I also forgot to say that team 67 had some canburglars that seem to have been partly inspired by 548's. At msc they used polycarbonate arms, but I hear that at World's they came over to the dark side and used carbon fiber.

I'm going to try to get the students to put together a whitepaper about how those canburglars were designed and built.

Yep, our's were inspired 100% by 548's design that we initally saw when we paired with them at Livonia. We started designing a set to be used at MSC (poly carb version) a couple days later. They were 0.5s to the can due to the flexibility of the poly. After that we re-designed with carbon fiber, testing last Monday for the first time. Our testing showed them to be no slower than 250ms and much more repeatable. We knew this would be pretty fast, but feared we might be designing for an old target based on discussions with others.

Unfortunately we did not design for the can battle stalemate very well. Due to the nature of having them as part of our transport configuration required us to be able to attach them on the field very quickly. We did not have a robust attachment stategy which ultimately resulted in our arms faliure in the division finals. If we would have made it to Einstein our arms probably would have been ripped off the robot after the first tie. Which seemed pretty inevitable since we were very close to the same speed as most of the teams out there.

Our end grabbers were about $1.50 worth of PVC held on with cotter pins. I can't find video yet, but on Archimedes QF6(?-our second match) and all three SF matches we got into some epic battles due to not wanting to back up and risk ruining a 20-point auton.

We got to the cans first, (maybe not against 1538, they were pretty fast) but pretty much let the other side catch up, then the fun began. We never lost a can that we hit, even in our first SF match where we didn't put the pins in. 15 feet of stretched surgical tubing later, we even ended up with that can. For about 30 seconds (x4), this game was as fun as any other.

I've got to find those videos.

When reading through this thread and understanding how 548 Robostangs inspired and facilitated so many competing teams in the Finals by openly sharing their grabber technology, one gets a glimpse of the true meaning of co-opertition.
