Line follower

For turning, one of the motor is switched off. On the floor, place some black electrical tape along the path you wish the robot to follow. After the starting screen, the robot will calibrate itself.

We will be using differential drive for maneuvering our bOt i. Try it out Draw your own racing track Let your robot run the race!

It will scan the floor to detect Line follower line.

Line Follower Robot

The comparator circuit may be designed in two ways. Tape the paper to the ground so the robot will not cause the paper to slip.

This voltage is compared with the fixed reference voltage in comparator circuit and hence it is converted into logic 0 or logic 1 which can be Line follower by the controller.

The corresponding analog voltage is induced based on the intensity of reflected light. Code This sketch demonstrates the line following capabilities of the Arduino Robot.

Compete with other robots to see which one makes it faster! In simple words the black surface absorbs the light and the white surface reflects it, this is the basic concept behind making a line follower.

If the surface is white, more intensity of light gets reflected and for black surface very less intensity of light is reflected. Motors and Driving Mechanism: The sensors are placed in such a way that the white line lies in between both the sensors when the bOt is placed on the white track painted on black surface to move.

The right angle clamps ensure more rigidness. The reflection and absorption coefficient of light depend upon material, color of platform and other factors. Put the robot on top of the line and turn it on. Sensor circuit contains emitter, detector and comparator assembly.

If we switch off the left motor, the bot will turn left and vice versa. When the bot is moving straight both the motors should have equal speed.

Line Follower

You can choose a motor of rpm around and a torque of 1kg-cm 3. This shape will be your racing track. We recommend you to make a small size and light weight bOt. The line should be around 3cm 1 inch wide. For example in the above figure if the bot is located in position 1, then bOt will move forward and if the bOt is in position 2 it will have to turn left.Line follower Robot is a machine which follows a line, either a black line or white line.

Basically there are two types of line follower robots: one is black line follower which follows black line and second is white line follower which follows white line. A line follower is an autonomous bot that can follow a specific colored line painted on a surface of different contrast, such as white on black.

Jul 26,  · I made a line follower robot with PIC16F84A microprocessor equipped with 4 IR sensors. This robot can run on the black and white lines. What is a line follower robot and how to make a simple line follower robot project? Line follower is an autonomous robot based around microcontroller which follows either black line in white are or white line in black area.

Learn to design a line follower robot with circuit diagram and code. Examples > Robot Line Following. Take a large piece of paper (or tape smaller pieces together to make a big one) and draw a shape on it using a thick black marker.
