MECHATRONICS SYSTEM Mechatronics basically refers to mechanical electronic systems and normally described as a synergistic combination of mechanics, electrical, electronics, computer and control which, when combined, make possible the generation of simple, more economic, and reliable systems. The term "mechatronics" was first assigned by Mr. Tetsuro Mori, a senior engineer of the Japanese company Yaskawa, in 1969.

Embedded Systems  A combination of hardware and software which together form a component of a Mechatronics systems. An embedded system is designed to run on its own without human intervention, and may be required to respond to events in real time.

Mechatronics Working Definition for us Mechatronics is the synergistic integration of sensors, actuators, signal conditioning, power electronics, decision and control algorithms, and computer hardware and software to manage complexity, uncertainty, and communication in engineered systems.

History  Mechanical Engineering experienced an exponential growth in the early 19th century because of the industrial revolution.  The rise of semiconductors in the 1950s and computers in the 1980s have revolutionized all engineering products and processes which in turn affected mechanical engineering systems.  The term mechatronics was first used in the late 1960s by a Japanese Electric Company to describe the engineering integration between mechanical “mecha” and electronics “tronics” systems.

 Since then it has spread throughout Europe and is growing is the USA.  Today, many mechanical systems use some form of electronics and computers to control its functionality.  Mechatronics system engineering has gained much recognition and importance in the industrial world.  In the late 1970s, the Japan Society for the Promotion of Machine Industry (JSPMI) classified mechatronics products into four categories

What is mechanical engineering?  Mechanical engineering is one of the oldest branches of engineering, and it deals with designing a component, machine, system or a process by using principles of motion, energy and force. That means that the work of a mechanical engineer focuses on creating new technology that meets and satisfies human needs; as you can see, touch and use the work of mechanical engineers each day: it’s the engine of a car, the printer that helps you copy a document, the air-conditioning that cools you in the hot summer days, just to mention a few basic examples.  Basically, a mechanical engineer is responsible for creating the mechanical systems of any machinery or device that is meant to move. They also test and manufacture these systems and some mechanical engineers engage in areas of research such as nanotechnology, development of composite materials, biomedical applications, or environmental conservation.

Elements of Mechanical system  Mechanical elements refer to mechanical structure, mechanism, thermo-fluid, and hydraulic.  Mechanical elements may include static/dynamic characteristics.  A mechanical element interacts with its environment purposefully.  Mechanical elements require physical power to produce motion, force, heat, etc.

Elements of Mechatronics Typical knowledgebase for optimal design and operation of mechatronic systems comprises of: –  Dynamic system modeling and analysis  Thermo-fluid, structural, hydraulic, electrical, chemical, biological, etc.  Decision and control theory  Sensors and signal conditioning  Actuators and power electronics  Data acquisition A2D, D2A, digital I/O, counters, timers, etc.  Hardware interfacing  Rapid control prototyping  Embedded computing
