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. Very simple and nice project. The voltage at the inverting input pin 2 of operational amplifier A1 is higher than the reference voltage at its non-inverting input pin 3 and therefore the amplifier folpowing at pin 1 becomes zero.

Embedded-Electronics: line follower robot using

The abov given program of line follower robot is perfectly rut or not??? Basically two types of line follower robots are: In our previous projects, we have made a black line follower robot using arduino but this time we are going to make white line follower using microcontroller. Basics, Usage, Parameters and Applications. The outputs of comparators are connected to pin number P0.


If there is a deviation to left, left motor is stopped and right motor is activated. The logic executed by the microcontroller for keeping the robot in track is illustrated in the table below. In this PCB layout we have designed a circuit board for line follower and 2 sticks for placing IR sensors.

Automated Line Follower Robot

So we added a motor driver circuit to get enough voltage and current for motor. This explained behaviour of light is used in this line follower robot. The inverting input pin 2 of operational amplifier A1 goes below the automzted voltage at its non-inverting input pin 3 of operational amplifier Automzted and therefore output pin 1 goes high.

Line follower robots were one of the earliest automatic guided robots. Log into your account. A line follower robot with pick-and-placement capabilities is commonly used in manufacturing plants. Then comparator compares both voltages and generates a digital signal at output.

Similarly, comparator A2 compares the input voltage from phototransistor T1 with a fixed reference voltage. And then in main function we checks inputs and sends output according to inputs to output pin for driving motor.

The sensor senses the reflected light aautomated give an output, which is fed to the comparator. Remaining sections of the circuit were explained already. When the robot is back on line again, both motors are started. In the circuit, the sensors phototransistors are used to detect the white strip on a black background. We shall try to publish C code later. The sensor senses the light reflected from the surface and feeds the output to the comparator.

Here in this line follower robot when sensor senses white surface then microcontroller gets 0 as input and when senses black line microcontroller gets 1 as input. Heart rate monitor with sms alert. These move on a specified path to pick the components from specified locations and place them on desired locations.

Project Engineer 22 December Awesome Timer IC Projects. AT89S52 from Atmel is the microcontroller used here. Power Bank for Smartphones.

Concept of line follower is related to light. The path to be taken is indicated by a white line on a black surface.

Schematic of the motor driver circuit is shown in the figure below. ULNA is a high current mAhigh voltage 50V darlington array consisting of seven darlington pairs with common emitter and open collector. The current supplied by the microcontroller to drive the motor is small.

The figure shown below depicts the sensor circuit. 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. Microcontroller sends commands to this motor driver and then it drive motors. Line follower actually senses the line and run over it. I need help in line following robot using microcontroller. Concept of Line Follower Robot Concept of line follower is related to light.
