Curved Bumpers, Expansion during finale

[2010FRC3167]

1.) Is the fixed polygon of the robot required to be a polygon, or can it have a curved surface?
2.) In the finale, (final 20sec), since the robot size expands, is it allowed to use these expansions to continue to shoot balls at the goal?

1) It is requred to be a polygon. A Polygon has straight facets. Per Rule <R07-B>, each must be of at least 6 inches in length.
2) There are no rules that prohibit scoring BALLS while in the FINALE CONFIGURATION. However, expansion to the FINALE CONFIGURATION may not alter the FRAME PERIMETER, as constrained in Rule <R11>. Also note that a ROBOT may only interact with BALLS per <G30-A> and that <G43>, <G45> and <G46> all still apply during the FINALE.

UPDATE : Specific to part 1, we stated previously in this thread that there are no rules that prohibit curved BUMPERS, and retract the answer provided above (on January 21). Please note that while curved BUMPERS are not explicitly prohibited, please refer to Rule <R07-B> and understand that curved BUMPERS must be at least as strong/robust as straight BUMPERS.

We apologize for the conflicting answers and request your patience as we strive for consistency. In response to this, we have opted for the less restrictive rule as not to punish those who have been working to the less restrictive initial answer.
