Hi every one, I learned how to make a world in stage and add two robots to it. Now I want to use c++ code to move these two robots around. would someone please point me to the right direction. I basically have no idea how to do this. Regards, Shervin

Hi everyone,

I think I found the solution. If any one facing the same problem please fallow the below steps:

sudo apt-get remove gazeboX #X is the version of gazebo you installed in my case 5
sudo apt-get install libsdformat1

then you should be able to install indigo again

Hi everyone,

I installed ROS indigo first and then I tried to install ROS jade as well. I could install both ROS and switch between them successfully, However installation of jade totally replaced gazebo2.2 by gazebo5. Consequently I could not do any simulation in indigo. I decided to remove both ROS and Gazebo and reinstall the indigo, but I receive the below error when I try “sudo apt-get install ros-indigo-desktop-full”

Reading package lists... Done Building dependency tree        Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:

The following packages have unmet dependencies:  ros-indigo-desktop-full : Depends: ros-indigo-simulators but it is not going to be installed E: Unable to correct problems, you have held broken packages.

Thank you.

Hi everyone,

I am trying to generate a map in Gazebo, then use Gmapping package to generate a 2D map of the environment. I use indigo which utilizes Gazebo 2.2. I figured out a way how to do so through Edit → Building Editor. However, every time I try to save the map Gazebo crashes. Is there any way that I can make a map in any other software and then import it to Gazebo2.2. ( I know I can use Gazebo5, which make it easy to generate a map, but unfortunately Gazebo5 is not compatible with indigo)

Thanks, Shervin

Hi All,

I had ROS indigo on my system, then I decided to add the new version (Jade) as separate package. The installation was successful and now I have to folder /opt/ros/indigo and /opt/ros/jade. However, when I try to switch to jade by sourcing the “setup.bash” file I receive the fallowing error:

ROS_DISTRO was set to 'jade' before. Please make sure that the environment does not mix paths from different distributions.

Moreover it seems that Gazebo is totally is replaced by the new version. That prevents me from running the turtlebot simulation. I receive the below error by running the “roslaunch turtlebot_gazebo turtlebot_world.launch”

[turtlebot_world.launch] is neither a launch file in package [turtlebot_gazebo] nor is [turtlebot_gazebo] a launch file name
The traceback for the exception was written to the log file

Thanks Shervin
