I have designed it just for fun and it’s my 1st Line Follower Robot . First I want to know how the line sensor work.
Finally I spent only USD $ 6-7 to build the robot.
There is no MicroController so we do not need to programm. I just used comparator IC using LM339, two H-bridge sensor using eight transistors FCS9013, and four transistors, FSC 9012. For the sensor you can use LED and LDR as the light receiver. I changed the LDR sensor to IR sensor.
I built this robot using only the analog comparator and IR sensor, no microcontroller. This is smart idea and very cheap approach.

Components:
R1, R7, R13, R14, R15, R16 – 330 1/4W +/-1%
R2, R3, R4, R5, R6, R8, R9, R10, R11, R12 – 10K 1/4W +/-1%
R17, R18, R19, R20 – 150 1/4W +/-1%
VR1, VR2 – 20K-50K
Led1, Led3 – LED(red) 3mm Led
Led2, Led4 – LED(green) 3mm Led
Optocoupler – 2 piece
Q1, Q2, Q3, Q4, Q5, Q8, Q9, Q12 – FSC 9013
Q6, Q7, Q10, Q11 – FCS 9012
U1 – LM 339
Battery 9 volt – 1 piece
Motor DVD dc 5Volt – 2 pieces
Tank toys for mechanic and wheel – 2 pieces
There are two line styles, white line on the black floor and black line on the white floor.
If you use black line on the white floor, you can set the robot if the Right-Sensor is on the dark side or black line and Left-Sensor is on the floor it will go to forward (by swap polarity of the motor). If the Right-Sensor is on the floor and Left-Sensor is on the black line it will go to backward.
That’s it… you can add wireless cam for to see how the robot walk… ^_^ Thank You
