Introduction to Mechatronics

Mechatronics is a word originated in Japan in 1980s to denote the combination of technologies which go together to produce industrial robots.

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.’’

The various fields that make up Mechatronics is shown in Fig

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.

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.

Mechatronics requires thinking products and processes so transverse. Mechatronics is “burst the walls, with a steering matrix. The pilot at the highest level of the enterprise is essential in this context, to afford in front needs to be implemented.

The design should no longer be sequentially: the mechatronics approach requires thinking about the product as a whole (all skill areas at a time) and not by separating the mechanical part, then electronics, then the sensor – actuators and computers at risk to achieve additional cost prohibitive.


The project manager must master the various areas and not be an expert in one of mechatronics technology: It was necessary to avoid watching the draft with an eye mechanics or electronics. The pilot is here, as elsewhere, the role of a conductor, not a virtuoso.

The phases of integration are sensitive, such that an electronic assembly in a machine shop (or vice versa). There are telescoping and areas of project management and competence, which involves work that is done jointly, to ultimately obtain not a purely mechanical or purely electronic, but a set that combines the advantages of 2, which can not be separated.

01- mechatronics-meaning

          Mechatronics, which is also called mechatronic engineering, is a multidisciplinary branch of engineering that focuses on the engineering of both electrical and mechanical systems, and also includes a combination of robotics, electronics, computer, telecommunications, systems, control, and product engineering. As technology advances over time, various subfields of engineering have succeeded in both adapting and multiplying.

The intention of mechatronics is to produce a design solution that unifies each of these various subfields. Originally, the field of mechatronics was intended to be nothing more than a combination of mechanics and electronics, hence the name being a portmanteau of mechanics and electronics; however, as the complexity of technical systems continued to evolve, the definition had been broadened to include more technical areas. The word mechatronics originated in Japanese-English and was created by Tetsuro Mori, an engineer of Yaskawa Electric Corporation.

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, the word begun being used across the world. Nowadays, the word is translated into many languages and the word is considered as an essential term for industry.

“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 robotics and electromechanical engineering.

           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.


  • Actuators and sensors
  • Signals and conditioning
  • Digital logic systems
  • Software and data acquisition systems
  • Computers and display devices.


    Sensors and actuators mostly come under mechanical system. The actuators produce some action or cause motion. The sensors detect the state of system parameters, inputs, and outputs. the various actuators used in mechatronic system are pneumatic or hydraulic actuators, electro mechanical actuators, electrical motors such as DC motor, AC motor, stepper motors, servo motor, and piezo electric system, are linear and rotational sensor, acceleration sensor, force, torque, pressure sensor, temperature sensor, proximity sensors, light sensor.


01-signals and conditioning
                 The mechatronic system deal with two types of signals and conditioning such as input and output. the various input signal conditioning devices used in mechatronic system are discrete circuits amplifier A/D convertors, D/D convertors.


                 Digital logic devices control overall system operations the various digital logic system used in mechatronic system are logic circuits, micro controller, programmable logic controllers, sequencing and timing controls.


Data acquisition system acquires the output signals from sensor in the form of voltage. frequency, resistance, etc. and it is inputted into the microprocessor or computer. software is used to control the acquisition of data through DAC board.


01-display devices
Computers are used to store large no of data and process further through software. Display devices are used to visual feedback to the user. The various display device used in mechatronic system are LEDs, CRT, LCD, Digital display etc.
