Mechatronics - The Future is Now

Traditionally, the two most difficult majors are Mathematics and Physics. This field, which relies on both, may eclipse them both. A PhD in Mechatronics, which grew out of Robotics yet grew larger such that Robotics is a mere part of it, will be the equivalent of 4-6 PhDs, and not in easy disciplines.

The future is coming. The future is now.

From Wikipedia:

 is the combination of mechanical engineeringelectronic engineeringcomputer engineeringsoftware engineeringcontrol engineering, and systems design engineering in order to design, and manufacture useful products[1][2]. Mechatronics is a multidisciplinary field of engineering, that is to say it rejects splitting engineering into separate disciplines. Originally, mechatronics just included the combination between mechanics and electronics, hence the word is only a portmanteau of mechanics and electronics. However, as technical systems have become more and more complex the word has been "updated" during recent years to include more technical areas.
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".



Aerial Venn diagram from RPI's website describes the various fields that make up Mechatronics
A mechatronics engineer unites the principles of mechanics, electronics, and computing to generate a simpler, more economical and reliable system. Mechatronics is centered on mechanicselectronicscomputingcontrol engineeringmolecular engineering (from nanochemistry and biology), and optical engineering, which, combined, make possible the generation of simpler, more economical, reliable and versatile systems. The portmanteau "mechatronic" 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, mechanical , 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 hierarchypolyarchy,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 every-day equipment such as autofocus cameras, video, hard disks, and CD players.

[edit]Course structure

Mechatronic students take courses from across the various fields listed below:
  • Mechanical engineering and materials science subjects
  • Electronic engineering subjects
  • Computer engineering subjects
  • Computer science subjects
  • Systems and control engineering subjects
  • Optomechanics (optical engineering) subjects
  • Robotics subjects


[edit]Physical implementations

For most mechatronic systems, the main issue is no more how to implement a control system, but how to implement actuators and what is the energy source. Within the mechatronic field, mainly two movement: the piezo-electric actuators and motors, or the electromagnetic actuators and motors. Maybe the most famous mechatronics systems are the well known camera autofocus system or camera anti-shake systems.
Concerning the energy sources, most of the applications use batteries. But a new trend is arriving and is the energy harvesting, allowing transforming into electricity mechanical energy from shock, vibration, or thermal energy from thermal variation, and so on.

[edit]Variant of the field

An emerging variant of this field is biomechatronics, whose purpose is to integrate mechanical parts with a human being, usually in the form of removable gadgets such as an exoskeleton. Such an entity is often identified in science fiction as a cyborg. This is the "real-life" version of cyberware.
Another emerging variant is Electronical or electronics design centric ECAD/MCAD co-design. Electronical is where the integration and co-design between the design team and design tools of an electronics centric system and the design team and design tools of that systems physical/mechanical enclosure takes place.
