2021-08-21 01:23:06 -0500 marked best answer How to load parameter file for global_costmap node started by nav2_planner?

Hi!

I want to use only the path planning feature in ROS2 Navigation2. My problem is, that when I'm launching the nav2_planner, it starts the global_costmap node automatically. I have a parameter file, which contains only parameters for the global costmap.

How do I provide the parameter file successfully for the global_costmap to load it? (by not launching myself another instance of global_costmap?) Below is the launch file I'm using.

import launch
from launch.substitutions import Command, LaunchConfiguration
import launch_ros
import os

def generate_launch_description():

    lifecycle_nodes = ['map_server',
                       'amcl',
                       'planner_server']

    return launch.LaunchDescription([

        launch_ros.actions.Node(
            package='nav2_map_server',
            executable='map_server',
            name='map_server',
            output='screen',
            parameters=[{'yaml_filename':'~/map.yaml'}]),

        launch_ros.actions.Node(
            package='nav2_amcl',
            executable='amcl',
            name='amcl',
            output='screen'),
            #parameters=[{''}]),

        launch_ros.actions.Node(
            package='nav2_planner',
            executable='planner_server',
            name='planner_server',
            output='screen'),
            #parameters=[{'params_file':'~/path_planner_params.yaml'}]),

        launch_ros.actions.Node(
            package='nav2_lifecycle_manager',
            executable='lifecycle_manager',
            name='lifecycle_manager_planning',
            output='screen',
            parameters=[{'use_sim_time':False},
                {'autostart': True},
                {'node_names': lifecycle_nodes},

    ])

In my case I noticed, that the map is published only once in the beginning by the map_server node after node's startup.

2021-05-31 05:55:43 -0500 marked best answer Unable to locate package realsense2_camera for Foxy

Hi!

I'm wondering, why I'm not able to find/install realsense2_camera package for ROS2 Foxy. The package is not found by the command

sudo apt-get install ros-foxy-realsense2-camera

E: Unable to locate package ros-foxy-realsense2-camera

However, realsense2_camera_msgs and realsense2_descriptions are found, but according to ROS Index, the realsense2_camera should be also found.
