-
Instead of running gazebo as a client and server cold be better to use gzserver alone because the first time you run gazebo takes a long time to start the master because the server is downloading the models.

Add the message_generation dependency to the find package call which already exists in your CMakeLists.txt so that you can generate messages. You can do this by simply adding message_generation to the list of COMPONENTS such that it looks like this:

Al ejecutar este comando tuve algunos errores, primero no encontraba el archivo SDF, eso ocurría por la falta de llamar al setup.sh de gazebo. Una vez corregido eso me topé con este error: Error [Plugin.hh:126] Failed to load plugin libhello_world.so: libhello_world.so: cannot open shared object file: No such file or directory No tengo tiempo de revisarlo ahora, pero pondré la solución en cuanto la tenga.
-
El último error descrito ocurre por ejecutar el comando en una terminal en la que no se ha exportado la variable GAZEBO_PLUGIN_PATH, una vez exportada la variable todo funciona según lo esperado.

Remove ROS's Old Version of Gazebo If you have previously installed ROS's version of Gazebo through the ROS debians, remove them now by running either of these: sudo apt-get remove ros-fuerte-simulator-gazebo sudo apt-get remove ros-groovy-simulator-gazebo

Estas instrucciones son nuevas, en la versión 1.8 de estas instrucciones no se indicaba nada sobre la desinstalación.
-
-
-
Esta es otra de las instrucciones nuevas en esta versión de la wiki, la instalación debe hacerse compilando el código, al menos hasta que Gazebo 1.9 sea liberado (se espera se libere en verano de 2013)
-
-
rosrun gazebo_ros gazebo
-
Estas instrucciones tendrían el mismo problema descrito en las notas a la wiki 1.8 con el mismo nombre, sin embargo en la versión 1.9 se menciona que se debe compilar desde el código, y bajo esas condiciones seguramente sí funcionaría.

rosrun gazebo_ros gazebo

This line does not work. The script called with this call have many issues. The first is a call to a unavailable script in /usr/local/share/gazebo/setup.sh, it does not work because there is no file there. The setup file in my installation points to /usr/share/gazebo/setup.sh
-
I have tried to fix the problem with the "correct" environment variable, but after searching I found that there is no environment variable of the installation folder available
-
-
rosrun gazebo_ros gzserver
-
The same problem described before, they search for a setup script in the wrong location.

Setting the update rate to be one over the time step will force Gazebo to run no faster than real-time.
-
Me llama la atención que mencionen que el "update rate" establecido a 1 haga que la simulación no vaya más rápido que el tiempo real. Yo entendería que update rate se refiere a cada cuánto se actualiza el modelo, no la velocidad de ejecución. Tal vez estoy mal interpretando la frase en el tip.

-
Move to, Delete, Control Joints. The first moves the view to be directly in front of that model. The second option deletes the model, and the third provides information on joint control.

These parameters appear in the bottom half of the Tree when an item is selected.

Las propiedades podrán ser modificadas hasta la versión 2.0 de Gazebo, por ahora sólo es un elemento de despliegue de la información

SDF 1.3 reference.
-
Ya que la versión más nueva de SDF es la 1.4 y es la usada por la versión más nueva de Gazebo, creo que sería apropiado que el tutorial se basara en SDF 1.4

A bash script is installed with Gazebo that will set these environment variables to defaults that will work in most cases:
-
As mentioned in other note, I think is preferable to source the script of the specific version, instead of this .sh that searches all the available setup scripts and sources the newest.

parses a world description file given on the command line, and then simulates the world using a physics and sensor engine.

gzserver
-
First time you execute gzserver, it could get the models from internet, and it could take some time.
-
Cuando ejecuté por primera vez el servidor de gazebo comenzó a descargar los modelos y nunca me avisó de que había terminado. No sé si debía esperar más o es un error común en el software, por favor retroalimenten qué les pasó a ustedes.
-
-
you can launch the client and the server with a single command:
1.5/install - Gazebo Wiki - 0 views
-
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu precise main" > /etc/apt/sources.list.d/ros-latest.list'
-
Already done if you have previously installed ROS through aptitude (apt)
-
-
The pre-compiled binaries install in /usr/bin/gazebo. By default, source installation will be performed in /usr/local/bin/gazebo. If you install the pre-compiled binaries on a system that has gazebo installed in /usr/local/bin, YOU MUST REMOVE gazebo from /usr/local (otherwise the os will try to load dynamic libs from your source install into your pre-compiled gazebo). It is a good idea to consider using CMAKE_INSTALL_PREFIX to install your compiled version in a different directory than /usr/local.
-
. /usr/share/gazebo/setup.sh

First time you execute this script it could take some time. If you add the script to your .bashrc file, the first time you open a terminal it could take some time to start.

-
Esto no funciona, el paquiete turtlesim_navigation no existe en Fuerte o Groovy.
-
Al comentar estas líneas el programa se ejecuta, pero se queda en un bucle infinito.
-
Después de instalar ros-fuerte-turtlebot-apps el problema se resuelve, pero aparece otro, un ciclo infinito con el mensaje: Warning [RaySensor.cc:206] ranges not constructed yet (zero sized)
-
In ROS Answers we can get some help about this issue: http://answers.ros.org/question/38826/turtlebot-simulator-not-working-correctly/ I'm just testing if it works with this modifications
-
After testing all the recommended steps, and checked that the patch mentioned in some of the forums are applied. I don't know which solution can I apply.

The output of the command is really different, at least in groovy.

If rosbag play publishes messages immediately upon advertising, subscribers may not receive the first several published messages. The waiting period can be specified with the -d option.
-
You can have rosbag play not start at the beginning of the bag file but instead start some duration past the beginning using the -s argument.

Sería interesante probar si al dar un parámetro inexistente devuelve un falso o crea el parámetro como lo hace el getParam usado desde línea de comandos.

I guess param is more close to the getParameter command, because in case it can not be retrieved, it is created.

If `rosparam set` is called with an unexisting parameter it creates that parameter, so be careful when writing a parameter if you expect to get the desired function.
