Thanks solved my problem. Normal class destructor __del__() is called but it seems that rospy is already shutdown by tha

Pressing Reset in RViz bottom left corner (and probably republishing marker) seems to the job You can test it by renami

Inside which tag <ambient> should be put?

For some reason c_str() didn't work for me so I used data() instead: ROS_INFO("frame: %s", msg.header.frame_id.data());

I modified MumboJumbo code to give human readable output: To run: python rosbag_size_by_topic.py BAG_FILE_PATH or ro

This will list all packages found between <exec_depend>, <build_depend>, <run_depend>, <depend>

I'm coming from ROS1 background and I'm new with ROS2. I want to launch rviz with config file in ROS2 by specifying relative path from package package_name

ROS1 equivalent would be:

<launch>
  <node type="rviz" name="rviz" pkg="rviz" args="-d $(find package_name)/config/config_file.rviz" />
</launch>

What I have in ROS2 is:

from launch import LaunchDescription
from ament_index_python.packages import get_package_share_directory
from launch_ros.actions import Node
import os.path

def generate_launch_description():
    return LaunchDescription([
        Node(
            package='rviz2',
            namespace='',
            executable='rviz2',
            name='rviz2',
            arguments=['-d' + os.path.join(get_package_share_directory('package_name'), 'config', 'config_file.rviz')]
        )
    ])

But this approach has 2 problems:

1. get_package_share_directory returns path to ...install/package_name/share... but I want .../src/package_name/config/config_file.rviz (just like in ROS1 what $(find package_name) would return) because there's no config_file.rviz in install directory. Even if it was
2. I want to save new rviz settings to src directory not to install because install is not tracked by git

I searched documentation, answers.ros.org and github but couldn't find the answer. So what is equivalent of $(find package_name) in ROS2? Or maybe all files should be installed in shared directory if so how to deal with problem 2.

@gvdhoorn Oh right. Made new one-liner to address that that return apt packages. Could you check it and see does it have

Looks like the prefix variable comes from catkin: https://github.com/ros/catkin/commit/6b30f78a230a5d3de79f19dbf230ff45

It helped to find a fix. I'm using Win10 WSL2 Docker to run rviz, for XServer I use MobaXTerm terminal. In MobaXTerm go

Had problem that no headers were found. Adding include_directories(include ${catkin_INCLUDE_DIRS}) fixed it thanks

One way would be to to write a node which converts cmd_vel to /vesc/commands/motor/speed for each wheel. You can also pu

Also remember to import import tf import geometry_msgs And for someone who doesn't know star "*" here *tf_conversions

For relative path use this just change MY_PACKAGE to your package name. Tested on Noetic: <launch> <arg nam

Check out this "ROS Navigation Tuning Guide" it was quite useful: https://arxiv.org/pdf/1706.09068.pdf

Yes you can: # MyAction.action # Goal constants uint8 AAAAAAAAAAAAAAAAAAAAAAAAAA = 42 --- # Result constants uint8 BBBB

It's not direct answer to your question but maybe someone could find it useful. First make sure if you are using sim_tim

Ended up with this launch file to run Mapviz and to have transform to /wgs84 <launch> <!--WGS84 transform

Could it be because misspelled $(find robo_description)

Shouldn't you use something like this to convert from pixel to world in meters (not sure if it has to be + or - origin_x
