Mechatronics is a design process that includes a combination of mechanical engineering, electrical engineering, telecommunications engineering, control engineering and computer engineering. Mechatronics is a multidisciplinary field of engineering, that is to say, it rejects splitting engineering into separate disciplines. Originally, mechatronics just included the combination of mechanics and electronics, hence the word is a combination of mechanics and electronics; however, as technical systems have become more and more complex the word has been broadened to include more technical areas.

The word "Mechatronics" was originally "Japanese-English" word created by Mr. Tetsuro Mori, who was an engineer of Yaskawa Electric Corporation and the word "Mechatronics" was registered as Trademark by the company in Japan with the registration number of "46-32714" in 1971. However afterward, the company released the right of using the word to public, and the word "Mechatronics" didn't only stay in Japan, but also introduced as a native English word. Nowadays, the word is translated in each language and the word is considered as an essential term for industry.

French standard NF E 01-010 gives the following definition: “approach aiming at the synergistic integration of mechanics, electronics, control theory, and computer science within product design and manufacturing, in order to improve and/or optimize its functionality".

Many people treat "mechatronics" as a modern buzzword synonymous with "electromechanical engineering". However, other people draw a distinction between an "electromechanical component" - does not include a computer; an electro-mechanical computer (such as the Z4) - does not include an electronic computer; vs. a "mechatronic system" - a computer-controlled mechanical system, including both an electronic computer and electromechanical components.

A mechatronics engineer unites the principles of mechanics, electronics, and computing to generate a simpler, more economical and reliable system. The term "mechatronics" was coined by Tetsuro Mori, the senior engineer of the Japanese company Yaskawa in 1969. An industrial robot is a prime example of a mechatronics system; it includes aspects of electronics, mechanics, and computing to do its day-to-day jobs.

Engineering cybernetics deals with the question of control engineering of mechatronic systems. It is used to control or regulate such a system (see control theory). Through collaboration, the mechatronic modules perform the production goals and inherit flexible and agile manufacturing properties in the production scheme. Modern production equipment consists of mechatronic modules that are integrated according to a control architecture. The most known architectures involve hierarchy, polyarchy, heterarchy, and hybrid. The methods for achieving a technical effect are described by control algorithms, which might or might not utilize formal methods in their design. Hybrid systems important to mechatronics include production systems, synergy drives, planetary exploration rovers, automotive subsystems such as anti-lock braking systems and spin-assist, and everyday equipment such as autofocus cameras, video, hard disks, and CD players.
