Mechatronics is a concept of Japanese origin (1970’s) and can be defined as the application of electronics and computer technology to control the motions of mechanical systems (figure 1.1.1). Figure 1.1.1 Definition of Mechatronics It is a multidisciplinary approach to product and manufacturing system design (Figure 1.1.2). It involves application of electrical, mechanical, control and computer engineering to develop products, processes and systems with greater flexibility, ease in redesign and ability of reprogramming. It concurrently includes all these disciplines. Figure 1.1.2 Mechatronics: a multi-disciplinary approach Mechatronics can also be termed as replacement of mechanics with electronics or enhance mechanics with electronics. For example, in modern automobiles, mechanical fuel injection systems are now replaced with electronic fuel injection systems.…
