Spot_ws problems

[liver121888]

Hi, I am following ur tutorials. I encountered problems with launching the command

roslaunch spot_config gazebo.launch

I got:

RLException: [gazebo.launch] is neither a launch file in package [spot_config] nor is [spot_config] a launch file name
The traceback for the exception was written to the log file

I already source the setup.bash, it confused me since rospack list could not find the spot_config pkg.

so I tried to add the champ's robots repo and install spot_ros there using ./install_descriptions.

and launch the same command, it works but I am getting

[WARN] [WallTime: 1438070984.731293] [4.961000] Controller Spawner couldn't find the expected controller_manager ROS interface.

I look up solutions online but find nothing useful. I am the one who opens the pull request and tries to fix the submodule problem so I can replicate your work. Please help! I really thinks your tutorials are great!
