Re: Opinion Poll: Proliferation of Prefbricated Parts

To me, it's a slight bit "Chief-delphi-ish" to stroll through this thread and see all the team numbers; a good 50-60% in the <1000's.

5511 is a mildly successful team, rookies in 2015. We had the opportunity to go to champs last year and it really opened our eyes to the possibilities and abilities of some of the greatest FRC teams. Like many other teams, we had to make brackets for our lift - and ended up using stepper bits and whatever steel plates were at Home Depot. Garage-built, low resource, student-run team down in NC. We have the RTP right next door but hadn't tapped into that until this year. The only COTS we had was the KOP because we didn't have the money or know-how to make our own.

A few of the other teams in our area have also had the chance to go to champs and see what some of the "champs-achieving" teams do. Their take-away was very different than ours: COTS COTS COTS. 3 CIM dogshifters with PTO from WCP puts you quite a bit close to that $400 limit. All vex bearing blocks with tensioners and versatubing. While these are great resources, they personally feel like overkill for a COTS part.

Our take-away from champs was different. We purchased the cheapest CNC router on the market (X-Carve at around $1100; took lots of convincing) and are relatively happy with the results. Getting the machine to breeze through aluminum was a challenge, but I can personally vouch for the learning process inspiring the other students. Getting into CAD, CAM, and all of the aspects of CNC machining for our freshman has been incredibly value - but they don't realize it yet. We could have just bought versatube for the rails and the crazy selection of gussets in order to be very competitive very quickly. Now, however, our students have skills applicable in jobs later on in life. They have learned design that isn't simply 'slap it together.'

Your opinion on the matter is your own, but just keep in mind that there are ways to achieve similar results with very low resources and some dedicated learners.
