Autonomous Line – The pair of white tape lines that run across the field, and the space between those lines. See <SG7> for more information.
Corner – One of four 12” (304.8 mm) x 12” (304.8 mm) triangular sections of the Field in which Mobile Goals can be Placed. Each Corner is an infinitely tall three-dimensional volume bordered by the inner edges of the Field Perimeter and the outer edge of the associated white tape line.
- Negative Corner - A Corner of the field, designated by the “-” sign on the stickers applied to the top of the Field Perimeter. See <SC5> and <SC6>.
- Positive Corner - A Corner of the field, designated by the “+” sign on the stickers applied to the top of the Field Perimeter. See <SC5> and <SC6>.

Climb – A Robot action. A Robot is considered to be Climbing if it has intentionally grasped, grabbed, or attached itself to the bottom/black rung of the Ladder and/or a higher point of the Ladder. In most cases, this means a Robot mechanism will be reacting against multiple sides of a rung or vertical section in an effort to latch, clamp, or hook onto the Ladder. See <SC7> for the criteria for a Robot to be considered to have Climbed to a Level.
Ladder – A 36” (914.4 mm) x 36” (914.4 mm) x 46” (1168.4 mm) structure located in the center of the field. The Ladder has four vertical posts, and three sets of horizontal rungs at 18” (457.2 mm), 32” (812.8 mm), and 46” (1168.4 mm) to denote the three Climbing Levels. There is also a single High Stake atop the vertical post nearest the audience side of the Field, at the 180 degree mark on a GPS strip. All supporting structures, hardware, and the High Stake are considered part of the Ladder.

Figure L-2: A depiction of the heights for each Level of the Ladder.
Level – A status used for scoring and expansion rules. See <SC7> and <SG3>.
Mobile Goal – One of five (5) large Scoring Objects, each with a Stake in the center. Mobile Goals are hexagonal, with a maximal diameter of 10” (254 mm) and an overall height of 14.5” (368.3 mm). The Stake is considered part of the Mobile Goal.
Figure MG-1: A depiction of a Mobile Goal.
Placed – A Mobile Goal status. See <SC5>.
Plane – An imaginary horizontal surface that divides the vertical space between two Levels, and expands infinitely across the Field.
Possession – A Robot / Scoring Object status. A Scoring Object is considered Possessed by a Robot if a Robot’s change in direction would result in controlled movement of the Scoring Object. This typically requires at least one of the following to be true:
- The Scoring Object is fully supported by the Robot.
- The Robot is moving the Scoring Object in a preferred direction with a concave face of the Robot (or inside of a concave angle formed by multiple mechanisms/faces of the Robot).
- The Robot is holding the Scoring Object against the Floor or a Field Element.
The difference between Possession and Plowing is analogous to the difference between the terms “controlling” and “moving.”
Plowing – A Robot / Scoring Object status. A Robot is considered to be Plowing a Scoring Object if the Robot is intentionally moving it in a preferred direction with a flat or convex face of the Robot, or with another Scoring Object.
Ring – A hollow red or blue torus-shaped plastic object with an outer diameter of 7” (177.8 mm), an inner “hole” diameter of 3” (76.2 mm), and a thickness (or “tube diameter”) of 2” (50.8 mm).
Figure R-1: A depiction of red and blue Rings.
Scored – A Ring status. See <SC3>.
Scoring Object – A Ring or Mobile Goal.
Stake – A vertical ½” (12.7 mm) Schedule 40 PVC pipe (black, yellow, red, or blue) with a compliant barb at the top, used for Scoring Rings. There are ten (10) Stakes:
- Five (5) neutral Stakes in Mobile Goals, which fit six (6) Rings each
- Two (2) Alliance Wall Stakes, one per Alliance, which fit two (2) Rings each
- Two (2) neutral Wall Stakes, which fit six (6) Rings each
- One (1) neutral High Stake, which fits one (1) Ring
Stake | Image | Color | Location | Max # of Rings |

Yellow | Mobile Goals | 6 | |
Alliance Wall Stake | Red/Blue |
Field walls parallel to Alliance Stations |
2 | |
Neutral Wall Stake | Black/Yellow |

High Stake | Yellow | Top of Ladder | 1 |
Starting Line – An infinite vertical plane aligned with the outside edge (closest to the Ladder) of the white tape line that runs parallel to each Alliance Station. See <SG1>.
Top Ring – A Ring status. See <SC4>.
