Line Follower using IR sensors (no microcontroller)

Let's Make Robots Robots
1

Hello there LMRians!!! Here is my first robot. This is an LM324 comparator based line follower robot. It uses a pair of analog IR sensors. A power supply board consisting a 7805 IC has been used. The chasis was from an old toy car. The L293d motor driver has been used for driving the motors. It is logic based and makes no use of a microcontroller. Enjoy

Follows lines using IR sensors

  • Actuators / output devices: Gear motors
  • Control method: Infra Red
  • CPU: LM324 comparator
  • Operating system: none
  • Power source: 1.2v Ni-Cd x 6
  • Programming language: none
  • Sensors / input devices: Analog IR Sensors
  • Target environment: indoor

Moar Speed :smiley:

Nice going!

thankyou birdmun…actually

thankyou birdmun…actually i had made this one a year ago…i will post a couple of arduino ones now…

and i am trying to make use of more comparators to handle more sensors using LDRs…for better control and speed

Please more in formation.

Please more in formation. Since I am also in analog circuits (see my ALF) I wantr to know how you did it. Circuit diagram and some more good pictures would do it. Oh yeah…before the otehrs complain…a video is a must :-)))

I am really looking forward

I am really looking forward to that lumi…just got some exams these 2 weeks…i’ll try my best…:slight_smile:
