The Line Follower. The line follower has 2 sensors which can detect a white surface (within the range of 1-2cm). It works by emitting IR (InfraRed) light and recording how much is reflected back. If a lot is reflected back, it can be deduced it is close to a white surface. If a little is reflected back, it can be deduced that the surface is black, or the sensor …
Let's make a fully autonomous robot using Arduino and IR sensors. It can follow a black line on white surface. Watch video for more! Components used: Piece of cardboard/ Acrylic sheet; Arduino Uno; IR sensor; BO motor ; Wheels; Caster wheel; L293d IC; PCB; Flexible wire; Battery; Fix all components on acrylic sheet and make a chassis as shown in pictures. Now make all connection As per the ...
That is proximity sensor and IR sensor. The proximity sensor used for path detection and IR sensor used for obstacle detection. These sensors mounted at front end of the robot. The microcontroller is an intelligent device the whole circuit is controlled by the microcontroller. Block Diagram of Line Following Robotic Vehicle with Microcontroller
IR sensor array – The line follower is designed to follow black strips of line. For this, a sensor which can detect the colour of underneath surface is required. The IR sensors can detect the colour of underneath surface based on reflective/non-reflective indirect incidence. The IR LEDs emit IR radiation which in normal state gets reflected back from the white surface around the black line ...
· A line follower robot is an electronic system that can detect and follow a line dr awn on the floor. The robot uses IR sensors to sense the line, an array of 3 IR LEDs and sensors, facing the ground have been used in this setup. An IR sensor can be fitt ed near the patient’s bed to which connection has been made with the robot too. The switch ...
· Hello everyone. This is my first time working with an arduino. I’am building a line follower bot using an IR array which has 8 IR sensors. I’am using a L293D motor shield with 2 motors connected to input 1 and 4 of the shield. I imported the adafruit motor shield library and ran its motor test example and it worked fine. Here’s the example code: #include <> AF_DCMotor motor(4 ...
· Line Follower Robot is able to track a line with the help of an IR sensor. This sensor has a IR Transmitter and IR receiver. The IR transmitter (IR LED) transmits the light and the Receiver (Photodiode) waits for the transmitted light to return back. An IR light will return back only if it is reflect by a surface. Whereas, all surfaces do not reflect an IR light, only white the colour surface ...

If a lot is reflected back, it can be deduced it is close to a white surface. If a little is reflected back, it can be deduced that the surface is black, or the sensor is not near a surface. A light ...
· Hi guys, just notice, that "white" and "black" only related to visual range, - mcmeters. They could be the same reflective surface in IR , >+ mcmeters.
· IR Sensor Module (x2) 9V Battery; Geared Motor (x2) Wheels (x2) Connector Wires; Working of Arduino Line Follower Robot With Obstacle Detection . According to the above circuit diagram, we notice that a microcontroller (Atmega328p) is used to communicate with the whole system for processing the robotics functions. First, we need to connect both Vcc and ground pins of the …
· Line Follower is a very simple robot ideal for beginner electronics. The robot travels along the line using the iR sensor. The sensor has two diodes, one diode sends infrared light, the other diode receives the reflected light from the surface. When the infrared rays fall on the white surface, they are reflected back. When infrared light fall a black surface, the light is absorbed by the black ...
when the IR sensor sees the black line one wheel of the bot rotates and the bot turns away from the line. when the IR sensors sees the white background the other wheel rotates and the bot turns slightly towards the line. The above two steps occurs one after other in a repeat mode very fastly in a very short time which gives us the movement of the bot in the path following the black line. It ...

· Place the line following sensor on the standoffs as shown in the figure. Using M3 nuts, fix the sensor to the lower base plate. Turn the lower base plate back to initial position. Now, using 8mm M3 bolts, mount 40mm standoffs on the holes provided on the base plate. Mount evive on upper base plate using two 12mm M3 bolts.
