Unable to move robot inside gazebo.

edit

Hi Guys,

I am trying to move my robot inside gazebo. It spawns correctly inside the gazebo but unable to move. Here is the git link for both the description and gazebo packages .

Both controllers are loaded into controller manager correctly. Mobile base controller is simple differential drive controller.

Terminal output

[ERROR] [1561465362.421175467, 0.358000000]: GazeboRosControlPlugin missing <legacyModeNS> while using DefaultRobotHWSim, defaults to true.
This setting assumes you have an old package with an old implementation of DefaultRobotHWSim, where the robotNamespace is disregarded and absolute paths are used instead.
If you do not want to fix this issue in an old package just set <legacyModeNS> to true.
