Cannot launch node

I am doing the second quiz of TF ROS 101. I got stuck in two places:

First: When I launch my file It shows an error as ERROR: cannot launch node of type [tf_quiz_static_transform/static _transform_publisher]: can’t locate node

    <launch>
    <node name= "world_frames_connection" pkg="tf_quiz_static_transform" type="static_transform_publisher">
          args="0 0 0 0 0 0 robot2_tf/odom robot2_tf/odom 10">
    </node>
</launch>

This is my launch file

Second: When I submit my launch file it show this

So, What am I missing here?

Hi,

Have you checked that the

static_transform_publisher

File is executable and has that name? Isnt it a python script an dthere should be static_transform_publisher.py ?

I found the solution the package is the tf of the state_node_publisher

<launch>

    <node pkg="tf" type="static_transform_publisher" name="world_frames_connection" 

          args="0 0 0 0 0 0 robot2_tf/odom robot1_tf/odom 20">

    </node>

  <node pkg="rviz" 

        type="rviz" 

        name="rviz"/>

</launch>
