It barely fits right when it's about to grab the lowest bar, but is fine after that. The biggest issue we have is putting too much pressure on the lower claw to pull it off (we actually broke some welds on our test pyramid. Hopefully FIRST will have stronger pyramids)

Just amazing.

One of the coolest things I've ever seen a FRC robot do!

Please post updates as you continue to refine this system, I'm just excited to see it get even better!

I really have my doubts that that will fit in a 54" cylinder with bumpers on it.

That being said, you robot is awesome!

We designed it carefully so that it fits in the 54" cylinder until it touches the tower where the 54" cylinder can be in any orientation.

you guys aren't violating G23-1 B. when you intiailly start your climb, are you?

"While in contact with the PYRAMID, a ROBOT

B. may not extend any part of itself beyond a vertical plane defined by a perimeter offset from the base of the PYRAMID by 54 in., see Figure 3-5b and Figure 3-5c."

We would have to try very hard to get the robot to violate that rule. It's designed to prefectly fit within a 54" vertical cylinder when the robot is cantilevered horizontally and the free claw vertical or angled towards the pyramid.

It's hard to tell, but is there any anti-backdrive in the gearboxes? It seems like they might backdrive and you could sag down below the 2nd rung after power is cut if you're not folded all the way up.

It's a very cool system, I was really hoping someone would make a flipper climber!

Tumbleweed!(Our team nickname for the idea) This was a climbing idea I was sad to see go off of our list.

So happy someone did it! And it looks like you guy did it really well.

The total ratio on those arms is (if I remember right) around 1:900. We can stay in place without a problem if we're fairly close to vertical without a problem.
