5.2       FIELD

Each FIELD for REBUILT is an approximately 317.7in (~8.07m) by 651.2in (~16.54m) carpeted area bounded by inward facing surfaces of the ALLIANCE WALLS, OUTPOSTS, TOWER WALLS, and guardrails.

Figure 5‑2 FIELD boundary in pink

The FIELD is populated with and surrounded by the following elements:

-        1 OUTPOST per ALLIANCE,

-        1 HUB per ALLIANCE,

-        1 TOWER per ALLIANCE,

-        2 DEPOTS,

-        4 BUMPS, and

-        4 TRENCHES.

The surface of the FIELD is low pile carpet, Shaw Floors, Philadelphia Commercial, Neyland II 20, “66561 Medallion.” Neyland II carpet is not available for purchase at this time, and the closest equivalent is Shaw, Philadelphia Brand, Profusion 20, Style 54933; see results from evaluation in this blog post.

Carpet edges and seams are secured with 3M^TM Premium Matte Cloth (Gaffers) Tape GT2, GT3 or comparable Gaffer’s Tape. Tears, rips, and damage to the carpet may be repaired with the same styles of tape and ROBOTS must be prepared to operate on surfaces made of carpet, tape, or combinations of both materials as repairs are made through the course of competition.

Guardrails form the long edges of the FIELD. Guardrails are a 20.0in (50.8cm) tall system of transparent polycarbonate supported on the top and bottom by aluminum extrusion. There are 4 gates in the guardrail that allow access to the FIELD for placement and removal of ROBOTS. The gate passthrough, when open, is 38.0in (96.5cm) wide. Gates are closed and shielded during the MATCH.

There are 2 versions of guardrails and DRIVER STATIONS used for competitions. 1 design is the Welded FIELD which is reflected in the 2026 Official FIRST FIELD Drawings & Models. The other is designed and sold by AndyMark. Table 5‑1 and

Table 5‑2 illustrate which areas have each kind of FIELD. While the designs are slightly different, the critical dimensions, performance, and expected user experience between them are the same unless otherwise noted. Detailed drawings for the AndyMark design are posted on the AndyMark website. All illustrations in this manual show the traditional Welded FIELD design.
