Hi all,

I'm creating a model four wheeled robot model. My SDF file is quite large but I'll attach it at the bottom of this question. As soon as I spawn this SDF into the world it starts flying around in several separated pieces. If anyone can figure what is causing this please let me know.

Please note this world launch file I am using is sound as when I use other SDF Files it does not have this same issue.

Thanks guys!! C:\fakepath\model.sdf
