 The term mechatronics was ‘invented’ by a Japanese engineer in 1969, as a
combination of ‘mecha’ from mechanisms and ‘tronics’ from electronics.
 Mechatronics: is the synergistic integration of mechanical engineering with
electronics and intelligent computer control in the design and manufacture of
products and processes.
 Mechatronic products have many mechanical functions replaced with
electronic ones for much greater flexibility, easy redesign & reprogramming,
and the ability to carry out automated data collection & reporting.

 Robotics: is a large, extremely multidisciplinary field:
 Path Planning
 Computer Vision
 Mechanical Design
 Controls
 Dynamics
 Human-Robot Interface
 Mechatronics
 Mechatronics: is an integral element of robotics dealing with hardware-
software integration.
 Implementation of robotic systems cannot be accomplished without
mechatronics.

 While all robots are mechatronic devices in some form, not all mechatronic
devices are robots.
 Many mechatronic devices lack the intelligence, self-initiative, decision-
making, and adaptability inherent in many robotic devices.

 When designing mechatronic devices, it is critical to balance engineering
analysis and hardware experimentation appropriately.
 Failure to use engineering analysis tools to appropriate extent can lead to:
 Excessive Development Time
 Poor System Performance
 Failure to Achieve System Objectives

 Mechatronics design process is important to follow, even for simple systems
 Can save time, money & effort
 “Trial & Error” methods used often by beginners may work for simple
systems but will be unacceptably costly when developing complex devices
