Unofficial Answer: Stacked cones (SG9)

[B-Kinney]

Original question:

@6793A Recently an update to SG9 was posted that talked about stacked cone possession being legal as only one cone. The example talks about cones being stacked on a mobile base. However it does not specifically state that stacked cones can only be stacked on a mobile base to meet the possession rule. Does it also mean that if more than one cone is stacked on each other and not on a base it would still be legal to have in possession.

Hi, @6793A.

According to the definition of Stacked:

A Cone is Stacked on a Goal if it is not touching a Robot of the same color Alliance as the Goal and either:
a) Fully nested on a Goal (see Figures 5 & 6).
b) Fully nested on a Stacked Cone (see Figures 7 & 8).

This means that in order for a cone to be Stacked, either that cone or one of the cones underneath it must be fully nested on a mobile goal.

It was clarified in this thread that if a cone is fully nested on a mobile goal or Stacked cone, that cone doesn’t count towards the Possession limit, even if the robot is touching it. (The robot would be allowed to touch an unlimited number of cones on this stack, even if it is also touching one un-Stacked cone.) However, the cone still needs to be fully nested.

To answer your question:
If more than one cone is stacked on each other but not on a base, it is not legal for a robot to possess it. (The robot could touch the top cone, but no other cones.)

No. You cannot Possess two cones without at least one of them being Nested on a mobile goal. If you have a cone (sans goal), and place another cone on top of it, you are violating <SG9>.
