It was within the frame perimeter and then outside the frame perimeter, as it rotated, attempting to pickup balls. Because of that he said we'd be hit with a rules violation. We were forced to redesign our unit, so as not to extend beyond the frame.

[G21]
Robots may extend one appendage up to 14 in. beyond a single edge of their frame perimeter at any time.
Violation: Foul for exceeding size allotments; Technical-Foul for continuous or repeated violations.

These appendages are intended for use in manipulating Basketballs and/or Bridges. A Robot may have multiple extension devices onboard, but only one may be deployed at a given time.

All portions of an appendage that are outside the Frame Perimeter must be contiguous with each other. Very brief violations of the contiguity requirement as a single appendage is being extended or retracted will not be penalized.[/blue box]

That looks legal to me. I'd like to see a picture of yours, but I have a feeling that you may not have needed to modify it. Clearly on FRC1538's bot, everything comes down at once. As the assembly itself is contiguous, it should be ok.

Was he saying the belts weren't contiguous because they were partly in the frame and partly out of it? Or was he concerned that the belts were the leading edge, so as you lowered it, there is a moment where the tips of a few belts are breaking the plane? The brief violation note should get you through here. It's clearly the intent of the rule that transitioning between flipped up and down shouldn't cause a penalty.
