Introduction

• Mechatronics - is synergistic integration of
  mechanical engineering, electronics and
  intelligent computer control in design and
  manufacture of products and processes.

3

• Mechatronics basically refers to mechanical,
  electrical systems and is centered on mechanics,
  electronics, computing and control which,
  combined, make possible the generation of
• simpler,
• more economical,
• reliable and versatile systems.
• The term "mechatronics" was first assigned by
  Mr. Tetsuro Mori, a senior engineer of the
  Japanese company Yaskawa, in 1969.

Common examples of mechatronic Devices

• Domestic Devices
• Microwaves, bread makers, washing machines, CD
  players, VCRs ... etc.
• Industrial
• CNC machine tools, active magnetic bearings,
  active noise suppression system, mobile robots
  ... etc.
• Automotive
• ABS, fuel/Ignition/emission controls, climate
  control, cruise control ... etc.

Assume
For example, in a modern car the electronics and
control play a dominant role (up to 50), whereas
a car from the seventies and even early eighties
was nearly purely mechanical (90).
14
Manufacturing Applications
CNC Bending

• Fully automated bending load sheet metal and the
  finished bent parts come out
• Can bend complex shapes

• Advantages
• Deliver the highest accuracies
• Can create very complex shapes

15
Transportation Applications
Automobiles

• Typical Applications
• Brake-By-Wire system
• Steer-By-Wire
• Integrated vehicle dynamics
• Camless engines
• Integrated starter alternator

• Advantages
• Reliability
• Reduced weight
• Fuel economy
• Manufacturing flexibility
• Design freedom
• Advanced safety features
• Cost

16
Transportation Applications
High Speed Trains

• Train Position and Velocity constantly monitored
  from main command center.
• Error margin in scheduling no more than 30
  seconds

Cleans Gutter
21
Space Exploration Applications
Phoenix Mars Lander's

• System Can
• Collect specimens
• Has automated onboard lab for testing specimens

• Advantages
• Robot that can travel to other planets and take
  measurements automatically.

22
Medical Applications
Prosthetics

• Arms, Legs, and other body parts can be replaced
  with electromechanical ones.

23
Medical Applications
Pace Maker

• Used by patients with slow or erratic heart
  rates. The pacemaker will set a normal heart rate
  when it sees an irregular heart rhythm.

Implantable Defibrillation

• Monitors the heart. If heart fibrillates or
  stops completely it will shock the heart at high
  voltage to restore a normal heart rhythm.

24
Defense Applications
Stealth Bomber

• Advanced technology is making our soldiers safer.
• Some planes can now be flown remotely.
