Congrats! I think this is one of the first systems I've seen demoed that actually has a solution for triggering the touchpad despite the steel channel that's flush with the bottom. How long did the climb take?

Climbing is really quick for us - once we have the rope, its probably under 5 seconds, and getting the rope takes a similar amount of time. Total climb time is usually under 10 seconds.

Thanks!

The climb is pretty quick. The time from grabbing the rope to reaching the touchpad is no more than a couple seconds.

What motor and reduction are you running?

That's a pretty neat field element there in the background. Care to tell me more about it?

2 CIMs in a 14.88:1 toughbox. "A couple seconds" is a bit optimistic. We've ever explicitly measured it, but from videos we've taken, the whole process will certainly be under the 10 seconds we have allotted for it.

Homebrew airship with a lift and a davit that can handle a climbing robot. I'll see if one of the folks who built it can put together some information about it. It is quite neat!

The airship was built with about 10 2x4x8' boards and a few other miscellaneous pieces of wood that we had on hand. We have 200 lbs of weight on the back about 6' away from the rope to counterbalance the robot while it climbs; you can see two tie-down straps in the back that connect the weights to the airship. The straps and 1/2" bolts with wingnuts holding the 'six' sides together let us quickly disassemble the airship when needed (if you look closely you'll see we've only built 3 sides so far).

The touchpad is a Pacman-ish 10" circle cut out of 3/4" plywood with a notch around the channel. We used 3/8" bolts to mount it to the arm (each is about 6" long). There are weak springs around the 3 bolts to give us about 1" of travel to emulate triggering the touchpad.

Each GE-17075 divider has velcro on the bottom and is bolted to a vertical plastic plate that wedges between the airship sides. That way for early testing they can flex out of the way of the robot.

There is a working gear lift behind the legs of my teammate in the hooded sweatshirt. We've busted two of the GE-17064 peg points already that were made with a plastic similar to the material called out. I wonder if these are going to need to change to a more pliable material.

This could be a red flag of your design because you could get called for G15-H.

How did you break them?

They came off when we were placing gears on the lift.

Honestly, if they're representative of the ones on the field, the ones on the field are gonna break all the time. We didn't put any unusual forces on there.
