Hello Friends, Today in this article we will Learn to make a “Line following robot without microcontroller” The Line Follower Robot is also called Path following Robot; We can control our Robot according to our instruction. The line follower Robot is used to make such a purpose that is used to follow a certain path. It usually follows a black line on a white surface or a white line on a black surface. It works sharply when it is made properly. Line Follower Robot plays a vital Role in industries to make industrial work easily. This type of Robot used on the assembly line. In the industries, This type of Robot is used to carry the goods from one place to another place.
Types of Line following robot
- Simple Line following robot without microcontroller Using Lm358 IC (voltage comparator Ic)
- Logical 8051 Microcontroller Based Line following Robot
- Arduino Uno Based Line following robot
- Line follower Robot Using Pic (Programmable Interface Controller)
Here We will Learn to make Line following robot without microcontroller.
Let’s Start The Project.
Components Required for Line following robot without microcontroller
- PCB (Printed circuit board) 1 pcs
- IR Sensor 2pcs
- L293D Motor Driver IC 1pcs
- Lm358 (Voltage comparator IC ) 2 pcs
- 100 Rpm BO Motor 2 pcs
- BO Wheels 2 pcs
- Free Caster Wheel 1 pcs
- Chassis 1 pcs
- 7805 Voltage Regulator IC
- 9 volt battery 1 pcs
- 9 volt Battery snapper
- Soldering Iron
- Solder Wire
Before Making to start This project Lets Know about Its important IC which will be used here
this is infrared based sensor used to detect the obstacle or any surface area here it plays very vital role to make it successful.
L293d Motor Driver IC
This is motor driver ic which is used to drive the motors safely through it .
7805 Voltage Regulator IC
This is voltage converter ic which is used to convert 9-12 volt into 5 volt .
LM358 Voltage Comparator IC
This ic is used to compare two different voltage in a different parameters, Here working of robot is controlled through this ic.
Let’s Start to make Line following robot without microcontroller project with some Easy steps
First of all we have to collect all these components that is:
PCB (Printed circuit board) 1 pcs, IR Sensor 2pcs , L293D Motor Driver IC 1pcs , Lm358 (Voltage comparator IC ) 2 pcs , 100 Rpm BO Motor 2 pcs, BO Wheels 2 pcs , Free Caster Wheel 1 pcs, Chassis 1 pcs, 7805 Voltage Regulator IC , 9 volt battery , 1 pcs 9 volt Battery snapper, pieces of Wire , Soldering Iron, Solder Wire.
We need all these components as well for making this project.
Make a circuit diagram and insert all the components in this PCB in a appropriate manner.
Circuit will look like this . Now your circuit is ready to use.
Insert all the components. and you can connect it to 9-12 volt battery.
Here we are using 9 v battery as well as 12 volt battery.
Now your circuit is ready.
Now lets come to Robotics body.
As here we are seeing there is on motor and one bo wheel. So first we hav to connect this.
As you are seeing I have connected two wheels in a same manner.
Now we have to connect its body and chasis as I have connect here and tighted the screw in correct place.
Now also we have to connect the wheels and motors, as in the picture.
After connecting all parts. Now it’s a time to connect with the circuit .
After connecting to the circuit now its ready to use.
Now we have successfully developed this project, and we can see by our experience that how smoothly this line follower robot does work.
This robot is ready to work on a black as I have drawn a here a black path for this robot. So as you will start the robot, it will only follow the black path.
Now your Project is Ready, Keep enjoying this project.
