Thanks for posting this paper team 234!
I wanted to follow-up with a link to the Automation Direct website showing where to purchase these new lighter-weight, less-expensive NITRA pneumatic parts:
Special Purpose Push-to-connect Fittings
Accessories
And don't forget that each team has a
$35 voucher from AutomationDirect.com for 2017, so several of those parts could be yours for FREE ($6 flat-rate shipping not included). We also sell about 15,000 other industrial automation products, many of which could also be useful on your 'bot.
Good luck with Steamworks!
