Is it legal to use old game elements

We are currently having a robot tipping issue and are trying to solve it by adding weight onto the back of our robot. We were wondering if it was legal to use the plates from the mobile goals from “In the

The GDC stated that using the plastic from “Turning Point” was legal and were wonder if that ruling applies to other game objects as well. Thanks for all the input in advance!

Only reason flags are legal is because they are in spec polycarb, nothing to do with them being game peices


I would rule not, as they are not parts meant for building. Similar to trophies.


I thought you could use trophies as building materials also do you have specific rules that would apply to this?

You are not allowed to use vex products not intended for construction.


Yes, give me a minute.

Xenon, I got it.

<R5> Robots are built from the VEX EDR system. Robots may be built ONLY using official VEX EDR 
components, unless otherwise specifically noted within these rules. Teams are responsible for pro-
viding documentation proving a part’s legality in the event of a question. Examples of documentation 
include receipts, part numbers, official VEX websites, or other printed documentation.
a. Products from the VEXpro, VEX IQ, or VEX Robotics by HEXBUG product line cannot be used for 
Robot construction, unless specifically allowed by a clause of <R7> or cross-listed as part of the VEX EDR product line. For example, the Rubber Shaft Collar (228-3510) is a VEX IQ component 
that can be found on the VEX EDR “Shafts & Hardware” page, and is thus legal: https://www.
b. VEX IQ pins and corner connectors used solely for the purpose of attaching VEX Team Identifi-
cation Number Plates are permitted.
c. Official VEX EDR components which have been discontinued are still legal for competition use. 
Teams must be cognizant of <R6> if attempting to use a discontinued part.
d. Any parts which are identical to legal VEX parts are permitted. For the purposes of this rule, 
products which are identical in all ways except for color are permissible. It is up to inspectors to 
determine whether a component is “identical” to an official VEX component.
e. Components obtained from the V5 beta program, including V5 beta firmware, are not legal for 
competition use.
i. All V5 beta hardware can be identified by its lighter gray pre-production color. Robot 
Brains, Robot Batteries, Controllers, and Vision Sensors from the V5 beta have a “BETA 
TEST” stamp on them. Smart Motors and Radios do not have this stamp, but can still be 
identified by color.

Using VEX apparel, competition support materials, packaging, or other non-robot products on a VEX Robotics Competition Robot goes against the spirit of this rule and is not permitted.

This is directly from the game manual.


Since “competition support materials” isn’t defined could you not argue that the weights don’t count as “competition support materials” and argue that the pieces are vex products that don’t cont as or that side note?

Please argue for me why a game element does not support competition.

However it also says “other non-robot products”, which clearly the game elements and trophies are…

Adding weight is always a last resort. Can you move things to the front to help? Have you tried flip out wheelie bar wheels? Move motors down and use lightweight chain to drive upper mechanics?


Are the steel plates not compatible with your robot? I don’t really see a reason to add the mobile goal weights instead of steel plates.

or box full of steel screws… seen that… box made of vex legal parts :slight_smile:

I saw a team just zip tie like 20 hs axles to the front of their robot
