MECHATRONICS
DEFINITIONS OF MECHATRONICS
• The word Mechatronics was first coined by
Mr. Tetsuro Moria, a senior engineer at Japanese company
Yaskawa in 1969
• It simply means applying electronic control to mechanical
components
• It is the Synergistic integration of all branches of
engineering
• Simultaneous / concurrent approach
Eg: e – Manufacturing
e – Welding
e – Casting
Industrial robots
Modern fuel injection systems

Classification of Mechatronic system
Mechatronic systems can be classified based on their control architecture and
elements
The common control architectures include
i) Hierarchy
ii) Polyarchy
iii) heterarchy and
iv) hybrid
Elements in typical mechatronic systems include:
• Actuators and sensors
• Signals and conditioning
• Digital logic systems
• Software and data acquisition systems
• Computers and Display devices
1.Hierarchy: This is a structured approach where control is organized in levels, with
higher levels setting goals and constraints for lower levels. It’s commonly used in
systems like aerospace and industrial automation.
2. Polyarchy: In this architecture, control is distributed among multiple controllers
without a strict hierarchy. This can enhance flexibility and adaptability but may
require more sophisticated coordination mechanisms.
3. Heterarchy: This approach allows for more decentralized control, where different
parts of the system can operate independently or collaboratively as needed. It’s
often used in robotics and networked systems.
4. Hybrid: This combines elements of hierarchical and heterarchical architectures to
leverage the benefits of both. It can provide a balance between centralized control
and decentralized flexibility.
Each architecture has its strengths and is chosen based on the specific requirements
and constraints of the system being controlled.
