating universities by sharing lab resources will offer cooperative programs of studies.

  • Laboratory ware will be usable for many different groups of learners

  • Open universities studies can be integrated

Course and lab integration

Course and Lab Integration

Remote Lab

  • Hybrid Mode: Lecture in Class and experiment conducted on-line.

  • Each experiment can be conducted in three phases:

    • Simulation

    • Virtual lab using stored experimental data

    • Remote access & operation of real equipment

Physical Lab


Online laboratory teaching model

Online Laboratory Teaching Model

  • Custom built simulation package designed for virtual laboratory.

  • Remote experiment uses SCPI, Run time Active-X for each experiment with web services.

Time frame per laboratory

Time Frame per Laboratory

Procurement of equipments 2 weeks

ETB Design 2 weeks

ETB Development 4 weeks

Web Services Deployment 1 week

Testing and Validation1 week

Total10 weeks per Laboratory

For completing all the 10 labs the time frame requirement is 100 weeks in total. The project duration would be for 2 years.

Total Time Frame


Scope and use

Scope and Use

  • Students can remotely operate laboratories

  • Laboratory instruments can have multiple student users

  • Students can "design" their own experiments

  • High-cost instruments can be shared

  • Students can use resources efficiently

  • Virtual laboratories can become part of distance-learning curricula

  • Standardization of course/laboratory format

  • Enlarge the availability of teaching/ training material

  • Collaborating and sharing lab resources from

    different universities.
