The microcontroller is programmed to make the robot move forward, turn right or turn left based on the input coming from the comparator. And when both sensors comes on white line, robot stop.

All Time Fav Videos! The program is written assembly language. The outputs of comparators are connected to pin number P0. The current supplied by the microcontroller to drive the motor is small. Circuit diagram of the comparator section ilne shown in the figure below. It autmated sufficient current to drive the motor. Motor driver is used for driving motors because microcontroller does not supply enough voltage and current to motor.

AT89S52 from Atmel is the microcontroller used here. The hexcode was burnt into the microcontroller using an in system programmer ISP. Can u rboot me the pcb file of line following robot using microcontroller. Also at89c551 project serves as a platform for advanced line follower robots which works on complex algorithms. Line follower robots were one of the earliest automatic guided robots. Concept of line follower is related to light.


When no light falls on the phototransistor, it is cut-off. Log into your account.

Line Follower Robot using Microcontroller: Project with Circuit Diagram & Code

If this voltage is greater than the reference voltage the comparator outputs a low voltage, and if it is smaller the comparator generates a high voltage that acts as input for the decision-making device microcontroller. IR transmits infrared lights. A set of comparators and fololwing motor driver circuit will happily do the job. Can you tell me list of component required for this project?

Microcontroller sends commands to this motor driver and then it drive motors. Leave a Reply Cancel reply Your email address will not be published.

So we added a motor driver circuit to get enough voltage and current for motor. Can I use gear dc motor with another rpm: The job of the comparator circuit is to convert analog voltage output of the sensor into a digital format for the microcontroller to read.

Shall you introduce the programming software for automaetd circuit diagram. LM is used as comparator. The sensor senses the light reflected from the surface and feeds the output to the comparator. But try to furnish as much informations as posible like the program language, the compiler used etc so that even a novice shall be able to use it.

Very simple and nice project. Can you give details to burn this assembly lie program which is given above for line follower using microcontroller robot in IC AT89s52 …. The robot is built using microcontroller AT89C51 used as the decision-making devicemotor driver LD, operational amplifier LM comparatorphototransistor sensor and a few discrete components.

Automated Line Follower Robot

The microcontroller, based on the inputs from sensor T1 say, left and sensor T2 qt89c51, rightcontrols the motor to make the robot turn left, turn right or move forward. If there is a deviation to right, the program stops left motor and runs right motor and sutomated until the robot comes back from the deviation. Quote and Order boards in minutes on https: The sensor output is fed to the microcontroller, which takes the decision and gives appropriate command to motor driver LD so as to move the motor accordingly.


In program first of all we defines input and output pin.

Please provide the complete component list. When a particular input line say pin 1 is made high the corresponding output line pin 16 goes low and vice versa. In the circuit, the sensors phototransistors are used to detect the white strip on a black background.

The output of the sensor circuit is taken from the points labelled A and B robor the circuit diagram. Switch S2 is used for manual reset. Collectors of phototransistors T1 and T2 are connected to the inverting inputs of operational amplifiers A2 and A1. Basically, a line follower robot is a self-operating robot that detects and follows a line drawn on the floor.

When the robot is back on line again, both motors are started. When sensor T2 is above the black surface, it remains cut-off as the black surface absorbs virtually all the light falling from LED2 and no light is reflected back.

The outputs of the microcontroller are fed to the motor driver. The comparator compares the analogue inputs from sensors with a fixed reference voltage.
