I followed this https://answers.ros.org/question/41433/multiple-robots-simulation-and-navigation/ to make two huskies in navigation stack. When i launch navigation file and rviz I can set the map and both robots. TFs are all fine and I type correct tfprefix to see robots, but they are always in the centre of the map and not in their correct position and models are not looking correctly because wheels are not showing. I tried using 2D pose and 2D nav goal and i changed topic for those actions. Using rostopic echo /husky1/movebase_simple/goal it shows change but robot is not moving. Both robots stay in the same place in gazebo and in rviz there's still only one robot in map.
