INTRODUCTION AUTOMATED SYSTEMS LIKE ROBOT

CARRY OUT SPECIFIC TASKS.

THESE SYSTEMS ARE USUALLYEMPLOYED IN ENVIORNMENTS WHERECONDITIONS KEEP CHANGING.

THE ROBOT BEING DESCRIBED HERESENSES 38khz INFRARED RADIATIONAND MOVES TOWARDS THAT DIRECTION.

HOW IT ACTUALLY WORKS BASICALLY AS THE POWER IS SWITCHED

ON THE THREE 555 TIMER ICS PRODUCE

A 38KHZ INFRARED RADIATION.THESETHREE SENSORS HAVE BEEN PLACED ATLEFT ,RIGHT,FRONT OF THE CAR.

UNTILL AND UNLESS THE INFRARED

RAYS FROM THE IR LED DONT FALL ON

THE TSOP ATTACHED NO DATA ISFORWARDED TO THE CONTROLLER .

CONTINUATION

BUT WHENEVER A OBSTACLE IS ENCOUNTERED THEIR RAYS ARE REFLECTED BY IT AND ARE RECEIVED BYTHE TSOP.

THE VOLTAGE ON CONTROLLER PIN GOES LOW ANDRELAY IS SWITCHED ON USING ULN-2804.

PROBLEMS ENCOUNTERED

THE MOST BASIC PROBLEM WAS THATOF EFFICIENT UTILIZATION OFRESOURCES.

ANOTHER IMPORTANT BASIC TO BEKEPT IN MIND IS REGARDINGSOLDERING.REMEMBER:EXCESS OFSOLDER AND LOOSE CONNECTIONS ARENOT WELCOMED.

THE MOST IMPORTANT PROBLEM IN ANYMECHANICAL BASED PROJECT IS THEMANUAL SETTINGS TO BE DONE.


8/15

TROUBLESHOOTINGTHE MOST IMPORTANT PART OF ANY PROJECT ISTHAE PART OF TROUBLESHOOTING THAT PROJECT.

FOR MY PROJECT TWO MOST KEY THINGS WERE

MY PATIENCE AND PERSEVERANCE THAT PROVED

INDEPENSIBLE.

FOR MY PROJECT THE TROUBLE SHOOTING

INCLUDED SETTING THE SENSORS AND MAKING

THE RELAYS ON ACCORDING TO THE SENSOR

ACTION.

HERE I WOULD LIKE TO TELL YOU THAT WHOLE

OF THE FACULTY AT THE HARDWARE LAB HELPED

ME A LOT.


9/15

TECHNOLOGY PLATFORM

WELL EVERYTHING ABOUT ANY PRODUCT OR IT BE

ANY PROJECT DEPENDS UPON THE TECHNOLOGY

BEING USED.TEHNOLOGY HAS TOUCHED NOT ONLY

OUR INDUSTRIES BUT ALSO OUR DAY TO DAY LIFE.

AS FAR AS TECHNOLOGY USED IN MY PROJECT IS

CONCERNED ITS BASICALLY ,WHAT WE ALL KNOW BY

THE NAME OF EMBEDDED SYSTEMS.

EMBEDED SYSTEMS

An embedded system is a special-purpose computer system

designed to perform a dedicated function. Unlike a general-

purpose computer, such as a personal computer, an embedded

system performs one or a few pre-defined tasks, usually withvery specific requirements, and often includes task-specific

hardware and mechanical parts not usually found in a general-

purpose computer. Since the system is dedicated to specific

tasks, design engineers can optimize it, reducing the size and

cost of the product. Embedded systems are often mass-

produced, benefiting from economies of scale.

11/15

Physically, embedded systems range from portable

devices such as digital watches and MP3 players, to

large stationary installations like traffic lights,

factory controllers, or the systems controlling

nuclear power plants. In terms of complexityembedded systems run from simple, with a single

microcontroller chip, to very complex with multiple

units, peripherals and networks mounted inside a

large chassis or enclosure.

Mobile phones or handheld computers share some

elements with embedded systems, such as the

operating systems and microprocessors which power

them, but are not truly embedded systemsthemselves because they tend to be more general

purpose, allowing different applications to be loaded

and peripherals to be connected.

APPLICATIONS

THE ROBOT CAN BE USED AS APROTOTYPE TO THE DEVELOPMENT OF

MANY OTHER SUCH USEFUL PRODUCTS.

WITH A SLIGHT MODIFICATION THE

ROBOT CAN BE USED AS A FIRE FIGHTING

ROBOT.

IT CAN ALSO BE USED AS HEAT TRACKING

MISSILE ROBOT.

A WORD OF THANKS

NO WORK CAN EVER BE

COMPLETE WITHOUT SHEER

DETERMINATION AND PATIENCE

AND HARDWORK.BUT BESIDES

THESE VIRTUES THERE IS A

GOLDEN KEY THAT HELPS TO

UNLOCK GATES OF

SUCCESS.ANHD THAT IS A GOOD

GUIDANCE,A GOOD

MENTOR,AND A PERSON WHOINSPIRES YOU AT EVERY STEP.

MY SPECIAL THANKS TO ALL

FACULTY MEMBERS AND

MYFRIENDS AT EMTECH

FOUNDATION,WHO HELPED ME

IN ACHIEVING WHAT I HAVE.
