Aruco models not there for two markers

[rahulmdh]

While launching the simulator.launch file, two of the four aruco markers don't appear in the Gazebo world since there model files are not there in ~/.gazebo/models. I checked in the repo but there only two model folders maker0 and marker1. I don't understand how it got loaded in the video tutorials. Please help with this. Thanks

when you launch the gazebo. From the existing model you can add the number of marker model and save the complete world with new name. Launch the simulator.launch with new world file.
