2014 Rules Changes

[Whippet]

I believe that this is new:

G20: ROBOTS must be in compliance with Section 4.6: BUMPER Rules throughout the MATCH. Violation: DISABLED

in regards to the horizontal extensions. you can go out up to 20in in any direction correct? But does that limit you to one <20in extension at a time in the 6in cylinder? Or can you have more than one as long as they aren't 20in?

The six inch cylinder is an entirely different rule.

Vertically, any extending parts going higher than 5 feet can only be extended in the Goalie Zone and must fit within a 6" vertical cylinder.

Horizontally, you can extend 20 inches normal to the edge of any frame perimeter member. Height doesn't matter as long as it's under 5 feet. I have just read the rules but I do not remember anything limiting how many extensions are out at one time.

The six-inch cylinder rule only applies to vertical extensions.

So, let's say all 6 robots miss their auto points and the balls all stay on the field. How will the refs keep track of all the balls and assists?

Or will assists not count until all the auto balls have been scored? If this is the case, wouldn't it be better to have some of your alliance partners not even do auto so that you can get assist point in Tele-op quicker?

You can't get assists in autonomous.

I'm still in disbelief over this one, even after re-reading the rules and ctrl+f searching

The ridiculous Cv limit on pneumatic solenoid valves has been removed entirely

By Cv limit, do you mean flow rate? If so, this is big.

A quick search found this valve:

1/8" inlets with 1.0 Cv. Last years limit was .32 Cv.

Has no one yet said that matches are now 2:30, not 2:15?

I did. In the first post.

Has anyone calculated whether this would actually improve the flow rate with the diameter tubing that is required?

For a $130 each, would the improved performance really be worth it over a mechanical solution?

I think that it is just an example of a valve that is no longer illegal, not the best option. Also, what sort of mechanical solution exists for a small flow coefficient other than a larger flow coefficient?
