Pneumatic

I got the system done last night... Layout wise. Ball valve before the cylinder (to make safty person happy). bleed valve at the ass end of the manifold...

Just a few stills of the thing... Let me know what yall think.

The manifold has a wall thickness of at least 3/8 if I need to loose some weight how thin can I make the walls on this thing and it still be safe?

Very nice Im interested as to how the bodyll look, any clues just yet?

Looks good!

But a little tip, dont put your hand in front of pressurised gas... e.g. dont put it in front of the exhaust valve. Any small particles in the gas will be injected into your skin.

I cant for the life of me see a reason for the ball valve in between the Burkert valve and the ram......very odd!

Reducing the manifold thickness to perhaps a min of a 1/4 between any internal drilled holes and the outside may well be fine.

Persuading the safety man that the ball valve isnt reallly needed would help.......

Chad .......I assume that your working towards this ...
7.6. All pneumatic components within the robot must be rated or certified for AT LEAST the maximum pressure in that part of the system. You may be required to show rating or certification documentation on ANY component in your system.

Id like to point out that the burst disc pressure rating on paintball bottles is fairly high ........1,800 psi plus as a norm.
So .....the ratings of your valves and fittings should be at least that of your burst / rupture disc.
The addition of a 1000 psi pressure relief valve makes things simpler.

BTW... Whats the rating of your vent / dump valve?

Ewan, The body is going to look something like Phillips bot. The outside armor / shell will be shaped kind of like a pyramid. Front will have something around .300 Ti with the rest about .125. The base plate is 17wide x 12Long. So it will be really wide. I like this because 1- It will be easy to drive with 4 wheels and 2- It will give my arm alot or area to catch the other bot. Also, my drive will be http://banebots.com/osc/product_info.php?cPath=36_63&products_id=224http://banebots.com/osc/product_info...roducts_id=224 two of them @ 11.1v then belts to the front wheels.

Woody - ya I know, I dont like that ball valve! But that guy said he wants me to have it. Why, I am not sure... But maybe because that this is the first FP flipper in the US (as far as I know) it is just something that they dont understand yet.

That bump vlave is like 1500 or something, I dont know. I just had it in my shop, worked out well. I dont HAVE to get the parts certified, that is why I made them overkill, to get around that rule. But if I need to save weight I will make it weigh less by milling off a few 16s from each side.

The dump looks similar to the one we use in Merlin, weve used it for about 2 1/2 years in hundreds of fights on FP and never had a problem. I did see after about 6 months that it was only rated to about 300psi, but has never failed me even after a fight when its been solid ice! saying that tho it could be a different model.

The only posistive thing i could see about the valve between burkert and ram is that it would stop a miss fire if you were to open the bottle too quickly. Although personally i would have put it just after bottle as the bottle valve looks abit small and fiddly.

@ Alan
The flow from the paintball bottle is via a needle valve ......hard to open it anyway other than SLOW and once open its flow can only be considered .......meeker.

@ Chad
Id try very hard to get the ruling on the ball valve changed.

Tsk ....spelling!
Meagre ....not meeker!

Got some work on the base plate done today. 18 build days left! Pic on profile.
