Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1:

Let's make a fully autonomous robot using Arduino and IR sensors. It can follow a black line on white surface. Watch video for more!

Components used:
1- Piece of cardboard/ Acrylic sheet

2- Arduino Uno :

3- IR sensor :

4- BO motor :

5- Wheels :

6- Caster wheel :

7- L293d IC:

8- Zero PCB:

9- Flexible wire:

10- Battery:

Fix all components on acrylic sheet and make a chassis as shown in pictures.

Step 2:

Now make all connection As per the circuit Diagram bellow. you can make this circuit on dotted pcb like this. or can use this type of professional looking PCB.

you can order PCB for this Shield from here

or for ready made shield contact us on:

Now it's time to program this robot. upload this program to arduino and all done.

download code from here:
