Microprocessor
•CPU is stand-alone, RAM,
ROM, I/O, timer are separate
•designer can decide on the
amount of ROM, RAM and
I/O ports.
•expansive
•versatility
•general-purpose
Microcontroller
•CPU, RAM, ROM, I/O and
timer are all on a single chip
•fix amount of on-chip ROM,
RAM, I/O ports
•for applications in which cost,
power and space are critical
•single-purpose

10. Sensors and Actuators
•Sensor
A device that converts an environmental condition into an
electrical
signal.
•Actuator
A device that converts a control signal (usually electrical) into
mechanical action (motion).
(Taken together, sensors, actuators, controllers, and power supply
form
the basic elements of a control system.)

12. The Following Special Formulation is Offered
Mechatronicsstudies synergistic fusion of precise
•mechatronical units,
•electronic,
•electro technical and computer components
for the purpose of designing and manufacturing qualitatively
new
•modules,
•systems,
•machines and complexes of machines
with intellectual control of their functional movements

13. Comments to the Definition
•Mechatronics studies special conceptual approach to construction of
machines.
•The definition emphasizes synergetic character of components’
integration in mechatronic objects.
•Integrated mechatronic components are always chosen at the
designing stage.
•Methods of parallel designing serve as methodological basis for
Mechatronic Systems (MS) development.
•The main objects that mechatronics studies are mechatronic modules.
•MSare intended to perform a set movement.
•In MSmethods of advanced intelligent control are used to secure
high quality in performing precise movements.

14. Principles of

machine
e.g.: cutting forces for machining processes,
contact forces and moments of forces at assembly,

15. Examples of Mechatronic Systems

computer disk drive

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

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

18. Basic Advantages in Comparison with
Traditional 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 sophisticated
systems and complexes.

19. Modern Trends of MS Development
•Office equipment;
•Computer facilities;
•Photo and video equipment;
•Machine-tool construction and
equipment for automation of
technological processes;
•Robotics;

20. Modern Trends of MS Development
•Aviation, space and
military techniques;
•Motor car constructor;

21. Modern Trends of MS Development
•Micro machines;
•Control and measuring devices and machines;
•Simulators for training of pilots and operators;
•Show-industry;
•Non-conventional vehicles.

22. Requirements of the World Market
in the Considered Area
•Standard ISO 9000;
•Necessity for active introduction of forms and methods of
international engineering and putting new technologies into
practice;
•Increasing role of small and average industrial enterprises in
economy owing to their ability to quick and flexible reaction
to changing requirements of the market;
•Intellectualization of mechanical movement control systems
and technological functions of modern machines.

23. Fundamental Problems
•Structural integration of mechanical, electronic and
information departments into a uniform creative staff;
•Education and training of engineers specialized in
mechatronics and managers able to organize integration and
supervise work of strictly specialized experts with different
qualifications;
•Integration of information technologies from various scientific
and technical fields into a uniform toolkit to provide computer
support of mechatronic problems;
•Standardization and unification of all used elements and
processes at designing and manufacturing MS.

24. Levels of Mechatronic Systems’Integration
The First Level
•conveyors,
•rotary tables,
•auxiliary manipulators

25. Levels of Mechatronic Systems’Integration
•operated power machines (turbines and generators),
•machine tools and industrial robots with numerical
program management
The Second Level

26. Levels of Mechatronic Systems’Integration
Synthesis of new precise, information and
measuring high technologies gives a basis for
designing and producing intellectual mechatronic

27. Career Paths in Mechatronics
•mechatronics is seen as a prime career path for mechanical
engineers of the future;
•mechanical engineers with a mechatronics background will
have a better chance of becoming managers;
•classically trained mechanical engineers will run the risk of
being left out of the interesting work.
