roslaunch underwater_vehicle_dynamics UWSim_g500_dynamics.launch

[CodeWanglufei]

I have a problem. When I try the controller with Simulink, firstly I comment the keyboard controller in the /UWSim_g500_dynamics.launch file, then I use ' roslaunch underwater_vehicle_dynamics UWSim_g500_dynamics.launch ' in my terminal.
The problem shows below.

Starting UWSim...

How to solve ? Looking forward to your reply.
