Go to Post Do not treat Vex and FLL as inferior because they may not get as much exposure as FRC on these boards. Just remember, FLL has seven times more teams than FRC from twenty additional countries. - artdutra04 [more]

Re: How would your team prototype this style intake?

Re: roller intakes, this should be required viewing by everyone for crafting polycord bands or putting rubber tubing over an aluminum roller: https://www.youtube.com/watch?v=fYKsIe-yMrA

I recommend checking out 1678's other resources, tons of good stuff out there.

Re: How would your team prototype this style intake?

Consider prototyping in stages. For example:
Stage 1) quick mockup - PVC pipes and wood scraps, c-clamps and wood screws, metal scraps where needed for strength. No motors/gears/belts/chains, just manipulate parts by hand. Try multiple concepts.
Stage 2) Add quick and dirty motors/gears/belts/chains, experiment with different speeds and materials and ball compression. Refine as you go.
Stage 3) Make a more robust proto intake and hack it onto an old robot base from a previous year. Drive the mockup around chasing balls to test the pickup in a dynamic environment, try picking up balls trapped in corners, picking up a ball from a clump of balls, etc. Testing on carpet with texture and friction similiar to a tournament playing field.

Here is a link to video of 971 following this process for 2016 intake (segment from 5:17 to 6:38).

Here is a link to 971 robot in a match - view of the intake self centering action at 0:58 and 1:10
