<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
Would polycord and rubber strip fall under the definition of raw materials and thus legal to use in VEX U? In previous year's VUR3
b. An unlimited amount of silicone, polyurethane, or other rubber.
polyurethane and rubber were both listed as raw materials. Since this year's VUR4 is an expansion on previous year's VUR3, we believe they should be legal.
