I am lost :) Here is the problem (ROS2). … declare_params_file_cmd = DeclareLaunchArgument( 'params_file', default_value=def_nav2_params_path if robots[0]['name']=='' else def_nav2_params_path_multi, description='Full path to the ROS2 …

I have figured it all out. A fully functional example at https://robotics.snowcron.com, in the "multiple robots" section.

I use ROS 2, Python, Gazebo project. So far, I had the following code snippet to close everything (like RViz) when Gazebo was closed: gazebo_exit_event_handler = RegisterEventHandler( event_handler= …

Figured out. It works like that: ExecuteProcess( cmd=['gzclient'], #cwd=[def_worlds_dir], on_exit=EmitEvent(event=Shutdown(reason='gazebo client exited')), output='screen') Full pr …

I use ROS2/Python/Gazebo Classic project with Galactic. I am looking for a way to dynamically change textures of objects. Any ideas how to do it? …

I found some strange Gazebo behavior that might contribute to my inability to perform fusion. If my robot is programmed to run in a circle, and according to independent (from Gazebo) test, it IS a cir …

I use ROS2/Python/Gazebo project. In online examples, I see robot_localization node using (usually in nav2_params.yaml) the "imu/data" as imu source. …

I have ROS2/Python/Gazebo project, and I use robot localization like this: robot_localization_node = Node( package='robot_localization', executable='ekf_node', name='ekf_filter_node … cmd=['gazebo', '--verbose', world, '-s', 'libgazebo_ros_factory.so', '-r' '-sim-time'], output='screen') arrNodes.append(gazebo_node) # ros2_node = ExecuteProcess( # cmd=['ros2 …

Funny error. In lidar, base frame was set to base_footprint, instead of base_link. No idea why it blocks publishing /clock, but... The working project can be downloaded at robotics.snowcron.com

gazebo_node = ExecuteProcess( cmd=['gazebo', '--verbose', world, '-s', 'libgazebo_ros_factory.so', '-r' '-sim-time'], output='screen') # ros2_node = ExecuteProcess( # cmd=['ros2 …

First of all, it looks like the answer is "you can not". You have to start Gazebo client and server separately. The working project can be downloaded at robotics.snowcron.com

Take a look at my example of docking to aruco at robotics.snowcron.com Important note to people who are going to block this post based on "you have to provide answer here": we are talking about 16 pag …

I am trying to add a vacuum gripper to my ROS2/Gazebo/Python project. I have the following: grip.xacro (note the plugin for gripper): <?xml version="1.0"? … However, when I run $ ros2 service list I do not see any new services showing after I add the plugin, accordingly, it all stops at infinite Service not available, waiting... …

Quite intimidating, really. The plugin has to be inside the <gazebo> tag...

After 3 weeks of research :) I have created a workaround. A fully working gripper example here P.S. It is a long example, with couple of sub-workarounds, so I am not going to post it here.
