Issues with launching gazebo

[destkk]

Operating system: Ubuntu 20.04

Hi there. I have built a 2 level map using traffic editor (see screenshot below) using a floor plan and robot's map as a layer. After which I have compiled the workspace and the launch file but I am receiving the following errors below,

For what I have observed is that the fleet adapter and rmf_dispatcher node is launched without any issue. I supposed is only the gazebo has issues.

Could anyone advice me the possible methods to troubleshoot?

Hi there,

There are a few things going on:

1. RVIZ errors: The rviz2_plugin package was renamed to rmf_visualization_rviz2_plugins and hence you will need to update these references in your .rviz file. Also delete the reference to RMF Panel in the same config as the package has been dropped. You may refer to clinic.rviz

2. Regarding the Key[name] errors, this may arise if you didn't assign a name for the door and lift in rmf_traffic_editor. So please ensure that you have populated these fields. Do a clean build of your maps package and try launching the world after.

3. Looks like you have not set the scale for any of the levels using the Measurement tool. To generate realistic environments, make sure you define a measurement between any two points on your map. For more info, see https://osrf.github.io/ros2multirobotbook/traffic-editor.html
