ROS 2 update

Hi.

First of all, big thanks to the authors and maintainers of this project – great work!

I have a question: Do you have any plans to add ROS 2 support to MARSIM? I'm really interested in using MARSIM for my research and would love cite some of your awesome work. However, I need to integrate it with ROS2.

It would be fantastic if you're considering making it ROS 2 compatible. I guess there are at least hundreds of researchers hoping this to be converted to ROS 2! Or, could you offer any advice on how to port it to ROS 2? For example, which part of the repo should be largely ported from ROS to ROS 2. I'd greatly appreciate it.

By the way, I'm curious if there's any connection between the uav_simulator in FUEL's repository and MARSIM. Are these simulators completely independent?

Thanks for your appreciation! Adding ROS2 support to MARSIM would be a great idea and I also expect MARSIM can be used by many ROS2 users, but now I don't have time to complete this function, which is a pity.
However, I can give you help as much as possible if you want to do it and contribute to the repository. For my opinion, the most important part is the local_sensing module. As far as I know, you may only change the subscriber and publisher, and you can obtain the ROS 2 version?
And for the uav_simulator problem, the one in MARSIM is totally independent with the one in FUEL (maybe only having some same interface). I write the controller and dynamic kinematic simulation of UAV by myself.
Hope it helps! If you have any problem, dont hesitate to contact me
