Excerpts from interaction session of Editorial committee with Dr U Chandrasekhar, Additional Director, GTRE Bengaluru. The interaction was based on “Research- A Career opportunity for Young Engineers”. Ed: Where can a young aspirant look to build his/her Research Career? Dr UC: Research as the career option is available for engineers at various organizations like ISRO, DRDO, CSIR labs, BARC etc and also with many global players like GE, GM, Bosch, Daimler Chrysler etc., have setting up their R&D centers in India, the research options are on a growth path. So the numbers are continuously growing for Indian engineers. Ed: Can you list few major research projects presently being carried out in India. Dr UC: India is home for many major research works, to list I can say,
• Satellite based communication and navigation systems for rural connectivity, security needs and mobile services.
• Development of Heavy lift launcher • Reusable Launch Vehicles - Technology demonstrator missions leading to Two Stage
To Orbit (TSTO) • Human Space Flight • Chandrayaan-2
Ed: Large number of students community doesn’t see Research as a career. What do you like to say to them? Dr UC: Currently many engineers have started looking at R&D as a very important option. Many engineers from IITs are also joining. One example is recently department of space conducted entrance examination for their BE program (Trivandrum - IIST) and I understand lakhs of students wrote this examination. Ed: Freshers say “We don't find the growth in Research so fascinating as we get to
experience in a Private or a MNC firm" Dr UC:This thinking is no longer valid - it has changed with global careers in R&D Ed:Students in campus/ fresher feel "pace of work at Research" is a factor of concern for
them to choose this field. Dr UC: Pace of work, excitement, sense of achievement in R&D labs are also very prominent. Ed:What qualities should an engineer possess to build his/her career in the field of Research? Dr UC: Passion for research and commitment to cause. Ed: Piece of advice to students. Dr UC: If you are serious about R&D, please derive inspiration from great sons of soil like Dr. APJ Abdul Kalam, Dr, Vikram Sarabhai, Dr. Homi Bhabha, Dr. C V Raman, and you can enable world-class achievements that can impact the lives of the people from all walks of life.

NANO ROBOMEDICINE
“A pessimist sees the difficulty in every opportunity;
An optimist sees the opportunity in every difficulty.”
Winston Churchill, (1874-1965)
Nobel physicist Richard P Feynman, in the year of 1959, in his remarkably prescient talk, was clearly aware of the potential medical applications of the new technology and proposed employing machine tools to make smaller machine tools, these to be used in turn to make still smaller machine tools, and so on all the way down to the atomic level. In connection with biological cells, he said “that we can manufacture an object that maneuvers at that level” Albert R.Hibbs, a mathematician of Jet Propulsion Laboratory NASA, suggests a very interesting possibility for relatively small machines. He said that, although it is a very wild idea, it would be interesting in surgery if you could swallow the surgeon. You put the mechanical surgeon inside the blood vessel and it goes into the heart and looks around (of course the information has to be fed out.). It finds out which valve is the faulty one and takes a little knife and slices it out. Other small machines might be permanently incorporated in the body to assist some inadequately functioning organ. The vision behind Feynman’s remarks became a serious area of inquiry two decades later, when K.Eric Drexler, while still a graduate student at the Massachusetts Institute of Technology, published a technical paper suggesting that it might be possible to construct a nano‐devices from biological parts, that could inspect the cells of a living human being and carry on repairs within them. Nano‐robotics is the emerging technology field of creating machines or robots whose components are close to the microscopic scale of a nanometer (10−9 meters). Due to the advances in the field of nanotechnology, nano‐device manufacturing has been growing gradually. With the expected miniaturization of devices provided by several works on nanoelectromechanical systems (NEMS), nanomanufacturing has actually become a reality for the ongoing developments of molecular‐scale electronics, sensors and motors are expected to
enable microscopic robots with dimensions comparable to bacteria. The artificial mechanical red blood cell or “respirocyte” is a bloodborne spherical 1‐micron diamondoid 1000‐atmosphere pressure vessel with active pumping powered by endogenous serum glucose. It is able to deliver 236 times more oxygen to the tissues per unit volume than natural red cells and to manage carbonic acidity. An artificial mechanical white cell of microscopic size, called a “microbivore,” has as its primary function to destroy microbiological pathogens found in the human bloodstream using a digest and discharge protocol.
Nanomedicine is the process of diagnosing, treating, preventing disease and improving human health, using molecular tools and molecular knowledge of the human body. Biotechnology will make possible even more remarkable advances in molecular medicine and biobotics, including microbiological biorobots or engineered organisms. Perhaps 10–20 years from today, the earliest molecular machine systems and nanorobots may join the medical armamentarium, finally giving physicians the most potent tools imaginable to conquer human disease, ill‐health, and aging. In the first half of the 21st century, nanomedicine should eliminate virtually all common diseases of the 20th century, and virtually all medical pain and suffering as well.

GREEN ENGINE GLOBAL ISSUES Everyday radios, newspapers, televisions and the internet warn us of energy exhaustion, atmospheric pollution and hostile climatic conditions. After few hundred years of industrial development, we are facing these global problems while at the same time we maintain a high standard of living. The most important problem we are faced with is whether we should continue developing or die. Statistics show that, the daily consumption of petroleum all over the world today is 40 million barrels, of which about 50 percent is for automobile use. In accordance with this calculation, daily consumption of petroleum by automobiles all over the world is over two million tonnes. At the same time as these fuels are burnt, poisonous materials such as 500 million tonnes of carbon monoxides (CO), 100 million tonnes of hydrocarbons (HC), 550 million tonnes of carbon ©, 50 million tonnes of nitrogen oxides (NOx) are emitted into the atmosphere every year, severely polluting the atmosphere. Addressing such problems is what a Green engine does or tries to do. The Green engine as it is named for the time being is a six phase engine, which has a very low exhaust emission, higher efficiency, low vibrations etc. Apart from these features, is its uniqueness to adapt to any fuel which is also well burnt. Needless to say, if implemented will serve the purpose to a large extent. TECHNICAL FEATURES Compared to conventional piston engines, operated on four phases, the Green engine is an actual six phase internal combustion engine with much higher expansion ratio. Thus it has six independent or separate working processes: intake, compression, mixing, combustion, power and exhaust, resulting in the high air charge rate. The most important characteristic is the expansion ratio being much bigger than the compression ratio. Direct Air Intake Direct air intake means that there is no air inlet pipe, throttle and inlet valves on the air intake system. Air filter is directly connected to the intake port of the engine, and together with the less heating effect of air intake process, benefited from lower temperature of independent intake chamber, a highest volumetric efficiency which
makes engine produce a high torque of output on all speed range is achieved. The pump loss which consumes the part of engine power is eliminated Direct Fuel Injection Direct fuel injection can provide higher output and torque, while at the same time it also enhances the response for acceleration. Self‐Adapting Sealing System It can eliminate a number of seal plates or strips to achieve gapless seal and to provide most efficient and reliable sealing system with less friction. Vibration Free As major moving parts, vanes which are counted in little mass and operated symmetrically, the performance of the engine is very smooth. Hence, vibrations are eliminated. CONSTRUCTION& WORKING As earlier mentioned, the Green engine is a six phases, internal combustion engine with much higher expansion ratio. The term phase is used instead of stroke because stroke is actually associated to the movement of the piston. The travelling of the piston from bottom dead centre to the top dead centre or vice versa is termed a stroke. But, in this engine pistons are absent and hence, the term phase is used. The six phases are: intake, compression, mixing, combustion, power and exhaust. The engine comprises a set of vanes, a pair of rotors which houses a number of small pot‐like containers. It is here, in these small containers that compression, mixing, combustion are carried out. The engine also contains two air intake ports, and a pair of fuel injectors and spark plugs. Intake The air arrives to the engine through the direct air intake port in the absence of an air inlet pipe, throttle and inlet valves on the air intake system. A duct is provided on the sides of the vane and rotor. The duct is so shaped that when the air moves through, strong swirls generate when it gets compressed in the chamber. The air pushes the vane blades which in turn impart a proportionate rotation in the small rotor which houses the chambers. Compression The rushing air from the duct is pushed by the blades into the small chambers in the rotor. The
7
volume of these chambers is comparatively very small. As mentioned earlier, the compressed air is in a swirling state, ready to be mixed with the fuel which will be injected into the chamber when it will be place before the injector by the already rotating rotor. Mixing As soon as the chamber comes in front of the fuel injector, the injector sprays fuel into the compressed air. Because of the shape of the chamber, the fuel mixes well with the compressed air. Mixing phase has enough time to produce an ideal air‐fuel mixture as the spark plug is positioned towards the other end of the rotor or burner Combustion A spark flies from the plug into the air‐fuel mixture. . As soon as the whole charge is ignited, the burner rotates to position itself in front of the narrow exit. Power The expanded gas rushes out of the chamber through the narrow opening, thereby pushing the name in the process. The sudden increase in volume ensures that more power is released. Exhaust As the thermal energy is fully utilized, the exhaust gases bring along comparatively less heat energy. This mainly helps in the thermal efficiency of the engine. ADVANTAGES As obvious from the technical features which include effective innovations, the advantages of the Green engine over the contemporary piston engines are many. Small Size and Light Weight High Efficiency Because many great innovations are being employed in the engine design such as: direct air intake, sequential variable compression ratio, super mixing process, constant volume combustion Multi‐fuels Due to six phases of working principle, super air fuel mixing process and constant volume
combustion with controllable time, the Green engine becomes the only real multi‐fuel engine on our planet; any liquid or gas fuels can be burnt well. Ideal to Hydrogen Fuel Separation of working chambers from each other is an ideal design for any fuel to prevent backfire, especially for the hydrogen fuel. Low Cost Limited parts, small in size, light in weight and depending upon current mature materials and manufacturing technologies. By the above contents and proper explanation, it can be concluded that e green engine is sure to serve the purpose of mankind to large extent.

BUGATTI VEYRON – THE ENGINEERING MASTERPIECE!!! Am sure everyone has heard of the word BUGATTI VEYRON. Yes!! It’s the fastest street legal car in the world with a top speed of over 400 km/hr!!! The car is named after French racing driver Pierre Veyron, who won the 24 hours of Le Mans in 1939 while racing for the original Bugatti Company. The car wears the initials of vettori Bugatti, an Italian who built extremely fast n powerful cars between 1909 and 1947. Bugatti came back to life when VW bought the rights in 1999, in 2001 they decide to build a car with a whopping 1001 BHP which I think changed the dimensions of the automobile industry.
The Veyron has 2 transmissions built into one which makes the gear change extremely fast and helps it reach 60kmph from standstill in just 2.5s! Since the car is extremely fast, the brakes have to be very powerful and are made of hi tech carbon, ceramic and titanium. This combination of materials makes it work till 1800 degree Fahrenheit. But what if the temp exceeds 1800 f?? bugatti’s engineers had a solution to this problem . They designed a retractable rear spoiler which comes up automatically while braking and while cruising at very high speeds in order to keep the
vehicle firmly on the ground. The sensors for the spoilers come from a company which manufactures sensors for aircrafts.
Driving a Veyron would be like driving an aircraft on road because most of the parts are manufactured by the companies who manufacture parts for aircrafts. The Veyron has custom made Michelin tyres which can take it safely to the car’s top speed of 407kmph. The company says those tyres can withstand torture till 447Kmph!!
The bugatti’s factory which is in France has just 17 workers!! U may be surprised to know that this car doesn’t have a chassis at all. It’s made up of 3 different sections which are later joined together using bolts and nuts!! The car was tested in VW’s secret test track which has a 9km straight stretch. Interestingly, u cant’t see the other end of the track as its following the curvature of the earth!
VEYRON STATS
No. of cylinders – 16!! (2 V engines joined together)
Displacement – 8000cc
Material used in the engine – titanium (the material which you would find in an aeroplane!!)

THE T-800
Robot researchers led by Markus Grebenstein in Germany have taken a step towards making the T‐800 a reality this week by creating a super strong robot hand. It even looks a little a lot like the T‐800:
As the picture above shows, this hand is very strong and one of the fingers can be hit with a hammer at speed and not get damaged. It has 38 tendons with a motor attached to each finger and is of similar size to a human hand. Dexterity is built‐in and the hand has 19 degrees of freedom (one less than us) and a force of 30 N can be applied at the fingertips.
The hand was developed at the Institute of Robotics and Mechatronics at the German Aerospace Centre. The secret to its strength is a combination of a synthetic fiber called Dyneema and a spring attached to each tendon. That allows each finger to take a hard blow, but at the same time move to reduce the force while easily springing back to its original position.
The end result is a very strong hand with almost as much freedom of movement as a human hand. Movement speed at the joints can reach 2,000
8
degrees per second allowing the hand to snap its fingers.
Not only is it strong, but the use of springs on the joints allows the hand to monitor and adjust the force of its grasp based on the object being help. The lower the tension on the joints the softer the object must be and can therefore be grasped more lightly.
Employees are one of the most expensive and yet the greatest asset to any organization. They develop a set of skills that is acquired on the job through training and experience, and which increase that employee's value in the marketplace. In a successful ergonomics process, the employees are not "blamed" for injuries and/or waste, but the jobs themselves are assessed and changed when needed.
The main reason for the development of the hand was to improve the robustness of robotic hands in general. Grebenstein points out that even the most agile of robot hands can easily break with small amounts of pressure on them. This new design solves that problem without inhibiting movement or speed.
As for how much this hand cost to develop: it’s less than $135,000. Now the research team is turning its efforts to a two‐armed torso. Thankfully, no one yet seems to be working on legs so this thing could only escape by dragging itself across the floor.

ERGONOMICS:
A Management Asset and Manufacturing Excellence
Ergonomics is a study of the relationship between people and their working environment as a means to improve efficiency. A workplace whether it is a factory or an office, needs to be planned and systematically designed to provide the best possible support for quality work.
A new study shows that one‐third of workers in the western countries are chronically overworked and even more feel over overwhelmed and stressed by their jobs. The figures in Indian industries are not exactly known. We know in the short run that if employees are overworked, they are more resentful and angry and commit more mistakes. In the long run, we are talking about the effects of stress and work conditions on health.
Ergonomics: A Management Asset
Ergonomics deals with risk‐return trade‐offs. Ergonomics engineering mitigate risk by engineering out a problem. By removing the risk, potential for additional costs and labour problems can be ended and can manage and control the expenditure for the solution. Risk can be transferred through means such as insurance coverage. With this method, you are paying the insurance company to assume the risk but you still pay.
The ergonomics engineering can provide the roadmap to cost reduction by imparting the knowledge and increasing the intellectual capital for all employees. By using intellectual capital to reduce costs, it can maintain experienced employees rather than the "revolving door" syndrome, create solutions to jobs that produce risk factors to the human body, understand "upstream" design prior to cutting a piece of steel in the plant, train office employees in the proper
9
adjustability of their equipment, educate healthcare workers in proper lifting techniques, take warehousing and supply chains and design in solutions while designing out problems.
Ergonomics : A Manufacturing Excellence Companies need to meet the expectations of "doing more with less". To achieve this one approach that has proven effective in scores of manufacturing companies is to leverage the efforts of ongoing improvement initiatives to accelerate ergonomics improvements. Generically referred to as "manufacturing excellence", these initiatives range from Lean Manufacturing to Six Sigma to Demand Flow Technology. The techniques may differ, but they all have a common goal: drive bottom‐line improvements by working smarter. Manufacturing excellence initiatives are how things get done in manufacturing today. If you want to modify a manufacturing process to reduce ergonomic risks, the simplest approach is to align with the Kaizen improvement team activities. Integrating your ergonomics efforts with these initiatives, however, means one have to ensure that ergonomics process is systematic and data‐driven.
The ability to manage ergonomics knowledge represents one of the primary opportunities for achieving substantial savings, significant improvements in human performance, and competitive advantage.Manufacturing excellence initiatives do not tolerate opinion and intuition, decisions are formalized and projects are funded based on data analysis
Engineering ergonomics can foster continuous improvement in any organization by using the science for changing a corporate culture through the education and transfer of knowledge. Training an organization's engineering staff in applied ergonomics for processes, product design, design for manufacturing and assembly, equipment design and selection, supply chain management, facility environments and maintenance can produce a variety of benefits. Other personnel such as health, safety, maintenance, purchasing and production employees need to be trained after the engineers. This allows a natural, logical chain of events whereby an employee identifies an ergonomic risk factor and the engineer has the knowledge to understand and develop the solution to reduce or eliminate the hazard. Otherwise, labor and management may have a real schism when a risk is found and no one can change it.
- Ergonomics can impact work organization by adding to efficiency and reducing errors and waste. Ergonomics can identify risk factors to reduce workers’ compensation, disability costs and lost work time costs. Ergonomics leads to the design of workstations and accessories that are comfortable, and helps create new designs for products, equipment and tools that enhance productivity.
- The quantity and quality of work can be
improved by using the correct layout plan, storage, furniture, colour scheme, and lighting. Office interiors have been proved through research to influence the behaviour of employees. Appropriate colour schemes, which are preferably pastel or bluish, have been proved to help in concentration and work productivity. Excessively bright or dull colours should be avoided. Health of employees depends to a certain extent on the interior design. Dull stodgy colours, scattered storage spaces and uncomfortable work areas can slow down work productivity and cause illnesses and absence from work. The opposite happens to be true. If the design can incorporate pleasant, motivating interiors with comfortable chairs and desks with proper storage and a layout plan, the possibilities of better work progress is likely.
In the present scenario ergonomics engineering present many avenues for students and engineers from all streams to specialize in this flourishing field. Organizations and universities has realized the worth of this specialized science of ergonomic engineering and many courses and training programs are been conducted. Ergonomics engineering is not only an asset to the management, it also a manufacturing excellence.

INDIAN DEFENSE FLYING WITH OWN WINGS
Indian defense is proud about the recent developments in its R&D Division which came out with Light Combat Aircraft‐ TEJAS.
Tejas, the Indian Light Combat Aircraft, re‐scripted the history of Indian Aeronautics in Golden letters. Success story of Tejas is an epitome of corporate collaboration involving R&D laboratories of DRDO, CSIR, CEMILAC, DGAQA, and Defence PSUs like HAL, BEL and many more. Private sector participants and prominent Educational Institutions, all coordinated by nodal organization Aeronautical Development Agency (ADA) was established with the sole purpose of developing Tejas, delta‐winged machine.
The Tejas, or ‘radiance’, is an indigenous fighter aircraft jointly developed by Aeronautical Development Agency and Hindustan Aeronautics limited. It is the smallest light weight, multi‐role, single‐engine tactical fighter aircraft in the world and is being developed in single‐seat fighter and twin seat trainer variants for the Indian Air Force and Indian Navy. The aircraft will enter service to replace the erstwhile warhorse of the IAF, the MiG21 (Mikoyan‐ Gurevich MiG‐21). For the Navy, the Tejas will replace the Sea Harrier and complement the MiG 29K. The Tejas has been conceptualized and designed by India, and its open architecture design will allow the designers to continuously adapt and upgrade it to meet the challenges of modern warfare. Its small size and footprint will enable frontline units to quickly and effectively deploy it for combat operations. The sheer flexi that Indian Design and development brings to the Tejas weapon system means that it will be a simple matter to modify and upgrade the Tejas at any stage of its service life, thus making it the most cost effective fighter platform for the IAF in the decades to come.
Tejas‐LCA is ready for the Initial Operational clearance (IOC). After the certifications namma Bengaluru based state owned aircraft maker‐ Hindustan Aeronautics Limited (HAL) will start rolling out Tejas in the next few months.
“The good thing about Tejas is that it’s a pilot’s aircraft. It has been designed by the pilots for and for the pilots.”
- Group Captain Sumeet Krishna

Today, with products being designed in one country and manufactured in others, such cplace.tifathimplications with good parts being rejected or badparts being accepted. It helps if the inspector hasan understanding of theto function. A good drainTto y design intent so inspectors know how to do their measurements.
What is GD&T? D&T is a communiG
particularly helpful in a global economy where parts may be made in one par of the world and used in another. GD&T is increasingly being accepted as the best way of specifying 3‐D design dimensions and tolerances on engineering design drawings. The currently recognized GD&T standard in the United States is ASME Y 14.5M (1994). The ISO parallel of ASME Y14.5 is ISO 1101. Although both standards have the same goal, they are not exactly equivalent, and it is important to know to which standard the drawing complies when measuring a part. As design software and machine tools have
become more capable, ina
dimensions thain
An example of a part with critical dimensions and tolerances is a plastic part designed to eliminate fasteners. By making a part with features that mate to another part, assembling those parts can eliminate the need for screws, reducing costs in
parts and in assembly operations. However, sizes and positions of those mating features can be criti‐ cal, with extremely tight tolerances. An inspector measuring those features, but referencing dimensions from the wrong positions may make the wrong decision. Properly specifying and using datums in GD&T can help avoid such errors.
Inspection equipment measures parts for two main reasons—production acceptance, which is compliance to specified tolerances, and troubleshooting or problem solving of the manufacturing process.
GD&T drawings typically reflect the first reason: they specify conditions, or tolerances, for part acceptance from a functional point of view. A drawing will have one or more datum reference frames (DRF) with tolerances located and oriented relative to each DRF. The ability to properly construct a DRF during the inspection process is crucial to the succes of the evaluation. To properly construct a DRF, it is important to strictly follow the rules as specified by the standards ASME Y14.5 and ASME Y14.5.1. These ules determine thrdegrees of freedom that are eonstraints the primary datum csecondary and tertiary datums, and the mathematical fitting technique used to construct the individual datum simulators. A typical old‐fashioned mea uremen would simply execute a measuand print the results. While this approach is acceptable for certain cases such as verifying sizes of features, it is not acceptable in all cases and will lead to incorrect results when the drawing contains DRFs that do not fully constrain all the degrees of freedom or have maximum material condition (MMC) or least material condition (LMC) modifiers attached to a datum reference.
In these cases the DRF can only be correctly determined after all of the measured points in that DRF are collected. This means that before starting the evaluation process, the nominal data (CAD) tolerancing information—datums, toler ance callouts and the measured ata must be available. This is calle a GD&T Evaluation Environment.
W rking in GD&T envir nt The first step to working in this environment is to import the nominal data of the geometry typically available as a CAD model. It is important to understand that CAD design software and

CAD software may introduce uncer‐ tainties into the inspection process. One example is rounding of dimensions. If features used as datums hav
cIGES, VDA, STEP or other formats may modify or lose some geometrical data. It is important to understand that even if the metrology software claims that it is able to use native CAD ormats, the interpretation of these formats is left to the measuring software and can become a source of discrepancies duein

software. During this process good GD&T software would have some tools available to expose any CAD import issues. The next step is to import the measured data. If the data is collected by a CMM‐like device, it is imported directly, but if thenoncontact technology such as a laser scanner, there may be a need for intelligent data filtering. Intelligent data filtering means that the measured data is evaluated and, if needed, measurement noise is emoved and the number of points is reduced. This p
Is least squares enough? Best‐fitting is fundamental to the GD&T evaluation process. Best‐fitting is used to correctly construct the DRF and then to optimize all the measured deviations. The difference between good and bad evaluation software is its ability to use the appropriate not the most convenient fitting technique. There are a number of fitting echniques availablet ‐max, tolerance envelope, fitting with constraints, weighted best‐fitting, maximum inscribed cylinder (circle), minimum circumscribed cylinder (circle), and tangent line or plane. These techniques exist for a reason and address specific goals. They can be applied to geometric element fitting or to point clouds to surfaces best fitting.
Consider DRF creation. Assume evaluating a part with a plane for primary datu ‘A’ and a perpendicular inside cylinder deriving a secondad
teaverage plane instead of the necessary tangent plane. A tangent plane properly simulates the way the part will work. At the same time, free least squares inside cylinder instead of a maximum inscribed cylinder calculated constrained to datum A, will lead to creation of a DRF which does not represent how the part functions. As a result there will be a systematic error for all of the results evaluated in that DRF and certainly a probability of bad parts being accepted and good being rejected. Tech Tips
• GD&T makes it easier for designers to convey design intent so inspectors know how to do their measurements.
• GD&T drawings typically specify conditions, or tolerances, for part acceptance from a functional point of view.
• Best fitting is used to correctly construct the DRF and then to optimize all the measured deviations.
• Using ASME Y14.5 and ASME Y14.5.1 is the right way to go when specifying drawing requirements and evaluating parts for acceptance.

The production of GP from graphite also provides a remarkable amount of added value for the mining, material processing and manufacturing industries in Australia. In the last decade, metals have increasingly and rapidly been replaced with carbon‐based materials. Australian mines have immense graphite resources making the new material a favourable option to industry as an economical, home‐grown and world‐class technological advancement for mass production and industrial application.

Gone are the days when we had to slog
in classrooms and follow the lectures accurately, scribble down notes knowing well that even if we intended to miss a single class for a reason, indeed we would be in two minds as there was a fair chance of losing a good amount of that important lecture for a subject which was considered a mass backlog paper and even if we managed to get the notes later from our friends, it was a real struggle to understand it.
Cut to the present day. It is now possible to obtain a degree from Harvard University while you are relaxing in your living room. It is possible to access MIT courses on your personal laptop and even if you are not a student at Stanford University, you can still catch most of the lectures on Youtube.
Wait I know what you guys are probably thinking. Where do our country India stand in this race of imparting free technical knowledge in the global stage. Well I have an answer.
It is called NPTEL. Here’s all that you need to know about it and hence broaden your horizons.
NPTEL
IITs and IISc
Bangalore, and is funded by the Ministry of Human Resources Development of the Government of India.
As of December 2009, over 250 courses were available online. The course videos are available in streaming mode, and may also be downloaded for viewing offline. The video files are also viewable via the IIT Channel in Youtube.
Seven IITs and the Indian Institute of Science (IISc) have worked together to develop web and video based material for basic undergraduate science and engineering courses in order to enhance the reach and quality of technical education in India.
The NPTEL Program
Participating Institutions
• Indian Institute of Science, Bangalore • Indian Institute of Technology, Delhi • Indian Institute of Technology, Guwahati • Indian Institute of Technology, Kanpur • Indian Institute of Technology, Madras
(coordinating Institute) • Indian Institute of Technology, Mumbai • Indian Institute of Technology, Roorkee • Indian Institute of Technology, Kharagpur
History of the Programme
The idea of having a Technology enhanced learning initiative involving IITs and Indian Institutes of Management (IIMs) was first proposed by IIT Madras in the year 1999 immediately following a Workshop on Technology Enhanced Learning (WoTEL) conducted in Chennai in collaboration with Carnegie Mellon University (CMU), Pittsburgh, USA.
Cost of the initiative: The Ministry of Human Resource Development, Government of India approved funding of 20.47 crores (204.7 million) of Indian Rupees for Phase I for three years from June 2003 till June 2006, which was eventually extended till June 30, 2007.
Following that, significant infrastructure for the production of video‐based teaching material by the institutes was set up. In the first phase of the NPTEL project (June 2003‐June 2007), 110 video courses and 129 web‐based courses were
20
developed by the faculty members of these institutions.
Future Plans of the Project:
Phase II: The next phase of the programme is now ongoing. Over 1000 web and video courses will be created.
There are several enhancements being included for Phase II
• All IITs and IISc will participate as partners. In addition NIT and other premier University faculty will have the opportunity to join for open content creation as associates.
• Private industries will be called on to provide value‐added case studies and experiential learning.
• There is increased emphasis on having a modular structure for the courses
• Question banks and case studies will be included as part of the courses where applicable
• The course materials will be developed to contain greater relevance to professional examination and industrial practices
• Course specific NPTEL wiki's for increased interaction and user‐content generation
Engineering Disciplines for NPTEL Courses
In Phase I, five branches of engineering (Civil, Electrical, Electronics and Communication, Computer Science and Engineering, and Mechanical) were addressed in the first phase. Each Institute identified the courses in which it would like to participate as video (V) or Web (W) based content contributor. The core courses common to all these disciplines including basic science and engineering were addressed by a core courses group.
As of December 2009, web and video courses in the following disciplines are available.

CAREER OPPORTUNITIES IN ROBOTICS
In the last few decades technology has been the major force driving industry forward. Automation has been the most important component to instill efficiency into industrial processes. On the other hand, human resources to achieve automation have also been required in great numbers. Robotics has been at the forefront of technological innovation into more and more automation. It is the science and technology that drives robots to do all sorts of process related jobs more efficiently than humans can ever do without getting tired. Robots are mechanical devices that are computer controlled. The development of robotics and robots obviously requires human resource, expert in diverse areas. Requirement list begins with mechanical engineers, computer scientists, process technologists, experts in material sciences, and system integrators. Further field needs quality control engineers, instrumentation engineers, and control system engineers. The mechanical engineers, control system designers, and information technology experts are the most prominent personnel required for robot design, construction, and actual operation of robots for specific industrial processes. The automobile industries across the globe are extensively using robots in assembly lines. Their development requires knowledge about automobile assembly processes and mechanical engineering. Control system engineers, software developers, instrumentation engineers, and electronics engineers are also required for developing and improving them. Information technology (IT) is also an area where robots are used. Intel and AMD use robots in developing the latest microchips. Nanotechnology is a recent domain wherein robots are seen as requirement. Besides industry, robots are
being used more and more for personal use as toys or as security guards. Robots are also used in
cleaning nuclear active rooms/areas. Recent developments and researches have opened up the window of medical sciences wherein robots are used to assist surgeries and in few applications used to assist the support staff in hospitals in better caring of patients. Opportunities to kick start a career are plenty and readily available in robotics in these budding fields. Besides all these fields, you can also find an opening in off the focus areas such as‐ deep sea ocean exploration, the study of volcanoes, the Antarctic, and in archaeology. For quote ‘A hitherto unknown tunnel was found in the main pyramid at Giza in Egypt through use of a miniature robot’. Astronomy is the field wherein robots play an important role in many of the celestial expeditions. We can all remember the Pathfinder robotic vehicle still working on Mars. It is important to see that robots are used exclusively in certain areas and conditions. They are specifically used where the reach of humans is highly impossible, such as hostile environments‐ dusty, chemically active, high temperature applications and many such areas where the involvement of humans may be hazardous to health. It is therefore not very difficult to forecast that, in the coming years more and more career opportunities will be forthcoming in the field of robotics for young engineers‐ brain filled with innovative ideas and knowledge. An interest in robotics and systems development is an important pre‐requisite to pursue a career. A basic degree in a compatible engineering, science, or technology discipline is what is essentially required. You will have better growth in robotics if you gain worthwhile experience in the initial two years of your career.

Motivational Story
Boy was born to a couple after eleven years of marriage. They were a Loving couple and the boy was the gem of their eyes. When the boy was around two years old, one morning the husband saw a medicine bottle Open. He was late for office so he asked his wife to cap the bottle and keep it in the cupboard. His wife, preoccupied in the kitchen totally forgot the matter. The boy saw the bottle and playfully went to the bottle fascinated by its colour and drank it all. It happened to be a poisonous medicine Meant for adults in small dosages. When the child collapsed the mother hurried him to the hospital, where he died. The mother was stunned. She was terrified how to face her husband. When the distraught father came to the hospital and saw the dead child, He looked at his wife and uttered “I am with you" The husband's totally unexpected reaction is a proactive behavior. The Child is dead. He can never be brought back to life. There is no point in finding fault with the mother. Besides, if only he had taken time to keep the bottle away, this would not have happened. No one is to be blamed. She had also lost her only child. What she needed at that moment was consolation and sympathy from the husband. That is what he gave her. If everyone can look at life with this kind of perspective, there would be much fewer problems in the world. "A journey of a thousand miles Begins with a single step." Take off all your envies, jealousies, Unforgiveness, selfishness, and fears. And you will find things are actually not as difficult as you think. MORAL OF THE STORY Sometimes we spend time in asking who is responsible or whom to blame, Whether in a relationship, in a job or with the people we know. By this Way we miss out some warmth in human relationship.

Make a Difference: I awoke early, as I often did, just before sunrise to walk by the ocean's edge and greet the new day. As I moved through the misty dawn, I focused on a faint, far away motion. I saw a youth, bending and reaching and flailing arms, dancing on the beach, no doubt in celebration of the perfect day soon to begin. As I approached, I sadly realized that the youth was not dancing to the bay, but rather bending to sift through the debris left by the night's tide, stopping now and then to pick up a starfish and then standing, to heave it back into the sea. I asked the youth the purpose of the effort. "The tide has washed the starfish onto the beach and they cannot return to the sea by themselves," the youth replied. "When the sun rises, they will die, unless I throw them back to the sea." As the youth explained, I surveyed the vast expanse of beach, stretching in both directions beyond my sight. Starfish littered the shore in numbers beyond calculation. The hopelessness of the youth's plan became clear to me and I countered, "But there are more starfish on this beach than you can ever save before the sun is up. Surely you cannot expect to make a difference." The youth paused briefly to consider my words, bent to pick up a starfish and threw it as far as possible. Turning to me he simply said, "It made a difference to that one." I left the boy and went home, deep in thought of what the boy had said. I returned to the beach and spent the rest of the day helping the boy throw starfish in to the sea. Based on the story by Loren Eisley

Musings of a Confused Engineering Mind
“Should I wear this red tie or should I pick up the maroon one instead for today’s meeting with my client?”...”Should I laze around in the house for the weekend or just chill out with my friends
at the discotheque?” I believe each one of us at some point of the day go through a similar phase of indecisiveness.
Any guesses? The word is “Confusion”. Yes, it is this confusion that rules the world and beyond. Till date even the top notch scientists are speculative over the origin of the universe and space-time and hence they had to seek refuge into a number of theories such as the Big-Bang Theory, the String-Theory among others. But this doesn’t end confusion from their minds for they are
constantly at work to find a full-proof theory that would describe every property and characteristics of the universe and answer the myriad questions hurled by the critics out there.
Now that was about the scientific world where confusion reigns supreme. Now coming to our practical world, confusion plays no lesser part in almost every aspect of our lives. Very few
smart and able men can keep confusion at bay. The remaining are confused right from dawn to dusk. I belong to the latter category.
About me, I was as much confused in childhood as I am now. Confusion seems to be synonymous with my name. Confused? Let me clarify. My name is an amalgamation of a complex set of
unpronounceable syllables as a result of which often people find it difficult to pronounce my name and as a result end up spelling it wrongly. No doubt most of my marks card bare the same
name but with different spellings. My fate! Another trait of my eternal confusion is that it was only when I was in the seventh grade that I came to distinguish between the left and right sides over which I get confused sometimes even
now. Moreover, after being confused for all these years I can say that I’ve attained some sort of
mastery over this special trait possessed by me. My confused state of mind can be divided into three categories.
The first one is that I am a person who is scientifically confused. No doubt I nursed a personal grudge against Newton when I was in school. As a result I ended up messing my grades quite
often in school which was followed by a letter to my parents from the principal. But interestingly or rather confusingly the letter never found its way to my home.
However, I am proud to belong to this class of scientifically confused people because I personally believe that all great scientists were a confused lot and in the process of removing their confusion they ended up discovering or inventing something extraordinarily great. Now I
am not saying that I am great for I have my confusions over that as well! Secondly, I’m a person who is spiritually confused. I am confused for that matter because if
God is one and all religions preach the same tenets of finding God, then how come so much hatred and sin in the name of religion all over the world. All these make me all the more
confused. Lastly, I am a person who is simply confused. I sometimes wonder had there been some sort of
Confusion Quotient (CQ) to measure the degree of confusion of the mind, I am sure I would have had a high CQ level.
None of my tasks are completed without the timely intervention of confusion. But I must say that I am proud to possess such a powerful quality for with the help of this special trait many
minds have produced many things unheard of before. So why can’t I? With this bit of solace I continue my journey hand in hand with this faithful companion for many
more confusing days to come in future...
