In this tutorial, I will teach you how to make a linear robot using Arduino, a very common microcontroller board. The robot uses two near infrared sensors to detect the line and based on the input received from the sensors, the Arduino will direct the motors to move with the help of motor training.

So near infrared sensors are placed on both front sides of the robot. There are four potential sensitivity factors:-

Case 1:- In this case, both sensors cannot detect the line. Both engines roll forward. As a result, the vehicle moves forward.
Case 2:- In this case, only the left sensor can see the line which means the vehicle should turn left. The left engine rotates in reverse and the right engine rotates forward. As a result, the vehicle turns left.
Case 3:- In this case, only the right sensor gets the line which means the car should turn in the right direction. The left engine rotates forward and the right engine rotates backward. As a result, the car turned right.
Case 4:- In this case, both the sensors receive the line. This means the end has come. Both engines stop rotating. Finally, the car stopped.

Now assemble your robot body. Each person can have a different body. So assemble your chassis accordingly. Most chassis come with an instruction manual, so I looked into building your chassis accordingly. Then, attach the parts to the chassis. The Arduino, along with the motor protection connected to it and the battery holder must be mounted on the chassis.
Again, attach the pockets near the front on both sides, facing down. Make sure it’s attached to the corners… Reattach the switch… Wire design to the motors and turn it into place…
Connect the motors to the motor trainer and connect the motor trainer to the Arduino board. Connect the battery to the battery using the switch. That’s all news, let’s move on to that work…Goodbye and welcome back. In this tutorial, we will learn how to make a linear robot using Arduino. In addition, this project mainly uses a 4-way barrier in the monitoring music section. In the previous article, we introduced how to create a linear robot. To do that, click this link. Also, this tutorial will be shown step by step so that you can build your own linear robot by the end of this tutorial.
This module contains four IR sensors. These can be connected to the main unit using separate jumper wires. Also, we can independently control the sensitivity of these four sensors. To do that, you can use four potentiometers in this section. We can use this music section for searching black and white and curtains. Black and white graphics were used in this tutorial. Also, this piece of music can be bought in the market at a very low price. This is as follows.

This robot needs a black track on a white screen to work. And according to the robot in this project, this dark path should be like two middle cells. The two sensors on both sides should be in the clean area. In this case, the robot is powered and the robot moves forward. Therefore, the two sensors in the center move to the white area and return to the black path, and the two sensors on the two sides move to the black path and return to the white area. Again, this process is programmed into the system. In this way, the robot moves forward on a dark path.
Next, attach the driver board to the top of the chassis. After that, connect these motors to the motor driver board. To do this, use the circuit diagram below.
After that, connect the IR module and the motor driver board to the Arduino board. To do this, use the circuit diagram above.
Then, attach a piece of foam board to the top of the Arduino board and attach the li-ion battery holder to it. At the back, install the batteries.

Now, connect this robot to the computer. Well, let’s create a program for this bot. This is how it stands.
In the loop function, the sensor values are read and cast into four Boolean variables. After that, these values are evaluated using the IF condition. If all four sensor values are 1 or 0, the robot stops. Also, if the cell values are 1 and the side values are 0, the robot moves forward. If the values one and two are 1, the robot will turn left. Also, if the fourth cell with five values is 1, the robot will move to the right.
If (SOne == 0 && STwo == 1 && SThree == 1 && SFour == 0 ) {
} else if (ONE == 1 && STouble == 1 && Third == 1 && SFour == 1) {

} else if (ONE == 1 && STouble == 1 && Third == 0 && SFour == 0) {
} else if (ONE == 0 && STouve == 0 && STouve == 1 && SFour == 1) {
Yes, enjoy this program. For that, use a black path in the white area. The complete video guide is provided below. So, we will meet in the next lesson.

How to make a linear robot using Arduino and L298N | 4 – lane tracking sensor module The lane follower is, as the name suggests, a self-driving vehicle. Basically, there are two types of linemen. In one type, the line chaser follows a black line in a white space, but, in another type, a white line follows a black space. These types of line trackers are used in factories, food delivery restaurants, medical facilities to deliver medicine to sick patients, etc. Now, we will build a line following robot using IR sensors, L293D, and microcontroller. Here, we will understand the function of the IR sensor and the L293D and see how it can be used in our linear project.
So how does an IR sensor work? The IR sensor consists of an IR LED and a photodiode. The IR LED emits IR rays continuously and the photodiode acts as a receiver for the IR rays emitted by the IR LED. Every time the IR LED rays hit an object (Note: the screen should not be black), the rays bounce back. When the photodiode detects the IR radiation emitted by the IR LED, then the output of the IR sensor is converted to digital. If the photodiode does not receive the IR radiation emitted by the IR LED, the output is low. When it comes to the working voltage of the IR sensor, it works at 5V and the output of the IR sensor module can be 5V (high) or 0V (low).
The L293D module is an h-bridge motor driver circuit. By using the L293D module, we can control two motors at the same time. it can also drive the car in any direction, making it perfect for a robotics project. The working voltage of the unit is from 4.5V to 12V. The output current of the module is 1A per channel. The pinout of the module is shown in the picture below.
The link for the linear program is shown below. First, let’s see the connection between the Arduino and the IR sensor. The IR sensor has 3 pins, where the VCC and GND pins are connected to the 5V supply and the GND pin of the Arduino. The output pin of the IR sensor, which is connected to the left side of the line follower (left sensor), is connected to pin 4 of the Arduino. The output pin of the IR sensor, which is connected to the right side of the receiver line (right sensor) is connected to pin 3 of the Arduino. The image below shows the location of the sensor on the tracking robot.

Now, let’s see the connection between the Arduino and the L293D motor. The L293D module is a 3 pin, connected power supply. The right pin is connected to the 5V of the Arduino, and the left pin is supplied with 9V from the battery. The middle pin is affected (insert the negative of the battery and the GND pin of the Arduino and connect it to the GND pin of the L293D module).
Terminal blocks M1 and M2 are used for connection
