I fixed the broken handling of nodelet arguments [https://github.com/cmu-rss-lab/rosdiscover/pull/241]. We get a bit further, but we now see a different error. It looks like the nodelet manager also isn't being constructed correctly.

ChrisTimperley · 2021-11-07T15:31:22Z

Digging a little deeper into the construction of the nodelet manager:

2021-11-07 10:28:12.084 | DEBUG    | rosdiscover.interpreter.interpreter:launch:106 - launching node: camera_nodelet_manager from /opt/ros/indigo/share/rgbd_launch/launch/includes/mana

ChrisTimperley · 2021-11-07T16:26:11Z

And here's the launch file that brings up that nodelet manager. This seems to break a few of our assumptions, @schmerl.
https://github.com/ros-drivers/rgbd_launch/blob/indigo-devel/launch/includes/manager.launch.xml#L18-L22

  <!-- Nodelet manager -->
  <node pkg="nodelet" type="nodelet" name="$(arg name)" args="manager"
        output="screen" launch-prefix="$(arg launch_prefix)">
     <param name="num_worker_threads" value="$(arg num_worker_threads)" />
  </node>

After using the latest fixes, I now get this issue:

KeyError: 'depthimage_to_laserscan'

This tells us that ROSWire isn't seeing the depthimage_to_laserscan package. This is (most likely) because either: (a) the package path isn't set correctly, or (b) node isn't in the image.

ChrisTimperley · 2021-11-08T18:07:56Z

It looks like depthimage_to_laserscan isn't included in the Docker image:

root@e1e6ca5cbd2b:/# find . -name depthimage_to_laserscan
