It seems like, velocity_controllers package is not installed.
To fix this, just install with apt.
$ sudo apt install ros-kinetic-velocity-controllersBut, this error should be avoided with rosdep command.
If you did not do following command, you need it.
$ cd <catkin_ws>
$ rosdep install -i -y -r --from-paths srcAfter above rosdep command, if you still have an execution error, that means we mistake a dependency.
That should be fixed.
Everything seems to be built successfully. When I ran the command "roslaunch ros_ship_gazebo_plugins wam-v_gazebo.launch", the ship could not be controlled. The errors can be found in the terminal like the following, can you give me some helpful suggestion? Thanks very much!
