Try this (leJos):
import josx.platform.rcx.*;
import josx.util.*;
import josx.robotics.Navigator;
public class Test
{
public static void main (String[] arg)
throws Exception
{
int size = 100;
Navigator nav = new
RotationNavigator( ( float)8.5, // wheel diameter in cm
( float)10.5, // track in cm
( float)5.0); // gearing ratio between
// wheel and rotation sensor
nav.gotoPoint( size, 0);
nav.gotoPoint( size, size);
nav.gotoAngle( 0);
nav.stop();
System.exit( 0);
}
}
