“JavaBot” LINE FOLLOWER ROBOT from Java, Indonesia
Tuesday, August 18th, 2009
The line follower robot with wireless video camera.
I have designed it just for fun. First I want to know how the line sensor work. I 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.
You can download this PCB FILE (ExpressPCB file)
Figure 1: main layout and sensor layout.
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
Figure2: JavaBot, my first line follower robot without the microcontroller.
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.
Figure3: Attach the wireless video camera to the JavaBot.
