problem with import lejoj.navigation.Pilot;

[faheim]

Hello
I found this code on http://lejos.sourceforge.net/nxt/nxj/tu ... hicles.htm on this address but there is some problem when I compile it, it gives an error that lejos.navigation does not exits. Any one has any idea, any kind of help will be appreciated.

CODE:

import lejos.nxt.*;
import lejos.navigation.Pilot;

/**
* Robot that stops if it hits something before it completes its travel.
*/
public class TravelTest {
Pilot pilot;
TouchSensor bump = new TouchSensor(SensorPort.S1);

public void go() {
pilot.travel(20, true);
while (pilot.isMoving()) {
if (bump.isPressed()) pilot.stop();
}
System.out.println(" "+pilot.getTravelDistance());
Button.ewaitForPress();
}

public static void main(String[] args) {
TravelTest traveler = new TravelTest();
traveler.pilot = new Pilot(2.25f, 5.5f, Motor.A, Motor,C);
traveler.go();
}
}


Thanks

Any one please.

The structure of the API is still evolving (often quicker than the tutorial!). Have you tried looking at the API documentation here:
http://lejos.sourceforge.net/nxt/nxj/ap ... mmary.html
You may notice that Pilot is now in lejos.robotics.navigation. You may also notice that it is now an interface. So you probably need to change the code to use a class that actually implements that interface... Another look at the doc would suggest that TachoPilot may do the trick...

Hello
Thanks you so much Andy. It is compiling now without any problem I am posting a changed code.

import lejos.nxt.*;
import lejos.robotics.navigation.TachoPilot;

/**
* Robot that stops if it hits something before it completes its travel.
*/
public class TravelTest {
TachoPilot pilot;
TouchSensor bump = new TouchSensor(SensorPort.S1);

public void go() {
pilot.travel(30, true);
while (pilot.isMoving()) {
if (bump.isPressed())
pilot.stop();
}
System.out.println(" "+pilot.getTravelDistance());
Button.waitForPress();
}

public static void main(String[] args) {
TravelTest traveler = new TravelTest();
traveler.pilot = new TachoPilot(2.25f, 5.5f, Motor.A, Motor.B);
traveler.go();
}
}

once agian thankyou so much:-)
