 The Chairman's award is about doing what you can to strengthen the FIRST community. It doesn't require money to simply lend tools, wise advice or a hand. - Koko Ed [more] |

Re: pic: Championship Upgrade
Yes - it's to tighten the chain. The problem was in the initial CAD layout we left 4.5" for it but didn't have a particular design in mind. Just seemed like 4.5" was enough. Toward the end of the build season we added a conventional turnbuckle style with eye bolts. This came out 5.5" long and the elevator wouldn't travel quite far enough. We had to jockey the bot around when totes were coming down the chute.
After week six, our lead mechanical mentor came up with this design to get the 1" of travel back. Now the totes fall out of the chute into the bot just as sweet as can be. Our OPR went from 85 to 104. The lesson is, saving a couple of seconds many times in a match ends up being a big deal.
