Answered: Clarification on trapping and tipping

The definition of trapping states that “a robot is considered to be trapped if an opposing robot has restricted it into a small, confined area of the field, approximately the size of one field foam tile or less, and has not provided an avenue for escape.”

Is the “small confined area” considered to be a flat 2x2 foot plane, or a 3 dimensional 2x2x2 cube? If a robot stops their opponent from expanding vertically more than the height of a field tile on its end, is this considered to be trapping? Does the answer change if the robot cannot escape to an area where it can expand vertically?

Say that robot A drives to the goal holding three bucky balls. Robot B sees that robot A is about to score in the goal and raises their lift to half height and positions their robot so that the lift is above, but not touching, the opponent’s robot.

  1. would robot A be penalized for expanding vertically in an attempt to score, knowing that their actions could tip the opponent?

  2. would robot B be penalized for restricting the opponent’s vertical movement to less than the height of a field tile?

I understand that you cannot give blanket rulings based on specific situations, but any clarification would be helpful.

Thank you, Karthik!

This rule deals with teams being restricted to an area of approximately 2’ x 2’, not a volume of 2’ x 2’ x 2’.
