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 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 STEP file which can be imported into most 3D modeling programs

(i.e. Autodesk Inventor). This 3D model not only shows the official setup of a VEX Robotics

Competition Starstruck Competition field, but it also includes detailed models of all the individual

field elements.

For additional game-play detail, please refer to the VEX Robotics Competition Starstruck

competition manual.

For more information on reducing costs on an unofficial field construction, refer to the

accompanying Low Cost Field document located online at vexrobotics.com.

The game VEX Robotics Competition Starstruck is played on a 12ft x 12ft foam-mat, surrounded

by a sheet-metal and polycarbonate perimeter. In two corners of this field are colored PVC pipes

which denote hanging bars. The field is bisected by a Fence made of 1.26in square PVC extrusion

and plastic gussets. Foam Stars and pillow-like Cubes are placed across the field and atop the

Fence throughout.

For more details and specific game-play rules, please refer to the VEX Robotics Competition

Starstruck competition manual.

This section will outline the specifications that are most important to teams designing a robot to

compete in the VEX Robotics Competition Starstruck. 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 cant find a dimension in the specifications,

we include a FULL model of the field to virtually measure whatever dimension is necessary.

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.

IMPORTANT NOTE:DO NOT stretch Tape when applying to the Foam Tile Floor. For best results, smooth out any bubbles that form during application.

To prevent tape lines from being pulled up during competition, it is recommended that the ends of the tape are tucked into Tile seams.

Pro-Tip:If the Tiles are to be used at multiple events, it is not necessary to remove the Tape. Simply cut the Tape at the Tile seams and note the order of the Tiles when they are stored.
