This document discusses mechatronics and provides examples of mechatronics systems. It defines mechatronics as the integration of sensors, actuators, control systems, and computers to manage complexity in engineered systems. Examples of mechatronics applications include consumer electronics, manufacturing systems like CNC machines, transportation systems like trains, robots, spacecraft, medical devices, defense technologies, smart home appliances, and more. Mechatronics combines mechanical engineering with electrical and computer engineering to create smart systems.

4. Mechatronics: Working Definition for
us
• Mechatronics is the synergistic integration of
sensors, actuators, signal conditioning, power
electronics, decision and control algorithms,
and computer hardware and software to
manage complexity, uncertainty, and
communication in engineered systems.
5. Elements of Mechatronics—
Electromechanical
• Electromechanical elements refer to:
– Sensors
• A variety of physical variables can be measured using sensors, e.g., light
using photo-resistor, level and displacement using potentiometer,
direction/tilt using magnetic sensor, sound using microphone, stress and
pressure using strain gauge, touch using micro-switch, temperature using
thermistor, and humidity using conductivity sensor
6. Cont.…
– Actuators
• DC servomotor, stepper motor, relay, solenoid, speaker, light emitting
diode (LED), shape memory alloy, electromagnet, and pump apply
commanded action on the physical process
• IC-based sensors and actuators (digital-compass, -
potentiometer, etc.).

7. Elements of Mechatronics—
Electrical/Electronic
• Electrical elements refer to:
– Electrical components (e.g., resistor (R), capacitor (C), inductor (L),
transformer, etc.), circuits, and analog signals
• Electronic elements refer to:
– analog/digital electronics, transistors, thyristors, opto-isolators,
operational amplifiers, power electronics, and signal conditioning
• The electrical/electronic elements are used to interface
electro-mechanical sensors and actuators to the control
interface/computing hardware elements
9. CNC Bending
Computer numerical control
•Fully automated bending: load
sheet metal and the finished bent
parts come out
•Can bend complex shapes

15. -Medical Applications-
•Used by patients with slow or
erratic heart rates. The pacemaker
will set a normal heart rate when it
sees an irregular heart rhythm.
•Monitors the heart. If heart
fibrillates or stops completely it will
shock the heart at high voltage to
restore a normal heart rhythm.
