I have a quick question regarding the rule SC7. It says the robot is considered to climb to a level if it meets certain criteria.
One of the criteria states that robot must not contact any other field elements (including foam tiles)
So my question is that would it still count as climbing if our robot is holding a mobile goal? And if it does still count, would we also get the mobile goal points as well as climbing?
It will not count.
And if you try to drop the mobile goal, you might damage it
<R6> says that mechanisms that could damage Field Elements or Scoring Objects are not allowed (which could be extended to mean “don’t break stuff”)
Check the version 3.0 changelog at the beginning of the manual, specifically the point about deleting SC7 clause C and what that means 
Also, if you look up the definition of field elements, you won’t find scoring objects mentioned. Those are not field elements.
By field elements the mean the physical parts of the field that are attached like if you some how climbed and were touching a wall or wall stake
