The above file is my file.urdf. I want to simulate my robot (load the urdf file to gazebo), but i got some errors :

  1. [ERROR] [1608996333.891904672, 187.321000000]: Updating ModelState: for model[MyrobotName], specified reference frame entity [world_ned] does not exist
  2. My model in gazebo was behaving weird / unexpected, then I add <static>true</static>. It solved it, but when I simulated it, my model in Gazebo did not move even though my model in rvis can move.

Could anyone tell me what causes it ? and does anyone know how to sole it ?
