title: No transformation found in rviz
body: <p>I'm trying to setup simulated pepper in gazebo for navigation but I can't visualize any topic in map or odom frame because rviz can't find any transformation between links but my tf tree looks normal. <a href="https://i.stack.imgur.com/naU5J.jpg" rel="nofollow noreferrer">my rviz errors</a> <a href="https://i.stack.imgur.com/5uYjZ.jpg" rel="nofollow noreferrer">my tf tree</a>. I think the problem might be with the names of the frames because in tf tree they all have prefix pepper_robot and in rviz they are missing that prefix.
  Thanks</p>
