Eu lucrez la un robot si m-am lovit de problema aflarii distantei dintre el si obiectele din fata lui. am auzit ca acest lucru se face cu diode IR. cam atat stiu de acest lucru. Daca are careva vreo schema sau ceva pls sa ma ajute si mine .Multumesc .

Se poate si cu ultrasunete (sonar), masoara timpul de la emitere la receptare, se imparte cu 2, se inmulteste cu viteza sunetului in aer => distanta. (un circuit simplu cu microcontroler si ceva condensatori).Transmiter si receiver US de 40kHz - UST40T si UST40R.Cu IR, GP2D masoara intre 4 si 30cm (max.80cm?), ultrasunetele cam intre 30 cm si 2m.

Am luat 3 senzori sharp gp2d12 , le-am conectat la un port AD de la pic 16f877a , problema esta ca valoarea lor este in schimbare continua si nu reusesc sa citesc o valoare stabila , chiar daca nu se shhimba distanta adica pun un obiect in fata si la iesire primesc o gramada de valori . As dori daca se poate o solutie : o schema , eventual ceva cod © .Multumesc anticipat .
