Obstacle detection circuit

with 9 comments

In any robot design, obstacle avoidance is a very important part of design. I was planning to make my own sumo robot, and i think that the object (or oponent) perception can be done with the fabulous LM567C – Tone Decoder. The circuit can be seen below:

The circuit worked perfectly in my breadboard. Over the next few days I will make a pcb. See it:

  4. Hi, pls i need your help.
    In your project i’ve noted some changes from the electrical and pratical scheme (es.PIN 4 used for led modulation instead the 5)
    Can you tell me what’s the final configuration used?

    • Hi Lemorlenny,

      I think you made a little mistake (and the photo don’t help so much…).

      See my Flikr photos again and pay attention on notes. I’ve added more notes to show where the resistors are connected.

      Thank’s

  5. Thanks for your reply Rodrigo.

    My bad, I wanted to write too quickly!
    At this momemt i’m without 2N3904 and the LPT80A, i tried other similar component without success, tomorrow i’ll go to find it. (all capacitors are .1uF and 1uF right?)

    Thank you
