java-player-users — General discussions on how to use Javaclient

Re: [Java-player-users] setPosition

[John O. <joh...@gm...>]

One thing that pops to mind is: I believe that type 2 subtype 2 means that
you are using the positional control method, as stated in the manual not all
drivers will support it
(http://playerstage.sourceforge.net/doc/Player-2.0.0/player/group__interface__position2d.html#ga16),
I dont know if its possible for the simulation to accept positional and the
real robot not, unfortunatley I deal only with simulation.  I would check on
the player stage forum to see if the pioneer can accept positional commands,
alternatively try using playerv to issue positional commands and if you get
the same error this is likely to be the problem.

Thanks

John

[Java-player-users] setPosition

[Matthias W. <mw...@gm...>]

Hi!

I downloaded the last version from SVN to have the setPosition Feature for
Position2DInterface.

When I test my program with Stage, everything works fine, and the robot
moves to the position, which was desired. On the other hand, when I try it
with Player and the real robot (Pioneer 2DX), the command fails and the
output of player2.03 is:

warning : Unhandled message for driver device=16777343:6665:4:0 type=2
subtype=2 len=28

Does anybody has an idea, how I could get it working?
Thanks!
Matze

Re: [Java-player-users] Position 2D - how to? - A newbie's question...

[Radu B. R. <ru...@cs...>]

You must check if the data is available/ready using p2di.isDataReady (see the API 
documentation for more information) and then print it.

We made some examples available some time ago on the web page. Those should run without 
any problems with the latest P/S/G versions.

Cheers,
Radu.

[Java-player-users] Position 2D - how to? - A newbie's question...

[Mark B. <mar...@gm...>]

Hi
I'm quite a newbie and I have a newbie's question about Position2Dinterface.
I'm using player-2.0.3 on wbr914 robot and I encountered some problems using
Position2dinterface.
I use the javaclient-2.0.1.jar
The problem is that I can't see position2D updates while reading the
position data in the infinite loop.
playerv works just fine...
I'm trying to do this way:


................

robot = new PlayerClient(ROBOT_IP, ROBOT_PORT);
p2di = robot.requestInterfacePosition2D(0, PlayerConstants.PLAYER_OPEN_MODE
);
robot.requestDataDeliveryMode(PlayerConstants.PLAYER_DATAMODE_PUSH);
robot.setNotThreaded();
p2di.setMotorPower(1);
while (runTest) {
 robot.readAll();
 positionTest(p2di); // this prints the position2d data on screen
 Thread.sleep(1000);
 System.out.println("=======================================");
}

Whats interesing that when I
run the playerv, subscribe to see the position data on playerv screen
and AFTER THAT run my simple program - I Do receive the updated data.
However when I make my robot move, the data reading fails (irrelevant data
is printed). I saw the code from the example (actually my code is c/p from
there... but it doesn't work...).
So could anyone please point me on my problem or provide some working code?

Any help is highly appreciated :)
Thanks in advance

Re: [Java-player-users] Gazebo is running strange

[Alexandre H. V. S. <ahv...@gm...>]

I'll try to make a movie with a digital camera, so the act of filming
doesn't interfere  the simulation.

On older tests  running only Gazebo works fine...

Again, thank you so much!!!

Re: [Java-player-users] Gazebo is running strange

[John O. <joh...@gm...>]

**In response to private message**

I think there are a number of things going on here.=20

First was it me but you were getting the same issues when you were not usin=
g
java at all.  At one point in the gazeboOnly video the clock stops at 59.2
for about 3 seconds for no apparent reason.  To me this seems to point to
some issue with gazebo/stage and not java.

Secondly I presume the stage video was running a simple algorithm but java
was consuming all the spare cpu time it could by the look of it.  Your
recorder program was taking 20%ish but if that was not there I think java
would have taken it anyway.  Having run it on my system with
runThread(-1,-1) it took 99.9% cpu usage, although it didn=E2=80=99t seem t=
o slow
the system down at all, java must do something a bit weird with its
yielding, to take 99.9% cpu time but not slow things down.  However running
with (1,-1) reduced cpu usage to 18%.  So I would probably recommend callin=
g
runTreaded with some reasonable values so that java does not do its cpu
eating thing.

However again I do not think that Java is the issue since the problem
appeared to exist in the gazeboOnly video too, its just more noticeable whe=
n
java is running, probably since java is taking more processing power.

Re: [Java-player-users] Gazebo is running strange

[Alexandre H. V. S. <ahv...@gm...>]

I changed my ' robot.runThreaded (-1, -1); ' to ' robot.runThreaded (100,
-1); ', as jugested John and I printed every sonnar read and position chang=
e
(with 'System.out.println()' ).

Gazebo still run 'jumping'...  :-(

The application is not reading and seeting position too much, its normal.

Java is consumming about 30% - 60% of CPU, wxGazebo about 4% and gazebo
about 7%.

I make other videos showing CPU usage with only Gazebo and with Java
applicatio.
Both can be found at
http://www.lsi.cefetmg.br/~ahvsoares/robotica/exemplos/OnlyGazebo.ogg and a=
t
http://www.lsi.cefetmg.br/~ahvsoares/robotica/exemplos/GazeboWithJavaApp.og=
grepectively.

The other videos also show CPU usage:

Just one remark here... if you are running in threaded mode, but you also attempt to read 
"manually" from your main loop, the read will return and do nothing, because:
---
public int readAll () {
   if (isThreaded) return 0;
...
---

Also the Space Wanderer example should contain a Thread.sleep () which assures that your 
main loop is not going to execute too fast.

Other than that, I agree with John that it would be good to view how much CPU time does a 
process consume. It might be Java but it might be something else as well. If it's running 
in Stage just fine, I think we are hitting a bottleneck somewhere (?).

Re: [Java-player-users] Gazebo is running strange

[John O. <joh...@gm...>]

My initial thought would be that looking at the code if you pass -1 to a
runThreaded then the PlayerClient will only yield in between each read()
function to the simulator.  This will then allow other threads to execute,
if there are none requiring execution then it will come back almost
immediately and issue another read(), this could then mean that you are
spamming the simulator with thousands of read requests a second, on top of
the read request that is in the main loop of the circleWalk. =20

This could be wrong, since after each read request it waits for a packet I
would have thought that this would act to slow it down since it cant issue =
a
new read until the previous has completed.  However I would try doing
something like runThreaded (100,-1), this will do 10 reads per second and
maybe also do a sleep in the main control loop to avoid spamming hundreds o=
f
commands to the position driver. =20

If this does not work try doing some print statements to figure out how man=
y
request/commands you are sending and also run "top" at the same time to see
how the processor and memory usage is, one problem with java is it does lov=
e
to eat memory.  I wouldn=E2=80=99t have thought it was memory as you are ru=
nning a
small program but looking at whether java, player or gazebo are using all
the cpu usage would be useful.

let us know the results.

Thanks

John

[Java-player-users] Gazebo is running strange

[Alexandre H. V. S. <ahv...@gm...>]

Hi, I'm trying do run a Java application with Gazebo and I noticed that the
execution of the application is making Gazebo be slow.

The robot is not showing a continuous movement, it is "jumping" along the
time. I have already noticed that the Gazebo timer (the time that is shown
on the interface) is stopping, the same as the robot.

Running " glxinfo | grep rendering " command I got " direct rendering: Yes =
"
.

I run the CircleWalk example (
http://java-player.sourceforge.net/docs/howto.pdf ) on Gazebo using
Javaclient and everything was right.

Looking the Wall Follower example (
http://java-player.sourceforge.net/examples/2.x/SpaceWandererExample.tgz ,
which were strange, with the robot 'jumping'), I saw a '
robot.runThreaded(-1, -1);' command.

When I put this command on CircleWalk example the same as Wall Follower
example occured... the robot started jumping...

So, I tried to remove the 'robot.runThreaded (-1, -1);' from Wall Follower
example and the robot stopped moving... the application only works with tha=
t
command.

I run the same application on Stage and all works fine.

Is there something I can do to make the robot movement continuous on Gazebo=
?

My computer is an Athlon XP 2400+, 512MB RAM, my video card is a GeForce4 M=
X
4000 AGP 8x with 128MB of memory.

Thanks.

[Java-player-users] Replay

[John O. <joh...@gm...>]

I have been trying to find a way of replaying a simulation so that I can
visualy see what happend during the simulation and havent found any way of
doing it.  I realise you can use the readlog to replay the sensor data and
feed it into your control program however havent seen a way of recording the
sensor readings and then using it to display a replay of it on player.  Am I
missing something or is this not currently possible?

I realise I could record a sequence of frames however this would slow my
simulation to a crawl and fill my disk up.

If its not possible is it something that others would find useful in the
future to be added?  I presume it would require a interface to each sensor
to tell the sensor what it is sensing then a program to read in a log and
feed it to the sensor.  Maby not the best of ideas to add a function that
tells a sensor what it is reading but does anyone else think some replay
method is worth while?

Thanks

John

Re: [Java-player-users] requestInterface() restrictions

[Jorge S. S. <js...@gm...>]

Hi all!

Concerning the requestInterfaceXXX methods...

I'm experiencing some troubles with the latest Player/Stage/JavaClient
CVS/SVN versions:

When trying to run a Stage simulation, methods
requestInterfaceSimulation
and requestInterfaceGraphics2D return null. If I try to debug by putting
a breakpoint, the process is then trapped before!, while requesting a
different interface: This happens in the requestInterfaceSonar method;
execution remain blocked in the read loop:

  while ((result =3D read (code, index)) !=3D PLAYER_MSGTYPE_RESP_ACK) loop.

I don't know if the problem comes from Stage, but as nobody has posted a
complain there, and playerv works, I suppose the problem can be in the
Javaclient2 (but cannot confirm).

Anyone else has experience something similar?

Thank you a lot
Jorge

Re: [Java-player-users] setPosition message format

[Radu B. R. <ru...@cs...>]

Hey John,

Just wanted to let you know that you were right, and that I fixed the bugs in SVN. It 
seems that I missed the definition change of player_positionXd_cmd_pos (velocity was 
added), therefore I did not upgrade the Javaclient classes. The bug was affecting all 
three position{1,2,3}d interface.

Thanks for the head-up!

Cheers,
Radu.

Re: [Java-player-users] setPosition message format

[John O. <joh...@gm...>]

Hopefuly I will get around to doing this at some point.  But I think it
should still exist as the Javaclient still only sends the position in the
latest svn version.  However looking at the P/S cvs repo I cant see the pack
functions that exist in the tar'd distrobutions(in the libplayerxdr
directory) the functiontable.c still refers to it but I cant find
it(player_position2d_cmd_pack) anywhere to verify that it is still looking
for a velocity command.

Anyway this may become clear once I get a chance to test it.

thanks again

John

Re: [Java-player-users] setPosition message format

[Radu B. R. <ru...@cs...>]

John, that sounds about right, but before I start digging and debugging, would it be 
possible to try it again using HEAD (CVS) Player/Stage and SVN Javaclient ?

There were quite a few bugs that were fixed in the repository since the last official 
version, and it might be that yours was fixed too.

If it still doesn't work, I'd be more than happy to fix it. Now if I could only make the 
day 48h instead of 24h, maybe I could write some documentation for it as well. ;)

Cheers,
Radu.

[Java-player-users] setPosition message format

[John O. <joh...@gm...>]

I have been having some trouble with getting setPosition to work on a
Position2DInterface.  (Player/stage 2.0.1 and Javaclient 2.0.1)

Taking a quick(well perhaps not that quick) look at the code in player the
pack function (player_position2d_cmd_pack) it appears to look for both a
position command and a velocity in the message:

...
  if(xdr_player_pose_t(&xdrs,&msg->pos) != 1)
    return(-1);
  if(xdr_player_pose_t(&xdrs,&msg->vel) != 1)
    return(-1);
  if(xdr_u_char(&xdrs,&msg->state) != 1)
    return(-1);
...

while the java version only sends the
position(Position2DInterface.setPosition), and from what I can tell this is
leading to my "warning : decoding failed on message to 4:1 with type 2"
messages.

Have I made a mistake here or is this something to be patched?  And is it a
player problem or JavaClient?  My instinct is that player should not be
looking for a velocity in a position command however I do not entirely
understand the P/S message formats and wanted confirmation that this was the
case(or not).

thanks

John

[Java-player-users] CameraInterface now works

[Radu B. R. <ru...@cs...>]

forgot to mention that I also managed to patch CameraInterface, and it now works (tested 
with different cameras as well as Gazebo).

[Java-player-users] Laser add-ons

[Radu B. R. <ru...@cs...>]

Just a small note people... I changed the structure of the PlayerLaserData class in SVN 
and added an array of PlayerPoint2d which basically represent the X and Y cartesian 
coordinates of a laser measurement. The calculations are done in LaserInterface 
automatically (borrowed from libplayerc) and they are accessible via 
<LaserInterface>.getData ().getPoints ();

Useful if you are doing 3D laser maps. :)

Cheers,
R.

well... really, I don't know.
The Stage driver is supposed to be fixed in the CVS, but maybe this

You mean the Javaclient interface for Speech using Stage, or in general, the speech

Re: [Java-player-users] requestInterface() restrictions

[Jorge S. S. <js...@gm...>]

wow!	Now it works fine! Thank you a lot

But it's very strange all the lines and points are drawn relative
to the robot position, instead of relative to the world coordinates
centre. I suppose this a P/S matter, so I will post there a question.

Just one bad new: the speech interface still doesn't work with Stage.

Hey Radu!
   Thanks for all your work today!  We'll get to checking it out early 
next week and let you know how things turn out.

Re: [Java-player-users] requestInterface() restrictions

[Radu B. R. <ru...@cs...>]

Fixed! Thanks for the notice. Initially, the Graphics2D support was broken in Stage so I 
had to do a dirty hack to get it to work. Since then, Richard fixed it, so it was about 
time that we fix it too.

You can get the updated code from SVN now.

Usage example:
		g2di.clearScreen ();
//		PlayerGraphics2dCmdPoints p = new PlayerGraphics2dCmdPoints ();
		PlayerGraphics2dCmdPolyline p = new PlayerGraphics2dCmdPolyline ();
		
		PlayerColor color = new PlayerColor ();
		color.setAlpha (0);
		color.setRed (0); color.setGreen (0); color.setBlue (0xff);
		p.setCount (200);
		
		for (double r = 0; r < 1.0; r += 0.05) {
			PlayerPoint2d[] points = new PlayerPoint2d[64];
		    for (int j = 0; j < 64; j++) {
		    	points[j] = new PlayerPoint2d ();
			    points[j].setPx ((float)(r * Math.cos (j * Math.PI / 32)));
			    points[j].setPy ((float)(r * Math.sin (j * Math.PI / 32)));
		    }
			p.setPoints (points);
			p.setColor (color);
			g2di.drawPolyline (p);
		}

Best,
Radu.

Re: [Java-player-users] requestInterface() restrictions

[Jorge S. S. <js...@gm...>]

Hi folks!

I have two troubles when using Javaclient2 with Stage:

 - I'm unable to draw anything with the Graphics2D interface (or I can't
see the effects)
 - The speech interface doesn't work with Stage (ok, this is not very
important at all)

I have noticed from the P/S users forum that the those problems are
solved in Stage,
so I guess the problem can be in Javaclient. Have anyone experienced
such problems?

I'm using CVS/SVN up to date versions of both P/S and Javaclient2

Thank you a lot
Jorge

Okay, fixed this one too (I think).

I am committing everything to the SVN now, so please check them out later and test to see 
if they work.

For Shawn: I added a few extra checks, so when you request a certain interface, Javaclient 
should never return another one.

Cheers,
Radu.
