Abstract:
Nowadays, people use automatic system to
reduce their energy and time. Modern industries
are increasingly demanding process automation in
all sectors. Therefore, people use automatic
system for their environment.The variable speed
drives, which can control the speed of A.C/D.C
motors, are indispensable controlling elements in
automation systems. In this system, the tracking
vehicle is programmed to maintain a fixed
distance from the moving object and follow it. The
proposed system implements to follow a moving
object based on automatic tracking system with
three processes: distance stabling process, line
tracking system and main control system. The
distance stabling process is the main process to
control the motor’s PWM ( Pulse-Width-
Modulation) speed as the feedback of ultrasonic
sensor. According to the result of reflective
sensor, the system will control the direction of left
and right motors in line tracking system. The main
control system drives the vehicle based on the
conditions of distance stabling process and line
tracking process.This system presents the better
quality, increased production and reduced
costs.The Arduino, one of the best ways for
precision control with low cost, easy to use and
compatable with open source operating system is
used as a micro controller in this system.
