This Robot works based on a feedback signal sent by the Infra red sensors which is fixed on the sides of the chasis to the controller which processes the nature of track.

This Infrared sensor output at a logic-low L state, when it detects a black color and vice versa. So in normal condition white floor sensor output is high. When these two sensors senses a white surface that is when there is no reflection the robot goes straight.
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.
The microcontroller is programmed to make the robot move forward, turn right or turn left based on the input coming from the comparator. The outputs of the microcontroller are fed to the motor driver. The current supplied line follower robot using 8051 the microcontroller to drive the motor is small.
Automated Line Follower Robot
Therefore a motor-driver IC is used. It provides sufficient current to drive the motor.
When light falls on the phototransistor say, T1it goes into saturation and starts conducting. When no light falls on the phototransistor, it is cut-off.
Phototransistors T1 and T2 are used for detecting the white line follower robot using 8051 on the black background.

Collectors of phototransistors T1 line follower robot using 8051 T2 are connected to the inverting inputs of operational amplifiers A2 and A1. The signal voltage at the inverting input of the operational amplifier is compared with the fixed reference voltage, which is formed by a potential divider circuit of 5.
This reference voltage can be adjusted by changing the value of the kilo-ohm preset. One for the left channel and one for the right channel.
Line follower robot using 8051 of the motor driver circuit is shown in the figure below. When a particular input line say pin 1 is made high the corresponding output line pin 16 goes low and vice versa. These capacitors are very essential and without them you can expect sudden crashes from the microcontroller side.
Switch S1, capacitor C3 and resistor R9 forms a debouncing reset circuit for the microcontroller.
R12 and R13 are pull-up resistors. Remaining sections of the circuit were explained already.
DIY Line follower robot using microcontroller with Circuit and Program
The first part of the program initializes Port 1 as input port and Port 0 as output part. Then the programs checks whether there is a deviation to right. 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.
When the robot is line follower robot using 8051 on line again, both motors are started.
