672: What parts of the motor and motor cartridge can VEXU teams modify?

2114C
21-Oct-2020

Attached is a labeled picture of all the components of a VEX V5 Smart Motor and its Gear Cartridge: [Example Image] [Example Image]

For each individual labeled part, is it legal for VEXU Teams to do one or multiple of the following:

  • Modify the part using legal modification techniques.
  • Replace the part with a legally manufactured part.
  • Remove the part.
  • Use the part for other purposes outside of the motor (e.g. using the J type screws elsewhere in the robot construction).

I understand that the legality of modifying/replacing/removing/using elsewhere of some of these parts has previously been ruled uponin the following Q&As: https://events.vex.com/VEXU/2020-2021/QA/611

However, my goal with this Q&A is to remove any ambiguity as to the legality of modifications made to V5 Smart Motors or the Motor Cartridge.

Please see the response in this similar Q&A post:

The same response provided there applies to this question as well. The only difference is that in VEX U, any part which is "user-serviceable" may be replaced, modified, or custom-fabricated within the rules set forth by VUR3.

As noted in one of the Q&A posts that you have linked:

The primary motor case, internal components, etc are still considered "electronics" under R23, and may not be modified.
