Please make sure to read the rules G4 outlines this one pretty clearly.

As the rules are currently written this is in fact an issue as a dead robot holding a ball would shut down their entire alliance. The official Q&A will answer this question so we'll be getting some clarification soon.

I think the max is 70. 10 for one assist, 10 over the truss, 10 for a catch, 30 for the third assist, and then 10 for scoring. Although it'll be uncommon thats what I think a perfect run could get you.

You don't get 30 more points for the 3rd assist. Just 30 total assist points for 3 assists. That means 60 is the max. 10 truss pass, 10 catch, 10 high goal, 30 assist.

By definition, yes. Although I'm begging for an amendment to that.

This may have already been answered but does anyone know the mass of the ball? preferably in Kg?

also the I.D. and wall thickness of the latex surgical tubing in KOP?

Thanks

One thing that I think a lot of people are confusing is calling the game easy vs basic (or any other related synonyms). Easy implies that the game is not difficult, which is definitely false. It is still a challenge to pick up and launch such a large object with only 20" of space to work with outside the robot, so this year's game is definitely not easy nor should teams take it lightly. However, no FRC game is ever really easy. I don't necessarily think this game is as hard as past years but it is still a challenge and just because it might be a bit easier doesn't mean that it's worse in that sense. Furthermore, this game requires robots to cooperate with their alliance partners. This is the real strategic part of the game, using heavy defense while not neglecting your own ball/team. Assists, passing, all of these elements provide the challenge of the game that is hard to prepare for off-field. I think this game presents a new challenge; instead of figuring out clever ways for the robot to pick up/carry/launch game elements, it requires teams to be smart drivers. They need to be where they're needed when they're needed, and have to work with both their partners.

However, I think most of us can agree that this game is more basic. There's a whopping one field element that can be manipulated by robots and it's recycled from previous years, just smaller. The goals are pretty much the same as last year's. The only mystery is the truss, which nobody seems to know if it's cost effective or not, or if that's even a priority. The hot goal is new I guess, but provides only a five point difference and is pretty negligible if you ask me. Assisting is this year's real focus if you ask me, but let's be honest doesn't make for the most exciting game at a first glance. The balls don't accelerate to super high speeds, or go long distances when passing. Most passes will be rolled or lightly launched and the only thing that changes is what robot is possessing it. Now I understand that many people will argue that this is still exciting to watch, and I agree to an extent. This will be a fun game for FIRSTers (is that a thing?) to watch. People who understand the game, and know how hard it is to build a robot, can relate to all the different game strategies, etc. But to an outsider who hasn't gone through the struggle of actually having to play the game, it's a boring game. The shooting is cool, sure, and I guess the ball moves a lot, but it just pales in comparison to previous years. Ultimate Ascent comes to mind as a year that was thrilling to watch. Of course FIRST can't always make a more and more thrilling game every year, but this game just seems leaps and bounds behind.

Overall I don't think this game is a bad one, it's just more exciting "under the surface" when you get into strategy, defense, etc compared to the admittedly lackluster appeal to casual viewers. Until the game is played we really won't know how much better/worse it is than previous years.

I'm curious, if people wouldn't mind sharing, what type of drive trains are you looking at? I thought a 4 wheel tank drive (with wheels near the corners) would be good, but I've been told that turning with this system can really shake your robot's frame and wouldn't be a good idea, does that make sense?

This game definitely reminds me of the kinds you might play as a kid in order to get everyone included. "You must pass the basketball to every player before you can shoot." I'm sure people have done things like this. While I'm all in favor of being inclusive and I know that's a good thing especially after last year's game was so difficult, it seems that this is, as you say, taking things a bit too far. While this does help the rookie teams to get to do something, the higher teams who have worked hard to become really good are hampered by the fact that they can't handle the whole thing if necessary. I foresee a lot of problems in the first few rounds of regionals if 2 bots are dead in one alliance.

Oh well, it should still be very fun an interesting.

I have seen several posts about ball weight. I know this matters, but we need to know the pressure inside the bladder so we can collect data on how much the ball will compress. The data in 2014 BALL Inflation and Maintenance Guide is not very exacting.
6. Inflate the BALL so that the zipper appears as in the “Properly Inflated” figure below. The BALL
on the left is under-inflated, while the BALL on the right is over-inflated. When properly inflated,
the zipper will be able to be pulled and closed, not too hard, not too easy.

The ROBOT must satisfy the following size constraints:

the total length of the FRAME PERIMETER sides may not exceed 112 in. (see Figure 4-1 for examples),
a ROBOT may not extend more than 20 in. beyond the FRAME PERIMETER (see Figure 4-2 for examples) (see G24), and ...

Does everyone agree that this means 20 in. in multiple directions at the same time?? Looks like that to me. --- sorry if already discussed, searched and no find.

It has already been answered somewhere but teams are getting between 2.5 and 2.75 lbs for an inflated ball. That works out to be roughly 1.1 to 1.2 kg.

I'm not sure what the specs are for the surgical tubing but I'm sure if you look at the KoP checklist and find what the type of surgical tubing it is then you can do some quick research on it.

I'm hoping I am terribly wrong, but it looks like this year will be even worse than 2012 when it comes to teams sabotaging alliance members to reduce their rankings. All you need is one team holding onto their ball after autonomous, and the whole alliance is relegated to a maximum of 50 points, even if the other two teams are the best teams in the world. If nothing is gained in auto but driving points, then the maximum becomes 30 points.

Of course, you could force the team to drop the ball, but things will still end up being a bit ugly.

Very un-GP? Yes, but what can you do at this moment without a rule change?

They define it vaguely because there is no definite psi that the balls are inflated to. They are filled by eye/feel of the event crew and field staff. You will experience variances during competition, and should plan for these variances. I would suggest using your own judgement; fill the ball to the point where it's somewhat difficult to close the zipper - this is your high end, then deflate to where it almost seems too loose - this would be your low end. Then expect to see anything in-between at competition.

You want specifics? Too bad. I became an expert trackball inflator at the Championship in 2008, and there is really no science to it. Basically, just going by the zipper.

The video itself even shows people climbing it, along with the fact that the interior struts (the angler things) are separated much more wide then in a normal truss.

The truss is quite likely a COTs of its own in the entertainment industry. I'm not a roadie and I only play one on tournament days. These truss items are used to carry the lighting for a show up near the rafters and lower them to stage level so that things can be adjusted or fixed without extreme alpine skills involved.

Speculation about how sturdy they are for the job they're doing should die out once you realize that anything placed on the field is subject to climbing. I think the GDC and FIRST got a certifiable scare last year due to all that protoplasm crawling all over those skeletal pyramids. A rope? No way GDC wanted to see an FRC version of the Wallendas' act.
