3. INTRODUCTION
 1969 -The ‘mechatronics’word introduced by
Tessturo Mori. He was a senior engineer of
Japanese company Yaskawa Electric Corporation.
 1971 – the company was granted the trademark
rights.
 1971- 80- mostly the servo technology is
used in mechatronics
 1981-90-IT introduced. Microprocessors were
embedded in Mechanical system.By K.BALAMANIKANDASUTHAN

4.  1991 -2000 – Communication technology was
added. Remoteoperation and roboticswere
developed .
 1996 – 1st journal IEEE on mechatronics was
released.
 After 2000, finds application in aerospace,
defence,
bio-mechanics, automotive electronics,
banking(ATM) etc.,

5. DEFINITION
Mechatronics is “ the synergistic integration of
mechanics and mechanical engineering,
Electronics, computer technology, and IT to
produceorenhance products and system”

16. Elements of mechatronics system
 Actuators andsensors
 Actuators – pneumatic & Hydraulic actuator,
electromechanical actuators, electrical motor suchas DC
motor, AC motor, stepper motor, servo motor & piezo
electricactuators
 Sensors – linear and rotational sensor, acceleration sensor,
force, torque and pressure sensor,temperature sensor,
proximity sensors, lightsensors
 Signals andconditioning
 Twotypes: input and output
 Input signal conditioning devices: discrete circuits,
amplifiers, analog to digital(A/D) convertors, Digitalto
Analog (D/A) convertors.
 Output signal conditioning devices: amplifiers,Digital to
Analog (D/A) convertors, display decoders (DD) convertors,
power transistors.

17. Elements of mechatronics system
 Digital logicsystems
 Logic circuits, micro controllers,
programmablelogic controllers(PLC),
sequencing and timing controls, control
algorithm.
 Software and data acquisitionsystems
 Data logger, computer with plug inboards
 Computers and displaydevices
 LED, CRT, LCD, digital displays etc.,

19. Control systems
A control system refers to a group of
physical component connected or
related in such a manner as to
command direct or regulate itself or
anothersystem.

21. TYPES OF CONTROL SYSTEM
Open loop control system
Closed loop or feedback control
system
By K.BALAMANIKANDASUTHAN
AP/MECHVELAMMAL ITECH

22. Open loop control system
Open loop system are systems in which theoutput
of a system is not used as a variable to control the
system.
By K.BALAMANIKANDASUTHAN
AP/MECHVELAMMAL ITECH

23. Element of open loop controlsystems
Bread toaster (open loop ) controlsystem

24. Closed loop control system
Closed loopsystem useson a feed back loop tocontrol
the operation of thesystem.

25. Room heating (Closed loop) control system
By K.BALAMANIKANDASUTHAN
AP/MECHVELAMMAL ITECH

26. Open loopsystem
 It does not usesfeedback
 It is lessaccurate
 It is simplein
construction
 The response is slow
because manualcontrol
 Easy maintenance
because of nocomplex
electroniccircuit
 Cost is less
Closed loopsystem
 It uses feedbacksystem
 It is moreaccurate
 It is complicated in
construction
 It perform task faster
than open loop
 It is difficult tomaintain
and repair
 Cost is more
By K.BALAMANIKANDASUTHAN
AP/MECHVELAMMAL ITECH

27.  What is the function of
Sensors?
 How does Open loop
system differ from Closed
Loop System?
 Say Few example for
Closed loop system. By K.BALAMANIKANDASUTHAN
AP/MECHVELAMMAL ITECH

28. Emerging areas of mechatronics
 Development of unmannedvehicles
 Design of subsystem forautomotiveengineering
 Expert system and artificialintelligence
 Medical mechatronics and medical imaging systems
 Micro/Nano Mechatronics
