You may try the Arduino based circuit as well to see how the same project is developed using different controllers. The path to be taken is indicated by a white line on a black surface.

Automated Line Follower Robot

LM has inbuilt two low noise Op-amp. A set of comparators and a motor driver circuit will happily do the job.

These capacitors are very essential and without them you can expect sudden crashes from the microcontroller side. Monday, Rbot 31, Such ISP programmers are readily available in electronic shops and online electronic stores.

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. Switch S2 is used for manual reset.

LM is a general purpose quad opamp which can be operated from a single supply. Log into your account. When a particular input line say pin 1 is made high the followingg output line pin 16 goes low and vice versa. Please enter your comment! 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 at89f51. 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.

This explained behaviour of light is automatee in this line follower robot. And then in main function we checks inputs and sends output according to inputs to output pin for driving motor.

If there is a deviation to left, left motor is stopped and right motor is activated. Similarly, comparator A2 compares the input voltage from phototransistor T1 with a fixed reference voltage.

Also this project serves as a platform for advanced line follower robots which works on complex algorithms. Can you tell me usinb of component required for this project? In this PCB layout we have designed a circuit board for line follower and 2 sticks for placing IR sensors.

Schematic of the motor driver circuit is shown in the figure below. Circuit is very simple for this line follower robot. The hexcode was burnt into the microcontroller using an in system programmer ISP. When light falls on the phototransistor say, T1it goes into saturation and starts conducting. One for the left side and the other for the right side.

A line follower robot with pick-and-placement capabilities is commonly used in manufacturing plants. Output of the left comparator is connected to P1.

Embedded-Electronics: line follower robot using

Usually, the line follower robot works on a closed loop feedback algorithm where the feedback from the line sensor is used by the controller for correcting the path of the robot. They are able to follow a line marked on a contrasting background, usually a black line on a white surface or a white line on a black surface. We have autmated two sensor namely left sensor and right sensor.

Heart rate monitor with sms alert. Circuit diagram of the comparator section is shown in the figure below. The table below shows the voltage af89c51 nodes A and B for the possible orientations of the sensor module. Line follower robots were one of the earliest automatic guided robots.
