This document defines mechatronics and provides an overview of its origin, design, applications, and examples. Mechatronics is defined as the synergistic combination of precision engineering, electronics, and systems thinking in product and process design. The term was coined in 1969 by a Japanese engineer. Examples of mechatronic systems include home appliances, robots, vehicles, and the Phoenix Mars lander. The document discusses designing mechatronic systems and replacing mechanical parts with electronic components and sensors. It lists applications and provides brief descriptions of robots and the Phoenix mission.

3. “Mechatronics is the synergistic
combination of precision mechanical
engineering, electronic control and
systems thinking in the design of
products and manufacturing processes.”
Example:
Use of Home appliances, toys…..etc.
“The portmanteau ‘Mechatronics was
coined by Ko Kikuchi, the senior
engineer of the Japanese company
Yasakawa in 1969.”

5. Origin of Mechatronics:
 Technological advances in
design, manufacturing and
operation of engineered
products/devices /processes
can be traced through:
o Industrial revolution.
o Semiconductor revolution.
o Information revolution.

6. DESIGN OF MECHATRONIC SYSTEM:
 Replacement of Mechanical part by Electronic
component like piezo electronic actuator.
 Replacing Analogue measurement system for
inputs by sensors.
 Instead of using bimetallic temperature switches, a
micro processor based thermo diode sensors can
do on/off function.
 Mechatronics approach has redefined and accurate
result output as compared to crude and inaccurate
readings of traditional analogue systems with
mechanical design in total.

7.  Automation and Robotics.
 Servo Machines.
 Automotive Engineering E.g.: anti lock braking system.
Expert Systems.
 Industrial goods.
 Transportation and vehicular systems.
 Mobile applications.

8. Phoenix:
o Phoenix was a robotic
spacecraft on a space
exploration mission
on Mars under the Mars
Scout Program.
The Phoenix Lander des
cended on Mars on May
25, 2008. Mission
scientists used
instruments aboard the
Lander to search for
environments suitable
for microbial life on
Mars, and to research
the history of water
there.

9. ROBOTS:
 A Robot is a mechanical or virtual intelligent agent
that can perform tasks automatically or with
guidance typically by a remote control.
 It is usually an electro mechanical machine that is
guided by computer and electronic programming.
E.g.: NAO, ASIMO, TOPIO.
