Study Notes

Mechatronics Introduction

Mechatronics is a multidisciplinary field combining mechanical engineering, electronics, computer engineering, telecommunications engineering, systems engineering, and control engineering.
It's a multidisciplinary approach to product and manufacturing system design.
The term "Mechatronics" was coined by Mr. Tetsuro Mori of Yaskawa in 1969.
"Mechatronics" was registered as a trademark by Yaskawa in Japan with registration number 46-32714 in 1971.
Mechatronics is a synergistic integration of mechanical engineering, electronics, and intelligent computer control in designing and manufacturing products and processes.

Components of a Mechatronics System

Actuators: These produce movement or action, examples include DC motors, stepper motors, servomotors, hydraulics, and pneumatics.
Sensors: Sensors detect the state of system parameters (inputs and outputs). Examples include switches, potentiometers, strain gauges, thermocouples, and digital encoders.
Input signal conditioning and interfacing: Connect control circuits to inputs. Includes discrete circuits, amplifiers, filters, A/D and D/D converters.
Digital control architectures: Control the system using logic circuits, microcontrollers, and programmable logic controllers (PLCs).
Output signal conditioning and interfacing: Connect outputs to control circuits. Includes D/A, D/D converters, amplifiers, and power transistors.
Graphical Displays: Provide visual feedback to users, including LEDs, LCDs, digital displays, and CRTs.

Levels of Mechatronics Systems

Primary Level: Integrates electrical signaling with mechanical action at the basic control level (e.g., fluid valves and relay switches).
Secondary Level: Integrates microelectronics into electrically controlled devices (e.g., cassette tape players).
Tertiary Level: Incorporates advanced control strategies using microelectronics, microprocessors, and application-specific integrated circuits. Examples include robots and large factory systems.
Quaternary Level: This level aims to enhance the system's "smartness" by adding artificial intelligence (e.g., neural networks, fuzzy logic), fault detection, and isolation.

System Definition

A system is a group of physical components working together to perform a specific function. Mechatronics devices consist of systems.
A system can be viewed as a "black box" with inputs and outputs.
A control system manages the system's output to a desired value (e.g., domestic air conditioning).

System Examples

Motor: Input=electric power; Output = rotation
Electric Generator: Input =mechanical rotation; Output =electric power
Spring: Input =force; Output =extension
Thermometer: Input =temperature; Output =numerical reading
