I am building a robot that is within the legal starting size. When it drives forward, flex wheels launch forward for our intake, and on the other side, we have a grabber that can move out using a motor to grab mobile goals. Is the grabber considered an expansion?
Depends. If the grabber, combined with the length for the flex wheels fall out of 18 inches, it is considered expansion. If it is contained within the 18 inch cube, it is not expansion
If it expands beyond your drive base/robot length. If it just expands but is still contained in the original starting size it is fine. But if it sticks outwards then yes it counts.

Alright. Thanks for the information.
For this to be legal, one of them must start at their absolute limit. Even if it is within the size limit, you may not expand from two or more sides.
