This is my first attempt to build a line-following robot after reading David Cook's book "Robot Building for beginners".

  • @technology49 ναι.

  • nice can you please tell me that had you used microcontroller or what?Please

  • @mohsenhsp I haven't used a microcontroller, although i could use one. The robot runs only with a LM393N voltage comparator chip fed by 2 photoresistors.

  • what motors u use?? cause i use L293D IC for high current...but till my car wont move....must have been problem is in the motor

  • I'm not into robotics yet, but when I get back to the States, I think I'll start. I wanted to ask, is there any way for you to reduce or eliminate the negative feedback here? I don't have a better term for it than that... he turns left, the straight line looks like it's to the right, he turns right, the line looks like it's to the left, and he wiggles back and forth without ever straightening out. It looks like there's only a binary switch between the left and right wheels. Any ideas?

  • @christsiav hmm.ok thanks
