2014 Rules Changes
 

Some quick ones I noticed are more legal batteries and new vertical projection rules.

A match is now two and a half minutes.

Re: 2014 Rules Changes
 

Autonomous is only ten seconds.

Re: 2014 Rules Changes
 

Championships has 3 selection rounds, 1-8, 8-1, 1-8, 4th team doesn't have to play in any round.

Re: 2014 Rules Changes
 

Maybe a new rule??

EDIT: Not a new rule. Thanks EricH for the correction

Re: 2014 Rules Changes
 

Recycled rule, at least 2 years old.

Only 10 second? Wow.
Instead of FIRST decreasing autonomous mode time, they should be increasing that time. Its more of challenge for teams to accomplish.
FIRST should keep Autonomous at 15 second, though in my opinion it should be 30 seconds. That way a team is forced to do something good with their robot or else they will be missing out on a lot of points.

Re: 2014 Rules Changes
 

There is no end game this year, although I don't know when the last time this happened was.

Re: 2014 Rules Changes
 

Can we use other alliances balls? What about entering another bot's perimeter for an assist, if it is on our alliance?

Re: 2014 Rules Changes
 

Start by reading the Manual, please. If you had read G11, you would have discovered just how bad the penalty for using your opponents' ball is. (It's NOT pretty.)

For the other one, there is no rule specifically against it. However, you only get 20" outside your own perimeter to work with, per R3-B.

Re: 2014 Rules Changes
 

I believe that this is new:

Re: 2014 Rules Changes
 

Thank you.

Re: 2014 Rules Changes
 

I saw that too. Make your bumpers robust. If they go out of the bumper zone, you get DISABLED! :yikes:

Re: 2014 Rules Changes
 

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?

Re: 2014 Rules Changes
 

Theyve had some sort of end game play since 2008 (When I joined) and I'm pretty sure they had one in 2007. So for at least 6 or 7 years.

(End game being defined as the last twenty seconds where a robot hangs, positions itself, fires a mini robot, scores extra points using special objects like super moon rocks or colored frisbees, placing track balls on overpass, etc)

Re: 2014 Rules Changes
 

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?

Re: 2014 Rules Changes
 

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.

Re: 2014 Rules Changes
 

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

You can't get assists in autonomous.

Re: 2014 Rules Changes
 

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

Re: 2014 Rules Changes
 

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

Re: 2014 Rules Changes
 

A quick search found this valve:
http://www.mcmaster.com/#6425k12/=q4ehnb

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

Re: 2014 Rules Changes
 

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

Re: 2014 Rules Changes
 

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

Re: 2014 Rules Changes
 

I did. In the first post.

Re: 2014 Rules Changes
 

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

Re: 2014 Rules Changes
 

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?

Re: 2014 Rules Changes
 

I meant mechanical over pneumatic.

Re: 2014 Rules Changes
 

During the autonomous period, do we have to start with the ball within the frame perimeter? Can we set it next to the bot and program the robot to pick it up?

Re: 2014 Rules Changes
 

I suggest reading rule G5, and telling me what "touching" means.

Re: 2014 Rules Changes
 

Touching: arousing strong feelings of sympathy, appreciation, or gratitude. Kind of like New Math. How you feel about it is more important.

Re: 2014 Rules Changes
 

Nice. Anyways, to answer the question, I think that you can program it to pick it up as you are allowed not to start with the ball. The only thing then is that the ball starts in the center of the field, not next to you.

Re: 2014 Rules Changes
 

Oh? I suggest re-reading G5 again. You are allowed to not start with a ball touching you, but in such a case the ball is either staged in the white zone (goalie or missing robot) or not on the field at all (goalie, missing robot, team not starting with a ball).
