Re: New size/bumper rules that every team should know
This is immediately what I thought of as well. The last 4 seasons have had very different bumper and frame perimeter rules - FIRST and the GDC should highlight this subtle (but major) change as much as they can over the next 10 days or so.

Re: New size/bumper rules that every team should know
This seems to defeat the purpose of bumpers, at least how they've been used the past few years, doesn't it?
They used to guarantee about 6 inches of distance between "internal components" of robots. With this game, everything will always be inside the frame perimeter, but the grace distance that the bumpers used to provide doesn't exist. Teams will have to be careful to either build robustly, or be well inside the bumpers. Bumpers may or not actually provide any protection. This makes the real volume less than the stated volume. |

At the start of the match all parts of the robot except the bumpers must be within the frame perimeter (which does not include the bumpers) as typical in FRC. The grace distance is still there. The only things that are vulnerable are frame perimeter extensions that deploy after the match starts as usual. |

Re: New size/bumper rules that every team should know
I'm afraid there's going to be several teams unable to compete at their event because they show up with bumpers outside the sizing box and have no way of cutting 5-6" both directions. Glad I'm not the LRI that has to tell them that.

Re: New size/bumper rules that every team should know
Not sure if this is the right place but would these bumpers be legal?
http://imgur.com/aK9ofzy The gap is 13 inches but there will be a beam above the bumpers connecting the two sides so that the frame is technically all closed. edit the two shorter sides are both 6 inches. |

What is your Frame Perimeter? Read R01, particularly the blue box. Now read R22, including the blue box, and R29G. I'll explain in the spoiler, but I'd like you to read those rules first. Spoiler for The Answer:

Re: New size/bumper rules that every team should know
Yes, last year's was the highest bumper zone since our rookie year (2012), and this year is the lowest since then. Fortunately, there are no scoring platforms or defenses or anything but flat carpet to drive over.

Re: New size/bumper rules that every team should know
A frame perimeter of 23" x 25" seems tiny! Any ideas of how to make the most of vertical space?

Mounting all the large electronics vertically and grouping by power and control sections is how we freed up most of our space. RoboRio, radio, signal light, and VRM went on one side of the bot, battery, PDP, and main breaker went on the other. All were mounted on vertical boards from the chassis bottom to our top frame rails, so 7"-8" of space. |

Re: New size/bumper rules that every team should know
That was mostly because robots had to be built tall to get over obstacles. Bumper zone is a rule that changes a lot year to year.

Re: New size/bumper rules that every team should know
When I first read the rule with the green background, it made no mention of bumpers.
However upon further searching I found this: R03 Maximum ROBOT size, including BUMPERS and all extensions, must be constrained to one of two volumes: ... I'm with Blake on this issue and think it needs to be explained by FIRST as its hard to believe they really want us to build small robots with a frame perimeter of 120 inches. Dave |
