2152: Definition of controlling in the context of <RSC8> and <G10>

Kevin Li (Event Partner)
24-Sep-2024

<G10> provides a definition of "controlled" for teamwork matches, but <RSC8> is listed as an explicit exception to <G10>. Should the definition for "controlled" from <G10> also apply to <RSC8>?

Secondly, if a robot is partially surrounding a ball, or the ball is in a concave part of the robot but not contacting it, would the ball still be considered being controlled? If the robot's concavity results in the ball being moved when the robot turns as per <G10>, should this still be considered controlling the ball?

Thirdly, if a robot is supporting a ball that is also supported by the goal or goal wall, is this considered controlled by the robot? This could involve three scenarios after the robot is pulled away:

  1. the ball remains partially in the goal due to the switch mechanism squeezing it,
  2. the ball falls down onto the field tiles, out of the goal once the robot is handled (attached image).
  3. the ball falls through the goal wall, would the ball be considered scored or removed?.

Thank you for your questions!

Yes, the definition for "controlled" in rule <G10> applies to rule <RSC8>. The blue box following rule <RSC8> will be revised in the next game manual update to read (bold added here for emphasis), "This rule is an explicit exception to rule <G9> and the Violation Note for <G10>, and may be used as part of a Team’s strategy for Autonomous Coding Skills Matches. Driving Skills Matches are still governed by <G9> & the Violation Note for <G10>, especially for strategic violations." This change is effective immediately.

Yes, as described in clause Bi of rule <G10>, "... if the Ball moves with the Robot either vertically or while turning, then the Robot is “controlling” the Ball."

If a Ball is supported between the Robot and the Goal Wall at the beginning of a robot reset under either <G10> or <RSC8>, if the Ball falls through the Goal Wall or remains 'stuck' in a Target after the Robot is removed, that Ball should not be considered as controlled by the Robot. If the Ball falls into the field or otherwise moves with the Robot, it should be considered as controlled by the Robot. Teams should be very careful in these scenarios to avoid intentionally moving a Ball through a Target during a Robot reset to ensure that it is clear to the Head Referee that the Team is not using the reset as a strategy to score the Ball.
