supported file format for rviz2 besides .dae? Hello, I am able to successfully render a model .dae file in rviz2 with m

A binary .stl should certainly work. I do not believe RViz supports obj (unless that's changed somewhat recently).

Im using the below python launch file:

#!/usr/bin/env python3

from rclpy.node import Node

from std_msgs.msg import String

from launch_ros.substitutions import FindPackageShare

def generate_launch_description():
    # Load the URDF into a parameter
    bringup_dir = get_package_share_directory('urdfpublisher')
    urdf_path = os.path.join(bringup_dir, 'urdf', 'doggo.urdf')
    urdf = open(urdf_path).read()

    return launch.LaunchDescription([
        launch_ros.actions.Node(

            package='robot_state_publisher',
            executable='robot_state_publisher',
            parameters=[{'robot_description': urdf}],
        ),
        launch_ros.actions.Node(

            package='joint_state_publisher',
            executable='joint_state_publisher',
            parameters=[{'use_gui': True}],
        )
    ])



def main(argv=sys.argv[1:]):
    """Run lifecycle nodes via launch."""
    ld = generate_launch_description()
    ls = launch.LaunchService(argv=argv)
    ls.include_launch_description(ld)

    #launch robot_description topic
    node = rclpy.create_node('robot_description')
    publisher = node.create_publisher(generate_launch_description, 'robot_description', 10)

    #Fails when generating launch description with joint state publisher here
    publisher.publish(generate_launch_description)

    #publisher = node.create_publisher(String, 'sos')

    return ls.run()



if __name__ == '__main__':
    main()

to try and publish robot_description and joint_state_publisher with GUI enabled but I get the error "[joint_state_publisher]: Waiting for robot_description to be published on the robot_description topic..." thrown. When i remove joint_state_publisher, RVIZ2 is able to correctly pick up on robot_description meaning it should be getting published. The terminal logs also look nearly identical when joint_state_publisher is removed.

Launch file log with joint_state_publisher removed from "return launch.LaunchDescription" block:

Not sure why joint_state_publisher is being finicky and the joint_state_publisher GitHub page doesn't have any .py launch file examples.

Yep, this fixes it. I wish error handling for this was more specific like "error: expected type x, got type y" or someth

I want to publish 3 ints as a message but i'm getting this vague error that I'm not sure how to solve this.

This is the relevant bit of my code:

self.publisher = self.create_publisher(
    Int32,
    'wheel_settings',
    10)
#test publishing wheel settings
self.publisher.publish([1, 1, 1])

Error: "raise TypeError()"

How do I fix this? P
