How to make non-programmable Line Follower Robot

#Robot 3

Whenever we heard this term robot during our schooling, college life & specially college technical events & fest where such type of robotic event going, always we have curiosity about that perhaps we can make our own robot & play & explore with it.

Most of the time when we heard robots then one name is very common which even very famous in robotic events & that name is “Line Follower Robot” means LFR.  It is that kind of robot which is capable to follow the line according to pre-defined track. So whenever we start to build such robot then one thing become very tough for most guyzz is called Programming of robot, But here in this tutorial we are going to learn to build the line follower robot without programming.

So to start for building the line follower robot we need have list of components as shown in below image.

Step 1 :- The first step toward build the free wheels robot is assembling of robot, so for assembling of robot you should go through our how to assemble the robot section. In that section we can assemble the robot in proper manner, kindly follow the instruction during assembling of robot.

After the complete assembling of robot it should be look like this as shown below image.

step1

 

We supposed that you have successfully assemble the robot by following the proper steps as mentioned in tutorial.

Step 2 :- As you can find out both the motor have 2 ,2 wires each respectively, so now connect the 2 wires of each motors connect to our green color motor driving board which mounted just middle of chassis. As you can find out in below images that we connect one motor to output 1 of board & other motor to output 2 of board, according left & right position of motor, means left motor to output 1 & right motor to output 2.

step2

 

Step 3 :- Now take 3 single pin wires (Try to go with different color), if you look at both the IR Sensors the you will find that in each IR sensor has 3 pinout which name like.. VCC, GND, VOUT. So connect one side of 3 single pin wires to each each pinout of first IR sensor, as shown below.

step4

Now after that rest of side of 3 single pin wires are need to connect on our green color motor driver board which just place middle of chassis. Other side wires connection should be like this VCC pin of first ir sensor connected to +5V of board , GND pin to GND of board & VOUT pin of ir sensor is should be connected to input 2 first pin of board as shown below.

step5

As you can see into above image that in our LFR robot we have 2 Sensor right & left sensor, so in above image we have done right sensor connection with respected to right side motor.

step6

Now repeat the same process with left means 2nd ir sensor, take another 3 pin wires & connect to GND, VCC, & VOUT of sensor & other side to motor driver board in same manner, Kindly refer below.

step7

step8

Step 4 :- As for now one one pins of  input 1 & 2 respectively connected to VOUT of both IR sensors respectively  & other one one pins remain unconnected.

step9

step10

Now for rest of connection we will take another single pin wire & connect to rest of inputs pin of motor driver board with each other

step11

If we repeat the connection one again in short form so should be like this, both input 1 & 2 first pins connected to +VOUT of ir sensors & other remaining pins means GND to GND & VCC to +5V of board respectively connected.

Now for Line Follower Robot, IR sensor position of LEDs should be downside because the line which followed by robot is on ground or down side of robot, So we bend it down side.

step13

Step 5 :- Now Supply connect the power supply by using 9V adapter & 9V battery, Here we are using 9V adapter for giving the power supply to robot.

step14

 

Step 6 :- Now press the main power switch button in middle of robot which white in color & you will find power LED will on & robot Start moving any direction. Due to movement of robot in any direction that why it is called free wheels robot.

As you can shown in images below.

step15

 

To make it wire free from adapter you can apply the 9V battery you can use the battery Snipper for battery as shown below image.

step16
