Robot Car Tracking Line [ Easy Way ]





Introduction: Robot Car Tracking Line [ Easy Way ]

This instructable gives instructions for constructing a robot car that will tracking dark line ( black )

robot Car contain ( IR sensors) and when sensors on black line , (sender IR) send infrared but not received it on(emitter IR) here both of wheels continue running forward , but when car go out the black line, sensor send and received (IR) here the left wheel opposite his direction to backward , and car carved.

Step 1: Equipments

1.Inverter 74LS05N
2.Relay 5-6 V
3.Transistor 2n2712
4. 4.5 Volt battery to motors and 6.0Volt to circuit
5.Two motors
6 .Wires
7. (IR) emitter, receiver
8. Board
9. Resistances (R1=6.2 M Ω, R2= 82 Ω, R3=10KΩ )

Step 2: Construction

connect the circuit as shown in figure

also sometime you need to add black tube in IR receiver ( more accurate in response )

Step 3: Done

here is the video

also you can be more creative by replace IR with microphone for example or anything

    Can tell me about how to Wire it or simply i want Wiring

    what are the RPM of the motor

    please tell me guys how connections are made with the relay..

    If I'm not mistaken, as I can see the circuit it only turns to the left... was that on purpose?

    Hi,only one question!

    What are the RPM of the motor.

    can you show how you have placed the reciever, im trying this , But its not working...please help me...i need more details about the type od IRx,Tx used,

    When i tried it, the reciever voltage is not varying by much while it is in contact with black or white surface...
    please help me...

    Hi, nice robot! Very simple to make!
    I want to make one but I have only 1 question:

    What does de inverter do?
