Hi, Sir, I am asking help.
I want to simulate what I learned in this course with my own computer.
With the URDF file, I succeed the command “roslaunch rbkairos_moveit_config demo.launch”.
But… when I command “rostopic list” it is different compare to when I tried at ROS IGNITE.
I could not see /robot/prefix and topic regarding arm.
And In my gazebo, there is nothing
(compare to ROS IGNITE, there is rbkairos-ur5).
Would you help me to run this program at my own computer?
Hello @hki,
Have you installed and launched the RBKairos simulation in your computer? Here you have the repository with the simulation packages: https://bitbucket.org/theconstructcore/rb_kairos_sim_new/src/master/
You will need to download the simulation packages into your workspace and compile it. Once everything is compiled, you will be able to launch the Gazebo simulation with the following command:
roslaunch rbkairos_sim_bringup_new rbkairos_complete.launch
Best,
Hi Sir,
I just followed your guide, but guess something is missing…
Would you let me know what is missing from mi side?
I just want to simulate same program at my own computer.
Hi Sir,
Sorry but as I am still working this problem.
Would you help on this?
Hello @hki,
From the error message, it looks like you don’t have the summit_xl_gazebo package. You would need to download it and compile it in your workspace. You can try to use our own version, which you can find here (make sure to use the branch kinetic-gazebo7): https://bitbucket.org/theconstructcore/summit_xl/src/kinetic-gazebo7/
Best,
Dear. Sir,
Thank you for answer. 
After I launch with the command, it works.
But unfortunately, I could not fine arm_controller topic with the command.
What is needed more if I could play the same course on my local computer?
Hi, I’m in the same situation as the latest comment of @hki
I already installed and compiled the packages mentioned above:
https://bitbucket.org/theconstructcore/rb_kairos_sim_new/src/master/
https://bitbucket.org/theconstructcore/summit_xl/src/kinetic-gazebo7/
And the “roslaunch rbkairos_sim_bringup_new rbkairos_complete.launch” works.
But the “arm_controller” or “robot/arm_controller” topics aren’t listed so I can’t move the “real” (simulated) robot when I make the execution trajectory whit moveit.
Hope you could help me, many thanks!

Hello @albertoezquerro ,
Yes, there are a few errors and warnings, but I don’t know how to solve them.
This is the output when I type “roslaunch rbkairos_sim_bringup_new rbkairos_complete.launch”:

As you can see, there is no “/robot/arm_controller” so I can’t make the motion planning.
Thanks for your time!
What ROS version/Gazebo are you using?
I’m so sorry, I didn’t get notified about your reply!
I’m using ROS Kinetic 1.12.17 and Gazebo 7.0.
I want to update the question: I have download the packages from this other repository this time, and now it seems to work fine.
But from the previous packages also found another problem: the laser didn’t read anything (-inf). Just saying if you want to check it, but is not needed with the new download.
Now I’m having problems with another theme, just in case you could have a look at this new question.
Thanks for your time and sorry for not replying earlier!
