Hello everybody,

I am new to ROS and I was wondering what are the common problems when implementing ROS? What should I pay attention to etc.

Thank you.

You cannot get an answer for such a question. Everybody is different, different know-now, experience, background and knwoledge. At best you give it a try and then can you say which problems you encountered. That's all

As a beginner, there are three things you really need to understand (IMHO):

  1. ROS nodes as independent computational units
  2. Messages and how they provide an interface between/among nodes
  3. The callback queue(s) and how to use spin/spinOnce for internal node operation

With those in hand, you'll be well prepared to build fairly complex systems.
