If there is no deviation to right, the program checks for a deviation to left. The output of the sensor circuit is taken from the points labelled A and B in the circuit diagram. Linr has inbuilt two low noise Op-amp.

Automated Line Follower Robot

The microcontroller, based on the inputs from sensor T1 say, left and sensor T2 say, rightautomaged the motor to make the robot turn left, turn right or move forward.

The line follower robot presented here is designed ar89c51 follow a black line on a white background. A set of comparators and a motor driver circuit will happily do the job. Reference design for Laser Drive Follwoing 6 December One for the left channel and one for the right channel. In program first of all we defines input and output pin.

Therefore a motor-driver IC is used. LM is used as comparator. The sensor senses the reflected light to give an output, which is fed to the comparator. Concept of line follower is related to light.


The hexcode was burnt into the microcontroller using an in system programmer ISP. Door Sensor 19 December They are able to follow a line marked on a contrasting background, usually a black line on a lime surface or a white line on a black surface. Basics, Usage, Parameters and Applications. Circuit is very simple for this line follower robot. The first part of the program initializes Port 1 as input port and Port 0 as output part.

And when both sensors comes on white line, robot stop. Shall you introduce the programming software aufomated this circuit diagram.

Circuit diagram of the comparator section is shown in the figure below.

The inverting input pin 2 of operational amplifier A1 goes below the reference voltage at its non-inverting input pin 3 of operational amplifier A1 and therefore output pin 1 goes high.

Can you tell me list of component required for this project?

One for the left side and the other for the right side. The LDR has an inverse relationship between its resistance and the light falling on it. Then the programs checks whether there is a deviation to right. The automatrd is built using microcontroller AT89C51 used as the decision-making robltmotor ueing LD, operational amplifier LM comparatorphototransistor sensor and a few discrete components. Basically, a line follower robot is a self-operating robot that detects and follows a line drawn on the floor.

And then in main function we checks inputs and sends output according to inputs to output pin for driving motor. These move on a specified path to pick the components from specified locations and place them on desired locations. Useful Raspberry Pi Projects. This reference voltage can be adjusted by changing the value of the kilo-ohm preset.

I need help in line following robot using microcontroller. Such ISP programmers are readily available in electronic shops and online electronic stores. It provides sufficient current to drive the motor. Out of the seven channels available in the IC,only two are used here.


The table below shows the voltage at nodes A and B for the ussing orientations of the sensor module. Career advice and jobs related to electronics and IOT.

The outputs of comparators are connected to pin number P0. When no light falls on the phototransistor, it is cut-off. Interfacing Nokia Display to Micro Controller Moisture sensing automatic plant watering system using The program is written assembly language.

Line Follower Robot using AT89C51 | Full Project with Source Code

Lastly if there is no deviation to left or right, both motors are kept ON. Heart rate monitor with sms alert. These capacitors are very essential and without them you can expect sudden crashes from the microcontroller side. Sensors for Robotics and Artificial Intelligence. Usjng you does not need a microcontroller for implementing such a simple robot.

Very simple and nice project. AT89S52 from Atmel is the microcontroller used here. If there is a deviation to right, the program stops left motor and runs right motor and waits until the robot comes back from the deviation.

We have used two sensor namely left sensor and right sensor. In the circuit, the sensors phototransistors are used to detect the white strip on a black background. Project Engineer 22 December In this PCB layout we have designed a followig board for line follower and 2 sticks for placing IR sensors.

When the robot is back on track again, both motors are started.
