Question for a starter

1. If you're totally new to programming, I'd suggest a basic programming structure book. There are plenty of famous ones, but the best one I've found for solid basics is not famous, but rather an old text book called Programming Logic & Design by Tony Gaddis -- current versions are over a hundred bucks, but an older 2nd edition is only $5 on eBay (search for "gaddis logic 2nd"). It covers the basics of variables, conditional logic, loops, etc. and lays a great foundation before reading or writing code in any language.

2. I agree with @lemster68 about just reading the RAPID manuals -- RAPID is a very manageable language and the RAPID Instructions, Functions and Data types manual is included with the RobotStudio install, can easily be called when reviewing code in RobotStudio by pressing [F1], and can also be found online too (instructions, functions, data types). I'd recommend daily reviewing a few instructions, functions, or data types online -- not to memorize exact syntax, but rather to just continuously remind yourself what's tools are available in RAPID.

3. Get as much from being around actual robots (with production-quality code) as you can: Study the FlexPendant manual (included with RobotStudio install) and go play with the ones you have. If you have time, watch the Production Window on the pendent while your robots run and watch the program pointer move as the robot does. Look at all the sections under the [ABB] button, etc. Lookup any terms you don't know and learn.

4. After at least a few months/years of getting up to speed with programming structure, the RAPID language, and playing with them live, then consider going to a Programming 1 class at ABB, then 2 and 3 if you can get it.

5. Not sure if you're looking to get into the offline programming of RobotStudio (programming using virtual 3D CAD of a part), but if so, watch all the videos you can find on RobotStudio. Try to do what they do, etc. A couple months/years in, go to RobotStudio 1 class.
