General Updates


This note is from Frank Merrick, Director of FRC Hello teams! For this part of today’s update I wanted to include a note directly from me, rather than generically from the Game Design Committee. I lead the GDC, so all information released by the GDC ultimately has my OK, but I thought it might help to let you know I’m writing this particular note myself.

There has been significant discussion and some anxiety on the Chief Delphi forums over what some are calling ‘The Noodle Agreement’, in which the two alliances in a Recycle Rush match could agree to collude, legally under the current rules, to simply drop their own litter on their side of the field, then not touch it, effectively giving both alliances easy bonuses to their score. The GDC talked about this specific possibility before the game was released. We actually talked about two different ways alliances could collude regarding noodles.

We had briefly considered, then quickly rejected, having the opposing alliance receive a bonus for ALL litter not in scoring position in the possession of an alliance. In other words, an alliance would have received a bonus for litter still sitting in the other alliance’s bin. This was rejected right away, as we realized passive collusion would be easy – both alliances simply needed to agree to not touch the litter in their own bins, and it would be immediately obvious if one alliances was not holding up their side of the bargain. This led to the current rules, in which any litter remaining in the bin has no effect on the score.

The second form of collusion we had discussed was what is being talked about on the forums – both alliances dumping all their own litter on their side of the field and leaving it. This form of collusion is more difficult to pull off, as both alliances need to take some physical action to bring it about, and there would be some natural concern over whether or not the other alliance was going to follow through with their commitment. A game of chicken could ensue. Also, it seems that getting all six teams on both alliances to agree to take a physical action like this, that many would perceive as being contrary to the spirit of the game – if not the rules – would be trickier than taking no physical action, as in the option above, and simply letting the points accumulate passively.

This year we worked hard to keep the rules simple, and to keep both penalties and rules to a minimum number. I’ll give you a specific example of an approach we occasionally used. You will note there are no rules in the manual giving penalties for teams building stacks of totes more than six high. Very high stacks are still somewhat of a concern, however, as they are harder for field reset to deal with and potentially could lead to game pieces exiting the field if the stacks are tipped over. Rather than telling teams they can’t build over six totes high, and assigning a penalty to that, we simply said, per Section 3.1.2.3, that if any portion of the tote extends over the backstops on the scoring platforms, they won’t be counted as scored. In this way, teams have no incentive to build high, as it’s a waste of resources they otherwise could have turned into points. Will we still occasionally see high stacks? I think so. Some teams will have not picked up on this element in the manual, as it’s not a ‘G’ numbered rule and has no penalty assigned to it. For those teams, we think they’ll quickly get up to speed at events. The cost, though, of more aggressively working to prevent these outlying actions within the rules is a more complex manual, more nuisance penalties, and something else the refs have to watch for. We essentially were willing to keep the manual simpler in exchange for likely more often seeing stacks higher than we would like to.

We took a similar approach with the second form of collusion with the litter. We don’t know how often this would happen at actual events, and actively preventing it likely means more complicated rules. However, looking at the forums, the possibility of this noodle agreement happening at events looks as if it’s creating some concern in the community, and distracting from other strategic elements of the game. This still may not be likely to happen often at events under the current rules, but if it does, I think they will be less enjoyable.

So, in this case, we will be making some changes to the rules to discourage this activity. They won’t be perfect, but they should be an improvement. Game Design, like robot design, means working through many trade-offs. The changes are not ready for today’s update, but will follow shortly.

Frank National Instruments has alerted us that they have received reports of the power terminals on some roboRIO’s not being completely screwed in. Teams are encouraged to check the power connector’s connection to the roboRIO. The Kickoff Kit Checklist for the Separate Items has been updated with a new “Where to get more” for the Recycling Containers and Pool Noodles.
And some other updates:

Section 2 - The ARENA


Section 2.1.3 - SCORING PLATFORMS


Each SCORING PLATFORM is adjacent to a BACKSTOP and positioned such that the bottom edge of the Platform Ramp is 3 ft. 3 in. from the center of the Landmark. Please see Figure 2-5 for more details.

Section 2.1.5 - Zone Markings

T̶a̶p̶e̶d̶ ̶B̶o̶x̶e̶s̶ STAGING ZONES: Each ALLIANCE has three (3) STAGING ZONES...

Section 2.1.6 - The Landmark


Each AUTO ZONE contains one (1) Landmark, which is centered across 1̶5̶ 13 ft. 7 in. from the ALLIANCE WALL.

Section 2.3.2 - RECYCLING CONTAINERS

The lids are secured to the g̶a̶r̶b̶a̶g̶e̶ ̶c̶a̶n̶s̶ RECYCLING CONTAINERS using cable ties, and each lid has a 4.75 in. diameter hole in the center.

Section 2.3.3 - LITTER

Each LITTER is a solid core, green Pool Noodle, manufactured by Tundra (Part Number: SR20C). They are between 4 ft. 7 in. long and 4 ft. 10 11 in. in length and have an outside diameter of approximately 2.6 in. Given that the manufacturing process for Pool Noodles is not tightly controlled and the Pool Noodles used and distributed for the 2015 season were made in different production runs, teams should expect some variation in rigidity, length, diameter, and surface characteristics.

Section 3 - The Game


Section 3.2.1 - Safety

G6-1 DRIVE TEAMS may not use any object to prop the CHUTE DOOR open.

VIOLATION: RED CARD



Section 4 - The ROBOT


Section 4.2 - General ROBOT Design

R3
Size constraints specified in part B may be met with additional aids such as bungee cords, minor disassembly, etc., provided transition from/to the TRANSPORT CONFIGURATION does not risk violation of other rules, particularly G̶5̶ ̶a̶n̶d̶ ̶G̶6̶ G10 and G11.

Section 5 - The Tournament
Playoff Tournament MATCH nomemclature in Sections 5.4.4 and 5.6.3 was corrected to be consistent with nomenclature used in Figures 5-2 and 5-5.

Section 6 - The Glossary
BACKSTOP – an aluminum structure positioned between each SCORING PLATFORM and the GUARDRAILS, primarily used to determine the LEVEL of a scored RECYCLING CONTAINER.
