Line Following Robot Full Project

Line Following Robot
Full Project
In this post we will talk about Line
Following Robot. Actually robot is kind
of human made with machinery.
Today’s time is of automation and
only automation. So in this time the
manufacturing is not possible with
the help of human. The world is
Robotics world and Line Following
Robot is the most important project
of this Robotics world. In this post I
will completely explain that how the
Line Following Robot works and what
components it has but before this
explanation I would like to tell
something about Line Following
Robot. Line Following Robot is a robot
that is designed to follow a specified
path to pick and placement various
things. In the big manufacturing
industries like vehicle and machine
production industries only Line
Following Robots are used to
manufacturing.
Now I will talk about that how a Line
Following Robot works and what are
the basic components of this robot.
Listen, Don’t hurry up to make this
robot because first understand the
basic block diagram of a Line
Following Robot and then go into the
design of the circuit. The block
diagram of robot you are seeing
below. I will explain the working and
functionality of the whole block
diagram block by block.
Line Following Robot Block Diagram
As you can see that there are 5 basic
components of Line Following Robot.
1. Sensors : There are two sensors
used in the robot. The main
functionality of sensor is to sense the
reflection of light. Now i will tell you
that how the sensors work in this
project. With the sensors there are
two source lights also situated in the
robot. We know that white color
reflects light and black color absorbs
the light so we make a white strip on
the black background. When the
robot’s sensors are on black
background there will be no light
reflection and if the sensors on white
strip there will be a reflection of light.
The sensors sense the light behavior
and give their output to their
corresponding comparators.
2. Comparator: The comparators are
such a device which has some
reference voltage. When the
comparator gets an input voltage
from the sensors output circuit the
compare it with the reference voltage.
If the sensor voltage is greater than
reference voltage the comparator
gives small output and if the sensor’s
voltage is small than reference voltage
of comparator then the comparator
gives high voltage output. Both the
outputs of comparators are fed to the
micro controller that is also known as
decision making device.
3. Micro controller: Micro controller
is called decision making device that is
programmed with a high level
language such as C or C++ or
assembly. There are some certain
codes written in the memory of micro
controller to handle the input of
comparator and giving the output of
motor driver circuit.
4. Motor Driver Circuit: Motor driver
circuit is the final block of this robot.
When the micro controller gets input
from comparator it gives some output
to the motor driver L293D. This is
motor driver IC that can easily interact
with the ATMEGA micro controllers. It
takes the decision of driving the
motor in left or right and slow or fast
according to the micro controller
signals.
I am just giving the circuit diagram of
Line Following Robot not only the
whole circuit functionality. There are

Robot functionality.
