Hi folks, I got yarpview installed now after set GUIS option on ccmake environment. Thanks!!!<br><br>Looking at Makefile to compile cpp files I saw the variable ROBOTPKG_BASE point to HOME/openrobots. I don't have this dir but "googling" it I found the following site:<br>
<br><a href="http://softs.laas.fr/jrl/hppDoc/share/doc/hppDoc/hppdoc_howtoinstall.html">http://softs.laas.fr/jrl/hppDoc/share/doc/hppDoc/hppdoc_howtoinstall.html</a><br><br>Should I install it? Is it really necessary?<br>
<br>Just to tou know, I work at CEASB: <a href="http://www.pti.org.br/ceasb">http://www.pti.org.br/ceasb</a> and there we intend to construct a robot to inspect the huge wall form ITAIPU dam (<a href="http://www.itaipu.org.br">www.itaipu.org.br</a>). I studying some possibilities and Blender-Robotics looks good to simulate this task. What you think? I'm gonna work on control project but I'd like to know how get 3D simulation working.<br>
<br>Thanks for all.<br><br>Breno<br><br><div class="gmail_quote">2010/1/22 Gilberto Echeverria <span dir="ltr"><<a href="mailto:gilberto.echeverria@laas.fr">gilberto.echeverria@laas.fr</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Hi Breno,<br>
<br>
It is true that there is not much that can be done with the simulator
at the moment. But there are a few things you can try.<br>
In the directory $ORS_ROOT/clients/atrv there are a few C programs that
connect with the simulator, to send commands to the robot. You can
compile those programs, and then run them with the appropriate
arguments:<br>
<br>
<tt>atrv_destination-1.0</tt> You run this program with the name of the
robot you want to control as the first parameter. The default name of
the robot is the example files is ATRV (the name of the object
representing the robot chassis). But you have to add the letters OB
before the name of the robot when referring to an object in the Game
Engine. For example, you can run the program as:<br>
$ $ORS_ROOT/clients/atrv/atrv_destination-1.0 OBATRV<br>
Once the program is running, it will ask you for the coordinates where
the robot should go. You enter these as three floating point numbers,
separated by spaces. When you hit ENTER, a marker will move to that
location, and the robot will move near it. The client program can also
read information from the robot. At the moment it reads its location
back, but it can read the output of any of the sensors installed on the
robot, simply by setting it to read the appropriate yarp ports.<br>
<br>
<tt>atrv_dest_cams-1.0</tt> Works nearly the same, but it also takes a
second argument, which is the number of cameras on board of the robot.
To use this example work, you will need yarpview working, and opened to
listen a port with a name in this format:
/img/[robot_name]/[camera_name]<br>
For example, you'll open yarpview as:<br>
<tt>$ yarpview /img/OBATRV/Camera1</tt><br>
And then run the client program as:<br>
<tt>$ $ORS_ROOT/clients/atrv/atrv_dest_cams-1.0 OBATRV</tt><br>
>From this point, the client program works the same as <tt>atrv_dest_cams-1.0</tt>.
The difference is that in Blender you can now press the spacebar to
toggle the image stream to yarpview on and off. In the yarpview window
you'll see the image captured by the camera on board the robot.<br>
As you have seen, pressing the arrow keys in one of the examples makes
the man move. It is set as the target of the robot in that file. So
when you input coordinates for the new destination, the man will
teleport there. However, while the robot is moving, you can move the
human and have the robot chase him.<br>
<br>
These are still only test programs to try the communication of the
simulator with external modules. Eventually we'll connect the
simulation with the real control systems of the robot.<br>
<br>
Try these programs out, and let us know how it goes. Cheers.<br><font color="#888888">

I installed yarp following INSTALL file but I didn't get yarpview
installed. I think it's fundamental to get properly advantages from
some examples.<br>

Nicolas, thanks for your support. I did all recommendations listed
INSTALL file inside /ors dir. That means that my blender is 2.6, my
python is also 2.6 and ACE is 5.6.3 I got ors file with bzr command

Hope I get it through to you!!!<br>

Hi,<br>
<br>
Could you check if you have the blender 2.49 for python 2.6 because
there is also blender 2.49 for 2.5 ?<br>
But I don't think the problem from this... Could you give us also the
repository version you have ?<br>

<div text="#000000" bgcolor="#ffffff">Hi Breno,<br>
<br>
I just tried to find out what could be the problem, and honestly I
couldn't make that code work myself. The blender file you are using is
a bit outdated now, since we have made lots of changes to the whole
framework. Our yarp-blender bindings have changed a lot, and so, they
don't work anymore with this file.<br>
<br>
Can you try downloading the latest files from:<br>

I was looking for middleware.yarp but I didn't find it yet. Another
issue is why I can't edit Yarp_python_simulator.blend file. I mean I
tried to change some pieces of code but It's not allowed to change
anything. Do you have any idea about it? My python is 2.5.<br>

Breno,<br>
<br>
Did you copy the yarp.py and _yarp.so ? Do you have the same version of
python to run blender and for yarp-python ? It should be python 2.5 or
2.6.<br>
<br>
$ sudo cp yarp.py /usr/lib/python2.5/site-package/<br>
$ sudo cp _yarp.so /usr/lib/python2.5/site-package/_yarp.so<br>
