Course Project Step 2 Fixed Frame [map] does not exist

Dear all,

I am doing step 2 of the course project.

In the launch file, I launch the map_server node.

<arg name="map_file" default="$(find my_summit_mapping)/maps/my_map.yaml" >
<node name="map_server" pkg="map_server" type="map_server" args="$(arg map_file)" >

However, in RVIZ, it shows “Fixed Frame [map] does not exist”

The /tf for from map was not published as I knew from view_frame.
But I thought /map_server publishes /tf from map to other sources.

Do I miss some things?

Thanks a lot!

Best regards,

I know the reason.

I forgot to change these frame ids:

<param name="odom_frame_id" value="summit_xl_a_odom"/>
<param name="base_frame_id" value="summit_xl_a_base_footprint"/>


I’m glad you were able to solve the issue by yourself.
