I know this is probably a newbie question...
I am trying to get the following "line-follower" program (or motors A and C)
to stop after 60 seconds to measure the distance traveled in a minute. What
would be the simplest way to do this?
All suggestions would be greatly appreciated!
~Arnold~
This the program I am using:
---------------------------------------
import josx.platform.rcx.*;
public class FollowLine
{
public static void main (String[] arg)
throws Exception
{
Sensor.S2.activate(); // turn on the sensor light
Thread.sleep(300); // wait for reasonable sensor
values
int threshold = Sensor.S2.readValue(); // read light-threshold
LCD.showNumber(threshold);
while (!Sensor.S1.readBooleanValue()) // loop until robot touched
something
{
Motor.A.setPower(7);
Motor.C.setPower(7);
Motor.A.forward(); // go forward for 100
milliseconds
Motor.C.forward();
Thread.sleep(100);
if (Sensor.S2.readValue() > (threshold + 10)) // examine the
black line
{
Sound.beep(); // beeps once
Motor.A.backward();
Motor.C.forward(); // turn a little bit left
Thread.sleep(120);
} // end if
} // end while loop
} // end main()
} // end Class
