  1. A

    Деда, он опять налево уехал! Завтра соревнования, а он у нас по линии ехать не хочет.

    Grandpa, it's gone off to the left again! The contest's tomorrow, and our robot won't follow the line.

  2. B

    Не паникуй. То, что он всё время уходит влево, значит, что один из датчиков не видит линию.

    Don't panic. The fact that it keeps drifting left means one of the sensors isn't seeing the line.

  3. A

    Я их уже три раза проверял! Может, программа неправильная, и надо всё переписать?

    I've checked them three times already! Maybe the program's wrong and we need to rewrite the whole thing?

  4. B

    Переписать всегда успеем. А не может ли быть, что левый мотор просто крутится медленнее?

    There's always time to rewrite it. But couldn't it be that the left motor is simply turning slower?

  5. A

    А как это проверить, чтобы не разбирать его целиком?

    And how do we check that without taking it all apart?

  6. B

    Дай-ка мне тестер и лупу. В моё время мы приёмники на коленке собирали, а тут всего шесть проводов.

    Hand me the multimeter and the magnifying glass. In my day we built radios out of odds and ends, and here there are only six wires.

  7. A

    Ну что там? Ты уже десять минут молчишь и только хмыкаешь.

    Well, what is it? You've been silent for ten minutes, just going "hmm".

  8. B

    Вот он, голубчик: провод от левого мотора еле держится. Пропаяю, и поедет по линии как миленький.

    There it is, the little rascal: the wire from the left motor is barely holding on. I'll solder it, and it'll follow that line like a good boy.
