1. Introduction
Robots and robotic technologies have an intellectual and emotional appeal that transcends
any other type of engineered product, and this appeal is felt no more so than with children
and young adults. Robots and robotic technologies represent a practical application of
physics, computer science, engineering, and mathematics, and provide a very powerful and
flexible approach to demonstrate a variety of engineering concepts. In addition, robotics
appeals to a broad range of interests and allows multiple points of access to science,
mathematics, and engineering for many types of learners. As a result, robotic technology
and robots are being used by an increasing number of educators at the college level to
reinforce computer science and engineering theory, and to teach basic software and
mechanical engineering at the grammar school, middle school and high school levels. The
giant strides that we have made in the areas of Communications and Computers are
possible only because of the great successes that we have achieved in the field of
Electronics.
It is sometimes unbelievable, how many electronics gadgets that we carry these days in our
person –Digital Wrist-watch, Calculator, Cell-phone, Digital Diary or a PDA, Digital Camera
or a Video camera, etc. The different type of Electronic equipments that has invaded our
offices and homes these days is also mind boggling. Many things we use at home and office
are “remote controlled”, for example, Television (TV), Air-Conditioners, Audio equipment,
Telephone, etc. It is almost close to “magic” how even a child, now-a-days, can switch
channels, or increase decrease the volume of sound in a TV at home by just clicking on a
few buttons sitting at the comfort of a sofa away from the Television apparently without
any physical wiring or connection!
Again, we are astonished, how we are able to talk to our near and dear living several
thousands of Kilometers away, from wherever we are, at home, office, on the road in a car,
or in a classroom –by just clicking a few n umbers on our palm sized cellular phones!
Electronics has made deep impact in several vital areas such as health care, medical
diagnosis and Treatment, Air and space travels, Automobiles, etc. In short, the technological
developments of several countries of the globe are directly related to their strengths in
electronics design, manufacture, products and services. Just as we teach physics, chemistry,
biology and mathematics in our schools, it is high time we start teaching our children at
school, Electronics as a separate subject by itself. This brings us face to face to an important
question: How to teach the basic concepts of such an important subject like Electronics
most effectively? If one wants to gain a good understanding of electronics, he or she should
build circuits and test them independently. For this one should acquire a practical
knowledge of the characteristics of different devices and in constructing the various circuits.
Let us try to learn such skills by the proven scheme of “LEARNING BY DOING”. There is only
one way to learn to do anything: and I found Robotics is the best way to learn all this.
So let’s start doing Robotics!!!
