Mechatronics History / Origin
1969 in Japan, Tetsura Mori, a senior engineer of Yaskawa
Electric Corp., coined the term “Mechatronics“.
The word ‘Mechatronics’ composed of MECHAnics and
elecTRONICS.
In the 1980s, mechatronics was used to focus on information
technology whereby microprocessors were embedded into
mechanical systems to improve performance, such as antilock
braking and electric seats.
In the 1990s, mechatronics centered on communication
technology to connect products into large networks, including
the production of air bags and other related technologies.

Mechatronics Definition
Mechatronics is the synergistic combination of
precision mechanical engineering, electronic
control and systems thinking in the design of
products and manufacturing processes.
Mechatronics is a methodology used for the
optimal design of electromechanical products.

Mechatronics Simulation & Modeling
Modeling is the process of representing the
behavior of a real system by a collection of
mathematical equations and logic.
Simulation is the process of solving the model
and is performed on a computer.
The process of simulation can be divided into
three sections:
Initialization
Iteration
Termination

Mechatronics Optimization
Optimization solves the problem of distributing
limited resources throughout a system such that
prespecified aspects of its behavior are satisfied.
In mechatronics, optimization is primarily used to
establish the optimal system configuration.
Resources….Design variables
System behaviour …… Objectives
System relationship …..Constraints

Mechatronics Advantages
Cost effective and very good quality product.
High degree of flexibility.
Greater extent of machine utilization.
Capital expenses are reduced.
Owing to the incorporation of intelligent, self
correcting sensory and feedback systems, the
mechatronic approach results in:
Greater productivity;
Higher quantity and producing reliability.
A Textbook of Mechatronics, R K Rajput
Mechatronics Disadvantages
High initial cost of the system.
Imperative to have knowledge of different
engineering fields for design and implementation.
Specific problems for various systems will have
to be addressed separately.
It is expensive to incorporate mechatronics
approach to an existing / old system.
