unable to set control
When I run the package, I got these errors. what's wrong? I just installed the package and ran it. Do I have to do something else? Thank you
Environment : Ubuntu 12.04 LTS, ROS hydro
Please format your answer. Try running from a launch file with the options as presented above. This normally happens when a certain setting is not available or if it cannot be achieved. For example, if a camera cannot give you 30 fps at 640x480 resolution, it will fail as above.
