Building Materials??

Is poly carbonite the only thing other than official Vex parts that can be used on the competition robots? Could we make a part out of aluminum to use?

Poly carb is the only structural piece.
Rubber bands, string and zip ties. All have guidelines but are legal from any seller.

The Starstruck rule book lists all this out. If I recall correctly, there are a few other non-vex things you can use. But rather than going by memory, why not go to the source - the rulebook?

Correct. Only the 12x24 sheet of polycarb (expanded definition now) can be used. All others must be in the Vex EDR systems list of parts.

And no copying the Vex parts with your own puncher or C&C. I think they copyrighted the designs and the material must be the same. Plus there would be no revenue going their way…

Just clarifying, that’s what I thought.

Before spreading false or incomplete information, here is the exact quote from R7 in the game manual. In fact, there is a whole lot more than polycarb that is legal.

<R7> Robots are allowed the following additional “non-VEX” components:
a. Any material strictly used as a color filter or a color marker for a VEX Light Sensor.
b. Any parts which are identical to legal VEX parts. For the purposes of this rule, products which
are identical in all ways except for color are permissible. Note: It is up to inspectors to
determine whether a component is “identical” to an official VEX component.
c. Any commercially available #4, #6, #8, M2, M2.5, M3 or M4 screw up to 2" long, and any
commercially available nut and/or washer to fit these screws.
d. Teams may add non-functional decorations provided that these do not affect the robot
performance in any significant way or affect the outcome of the match. These decorations
must be in the spirit of the competition. Inspectors will have final say in what is considered
i. Anodizing and painting of parts would be considered a legal nonfunctional decoration
ii. Any guards or decals must be backed by legal materials that provide the same
functionality. i.e. If your robot has a giant decal that prevents Scoring Objects from
falling out of the robot, the decal must be backed by VEX material that also prevents the
Scoring Objects from falling out.
iii. If using the VEX speaker (Part #276-1504), the chosen audio must not be distracting
and must be in good taste. The Head Inspector and Head Referee will make the final
decision on the appropriateness of the audio.
e. Any non-aerosol based grease or lubricating compound, when used in extreme moderation on
surfaces and locations that do NOT come into contact with the playing field walls, foam field
surface, game objects, or other robots.
f. Non shattering plastic from the following list; polycarbonate, acetel monopolymer (Delrin),
acetal copolymer (Acetron GP), POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all
grades), Polypropylene, FEP; as cut from a single 12" x 24" sheet up to 0.070" thick.
i. Plastic can be mechanically altered by cutting, drilling or bending etc., but it cannot be
chemically treated, melted or cast. Teams may heat the polycarbonate to aid in
g. A small amount of tape may be used for the following purposes:
i. For the sole purpose of securing any connection between the ends of two (2) VEX
ii. For labeling wires and motors.
iii. Teflon tape solely for the purposes of preventing leaks may be used on the threaded
portions of pneumatic fittings.
iv. For securing and retaining a VEXnet key to the VEX ARM® Cortex®-based
Microcontroller. Using tape in this manner is highly recommended to ensure a robust
h. Hot glue for securing cable connections
j. A USB extension cable may be used for the sole purpose of remote mounting of a VEXnet key.
The key must be mounted in the following manner.
i. The VEXnet key must be mounted such that no metal is touching the key above the
VEXnet logo.
ii. We highly recommend that no metal may be within 2” of the top of the VEXnet key.
k. An unlimited amount of 1/8”, braided, nylon rope
l. Commercially available items used solely for the purpose of bundling or wrapping of 2-wire, 3-
wire, 4-wire cables, and pneumatic tubing, for the purposes of protection, organization, or
management are allowed. This includes but is not limited to electrical tape, cable carrier, cable
track, etc. Note: it is up to inspectors to determine whether a component is serving a function
beyond protecting and managing cables.
m. VEX IQ pins used solely for the purpose of attaching VEX Team Identification Number Plates.

I’d especially like to clarify that Polycarbonate is not the only plastic that can be used, but rather
