What elements must be touched for tower points to count?

For tower points to count in the context of the FRC Rebuilt game rules, it is essential for the robot to make contact with at least one rung and/or upright of the tower. This requirement ensures that the robot is actively engaging with the scoring mechanism of the tower, which is designed to reward teams for climbing and elevating their position during the match. By touching either a rung or an upright, the robot demonstrates its participation in the tower scoring process, which is integral to strategy and outcome in competitive play.

Other choices do not meet the criteria set forth by the game rules. Focusing only on the tower itself does not encompass the necessary actions involving the rungs or uprights. Touching just the ground or any arbitrary part of the robot would not fulfill the specific interactions required for scoring tower points, as these actions do not establish the required connection with the scoring elements of the game.
