Hi @kalkimann ,

Are you working with a specific rosject?
It’s important to make sure you have your ROS workspace compiled and sourced after it.

Let me know if you have problems trying to do that

Regards

catkin_make didn’t help… details below … rebooting n retesting

Rosject - Multiple Robots Navigation

cd simulation_ws/
catkin_make
source devel/setup.bash
echo $ROS_PACKAGE_PATH
/home/user/catkin_ws/src:/home/user/simulation_ws/src:/home/simulations/public_sim_ws/src:/opt/ros/kinetic/share
roslaunch multiple_turtlebots_sim main.launch

Sorry No joy … still … ResourceNotFound: tiago_gazebo

I see. Could you share the rosject with me by e-mail?

emailed “multiple_robots_navigation” rosject.
Also, a second error,
$ roslaunch multiple_turtlebots_nav navigation.launch

another Error in same Rosject:
ResourceNotFound: turtlebot_navigation

Hi @kalkimann

I’ve received but I need the rosject share link, please

It will provide me the whole environment so I can reproduce

Waiting for your e-mail

Cheers

The problem is, since the rosject is a little bit old, the simulation is trying to launch a world from a package that doesn’t exist anymore (tiago_gazebo). The code that launches the simulation is the main.launch file as follows:

<launch>
  <param name="/use_sim_time" value="true" />
  <!-- start world -->
  <node name="gazebo" pkg="gazebo_ros" type="gazebo"
   args="$(find tiago_gazebo)/worlds/small_office.world" respawn="false" output="screen" />
      <!-- include our robots -->
      <include file="$(find multiple_turtlebots_sim)/launch/robots.launch"/>
</launch>

The line that says find tiago_gazebo)/worlds/small_office.world is the one that indicates the world to be launched. This line indicates the world to launch is in package tiago_gazebo and it is called small_office.world.
Since this package is not available anymore in our system, you need to change that world by one that you want to launch. Search on internet for one and the upload it to the rosject. then modify the launch file to point to the path of that world uploaded.

Resolved. Ok based on that, replaced with
GitHub - aws-robotics/aws-robomaker-small-warehouse-world: This Gazebo world is well suited for organizations who are building and testing robot applications for warehouse and logistics use cases..
Thanks

Got same error and resolved as discussed. But following the class afterwards too, after executing -

roslaunch multiple_turtlebots_nav navigation.launch

I got the following error:

The error message indicates that you should install the turtlebot-navigation package.

For that:

sudo apt install ros-kinetic-turtlebot-navigation
