A formal definition of Mechatronics is ``the synergistic integration of Mechanics and Mechanical Engineering, Electronics, Computer technology, and IT to produce or enhance products and systems.’’ A graphical representation of Mechatronics is shown in Fig. 1. Examples of such systems are Computers, Disk drives, Photocopiers, Fax machines, VCR, Washing machines, CNC machine tools, Robots, etc. Today’s modern cars are also mechatronics product with the usage of electronic engine management system, collision detection, global positioning system, and others. Design Engineering Manufacturing Mechanical Mechatronics Electronics Figure 1 Graphical representation of Mechatronics. Even though many people believe that the presence of mechanical, electrical, electronic components, and computers make a system mechatronics, others do not feel the same as there is nothing wrong with the individual identity. Hence, the term mechatronics should be used to represent a different meaning, namely, “a design philosophy,” where mechanical, electrical, electronics components, and IT should be considered together in the design stage itself to obtain a compact, efficient, and economic product rather than designing the components separtately. This is illustrated in Fig. 2. The concept of mechatronics is very important today to meet the customers’ ever increasing demands and still remain competitive in the global market. Very often a mechanical engineer without the mechatronics background is considered equivalent to a mechanical engineer without the engineering drawing knowledge. In India, we always look towards west for our technological requirement even though Indians excel everywhere except in India. So the issue is not the Indians’ capabilities but their environment. Here, the author wishes to emphasize the creation of such environment through sharing his experience of establishing the Mechatornics Laboratory at IIT Delhi in 2001, conducting and participating in the workshops/open-

By sharing the information and experiences, everybody should be in a position to decide their own strategy for their indigenous development rather than buying the same, which may be a technologically better product but the technology inside it will not be known as it is not told (a trade secret). So, one has to develop his or her own technology to stay competitive.
