Multi Turtlebot3 Simulation error about free_fleet HOT 20 CLOSED

Hey I also faced this error previously and I believe that it is due to the same problem : it seems that gazebo node is not publishing the transforms with the prefixes thus leading to a broken transform tree.

What I did as a quick fix (although I'm not sure if this is the best solutuion to this problem), was to add the prefix before the frames in the gazebo.xacro file which is passed in via the urdf.xacro file as shown:

<group ns = "$(arg first_tb3)">
    <param name="robot_description" command="$(find xacro)/xacro --inorder '$(find turtlebot3_description)/urdf/turtlebot3_$(arg model).urdf.xacro' botname:=$(arg first_tb3)" />

Hope this helps.

Hi @aaronchongth , yup I just did a fresh install using the instructions form the multi-robot-example branch and the multi turtlebot3 example worked fine!

from free_fleet.

Thank you for fixes and suggestions. I managed to get it working as well.

For those that stumble upon this topic, the rqt_tf_tree for a working run would look like this:

from free_fleet.

It looks like the target frames are not getting supplied. Could you post your rqt_tf_tree graph to verify?

I believe these issues arise from the fact that support for tf_prefix was dropped in noetic therefore, the simulation demos from turtlebot3_gazebo will not work as before. I have tested and got the demos working per normal by using these branches,

• ros/robot_state_publisher#139
• ROBOTIS-GIT/turtlebot3_simulations#131
• ROBOTIS-GIT/turtlebot3#681

Hello there @otomoov! Yes this is as I suspected, the errors you are getting as well as any additional warnings regarding tf, is related due to the issue mentioned above. For now, you can work with the above listed PR branches.

These errors are caused by changes in robot_state_publisher, that is still under discussion as mentioned in my previous answer. I would guess that this is due to not having set up a fresh workspace with these packages and branches yet, please rebuild your workspace with these instructions,

Solved. Thank you!

from free_fleet.

I had the same error as @otomoov but the above solutions by @aaronchongth didn't work....
It seems like the tf_prefix in https://github.com/rhaschke/robot_state_publisher -b noetic-devel is changed to
prefix_tf_with
editing the multi_turtlebot3.launch file inside the turtlebot3_simulations/turtlebot3_gazebo/launch directory
SOLVED the issue :)
Please update documentation regarding this.

from free_fleet.

Thanks for the heads up! I have made the changes as mentioned, #78. Cheers!

My rqt_tf_tree is as follows:

I've verified that the multi_turtlebot3.launch file is using prefix_tf_with, and that the robot_state_publisher is using the version with prefix_tf_with.

Am I missing something?

from free_fleet.

Thanks for bringing this up! The steps you have been following is correct, and I have managed to recreate the issue, we are looking into it now

from free_fleet.

Hello @lkw303! Thanks for your suggestion, you are absolutely right, it was due to the deprecation of tf_prefix, even on the side of the plugins.

In order to ensure the examples do not get broken again, I have tagged the specific commit before those changes on gazebo_ros_pkgs which should allow the examples to work in the future too.

I will continue to monitor the discussions regarding tf_prefix in noetic, and when it has been resolved I would hope to remove the use of those forked packages or specific commits.

Let me know if the fix works!

from free_fleet.

Thank you for fixes and suggestions. I managed to get it working as well.

For those that stumble upon this topic, the rqt_tf_tree for a working run would look like this:

could tell me exactly what you have done to get this

It has been some time since I did this so there might be some changes as to how the simulation is launched. For reference, the steps I used to launch the simulation can be found in #60 (comment).

As to how to get the tf tree, you might need to install rqt_tf_tree. On Noetic, this can be done with

sudo apt install ros-noetic-rqt-tf-tree

Followed by running

source /opt/ros/noetic/setup.bash
rosrun rqt_tf_tree rqt_tf_tree

from free_fleet.

Ive done the changes you mentioned in the launch, gazebo.xacro, and gazebo.xacro and my tree is still broken. I am spawning two turtlebots into the turtlebot3_world map. Ive attached a screenshot of the tree. I feel like it has something to do with amcl since i never see that broadcaster on my tree. The only way I can connect every tree is through a static publisher but I still run into issues with the wheel links

from free_fleet.

hello @jordanperrin! I'm not too sure if I can be of much help, since this is not exactly related to free_fleet, from what I see, it looks like the robot_state_publisher for your 2 added robots might not be running, or may have something configured wrongly. Could it be the namespacing/prefix you've applied to the new robots that were spawned?

from free_fleet.

I am still getting a broken rqt graph when running the multi turtlebot simulation.
Also when i am running source ~/ff_ros1_ws/devel/setup.bash , it is showing as there is no such directory.
I have tried re installing the whole package but no luck in getting this resolved.

The single turtlebot simulation works just fine.

from free_fleet.

<group ns = "$(arg third_tb3)">
    <param name="robot_description" command="$(find xacro)/xacro --inorder $(find turtlebot3_description)/urdf/turtlebot3_$(arg model).urdf.xacro" />

    <node pkg="robot_state_publisher" type="robot_state_publisher" name="robot_state_publisher" output="screen">
      <param name="publish_frequency" type="double" value="50.0" />
      <!--param name="tf_prefix" value="$(arg third_tb3)" /-->
    </node>
     <param name="tf_prefix" value="$(arg third_tb3)" />
    <node name="spawn_urdf" pkg="gazebo_ros" type="spawn_model" args="-urdf -model $(arg third_tb3) -x $(arg third_tb3_x_pos) -y $(arg third_tb3_y_pos) -z $(arg third_tb3_z_pos) -Y $(arg third_tb3_yaw) -param robot_description" />
  </group>

</launch>

I simply change the position of tf_prefix parameter outside robot state publisher node. That helped me to get each robot's namespace before framename. I additionally created a tfbroadcaster that publishes tf from map topic to each robot's odom frame. Now I am able to get rqt_tf_tree similar as @LKSeng got. Hope that helps
