Sample codes on camera feedback/laser range/speed? [closed]
Hey guys, I am working on a thesis where I have to build an interface between ROS and a state-of-the-art system they have at the uni. Since I feel my knowledge on ROS is pretty lacking after doing the tutorials and reading parts of the site and answers section. That's why I wonder if there are sample codes for receiving camera feedback, laser range or speed control. Or a simple publisher/subscriber for that matter. What I am interested in is understanding its process and the type of parameters sent in each interaction.
Any sort of help would be appreciated (even if it means 'read this article or this document'.
Thanks :3!
