Hi, I am doing a simulation project and which BlueROV2 Heavy as the simulated vehicle using Gazebo. Currently, I am stuck with the control of the vehicle. In orca4, I could use the simulator to do an automated mission (mission_runner.py), but when I replace the original model with BlueROV2 Heavy, the vehicle behaves weirdly. I believe I should configure the vehicle but I am uncertain which files I should modify. Thanks
