 A stack of hearing aid batteries can also read 13v, but they won't run a robot. - Alan Anderson [more] |

I love the wacky frame perimeter!
What do you mean your electronics use a "terminal block system" though? I'd like to see a pic of the actual board if you have one!

I've toyed around with the idea of using 24 pin ATX connectors from PCs to connect electronics boards. I know Wago makes some similar connectors though.

So I must ask, someone commented on our robot picture that you had 12 tanks, and I see them in your CAD. However, I'm at a loss as to what on your robot requires 12 full tanks?

It mostly came down to the piston taking a lot of air though. We almost went up to 16 tanks with a different bimba piston.And we really wanted to be able to use an on-board or off-board compressor.

This year 230 had two big cylinders to hang for 10,one to fire frisbees, and another pretty big one for our scissors and we get by with 4 tanks.

We needed something with the power to push a disk into the shooter consistently so we chose this mechanism.

Re: pic: Team 4334 presents Murdock
What size cylinders are you using for that? I can't tell from the cad, but you can't have needed much bigger than .75, maybe an inch? And for the landing gear, probably something tiny, along with passive deployment? Is the landing gear only alignment, or does it have another function?

The inner bore of the pistons is .250. They were what was available locally and worked well. We opted to use the same piston for both the shooter and the landing gear for part standardization.
