Regarding surface water vehicle simulation in ROS Gazebo

[SaailN]

I had gone through your github repo of uuv_simulator as i am working on a similar kind of project.
I am working on a simulation of unmanned surface water vehicle using ROS Gazebo. I tried to use hydrodynamics(buoyancy) plugin and aerodynamics(drag) plugin for water physics. But the hydrodynamics plugin is applied to entire world of gazebo due to which my robot goes up till infinity due to buoyant force. Also i am not able to get proper drag forces of water.
How to use your buoyancy plugin for my project.
It would be helpful if you can tell ,how to create a water world for surface water vehicle so that i can get the exact drag and buoyant forces acted on my robot so that it can actuate properly?

Hi, this is similar to #388. I'll repeat what I said there as well.

I would recommend the VRX Simulator for USV simulation. It is stable and has support for many sensors including GPS, IMU, 3D lidar, cameras and has good documentation as well.
