Game Field
A Introduction
This document will provide detailed specifications, BOM information, and assembly instructions for the Official Competition Field.
Teams who do not need an “official” field should refer to the separate low-cost field guide for cost-reduction options. Please note: this field utilizes the VEX Competition Field Perimeter (278-1501) developed by VEX Robotics. Instructions and specifications for this field perimeter are available in a separate document, and are also important for the field assembly. This document is divided up into four sections:
1. Field Overview 2. Field Bill of Materials 3. Field Specifications 4. Field Assembly Instructions
There is also an accompanying SolidWorks eDrawing Viewer file, which shows the field as a 3D solid model. Designers can take dimensions directly off this model if they require an additional level of detail not provided in this document (if you don’t see a dimension on one of our drawings, measure it virtually in the CAD model). This eDrawing Viewer file is a self contained executable which will open on most computers without any CAD software. For additional game-play detail, please refer to the VEX Gateway competition manual. For more information on cutting costs on unofficial field construction, refer to the accompanying “Low Cost Field” section of this Appendix.

Field Overview
The game VEX Gateway is played on a 12 ft x 12 ft foam-mat, surrounded by a sheet-metal and lexan perimeter. The field is divided into three sections by a stationary fence and two gates which are raised during match play. Attached to the fence and to the field perimeter are circular goals which robots may place game objects into. Spread around the field, and in the alliance starting positions are plastic balls and barrels. For more details and specific game-play rules, please refer to the VEX Gateway competition manual.

Field Specifications
Introduction
This section will outline the specifications which are most important to teams designing a robot to
compete in the VEX Robotics Competition – Gateway. Though many of the critical dimensions are
included in this section, it may be necessary to consult the separate assembly guide and 3D-CAD models
of the field for an additional level of detail (if you can’t find a dimension in the specifications, we include a
FULL model of the field – virtually measure whatever you need).
Field components may vary slightly from event to event. This is to be expected; teams will need to adapt accordingly. It is good design practice to create mechanisms capable of accommodating variances in the field and game pieces.

Field Assembly
Introduction
Tools Required
This section will detail the steps required to construct the competition field for the VEX Robotics Competition Gateway. The VRC Gateway field utilizes the “VEX Competition Field Perimeter” (278-1501). For specifications and instructions for assembling this frame, please refer to the separate “VEX Competition Field Perimeter” manual. Also refer to the separate low-cost field document, which provides lower cost options to teams not needing a full “official” competition field.
The following tools are required for assembly of the official VEX Gateway field:
• 5/32” Allen Wrench
• 7/16” Open Ended Wrench
• #2 Phillips Screwdriver (or drill with #2 Phillips Bit)
• 3/32” Allen Wrench (standard VEX Allen Wrench)
• 11/32” Open Ended Wrench (standard VEX Open Ended Wrench)

Tabs should be easily removed with a sharpknife or razor blade. When the tiles areassembled, there should be a smooth edgearound the entire perimeter.
Before assembling the foam tile floorsome tiles will need to be modified.
There are 3 main types of tiles.
Normal tiles, are unmodified. Thesewill be used on the "inside" of thefield. There should be sixteen(16) ofthese per field.
Corner tiles have their interlockingtabs cut away on two (2) adjacent edges. These will be used in the four (4) corners of the field.
Edge tiles have their interlockingtabs cut away on one (1) edge.These will be used along the edgesof the field. There are sixteen (16)per field.
(16X) Normal Tiles
(4X) Corner Tiles
(16X) Edge Tiles
IMPORTANT:Before modifying ANY tiles, check to ensureyour set of tiles NEEDS modification.
