thanks for your effort Ben, this start's out looking good! ;)
What is the current status of the conversion?

It seems that a significant part of the utility functions are still
missing, like most of the mass calculation function in body.cpp etc.
That's to be expected, as it's tedious work..

So to get to a working point fast and to make it easily testable and
hackable for a larger group of people I'd suggest adding the missing
functions as stubs, that just print out 'function blabla not implemented
yet!' in order to get it to compile. In this way you can see in the logs 
what's still missing when testing the system.

Further we should put it into a new CVS branch to make it easier to 
follow development.

An alternative might be to first refactor the existing
physics systems as a plugin first, move it into plugins/ and create the
the new PAL pyhsics system there as an alternative you can switch to. In 
this way the PAL pyhsics can stay in CVS head.

Markus

Hi, all:

  A draft hacking version of 'PAL' is uploaded here[1].

Please have a look if you'd like to, I think we

can make some dissusions about it ;-P

In past, I did some profiling (on my system with internal monitor) in 
which ODE was a bottleneck. But we had not tested ODE improvements and 
also we had no profiling under competitions conditions. Can anybody do 
the latter? Maybe we can ask the teams to do so!

If I remember correctly, there was some discussions about having 
different time steps for control and sensors. What do you think about 
that? Small time step for control commands and a bigger one for sensors? 
Or even some of the sensors such as the visual sensor?! (while it won't 
affect ODE processing much!)

Anyway, it seems that we should do something about network messages 
first! We might just compress the current messages using a compression 
algorithm (such as zip), or (as Carlos told me about) changing the 
format of the messages completely (serializing the current data objects 
as a binary stream (which might be compressed too)). Or there might be 
other solutions. What do you think about it?

Have a nice time,
Hedayat

To be honest, I think we first should make sure this is really the  
case. I mean, I suspect it, too, but we should do some profiling under  
competition conditions (i.e. in a network setting with external  
monitor and realistic agent binaries). This is the only way we can  
find out where the biggest amount of computation is really used. In  
the past, for instance, Zeitgeist was to a large extent responsible  
for slowing down the server. We addressed these problems in a number  
of ways, but we should make sure they are really fixed now. Another  
candidate for needing a lot of processing power is the generation,  
parsing, sending, and receiving of network messages. We have to look  
at all of these.

We also should try to determine how well the server runs with the  
multi-threaded timer and also using Hesham's ODE improvements which  
weren't used in Suzhou (as far as I know). These two things have  
potential to speed up the server considerably.

It depends on what part of the processing in a humanoid you mean. If  
it comes to control, 20ms is probably close to the upper limit I  
guess, otherwise your movements might get jerky. I remember in our old  
HOAP-2 robot, we had a dedicated microprocessor for the control that  
had a timestep of 1ms!

I can't really predict what the effects will be, but let's try ;-)

Thanks a lot for the input!

Re: [simspark-devel] good luck!

[Yuan X. <xuy...@gm...>]

Hi Joschka,

Thank you!

However, the game is somewhat unfair, because WE have to kill their agents.
I think they have a good team in their own test.
The problem about the server is that the network affects the timing.
The network in the venue is so bad that server always ran long step (
our agents print 0.04s per step ).
The best situation is that the simulation is not affected by the
hardware environment, however it is impossible.
May be we need a test agent or software to test the hardware, which
makes sure the server works fine, and then teams will not complain.
What do you think about it?

Hi,

I have checked the size of field and goal box, and draw boxes in the
monitor, it is OK.
I do not know why this happens, even I tried to increase the field
size, the problem is still there, very strange.

BTW: Have a good time in China.

Re: [simspark-devel] The bugs

[Sander v. D. <sgv...@gm...>]

Ok the goal bug hasn't been solved yet. In all occurences I have seen it
happens when the ball rolls into the goal right at the goal post. Could it
be that the bounding box ball is penetrating the side of the goal a little
bit, making the bounding box get outside of the goal? A solution could be to
increase the size of goal recording area a little bit at the side and back
of the goal, maybe by the ball radius. However, I have also seen it happen
that a goal is registered when the goal post is hit, this solution might
increase occurences of this bug.

Off to sleep again and test tomorrow..

Re: [simspark-devel] The bugs

[Sander v. D. <sgv...@gm...>]

Hey,

I wasn't very awake last night, I now see that that bug is already known :)
I have fixed one thing: the bounding boxes of StaticMesh nodes werent
updated after they were rescaled. So they were way too big for the agent
(and probably also the ball). I am trying to commit now, but it's going very
slowly. I think this solves most of the bugs: ClearPlayers works properly
again and I think it also solves the goal bug.

Sander

Hey all,

I haven't had time to look at these bugs yet, been too busy having a jet lag
and preparing for the competitions with my team :-) I will also try to have
a look at these tomorrow.

We also ran into another bug: twice so far the ball clearly rolled into the
goal, but a goal kick was given instead of a goal. I couldn't find the
source of this bug yet either, perhaps any of you know quickly where to
look, else I'll try again tomorrow.

See you soon at the competitions!

Hi all,<br>
I've added two new functions to GameStateAspect: SetTime &amp;

continue a game which was stopped due to server crash or something
similar. I thought that these might be useful. But if you think that I
should remove these please let me know.<br>

Another thing which we needed in IranOpen was the ability to start a
game with KickOffRight. At that time, I added a new KickOffRight

Hi,

Some phenomenon and possible reason are:
 * the clear player behavior is strange:
    - maybe because SoccerRuleAspect::ClearPlayers : the agentAABB is
not always correct
 * One team score the goal after the drop ball ( after the goal kick),
but the goal is not recored, the play mode change to 'goal kick'
again
   - the rule think the ball out of field but not goal sometimes, I
checked the code, it should works. The only change between 0.6 and
previous version is checkOnField do not use colliding test. A trick
solution maybe make the field a little bigger ( about the ball radius
).
 * The play mode is still `kick in' mode after the `RuleDropBallTime' passed
  - this should be fixed in my last change to the cvs
 * the 'b' (drop ball) is useless in 'kick in' mode
  - I do not know why.

I am sorry that I can not find time on them recently.
Hope you can fix them.
Thanks.

[simspark-devel] bugs of rcssserver3d-0.6

[Yuan X. <xuy...@gm...>]

Hi all,

There are some bugs in the rule aspect of rcssserver3d-0.6
Some people reported to me:
 * SoccerRuleAspect::ClearPlayers : the agentAABB is not always correct
 * One team score the goal after the drop ball ( after the goal kick
), but the goal is not recored, the play mode change to 'goal kick'
again
 * The play mode is still `kick in' mode after the `RuleDropBallTime' passed
 * the 'b' (drop ball) is useless in 'kick in' mode

I know you are all busy, but I hope you can get some time to help me fix them.
We are expecting the great game in Suzhou, right?
If you are glad to help, please let me know. Thanks.

Hey,

I just committed some changes to fix ball placement in goal kick sistuations
(and other drop ball situations inside the penalty area). Think it's good to
add these to 0.6.

[simspark-devel] OS of RoboCup 08

[Yuan X. <xuy...@gm...>]

Hi Sahar,

Which distribution of Linux be used in RoboCup 08?

I have noticed that the server need adding some header files in Suse 11,
since the c++ header dependencies have been cleaned up in GCC 4.3 .

This release is the final version for RoboCup 2008 in Suzhou China. It
is little different from version 0.5.9 in simulation, excepting some
changes for the rule of RoboCup 2008, including the vision perceptor.
And also, the eye-catching sky and goal are added. The monitor
protocol is improved due to the team requirement.

* Vision perceptor:
 The old vision perceptor (just the same as last year) is used for
 both Nao and soccerbot058.

* Eye-Catcher:
 - the sky box is added
 - the goal with net is added

* Monitor Protocol ( Thanks Carlos from Borregos3D):
 - Add 'move' command for setting the agent's position and rotation.
   The whole command may like this:
   (agent (team $teamname)(unum $id)(move $x $y $z $dir))
   where, ($x, $y, $z) is the desired position, and $dir is the

The agent doesn't beam then, just flies high into the sky, in the back of
the field. But in our case it is in a special situation, where play-on comes
straight after the beam. In other cases it seems to only happen when the
simulator is slowed down (skipping time messages).

For now I can only see the things I mentioned here. Oh and things like
colliders for the goals and field side :). I agree we shouldn't wait with
the next version, just make sure teams know these bugs will be out of the
server in suzhou.

[Sander v. D. <sgv...@gm...>]

Hey,

Earlier I suggested 0.00001-0.00005 (in the thread on rules for Suzhou), so
I think 0.00005 is a good one ;-) it looks like the agent will be able to
kick about 6-8 meters far with those parameters, which I think is a nice
distance to promote team play.

Re: [simspark-devel] preview of rcssserver3d-0.6

[Feng X. <hen...@ma...>]

Hi Sander,
 
About the ball parameters, I set them as the field is 6m x 4m.
I think it should be adjusted. And, I suggest 0.0001~0.00005.
(current value is 0.0005).

Hi,

At the moment the server still has the following issues:

- the bug that agents are launched into the air when initialized. I havent been able to create a situation in which this reliably happens, but it happens regularly on some systems. Other teams have reported this too
- the ball parameters are way too strict for the Nao, it won't roll further than half a meter or something

Just to indicate there will probably have to be made more changes before Suzhou, so this may not be the final version (before teams panic about this ;) )

Other than that: very good work!

Will the agent beam to their position then?
Note that the Nao is assembled in (0, -1, 1.5), so if the agent is in
that position, I think it is OK.

Maybe you can gave good parameters ;-)

Do you think what to be changed?
Note that we are later to make the final version according to the schedule.
I think teams panic about uncertain of the server.
