Specially dedicated to my dearest mom, Che Azma Binti Che Ishak and dad,
Nik Abd Halim Bin Nik Yussof, my sister Nik Farhanim , my brother Nik Hafizzi and all
my fellow friends,
who have encouraged, guided and inspired me throughout my journey of education.

ACKNOWLEGMENT

First and foremost, I would like to thanks ALLAH s.w.t. because of HIM I’m
here standing and able to complete my project. I also take this opportunity to express my
deepest gratitude towards my project supervisor, En Mohd Shahrieel Bin Aras who has
persistently and determinedly assisted me this project. It would have been very arduous
to complete this project without the passionate supports and guidance encouragement
and advices given by him. My outmost thanks also go to my family who has given me
support throughout my academic years. Without them, I might not be able to become
who I am today. I am grateful to have love affection and care from all of my family
members as well. My fellow friends should also be recognized for their continual
support and encouragement. My sincere appreciation also extends to my entire course

mate and others who have provided assistance at various occasions. Their views and tips
are useful indeed Last but not least, thanks to individuals that has contributed either
directly or indirectly to make this thesis project. Without all these people helps,
encouragement, support, advices, this thesis project might not be successfully carried
out. Of course, as is usual, all errors and oversights are entirely my own. Thanks you
once again.

ABSTRACT

The development of mobile robots has become popular among inventor
nowadays. In many applications multi robot systems are desirable for much reason. In
the case of planetary explorers, deploying more robots will enable coverage of large area
in a shorter time. Like ants and other insects, many cheap robots working together could
replace a single expensive robot, making a multi robot system more cost effective. Multi
robot systems can accomplish task that no single robot can accomplish, since ultimately
a single robot, no matter how capable, is spatially limited. In this project, i-MS will be
developed with two unit mobile robots as multi agent robot system that can perform
team movement in interacted with the environments. Multi agent mobile robots as

master-slave is able to move automatically on flat surfaces which it has ability of
obstacle avoidance where it will try to avoid collision for object that come in its way.
The robots will be controlled by PIC16F877A microcontroller. As for the software part,
there are two main of software development tools being used in building the multi agent
robot intelligence. There are the MPLAB Integrated Development Environment (IDE)
and PICC LITE. Two units of RC Servo Motor (C36R) are used as actuator for each
robot. KC Wirefree Bluetooth Module KC21 is used as communication method among
the robots which will allow master-slave behaviors. One of the robots will act as master
whiles another one as slave. The slave will follow the movement of master. The robots
have interchanging masterslave function based on environment.

ABSTRAK

Semenjak akhir-akhir ini, penciptaan mobile robot menjadi semakin popular di
kalangan pencipta robot. Dalam banyak aplikasi, multi robot sistem sangat diperlukan
untuk beberapa perkara yang tertentu. Dalam kes penjelajahan planet, dengan
meletakkan beberapa robot akan membolehkan kawasan yang luas di litupi dalam masa
yang singkat. Seperti semut dan juga serangga yang lain, dengan meletakkan beberapa

robot murah yang boleh bekerjasama antara satu lain bagi menggantikan robot yang
mahal, ini menghasilkan sistem multi robot yang effektif. Multi robot boleh melakukan
kerja yang tidak boleh dilakukan oleh single robot kerana walaupun single robot
berkeupayaan tinggi tetapi rekabentuknya adalah terhad. I-MS, boleh dibangunkan
dengan dua robot dimana agen multi robot boleh melakukan pergerakan mengikut
persekitaran secara berkumpulan. Multi agent robot yang bertindak sebagai master boleh
bergerak secara automatic di atas permukaan rata dan berkeupayaan untuk mengesan
halangan di mana ia akan cuba untuk mengelak daripada berlakunya kemalangan. Robot
ini dikawal dengan menggunakan PIC 16F877A mikropengawal. Pada bahagian
software, terdapat 2 bahagian utama dalam membagunkan multi robot yang pintar ini.
Software yang digunakan adalah MPLAB Integrated Development Environment (IDE)
dan PICC LITE, dua unit RC Servo Motor (C36R) digunakan sebagai actuator untuk
setiap robot. KC Wirefree Bluetooth Module KC21 digunakan sebagai peranti
perhubungan di antara robot di mana ia akan mengikut perlakuan master-slave. Satu
robot akan bertindak sebagai master dan satu robot akan bertindak sebagai slave. Robot
slave akan mengikuti pergerakan robot master. Fungsi master-slave bagi robot akan
bertukar bergantung kepada persekitaran.
