Hi there, I am using the gazebo spawn client to spawn a Husky A200 (via launch file) and a Robotnik AGV (via spawn client in source code) into the same Gazebo world and I can see both robots in Gazebo but in RViZ when I add a robot model I only see the Husky. How can I add the AGV also to Rviz so that I have 2 robots in the same scene ? My source code is here Please advise.
