Ironically I am voting that all COTS parts should be available.
Why?
I think FIRST FRC needs to question what it is and what it aspires to be occasionally as a health check.
I vote we open Pandora's box because the adults and businesses are too clever and basically have already done so.
The issue of whether we value custom fabrication and all that goes into it, and how, should be separate from simply hurting the most disadvantaged from showing up with something.
I can see someone wealthy buying themselves a victory like this. I also see that when that happens it's time for a new health check.
I do place one restriction on this. Under no circumstances should any COTS robot part vendor be allowed to know each game before kickoff. Sorry Andy - if you are involved in field logistics that might be an issue for you. This will hopefully keep the status quo for a bit longer.
