MECHATRONICSAN INTRODUCTION

SHIVAJI CHOUDHURY

MECHATRONICS YASAKAWA ELECTRIC,JAPAN, INTRODUCED THE TERM

“MECHATRONIC” IN 1969.

INITIALLY MECHATRONICS REFFERED TO SYSTEM WITH ONLY MECHANICAL SYSTEM AND ELECTRICAL COMPONENTS , NO COMPUTATION WAS INVOLVED .

EXAMPLE INCLUDE THE AUTOMATIC SLIDING DOOR,VENDING MACHINE,GARAGE DOOR OPENER.

WHAT IS MECHATRONICS ? MECHATRNICS IS SYNERGISTIC INTEGRATION OF

MECHANICAL ENGINEERING ,ELECTRONICS,CONTROL AND COMPUTER.ALL INTEGRATED THROUGH THE DESIGN PROCESS.

EXAMPLE- -ROBOT,PHOTOCOPIER,DISK DRIVE.

MECHATRONICS

BENEFITS OF MECHATRONICS

ENHANCED FEATURED AND FUCTIONALITY. MORE USER FRIENDLY PRECISION CONTROL MORE EFFICIENT LOWER COST. FLEXIBLE DESIGN( REPROGRAMABLE) SAFE SMALLER

EXAMPLES

1. PRIMARILY MECHANICAL PRODUCTS WITH ELECTRONICS INCORPORATED TO ENHANCE FUNCTIONALITY e g. NUMERICAL CONTROLLED MACHINES TOOLS.

2. TRADITIONAL MECHANICAL SYSTEM WITH SIGNIFICANTLY UPDATED INTERNAL DEVICES INCORPORATING ELECTRONICS e g THE MORDEN SEWING MACHINE.

TRUE MECHATRONICS1. THE PRODUCTS DESIGNED WITH MECHANICAL

AND ELECTRONICS TECHNOLOGIES THROUGH SYNERGITIC INTEGRATION e g PHOTOCOPIER MACHINE.

2. WITH THE DEVELOPMENT OF MICROPROCESSORS BY INTEL,INTEGRATION OF COMPUTATIONAL SYSTEMS WITH MECHANICAL SYSTEM BECOME PRACTICAL.

3. THE MICROPROCESSOR IS THE HEART OF MORDEN MECHATRONICS AND SMART PRODUCTS
