Line Follower Robot

Last week I’ve just made a simple line following robot. So I want to share my experiences to you all. Especially electronic freaks and robot fans I say simple because it’s really so. Me and my friends (Setyo and Awal) just need 3 days total in building the robot.

Basically, just head to this page, it will help you with most of the basic theory needed for building the line follower. But I didn’t follow all the designs. I used a tank platform here. But I used project boards here. no PCBs. And there’s just a little difference in the mechanical design. The controller and everything’s just the same. But there are some schemes that will not work there. I’ll explain them and the way to debug.

First, the sensory scheme is not working with me. The receiver IRs won’t work. I dunno why. But I’ve made a little improvisation and it works. This is the scheme. Actually this is the sensory scheme from http://www.kmitl.ac.th.

Second, the program sourcecode will not work in Keil, so if you’re using Keil, you should compile this modified sourcecode.

If you do everything that is stated there and follow my debugging process, I think you’ll succeed.

Here is the pictures from my robot. His name’s Gugun

And here is the sensory circuit (it’s on the bottom of the robot)

Anyway, good luck to all of you who want to make this thing
