Engineering with specialization in Control Engineering. My graduation thesis’
title is “Design and Implementation of External Communication Module between
Mobile Robots. I’ve also involved in research during my exchange program in Japan that has
the title “Developing Micro Robots using Hopping Locomotion Principle”

final year project deals with the design
and implementation of external communication module between mobile robots.
The movement type that is used is differential steering movement type.

external communication module is attached at the back of mobile robot. This
external communication module is based on radio frequency. The advantage of
radio frequency is this method using wireless technology that is more practical
that wired technology

function of this external communication module is for the communication between
mobile robots such that the mobile robots can exchange data. This data is the
state of the sender mobile robot that represents distance and orientation of
that mobile robot.

experiment is done by sending the state of the sender mobile robot as 3-bit
data, 5-bit data, and 7-bit data for several distances. The distance that is
chosen is 2 meters, 4 meters, and 6 meters.

results showed that external communication between mobile robots is working
well, with results of 3-bit, 5-bit, and 7-bit data sending that represents
mobile robot sender’s state for 2 meters, 4 meters, and 6 meters had data error
0%, except for the first try of sending 5-bit data with 6 meters distance there
is 17% of data error. For the application in the future, it is hoped that this
external communication module can be used in robotic soccer.

my exchange program in Japan.

in disaster area could be serious matters that involve many heterogeneous
agents in unpredicted environments. Robot can be used in this situation to help
rescue workers to find the victims while keeping away the rescue workers from
another danger such as re-collapsed of building that might be happened because
of the aftershocks or the structure is become weakened. These dangers of losing
lives of these rescue workers could be reduced by using robots to go inside the
disaster area.The micro robot will use two DC motors to make it move and to
control its movement. The DC motors that are used are from the type of
vibration motor. These flat micro vibration motors is supported at elastic
simple supported beam. This configuration can allow the mechanism to move and
hop cyclically.  Because of the elastic
simple supported beam is attached on the frame body, the force that is
generated is alternated between forward and backward.

micro robot will use cadmium sulphide (CdS) sensor. This sensor is used to
detect if there is any light come or not. CdS photo resistor is a common
light-sensitive component. CdS photo resistor’s resistance is depends on the
amount of lights that hits it. When it has many lights that hits it, it will
cause the micro robot’s motor to stop vibrating. On the other hand, when no
light hit it, it has high resistance, so the micro robot’s motor will start
