Mechatronics engineering, also called mechatronics, is the synergistic integration of mechanical, electrical, and computer systems employing mechanical engineering, electrical engineering, electronic engineering and computer science and 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, electrical and electronics, hence the name being a portmanteau of the words " mechanics" and "elec tronics"; however, as the complexity of technical systems continued to evolve, the definition had been broadened to include more technical areas.
Many people treat mechatronics as a modern buzzword synonymous with automation, robotics and electromechanical engineering.[Lawrence J. Kamm (1996). Understanding Electro-Mechanical Engineering: An Introduction to Mechatronics. John Wiley & Sons. ]
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".[Bolton, W. Mechatronics. Pearson, 6th edition, 2015. ]
History
No later than in 1951, the word
mechatronics was used in an advertisement of the company Servomechanisms, Inc., as can be seen in the journal
Nucleonics, vol. 9, issue 3 on page 99.
The word mechatronics originated in Wasei-eigo 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. The company later released the right to use the word to the public, and the word began being used globally. Currently the word is translated into many languages and is considered an essential term for advanced automated industry.[Msc. Mechatronics and Automation Engineering, University of Strathclyde Glasgow, Institution of Engineering and Technology, United Kingdom. Retrieved 29 November 2020.]
With the advent of information technology in the 1980s, microprocessors were introduced into mechanical systems, improving performance significantly. By the 1990s, advances in computational intelligence were applied to mechatronics in ways that revolutionized the field.
Description
A mechatronics engineer unites the principles of mechanics, electrical, electronics, and computing to generate a simpler, more economical and reliable system.
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 , which might or might not utilize in their design. Hybrid systems important to mechatronics include production systems, synergy drives,
exploration rovers, automotive subsystems such as anti-lock braking systems and spin-assist, and everyday equipment such as autofocus cameras, video, , CD players and phones.
Subdisciplines
Mechanical
Mechanical engineering is an important part of mechatronics engineering. It includes the study of mechanical nature of how an object works. Mechanical elements refer to mechanical structure, mechanism, thermo-fluid, and hydraulic aspects of a mechatronics system. The study of
thermodynamics, dynamics,
fluid mechanics,
pneumatics and
hydraulics. Mechatronics engineer who works a mechanical engineer can specialize in
Hydraulic system and
Pneumatic System, where they can be found working in automobile industries. A mechatronics engineer can also design a vehicle since they have strong mechanical and electronical background. Knowledge of software applications such as computer-aided design and computer-aided manufacturing is essential for designing products. Mechatronics covers a part of mechanical syllabus which is widely applied in automobile industry.
Mechatronic systems represent a large part of the functions of an automobile. The control loop formed by sensor—information processing—actuator—mechanical (physical) change is found in many systems. The system size can be very different. The anti-lock braking system (ABS) is a mechatronic system. The brake itself is also one. And the control loop formed by driving control (for example cruise control), engine, vehicle driving speed in the real world and speed measurement is a mechatronic system, too.
Electronics and electricals
Electronics and telecommunication engineering specializes in electronics devices and telecom devices of a mechatronics system. A mechatronics engineer specialized in electronics and telecommunications have knowledge of computer hardware devices. The transmission of signal is the main application of this subfield of mechatronics. Where digital and analog systems also forms an important part of mechatronics systems. Telecommunications engineering deals with the transmission of
information across a medium.
Electronics engineering is related to computer engineering and electrical engineering. Control engineering has a wide range of electronic applications from the flight and propulsion systems of Airliner to the cruise control present in many modern cars (automobiles). VLSI designing is important for creating integrated circuits. Mechatronics engineers have deep knowledge of microprocessors, microcontrollers, microchips and semiconductors. The application of mechatronics in electronics manufacturing industry can conduct research and development on consumer electronic devices such as mobile phones, computers, cameras etc. For mechatronics engineers it is necessary to learn operating computer applications such as MATLAB and Simulink for designing and developing electronic products.
Mechatronics engineering is an interdisciplinary course, it includes concepts of both electrical and mechanical systems. A mechatronics engineer engages in designing Transformer or radio-frequency module transmitters.
Avionics
Avionics is also considered a variant of mechatronics as it combines several fields such as electronics and telecom with aerospace engineering. It is the subdiscipline of mechatronics engineering and aerospace engineering which is engineering branch focusing on electronics systems of aircraft. The word avionics is a blend of aviation and electronics. The electronics system of aircraft includes aircraft communication addressing and reporting system,
air navigation, aircraft flight control system, aircraft collision avoidance systems,
flight recorder,
weather radar and lightning detector. These can be as simple as a
searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform.
Industrial
The branch of industrial engineer includes the design of machinery, assembly and process lines of various manufacturing industries. This branch can be said somewhat similar to automation and robotics. Mechatronics engineers who works as industrial engineers design and develop infrastructure of a manufacturing plant. Also it can be said that they are architect of machines. One can work as an industrial designer to design the industrial layout and plan for setting up of a manufacturing industry or as an industrial technician to lookover the technical requirements and repairing of the particular factory.
Robotics
Robotics is one of the newest emerging subfields of mechatronics. It is the study of robots and how they are manufactured and operated. Since 2000, this branch of mechatronics is attracting a number of aspirants. Robotics is interrelated with automation because here also not much human intervention is required. In a large number of factories, especially in automobile factories, robots are found in assembly lines, where they perform the job of drilling, installation and fitting. Programming skills are necessary for specialization in robotics. Knowledge of programming language—ROBOTC—is important for functioning robots. 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.
Computer
The Internet of things (IoT) is the
Internetworking of physical devices,
Embedded system with
electronics,
software,
,
, and
Internet access which enable these objects to collect and exchange
data. IoT and mechatronics are complementary. Many of the smart components associated with the Internet of Things will be essentially mechatronic. The development of the IoT is forcing mechatronics engineers, designers, practitioners and educators to research the ways in which mechatronic systems and components are perceived, designed and manufactured. This allows them to face up to new issues such as data security,
machine ethics and the human-machine interface.
Knowledge of programming is very important. A mechatronics engineer has to do programming in different levels – for example, PLC programming, drone programming, hardware programming, CNC programming, etc. Due to combination of electronics engineering, soft skills from computer side is important. Important programming languages for mechatronics engineer to learn are Java, Python, C++ and C programming language.
Occupational outlook
According to the U.S. Bureau of Labor Statistics, the occupational outlook for mechatronics between 2016 and 2026 was 4% growth then declined to -4% for 2021 to 2031 then recovered to a -1% decline for 2023 to 2033. Currently their prediction for 2024 to 2034 is 1%.
