Abtac- This work presents an integrated monitoring
system t avoid accidents or collisions between vehicles from
both (front and back) sides. It can be used to save human
lives from a number of road accidents. To demonstrate such
a low cost system, a distance sensor frmework,
microcontroller, remotely controlled unit using radio
frequency, and an alarm unit are utilizd. A navigation
approach of the robot is also described based on the range
sensors. To verify the presented strategy, the experimental
test has been carried out in a real environment by moving
robot between diferent vehicles and objects.

NTRODUCTION
To maintain a specifc safe distace fom aoher object
is primaily about instructing a mobile robot to achieve the
desired goal. I order to atan such objectives, one of the
possible choices is to use the sensors. Robot progmng
is utilized to attan information about their environment by
using the extera sensors to allow for a more fexible
execution. Recently numerous eforts have been put in the
inteation of multiple sensors into robot systems because
advaced robots need more information about surrounding
environment. This work also demonstraes on the multiple
sensor system ad mobile navigaion. The mobile robot
ca get rage informaion aound itself fom the distace
sensors. This infomaion is used for inspction of the
environment aound the robot like deection of a entity,
notice of the dager of collision, ad identifcaion of
object position. Worldwide, lot of peole ae killed ad
injured in road crashes every yea. And even with al the
developments in te motor vehicle saety technology, the
numbe of people killed in the automobile accidents keeps
on rising. Accident causes include: driver ftigue
(fequently yawning, misjudging trafc situation, drunk
driving, using of drugs), looking at somewhere else,
playing with music, reading douments, using cell phones,
driving in fog, ad trafc high ligts. Some precations
have been made for tafc acident safety issue which
contains: Sea blt, child safety sea, ar ba, sped
limitaion, ad by physical chage in vehicle desig. We
have assumed tha b mounting sensors, light alam,
sound alam, ad vibration module in vehicle will
represent a aam sig to alert te driver. Vibraion
module will help to focus the driver in a noisy
environment. This security system will help a geat deal in

increasing road saety ad reduces collisions. I our
syste the vehicle ca b contolled by huma as well as
atomaically. The main issue for collision safety is to
control te speed of vehicle. Te na tendec for self
protection is ta drivers usualy reduce te speed of
vehicle in uncertain conditions for decision maing. In this
study, the sped of vehicle is aoaically controlled b
using distace measurement wit the help of sensors.
Maua mode contains sae hadwae ad sofwae for
the vehicle which has been already placed in it. But for the
prevention mode a extra hadwae ad sofwae will be
installed. Te hadwae for prevention mode is inerrelaed
wit the hadwae of maual mode which includes:
sensors, alams, ad control unit. When te prevention
mode is activaed, instructions ae sent towads the
predefned apaus in te vehicle.
Actually, we have implemented our proposed system on
a robotic model. Our unique work o a mobile robot is
based on the sensor method which acquires informaion to
updae the robot position. Whe a mobile robt is in
unknown environment, it will get position information
fom the sesors. According to distace information, the
mobile robot maintains its goal without crashing. This
robot is driven by two DC motors ad robot does not
require ay huma contacts othe tha using a remote
control device for commads to the microcontroller. As
soon as, the detection of a vhicle is confrmed ligt ad
sound aams get ativaed gving a sigal of deection.
These alams ae very cooperaive in case of one failure
the oter will indicae te pesence. Here, methodical
aproach is established for the development of sensor
based robot which ca be used for security purpose to
prevent fom the auomobile accidens also it ca be used
in industria applications for ragng purposes.
We ae inspired fom previous work on ultrasonic
sensor based blind spot accident prevention system [I]. I
[2] a deceleration control method of the automobile for
collision avoidace based on driver's perceptual risk is
discussed. The environmental informaion is gven by the
GPS ad sensors. Numerous works on a remote controlled
mini robt have bee already being proposed [3]. Laser
rage sensors ca aso be used for object deection,
measurements, ad to get informaion about surrounding.
A lot of study is proposed to control mobile robot based
on information of the scaning laser rage sensor [4].
Infaed sensor ring is used for line based incremental map
building [5]. Navigtion techniques ae used to move a
robot fom one position to aother as describd in [6]-[8].
