The part is not in either the legal parts, nor the illegal parts list. A similar item is found in legal parts listed as 228-2500-1934, we would assume 228-3201-1934 should be legal as it's just different color of the legal version. But an official clarification would be appreciated.
The Q&A is closed for the 2021-2022 season. Any rule changes or clarifications pertaining to the 2022 VEX Robotics World Championship will be included in the April 5 Game Manual Update. Teams attending VEX Worlds who wish to pre-submit questions for the driver's meeting should have received a contact form via email; if not, please contact your REC Foundation Team Engagement Manager for more information.
Official Q&A: VIQC 2021-2022: Pitching In
989: <R7> Is 228-3201-1934 Legal?
Answered by committee
Yes, this is legal.
The Legal Parts Appendix includes the following introduction on page 2:
Because VEX IQ parts come in many colors, any colors depicted in the renderings below may not necessarily reflect the colors of the final physical products.
This also means that if a part has the same Unique Part Identifier (i.e. last 3-4 digits) as a part listed in this Appendix, but a different Color SKU Identifier, then it is still considered legal. This article explains the VEX IQ part number system in more detail: https://kb.vex.com/hc/en-us/articles/360044274672-Color-Part-Number-Info-for-VEX-IQ
We will be sure to clarify this further in a future VIQC Legal Parts Appendix update.
