The mobile line follower robot is a type of mobile robot with only has one specific task which is to follow the line made with black tape over the white background or vise verse. The LFR perhaps is one of the most popular robot build by the robotics, for more information please visit www.ermicro.com

boss can you get me the circuit and its components list. pls mail to: pdodlavssa@gmail.com
ADOREI SEU ROBÔ.PARABÉNS PELO VÍDEO!!!
very nice and simple, thanks !!
am facut acest robot si sincer merge!!! multumesc pt postare tino tot asa
@zaiban03329777747, Congratulate! You could try to experiment with 12 volt, pay attention to the transistor if it getting to hot than you have to lower the voltage. With more voltage means the LFR will run more faster and it could become difficult to navigate the black line properly.
@ermicroinfo where can i find geared dc motors?
From where did you get your dc motor?
@ermicroinfo i have made one and it is working beutifully thanks for sharing the idea and circuit , very simple circuit design….i have one more question can i use 12 v insteat of 5 v>>>.thanks
@asdfgghjklpoiuytr, you could always experiment with it
@ermicroinfo what if i use 9volt battery to increase torque and 2x 50k pots instead of 10k or something like that to control low the amperes?
@zaiban03329777747, yes you could add the LED, but only two LDR allowed.
can i use more leds if yes then it must be use on same transistor or system or build another symstem….
@asdfgghjklpoiuytr, there are two ways to increase torque, the first one is to use the geared DC motor and the second one to increase the DC motor voltage.
@ermicroinfo Any idea to increase the torque of the motors?
@asdfgghjklpoiuytr, you need to use the geared DC motor
@asdfgghjklpoiuytr, yes you could use it
Pardon me,i forgot to answer if the 3mm led for the sensor must be superbright(high intensity) or normal one.
I built it eventually,but i have some problems.First of all the dc motors(from a cd/dvd player) haven’t enough torque to move the whole vehicle when their speed is low.I used two white leds from a torch and i don’t now how many watts they are.The weaker light the better response?
Can i make any change to improve the torque without increase the speed?
@asdfgghjklpoiuytr, yes you can
Can i use 5mm white leds?
@karthik1065, no you can not.

@dyctvz, You could not use this circuit anymore, because most of 12 volt motor will draw more current that exceed the 2N3904 specification.
