"<VUR5> a. The minimum acceptable form of documentation is an engineering drawing with multiple views for the part in question. These drawings may be included in a Team’s Engineering Notebook, or in a standalone appendix to the Engineering Notebook."
<VUR5> b. dictates that parts must have been physically fabricated by team members and not outsourced to a 3rd party for manufacture. The minimum acceptable form of documentation specified in <VUR5> a. does not require anything other than a part drawing, which doesn't demonstrate proof of physical fabrication. What additional documentation/proof would robot inspectors, head referees or judges require to ensure a team is not deemed in violation of rules when they actually did manufacture the part.
Related question: Some machinery at universities may not be directly operable by team members, especially undergraduates, due to the high value of a machine or other health and safety requirements. An example is a 5-axis CNC machine requiring a qualified operator but the team member can stand next to the actual operator and watch the process - is this physical fabrication by a team member?
Hoping for an answer sooner than 3-4 weeks....
