INTRODUCTION

D.U.G.I compaX??? What isD.U.G.I compaX..??D.U.G.I compaX is the acronim for

Durable. Universal. Generated. Innovation. Nowadays, most of the people in the world are busy to

manage their time to solve their house chores , the problem is most people in the world experience

serious problem which is the problem of cleaning the house . This can be proved by surveys that have

been made available 18 out of 20 respondents (90%) saying that they do have housecleaning

problem.Another minor factor is housewives will feel tired after cleaning their house and eventually

they dont have time to spend time with their family. Because of these factors, This World need a

robot which could clean the house itself without the aid of housemaids. So, using robotic principles

and systems, we can solve the household problems in a conventional way . "ROBOT FOR LIFE

Improvement" is the theme in the category that we took part. The robot that we created is very

precise according to the requirements in this category.

To overcome these problems, a robot that can help human when facing problems of

cleaning the house is made by us Hafizi and Haris. The D.U.G.I compaXrobot can MOP, VACUUM,SWEEP, AIR FRESHENER and SPRAY pesticides.

PROBLEM STATEMENT

Vacuum cleaners ( an electrical household appliance used for cleaning floors, carpets and furniture) are

widely used all over the world. But we never heared about multifunction vacuum cleaner. ROBOT

FOR LIFE IMPROVEMENT helped our team to generate new ideas to create a futuristical

housekeeping robot. The vacuum cleaner is used to suck dust or things such as stapler bullets or

small bits of papers. We made the vacuum cleaner by using zinc that could be shaped easily.

As we all know, mopping stands for household implement made of absorbent material

attached to a typically long handle and used for washing, dusting, or drying floors. It could be a burden

to the housewive to do their house work. Our robot is also built in with a mopping system as if it was a

human being. Its amazing right?

This robots novelty is when it encounters dark places that are usually hard to reach, there

must be something living under there or on the other hand insects mainly pests such as cockroaches.

Do you know what our robot could do? Our robot could spray the dark places such as underneath a

closet or low shelf etc. and eventually kill the pests such as mosquitoes and cockroaches.

The conclusion is, by using this robot, all the household work like vacuum cleaning,fill the

house with harmonical odour, sweep, mopping the floor and spray pests are solved and eventually to

make our life more relax.

DESIGN PRINCIPLE

There are 5 main funtion on the robot 1st

Vacuum Cleaner, 2nd

Mopping System, 3rd

Insects Spray, 4th

Sweep, and lastly 5th

Air Freshener.

1) Vacuum Cleaner

Used to suck dust on the floor of the house properly

Made from zink pieces so that easily to

shape.

Uses 4 computer fans to increase the

ability of vacuum to suck dust.


5/16


2) Mopping system

During the vacuuming session, mopping system automatically launch as we had programmed

2 sponges are used in mopping system.

It is located at the rear of the robot.

2 motor are used to spin in the opposite

direction of the sponges


6/16


3) Insects Spray

The robot will spray the places that are in dark condition with low light intensity

The spraying system will be generated when the robot encounters dark places such as under

the table, cupboard and bed.

The spray will operate when the light intensity is low by using the Light sensor.


7/16


Lego Mindstorm operating system

1st

NXT

Control the movement of robot.

Control the movement of the robots left wheel and right wheel.

The NXT port used are port B and port C.

2ND

NXT

Used to operate the spraying mechanism by connecting it to Light Sensor.

The control center for the sensors namely ultrasonic sensor,touch sensor and light sensor

The NXT port used are port B and C.


8/16


3rd

NXT

Used to operate the brushing mechanism and the mopping system.

The Brushing System and the Mopping System are operated continuously when the robotstarts.

The NXT port used are port A and B.

SPECIAL FUNCTION


9/16


Sweep Brush Sweep the dust and channels it into the vacuum cleaner.

Ultrasonic Sensor

Located at in the front left of the robots body To detect distance from the robots body to lower floors

such as stairs and prevents the robot from dropping and

damaging the robot

Water Storage tank

Storage of soap water that is used for the mopping

Mechanism. 2 containers are used in this system( as a water container to

hold water which will be channeled by the

water pump in this Mopping System).

Light Sensor

Detect the light intensity in dark place so that the spraying

mechanism can operate.

Air fresheners (Air Wick)

A pair of Air Fresheners are used at left side and right side

of the vacuums fans.

To fill the house with harmonical odour such as Lavender,

Apple, and Lemon.


10/16


Rubber wiper

Used to dry the water made by the mopping system.

Locate at the rear of the D.U.G.I COMPAX robot

Main tyre

4 tyres are used and each 2 tyres willbe controlled by one

motor.

To control the movement of the robot.

Supporter Wheels

3 supporter wheels are used in this robot.

To support the weight of the robot which is 2.6 KG.

12 Volt Batteries

For this robot, a pair of 12 Volts batteries are used to

operate 4 fans of the Vacuum Cleaner.
