Project Description :

Line follower robot is a mobile machine that can detect and follow line which is drawn on the floor.The path can be a visible black line on a white surface (reverse). Robot should read for identifying his position in some time, after that, the control system will create for robot some orders to respect components in purposes of making correct movements of the robot.

This small line follower robot , was designed to be easily built at home without any special equipment, and using a minimum number of mechanical parts. You wont need more than 2 small motors, 2 free wheels and a piece of PCB  and sure. your soldering iron!

The main trick making this design simple and affordable, is that the robot's chassis is actually the main board of the robot, where some supports for the wheels - also made of small parts of copper boards - are soldered to it.

 

 

So this unique technique was used, which is to use pipe clamps, originally used to mount water pipes all along the walls of buildings . Those pipe clamps are easily available for all the diameters you can imagine, at least you will easily find a pipe clamp whose diameter fits the diameter of your motor.


 

 


 

Being powered from a 7.2V battery, the regulator U3 provides regulated 5V for the microcontroller and for the logic gates of the motor driver. You can add a capacitor between the output of the regulator and the ground to absorb the noise caused by the presence of motors in the system, but I didn't use any, and didn't face any problems regarding this issue.

Follower robot is a versatile platform that allows developments of various applications. The modern structure, we can easily modify the possibility of functions and add some our new functions. The price, the machine is a good choice for inventions and new applications in human life.
