Adjusting an open source package

I am trying to run a center lane detection as well as a line follow package, however, the nodes which are being launched for moving the robot are the rosserial (Arduino serial) but I want it to publish directly to the cmd_vel.

Should I remove the launching of this file and adjust the topics inside the script?

I am using this project btw:

Any recommendation in general how to adjust the files? what do I need to look at to customize it to my use?

Any recommendation/advice is appreciated

Hmm the guy seems to be publishing directly to cmd_vel in that project, there’s even a screenshot:

Perhaps you’re looking at the wrong script. Anyhow you should probably find where the velocity is being sent to the arduino, print out the values and if they’re correct just publish it to cmd_vel instead.
