SG6 limits Possession to a maximum of one (1) Pin and one (1) Cup, and SG6a clarifies that Plowing multiple Scoring Objects is permitted.
Appendix B defines Possession as a status where "a Robot's change in direction would result in controlled movement of the Scoring Object," typically requires at least one of the following:
- the object is fully supported
- moved in a preferred direction inside a concave face...
- held against the Floor or a Field Element.
Plowing is defined as intentionally moving an object in a preferred direction with a flat or convex face or with another Scoring Object (emphasis mine).
Consider a stack consisting of several Pins and Cups. A Robot uses a concave mechanism such as a claw, to grab a single Scoring Object at the bottom of that stack. The bottom cup or pin is contacting the robot and meets the definition of possession, however the remaining pins and cups only meet the first dot point, and is "moving with another Scoring Object."
Is the Robot considered to be Possessing only the single Scoring Object it has directly grasped, with the remaining stacked objects treated as plowed? Or, because the Robot's change in direction results in controlled movement of every object in the stack, is the Robot considered to be Possessing all of those Pins and Cups placing it in Violation of SG6 once the count exceeds one Pin and/or one Cup?
