I am new to ROS and I am trying to get it working on Cozmo. I was following this repository, but I do not understand what I did wrong. When I run this command on the terminal:

roslaunch cozmo_driver demo.launch

I get this error on the terminal windows:

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

Are the files that I downloaded supposed to be in a specific location. I made a folder on my root directory named cozmo_driver. I notice that inside the cozmo_driver there is a folder named launch that has demo.launch. I am also unsure if I have to be in a certain directory to run roslaunch. Any help is greatly appreciated! Thank you

I am new to ROS [..]

How new exactly? Have you completed the introductory tutorials? They may help you get a bit more of an understanding of the different parts that make up a Catkin workspace, how to build packages and how to launch them.
