using and communicating between multiple quadrotors (usign hector_quadrotor) [closed]

edit

Hi all,

I am doing a project which simulates multiple UAVs going around a specified area (the project I am working on is a flooded area for search and rescue) sending an image stream back to the user. I am currently familiarizing myself with using the hector_quadrotor package (which is quite a challenge given that I have never used neither ros nor gazebo before). Now I am trying to find out how to spawn multiple UAVs (ideally from the same terminal) and how to communicate between the robots for collision avoidance whilst going around the entire area. Could someone kindly give me a few pointers on how this can be achieved efficiently using ROS?

Thanks a lot in advance,

JP
