Yeah man! That was what I was looking for. Thanks!

Hello, I'm trying to use some functions of the MASTER_API with C/C++ but I'm not finding any references to that. I've already seen a lot of times the pythin code to do that but I'd like to know if there's a C/C++ code to access and use it. I've already know too that we can use XMLRPC, but I have no ideia how to implement that.

Any help will be appreciated!

Thanks!!

Hello, I'm trying to find the topics a common type. I've been doing some research and I found that, to use the "rostopic find " inside a program I need to use the XMLRPC slave/master. But i can't find anywhere more documentation about it. I've just found this one: http://wiki.ros.org/ROS/Master_API . I'd like to know if someone knows where I can find more exemples and information about how I can use it.

Thanks!

Thank you very much. I'm testing it and it is working until now. If I have more doubts I will be in touch! Thankss

I'd like to put some fields used in Imu msgs and GPS msgs in one message, like, mySensorsMsg. Did you understand? Maybe your first link will help me! Thanks!

Hello, I'm trying to combine 3 different msgs into a single one. I'd like to create a msg only with the fields required for my application and after that publish this msg into a topic. Anyone knows how can I do that? Thanks J.L.

I think that you should try to setup the mirrors. Try these commands:

sudo sh -c '. /etc/lsb-release && echo "deb http://mirror.umd.edu/packages.ros.org/ros/ubuntu $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'
wget https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install ros-indigo-desktop-full

I think that you'll be able to download and install de desktop-full version

Very Cool, but I'm trying with ROS Hydro and I cannot achive to have separete nodes for camera plugins. What should I do? Thks

Hello, I'm looking for a tool to establish a communication link between 2 or more robots in the Gazebo Simulator. I was thinking in a wireless module but I don't find anything like that. Any help will be appreciated. Thanks

You need to run, firstly, in a separate terminal the command

roscore

after that you will be able to run rviz and gazebo together without error

Att,

I've got the same problem and I've figured it out how to solve it. You are having this problem cause you don't have installed the controllers. Just run these commands in your terminal:

sudo apt-get update

sudo apt-get install ros-indigo-ros-control ros-indigo-ros-controllers`

After that when you try to run the same commands you'll be able to control the arm of rrbot.
