3135: Clarification on regarding temporary restriction of Toggle movement using a C-Channel

Rule Quote: <GG9>

Robots may not intentionally grasp, grapple, hook, attach to or otherwise Entangled with any Field Elements. Strategies with mechanisms that react against multiple sides of a Field Element in an effort to latch or hook onto said Field Element are prohibited. The intent of this rule is to prevent Teams from unintentionally damaging the Field and/or from anchoring to or otherwise Entangling themselves with the Field. Whenever possible, Head Referees should alert Teams to potential Violations before they happen to prevent actual Violations. If a Robot takes immediate action to avoid or resolve the issue, and if the Head Referee determines that the issue had no effect on the Match, no Violation should be recorded.

<SC4>

SC4> A Toggle is considered set to a color when it meets all of the following criteria at the end of the Match: a. The Toggle must be fully seated, such that there is a face of the Toggle in contact and parallel with its mounts on the Field Perimeter at rest. (see Figure SC5-1) b. The Toggle is not in contact with a Robot from either Alliance.

Question: In the context of the current game, is it legal for a robot to position a piece of C-channel underneath the Toggle mechanism to prevent it from rotating?

The mechanism is not "clamped" or "grasped" in a way that prevents the robot from driving away (no permanent attachment), but the geometry of the C-channel effectively wedges the Toggle so it cannot be turned by an opponent. Does this "jamming" action constitute "attaching to a field element", or is it considered a legal defensive strategy provided the robot can move away freely?

A Robot mechanism interacting with the Toggle as described is not inherently a GG9 violation.

Provided the Robot does not violate R18 and/or S1, this may be considered a legal gameplay interaction.

The Game Design Committee will continue to monitor Robot interactions with Toggles throughout the season, and this ruling may be subject to change if needed, based on observed gameplay.
