Does your pneumatic system have any leaks? 120 psi shouldn't take 1 minute to build.

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

I can tell you it does if you have a lot of air tanks XD

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

You could always fill your tanks before the match too

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

We carry 256 cu in air storage. Stroking a 2" x 24" and (2) 1.5" x 12" cylinders consumes A LOT of air. We have to wait a full minute.

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

How many tanks are you using to store that air?

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

We've reduced our stored air capacity to 210 cu in.
(2) 41 cu in plastic, (2) 32 cu in ss and (4) 16 cu in ss tanks, tucked into various spaces. The waiting time is spaced between the strokes. 10 sec here, 10 sec there.
We'll post video later today.

Check the dimensions of your top box. It looks too tall to me. I'd hate for you to reach a competition where you didn't have the same room to extend inside the pyramid at the top.

Nice work on the 'bot, though, staying tuned for video. :]

We were using 888's pyramid and we noted several dimensional deviations.
In the photo we are looking at that top clearance. We were well below the top of the upper bar.
That experience made us aware of our sensitivity to dimesional tolerance.

Have you explored using a dual working pressure solution? Actuating the unloaded portion of a cylinders movement (in this case the extension) with lower pressure air, say 15psi, can result in some huge air savings while still allowing you to actuate at a full 60psi in the loaded direction (retraction).

It does require more overhead in the form of additional regulators, tubing, fittings, solenoids etc., but may allow you to climb faster and/or reduce your storage requirements.

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

Isn't it disingenuous to say that it climbs in 30 sec. if it cannot work without waiting for the air tanks to refill?

Am I missing something?

Re: pic: 2528 RoboDoves 30 sec, 30 point climb
 

Yes, we did.
Our concern was risking rotation of the 2" cylinder's main hook.
We operate at 45 psi and the hook is nicely firm; 20 psi doesn't have the same resistance to twist.
We couldn't find a 24" stroke gas spring.

Deceptive maybe. not disingenuous.
