<VUR4>T-Slot Aluminum

<VUR4> Fabricated Parts must be made from raw materials. For the purpose of this rule, a “raw material” is any material that would not be considered a “pre-fabricated” part, i.e. has not undergone any of the fabrication techniques listed in <VUR3>. a. Standard raw material finishing processes, such as extrusion, heat treating, or anodizing, are not considered pre-fabrication

https://www.robotevents.com/VEXU/2020-2021/QA/613 In previous year's Q&A, slotted aluminum would not fall under raw material

Milling slots into a piece of aluminum bar stock would be legal, but buying pre-slotted aluminum would not. The goal of VUR3 is to encourage Teams to explore fabrication techniques of their own. Similarly, pre-drilled or extruded metal, such as angle aluminum, is not permitted

Since this year's rule specifically allows extruded material as raw materials, does this mean slotted aluminum, angle aluminum etc would be legal?

Answered by committee

Yes. As you have noted, in previous years, "extruded metal" was explicitly referred to as not permitted. In the current Game Manual, "extruded metal" is explicitly referred to as permitted.

If you have a specific product that you would like a ruling on, please feel free to submit a link to a product website. In general, if something is referred to by a manufacturer as "aluminum extrusion", then it is most likely legal.
