下面是第1行到第10行。我正试着把速度提高到100。但是我找不到合适的比例。

我个人没有在NXT上使用过一个以上的光传感器来跟踪光线。但是你应该能够在一个传感器上获得一个不错的速度。下面我将尝试解释如何执行此操作的代码。

(我不太熟悉用于NXT的RobotC，对不起！)

float diff; // change this to float
long redValue1;
long greenValue1;
long blueValue1;
long redValue2;
long greenValue2;
long blueValue2;

float kP = 0.5;
long targetSpeed = -30; 
long targetGreenValue = 67;
// I don't know what this value should be. I suggest approximately 2/3rds toward white.
// If fully black = 0 and fully white = 100, then I would try 67.

task main()
{
    repeat(forever)
    {
        getColorRGB(S1, redValue1, greenValue1, blueValue1);
        diff = (greenValue1 - targetGreenValue)(float) * kP;
        motor[motorA] = targetSpeed - round(diff);
        motor[motorB] = targetSpeed + round(diff);
        delay(10); // This is milliseconds, right?
    }
}
