What is the purpose of line follower robot?
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 does a line follower work?
A line follower consists of an infrared light sensor and an infrared LED. It works by illuminating a surface with infrared light; the sensor then picks up the reflected infrared radiation and, based on its intensity, determines the reflectivity of the surface in question.
How do I connect Arduino to IR sensor?
The connections for the IR sensor with the Arduino are as follows: Connect the negative wire on the IR sensor to GND on the Arduino. Connect the middle of the IR sensor which is the VCC to 5V on the Arduino. Connect the signal pin on the IR sensor to pin 8 on the Arduino.
How do you write ROBOTC code?
Program Code Text written as part of a program is called “code”. You type code just like normal text, but you must keep in mind that capitalization is important to the computer. Replacing a lowercase letter with a capital letter or a capital letter with lowercase, will cause the robot to become confused.
What is Arduino line follower Robot?
Here in this arduino line follower robot when sensor senses white surface then arduino gets 1 as input and when senses black line arduino gets 0 as input. The whole arduino line follower robot can be divided into 3 sections: sensor section, control section and driver section.
How to connect an IR sensor to a line follower Robot?
The output pin of the IR sensor, which is connected to the right side of the line follower (right sensor) is connected to the pin 3 of the Arduino. The below fig shows the sensor’s position on the line follower robot.
How does line follower works?
Concept of working of line follower is related to light. We use here the behavior of light at black and white surface. When light fall on a white surface it is almost full reflected and in case of black surface light is completely absorbed. This behavior of light is used in building a line follower robot.
What is the behavior of light used in building a line follower?
When light fall on a white surface it is almost full reflected and in case of black surface light is completely absorbed. This behavior of light is used in building a line follower robot. In this arduino based line follower robot we have used IR Transmitters and IR receivers also called photo diodes. They are used for sending and receiving light.
