Line follower bot

Hey everyone!

I'm new to LMR and I'd like to post my first robot. It is a simple line following bot. It can follow a black line on a white background and vice versa.

These are the parts I used:

• ATmega8
• 2 hacked Servos
• 3 CNY70 reflex optocouplers
• 1 74HC14 schmitt-trigger

I built the robot because I got fed up with the other robot project I worked on and I wanted to get some kind of robot going. The idea of a line following robot seemed very simple. Just hook up 3 CNY70 to a schmitt trigger, connect this to the microcontroller and then let the microcontroller decide wich way the robot should go.

The robot needs a little more tweaking but actually it's pretty good at what it is supposed to do

Tell me what you think :)

So long
