Which sensor is used in line following robots?

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 line following robots 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.

What are line following robots used for?

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.

How does line following work?

How many microcontrollers are there in line follower Robot?

This circuit mainly consists of 8051 microcontroller, two IR sensors, motors and motor driver IC (embedded in a module). The line follower robot needs mechanical arrangement of the chassis. I have used a 4WD Acrylic chassis.

How to use Lineline following robotic vehicle circuit?

Line Following Robotic Vehicle Circuit Working 1 Initially draw the path on a light colored surface with black color tape. 2 Place the robot on the floor. 3 Now power on the circuit. 4 Robot moves in the specified path. 5 When it moves out of path, sensors check it and automatically adjust the robot.

How are the DC motors of the robot connected to controller?

The DC motors of the robot are connected to the controller using a motor driver IC. As the output of the controller is maximum 5V with very small current, it cannot drive the motors. So, to amplify this voltage motor driver IC is used.

How does the robot follow the fixed path?

When robot is placed on the fixed path, it follows the path by detecting the line. The robot direction of motion depends on the two sensors outputs. When the two sensors are on the line of path, robot moves forward.
