Hello
I've built a line follower which is quite fast (approx 4 secs per lap on
the testpad). It consists of two motors, each powering a 2/3 geared large
wheel. Two light sensors are attached to the front pivot wheel. The
distance between the sensors are 5 "lego units".
My problem is the program. I think it's too "uncomplicated". I guess i
could do more out of it, but i'm not a very good programmer.
Any suggestions to improvements in the program is appreciated.
The program:
#define white 41
task main() {
SetPower(OUT_A + OUT_C,8);
SetSensor(SENSOR_1,SENSOR_LIGHT);
SetSensor(SENSOR_3,SENSOR_LIGHT);
while(true) {
while(SENSOR_1>white && SENSOR_3>white) {
OnFwd(OUT_A + OUT_C);
}
while(SENSOR_1<white) {
Off(OUT_A);
Wait(2);
OnFwd(OUT_A + OUT_C);
}
while(SENSOR_3<white) {
Off(OUT_A);
Wait(2);
OnFwd(OUT_A + OUT_C);
}
}
}

| In Creative Projects I make recommendations on line followers. One of them is to add a touch sensor that you can use as a trigger to grab the light levels of the line and the surface and store them in memory. Then you can use the average of those (...) (23 years ago, 2-Apr-01, to lugnet.robotics)

| (...) I've built a few line followers to see how fast I can do the test track - but I've concluded that you have a quality/speed tradeoff. I've built robots that *approximately* follow the track at these kinds of speeds - but without some kind of (...) (23 years ago, 2-Apr-01, to lugnet.robotics)
