How does a line following robot follow a line?

The line follower robot is a mobile machine that can detect and follow the line drawn on the floor. Definitely, this kind of robot should sense the line with its infrared ray (IR) sensors that installed under the robot. After that, the data is transmitted to the processor by specific transition buses.

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.

Which sensor is used in line following 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 is a line follower Robot based on ATmega8?

In this post, we are going to make a line follower robot using atmega8. Line follower robot is based on tracking a line of particular colour. This is done by infrared (IR) sensor. IR sensor gives us a digital output. The output of ir sensor is fed to input of atmega8, in accordance with the output of ir sensor it manipulates PortD.

What kind of microcontroller does AVR ATmega8 use?

A popular family of microcontroller is AVR series from Atmel. A member of the popular family is ATmega8. ATmega8 is chosen because it has just the required amount of resources and is very low cost. The MCU cannot drive the motors (used to actually make the robot run) directly, so a motor driver is used.

Can a line follower Robot use AVR microcontroller?

Today we will use AVR microcontroller to build a Line follower Robot. Mostly IR sensors are used to detect lines. The IR sensors are good in detecting white or black surfaces. Although you can use other sophisticated sensors which will be able to detect all colours and can make a robot which can follow all colour lines.

How to program ATMega16 microcontroller using usbasp?

Here the Atmega16 is programmed using USBASP and Atmel Studio7.0. If you don’t know that how Atmega16 can be programmed using USBASP then visit the link. Complete Program is given at the end of the project, just upload the program in Atmega16 using JTAG programmer and Atmel Studio 7.0 as explained in previous tutorial.
