The Following Special Formulation is Offered
Mechatronics studies synergistic fusion of precise mechatronical units, electronic, electro technical and computer components
for the purpose of designing and manufacturingqualitatively new
modules, systems, machines and complexes of machines
with intellectual control of their functional movements

Comments to the Definition
Mechatronics studies special conceptual approach toconstruction of machines.
The definition emphasizes synergetic character ofcomponents integration in mechatronic objects.
Integrated mechatronic components are always chosen at thedesigning stage.
Methods of parallel designing serve as methodological basisfor Mechatronic S ystems ( MS ) development.
The main objects that mechatronics studies are mechatronicmodules.
MS are intended to perform a set movement. In MS methods of advanced intelligent control are used to
secure high quality in performing precise movements.

Computer Control Device Basic Functions
Control of mechanical movement process on-line withcurrent sensor data analysis.
Arrangements to control MS functional movements.
Interaction with operator via human-machine interfaceoff-line and on-line interaction at the moment of MSmovement.
Data exchange between peripheral devices, sensors and
other devices of the system.

The Core of Mechatronic Approach
At the stage of designing one interface, as a separatedevice, is excluded out of a traditional structure, but
physical essence of transformation carried out by thismodule is kept.
in other words
It consists in integrating of components probably ofdifferent physical nature into a uniform functional module.

Basic Advantages in Comparison withTraditional Means of Automation
rather low cost; ability to perform complicated and precise movements
(of high quality);
high reliability, durability and noise immunity; constructive compactness of modules; improved overall dimension and dynamic characteristics
of machines;
opportunity to rebuild functional modules to sophisticatedsystems and complexes.

Career Paths in Mechatronics
mechatronics is seen as a prime career path formechanical engineers of the future;
mechanical engineers with a mechatronicsbackground will have a better chance of becomingmanagers;
classically trained mechanical engineers will run therisk of being left out of the interesting work.
