Cannot launch package

tellez, thanks for the response. My apology for the “very” late response. I use Chrome as a browser. However, I now have a new problem see screen shot below:

There is an error I now need to clear.

The problem in your image is that you are trying to launch a launch file named move and that doesn’t exist.

You have a problem there: move is not a proper name for a launch file. Launch files should end with .launch. So the error indicates that a launch file named move doesn’t exist, which makes perfect sense.

Please check two things:

  1. Your roslaunch command should be calling a proper launch file
  2. Check that the launch file you are calling does exist in the package you are mentioning (publisher_example)
