Pneumatic Restrictions & Improvments

[Al Skierkiewicz]

Andrew,
The Cv, port size and tubing size are limits placed on design because this is an engineering challenge as much as a robot competition. These limits are in the same group as the limits on size, weight, electrical power source, quantity of motors, etc. They are also in place for those teams that lack a pneumatics mentor to show them proper procedures and safety methods. For teams that have sufficient resources to own more than one of something, you need to always keep in mind that there are a fair number of teams that can't afford even the simplest of parts and tools let alone a second compressor.
As such, I would like to suggest to others reading this thread that items claimed as having been ruled legal at an event or covered by a Q&A response may in fact be not correctly stated. The post may not give all of the available information surrounding that particular event. (see Mark McLeod and Jon Stratis' posts that relates the true info.)
mk.32, two compressors are not legal in 2014 and actually never have been even before we allowed off board compressors. The "one and only one compressor" language is very specific.
We will consider other suggestions i.e. high flow exhaust valves.
