3. INTRODUCTION OF MECHATRONICS “The word, mechatronics is composed of mecha from mechanics and tronics from electronics. In other words, technologies and developed products will be incorporating electronics more and more into mechanisms,.” T. Mori, “Mechatronics,” Yasakawa Internal Trademark Application Memo, 21.131.01, July 12, 1969. Example: automatic washing machine, digital fuel injection system, engine management system. Etc

5. Multi-disciplinary scenario Mechatronics is the synergistic (Together) combination of mechanical engineering, electronic engineering, control engineering and systems thinking in the design of products and manufacturing processes”. Multi-disciplinary products are not new; they have been successfully designed and used for many years. Most common is the electromechanical system. It employs a sequential design-by-discipline approach. For example in the design of electromechanical system three stages of design are adopted. They are design of mechanical system, design of microelectronic system and control system. Each design application follows the completion of the previous one. It‟s having so many drawbacks, to overcome this Mechatronics has been developed and it uses concurrent engineering
6. Origin of Mechatronic system The word Mechatronics was coined by Japanese in the late 1970‟s to describe the philosophy adopted in the design of subsystem of electromechanical systems. The field of Mechatronics received the international recognitions only in the last few years. The field has been derived by rapid progress in the field of microelectronics. At R&D level the following areas have been recognized under Mechatronics discipline. 1. Motion control actuators and sensors 2. Micro devices and optoelectronics 3. Robotics 4. Automotive systems 5. Modeling and design 6. System integration 7. Manufacturing 8. Vibration and noise control.
7. Evaluation of Mechatronics The technology has evolved through several stages that are termed as levels. The evolution levels of Mechatronics are: 1. Primary level Mechatronics (first) 2. Secondary level Mechatronics (second) 3. Tertiary level Mechatronics (third) 4. Quaternary level Mechatronics (fourth)
8. Primary level Mechatronics (first) In the early days Mechatronics products were at primary level containing devices such as sensors, and actuators that integrated electrical signals with mechanical action at the basic control level. Examples: electrically controlled fluid valves Secondary level Mechatronics (second) This level integrates microelectronics into electrically controlled devices. Examples: cassette player.
9. Tertiary level Mechatronics (third) Mechatronics system at this level is called ‘smart system’ The control strategy includes microelectronics, microprocessor and other application specific integrated circuits‟ (ASIC). Examples: DVD player, CD drives, automatic washing machine, CD drives, etc Quaternary level Mechatronics (fourth) This level includes intelligent control in Mechatronics system. The level attempts to improve smartness a step ahead by introducing intelligence and fault detection and isolation (FDI) capability system. Examples: artificial neural network and fuzzy logic technologies.
