5.4        BARGE

Figure 5‑9 BARGE

The BARGE is a 29 ft. 2 in. (889 cm) wide, 3 ft. 8 in. (~112 cm) deep, and 8 ft. 5 in. (~257 cm) tall structure that spans the center of the FIELD. It is made of truss structure supported by legs just outside the guardrail. The BARGE includes 6 CAGES, a red and blue NET, and all structure supporting CAGES and NETS. The horizontal truss structure is 5 ft. 2 in. (~157 cm) above the carpet and is supported in the center of the FIELD by vertical truss and supporting materials. The BARGE has three CAGE locations on each side located 3 ft. 5½ in., 7 ft. ⅜ in., 10 ft. 7⅜ in. (~105 cm, ~214 cm, ~324 cm) from mid field to the center of the CAGE.

The BARGE has three segments of lights on each side of the truss which indicate progression toward and completion of the Coopertition Bonus and the final 20 seconds in the match. One segment will light up each time an ALGAE is scored in the PROCESSOR. Once each alliance has scored two ALGAE all six segments will illuminate. The lights will flash to indicate that there are 20 seconds left in the match. At the end of the match, the lights will illuminate and then turn off 3 seconds after the ARENA timer displays 0:00 following TELEOP to help indicate to REFEREES when scoring assessments should be made.

5.4.1       CAGE

Figure 5‑10 Shallow (left) and Deep (right) staged CAGES

CAGES are 2 ft. tall and 7⅜ in. wide (outside dimension) (~61 cm tall and ~19 cm wide) rectangular structures. Each CAGE is a welded structure made of 4 steel 1 in. Schedule 40 pipes, a bottom plate, a top plate, and an eyebolt with fastening hardware. CAGES are suspended from the truss structure in specific locations as shown in Figure 5‑9 and hang at shallow or deep positions according to the corresponding team’s selection (see section 6.3.5 CAGES for details) such that the bottom of the cage is 2 ft. 6-1/8 in. (~77 cm) and 3-1/8 in. (~79 mm) from the carpet respectively. Deep CAGES are suspended using chain that is 19 links of ¼-in. Grade 43 zinc plated chain.

ANCHORS are a collection of surfaces at the top of the CAGE and chain assembly that include the following items and as shown in Figure 5‑11:

A.      the top surface of the CAGE top plate,

B.      the chain,

C.      both carabiners,

D.      the portion of the eye bolt extending above the CAGE top plate,

E.      the eye nut attached to the BARGE,

F.      the upper end surfaces of the CAGE pipes, and

G.     the inside surfaces of the CAGE pipes.

5.4.2       NET

Figure 5‑12 NET

A NET is a goal in which an ALLIANCE scores ALGAE. The NET is ¼ in. (~6 mm) knit polyester mesh, 4 ft. (~122 cm) wide by 12 ft. (~366 cm) long with a sewn cord border. It is available for purchase from AndyMark, am-5522. It is suspended from the top of the BARGE such that its lowest point hangs 6 ft. 4 in. (~193 cm) above the FIELD carpet. There is a NET for the Blue ALLIANCE and for the Red ALLIANCE.
