<SG3>

Vertical expansion is limited. Once the Match begins, Robots may expand vertically, but may never contact and/or break more than two Planes of the Ladder at any given time.
  • For a Robot that is on the Floor (i.e., not Climbing), this is effectively a height limit of 32”, the distance between the Floor and the top of the gray rung of the Ladder.
  • This vertical limit is measured from the perspective of the Field; i.e., it does not “rotate with the Robot.”
  • Levels and Planes coincide with the horizontal and vertical dimensions of the Ladder rungs, but expand infinitely and are not limited to the volume of the Ladder. Each Level corresponds to a vertical section of the Ladder.
  • Level 0: 0”, the Floor tiles
  • Level 1: less than 18.16”, from the Floor to the top of the black rung
  • Level 2: 18.17”-32.16”, from the top of the black rung to the top of the gray rung
  • Level 3: 32.17: to 46.16 inches, from the top of the gray rung to the top of the yellow rung
  • Level 4: ≥46.17 inches, above the yellow rung
  • Each Plane marks the dividing line between two Levels.
  • Plane 0: Floor tiles
  • Plane 1-2: top edge of the black rung of the Ladder
  • Plane 2-3: top edge of the gray rung of the Ladder
  • Plane 3-4: top edge of the yellow rung of the Ladder

    Violation Notes: If a Robot falls or “droops” after the Match ends and leads to an <SG3> Violation, this will likely be considered a Minor Violation, provided no other rules are Violated. Their Climb will be scored where they come to rest; see <SC1>.
