After seeing how discs were being scored in the week 1 regionals we decided we could add a simple 10 point hang and score more than the 20 "extra" climb points with discs in those last 45 seconds.

With the climber we were right near 120lbs. Removing it allowed us to "put weight" into other systems and make them better, increasing the overall scoring potential of the robot.

In addition the climbing was always extremely nerve racking and we weren't at the point where we had confidence we wouldn't fall. Taking it off and eliminating the possibility of a tournament ending face plant was a side benefit of our decision.

We kept working on the climber but realized it was never going to meet our speed metric. In addition we'd need to re-lighten mechanisms back to their original config to put it back. We decided the robot would always be better overall without it.

It was a cool climbing method that we spent A LOT of time on. It's too bad it didn't pan out but it was fun to work on and taught us a lot.

Do you at least have some raw footage of your climber? Or do you have any plans to put it back on during the offseason? I would love to see it in action (and not just the edited version in the release video).

Just out of curiousity, what were some of the additional improvements you made?

I believe the biggest one was their hopper. They have a cycling hopper that feeds from the lowest feeder slot instead of the middle. This makes it more reliable and much faster to cycle faster.

How did the extensions near the ground pickup work, the ones used to gather all 7 discs in autonomous? Did it extend out as the match started, or was it always in the extended position? I never got a chance to look at it closely...

They extended out as the match started, I seem to recall.

118 should do an IRI "reveal" video to show their current setup (or perhaps IRI changes).

I'd also love to see some pictures of their climber. I stopped by their pit in St Louis to see their floor pickup, but I've never seen the climber up close.

Their 30pt climber was taken off due to weight issues.

I never got a chance to see this robot in action, in person.
I get 2 consecutive weeks in July and our robot gets to "sit" next to it, in between events.:)

Could anyone explain to me how their hopper worked? Also, if any one has clear photos of it, that would be amazing!

What happened to full court shooting?

They had an elevator-like hopper. It was lowered when they were loading it, and elevated it up to the shooters height.

Do you know how they got Frisbees into the hopper? It seemed like they pushed them in from the bottom, but I couldn't figure out how they make room under the other Frisbees.

Not sure I follow?

The shape of the frisbees was such that if you slide a moderately thin piece of lexan (or similar material) towards the frisbee, the frisbee would sort of hop on for the ride. Combine that with a roller on a top, and you've got yourself an intake.
