Vertical expansion is limited. Robots may expand vertically within the following conditions:
  • The Robot must not be contacting the gray field tiles in either Low Goal.
  • No part of the Robot may exceed an overall height of 24”. This height limit is a “virtual ceiling,” meaning that no part of any Robot may ever exceed 24” above the foam tiles, regardless of Robot orientation.
  • Any extensions or combinations of extensions above 18” must fit within a vertical cylinder 2” in diameter.
  • There are no vertical expansion limits during the Endgame.
  • Robots may not contact the High Goal, Discs which are Scored in the High Goal, or the horizontal supporting structures directly underneath the High Goal. This rule applies at all times, regardless of Alliance / High Goal color.

  • Figure 20: Vertical dimensions of the High Goal
    The Rollers are made from 2” nominal Schedule 40 PVC pipe, with an average inner diameter of 2.067” (52mm). A Roller, or any other piece of 2” Schedule 40 PVC pipe, can be used to check Robot compliance with part “c” of this rule. If a vertically extending mechanism touches the inner walls of the PVC pipe, then it is too wide. See Figure 20. The intent of this height limit is to prevent mechanisms from extending above the bottom half of the High Goal, which is roughly 25” from the foam tiles. If a mechanism extends above the top of this Field Element, then it is too tall. A Robot that has not extended vertically should be able to drive under the supporting structure of the High Goal without contacting it.

    Violation Notes:
  • Repeated Minor Violations that involve interference with gameplay, such as blocking an opponent’s launched Disc while contacting a Low Goal, may escalate to a Major Violations at the Head Referee’s discretion.
  • It is expected that momentary Minor Violations may occur, such as a mechanism retracting while a Robot enters a Low Goal, or while driving over a Disc. These will likely only result in a warning, if no gameplay interference occurs.
  • Even if an expansion was accidental, it can still be considered a Major Violation if the Head Referee judges that the expansion was intentional, strategic, and / or Match Affecting. This especially applies to part “e” of this rule.
