# Revision history [back]

I believe you forgot to specify model name in your include tags, so joints can't find their parents or children and don't glue them together

what you're doing :

 <include>
<uri>model://lidar</uri>
<pose>-0.12 0 0 0 3.1415 0</pose>
</include>


what to try:

 <include>
<uri>model://lidar</uri>
<pose>-0.12 0 0 0 3.1415 0</pose>
<name> lidar </name>
</include>


etc.
