How can we make a Line Follower Robot in 8051 microcontroller?

How can we make a Line Follower Robot in 8051 microcontroller?

Working of Line Follower Robot using 8051 Here in this project we are using two IR sensors pair. Suppose we are calling left sensor and right sensor of IR sensor Pair, then both left and right sensors sense nothing or black line then robot move forward. And when left sensor senses white line then robot turn left side.

What is the use of Line Follower Robot?

The sensor based black line follower robots are one of the most basic robots used to follow black line on white background or vice versa. These robots may be used to in various industrial and domestic applications such as to carry goods, floor cleaning, delivery services and transportation.

Which sensor is used in line following robot?

4} IR SENSOR For line sensing operation, IR sensors are the one which are widely used for the development of a line follower robot. There are some basic things to follow where white surface of the black line reflects light and the black line receives it after the transmission.

How do you make a line follower robot?

Which sensor is best for line follower robot?

QRD1114 IR reflective line/object sensor and CNY70 reflective optical sensor are the most commonly used sensors for line follower robots. The CNY70 is a reflective sensor that includes an infrared emitter and phototransistor in a leaded package which blocks visible light.

How do you program a line follower robot?

Connect VCC to 5V and GND to Ground and then connect the Output pin to the Analog/Digital pin of Arduino.. any way u like it. If you are following this particular code then connect the output of LEFT SENSOR to digital pin 2 of your Arduino and the output of RIGHT SENSOR to digital pin 3 of the Arduino.

How do you get a robot to follow a line?

Testing the Line Follower To test the robot, first create a track. You can use black electrical tape to create a line on any white surface. Create a circle with the tape and place the robot in a way that both the IR sensors are on either side of the tape. Toggle on the switch and watch the robot follow the line.

How do you make a line follower robot at home?

Step 2: Hardware Installation

  1. Assemble the 2WD Smart Car Chasis 2 Wheels.
  2. Connect the IR sensor to Analog to Digital and Comparator Module.
  3. Then, connect the output pin to Arduino UNO analog pin.
  4. Connect Vin to 5V and GND to GND in Arduino UNO.
  5. Then, connect the motor driver pin to Arduino UNO pin.

How do you write code for line follower robot?


  1. Step 1: Connect the circuit as shown in the schematic.
  2. Step 2: Use the Arduino IDE to write your own code.
  3. Step 3: Upload your code to the Arduino and connect it to the batteries or you can even use a power bank to run the Arduino.
  4. Step 4: Test it on a black path.

How does line following robot follow line?

Abstract: The line follower robot is a mobile machine that can detect and follow the line drawn on the floor. Generally, the path is predefined and can be either visible like a black line on a white surface with a high contrasted color or it can be invisible like a magnetic filed.

How many sensors does a line following robot have?

two IR sensors
To follow our line, we will need two IR sensors, placed on each side of the line. When both IR sensors are not on the line, our robot will simply go straight. When one sensor is on the line while the other is not, we will have to tell the robot to turn in the direction of the first sensor.

What is the autonomous line following vehicle function?

Abstract. The line follower is an autonomous robot that detects and follows a line. The path may be visible like a black line on a white surface or may be reverse of that or it can be invisible like a magnetic field. A close loop control system is used in the robot.
