Re: <R11> Dimension wrong?
We hosted a 23 team FLL tournament this weekend (it was the only date we could get a venue) and everyone (and more importantly I) was pretty beat by Saturday evening. (I was setting up the kick-off course on Saturday morning early so I was gone pretty much from 6:30 to 7:30.) So we gave the kids time off until our meeting this evening. Now I have to wonder tonight whether we should really have two design tracks, one for the 60" and one for the 213.4 cm dimensions?
The design implications are pretty significant depending on which rule is correct. If it is 60", I think it makes mecanum and swerve drive much more likely, because there will not be a lot of room to use reach to get tubes onto racks. If it is 213.4 cm then more designs are possible. |

Re: <R11> Dimension wrong?
Because the front bumper is in the way of your mechanism, it effectively counts (while the back bumper does not)

In 2007 - the last tube game, the bumper requirements were different. |

Re: <R11> Dimension wrong?
These limitations also affect your thinking about how big the drive base should be. If you go for a smaller base, you'll get more room to extend your manipulator. No wonder they say the minibot cannot go after the game pieces.
Mini, mini, Mini, go fetch! |

Re: <R11> Dimension wrong?
Minibot deployment mechanisms could be built to help get a little more room out of this restriction because the minibot itself (The portion that detaches from the hostbot) is not considered in volume limitations.

Re: <R11> Dimension wrong?
By my reading, the MINIBOT is not even included in the STARTING CONFIGURATION. Wow.

Re: <R11> Dimension wrong?
Cool, all my team has to do is Velcro a minibot to a swing-out PVC stick. A drawer-like design reaches less far because of the circle.

Re: <R11> Dimension wrong?
Well I hope that the official answer comes quick.
Hard to come up with potential designs at this point, but my guess is that they will stick with the 60" rule. ![]() |

Re: <R11> Dimension wrong?
Could you tell me the rule which specifies the bumper zone this year? I haven't been able to find this dimension in "The Robot Rev -" or "The Game Rev -" Thanks

Re: <R11> Dimension wrong?
Mc,
The dimension is in the definitions for Bumper Zone. I have asked to include it in the bumper rules in the future. |

Re: <R11> Dimension wrong?
Um, thanks to all for showing me that square robots don't (easily) fit into round holes. While this doesn't prevent an arm, it certainly adds to the challenge of using one.
Deploying minibots won't be as much of an issue: If I have an 8" square minibot, I have about 3" between the edge of the minibot and the pole (assuming minibot is centered on the 1.75" pole). 18+3=21, I only need 15-3=12. Maybe a 24" stroke pneumatic piston to whack the minibot onto the pole.... Inspection: I propose that we supply 60" I.D. right cylinders of infinite height to each venue for inspection. OK, even 30 feet tall would be impressive... ![]() |

Re: <R11> Dimension wrong?
Absolutely agree, this is causing our team to branch into 2 separate design pathways waiting to hear an update from FIRST. I do hope that they stick with the metric rule for this :/

Re: <R11> Dimension wrong?
The rule gives you two possible diameters that your robot must stay within, 60" or 213.4 cm. I know which one we're using.
Seriously, I have a strong hunch the correction will turn out to be 84". Looking at the table, it is easy to imagine how the 60" could have been a typo, mixed up with the 60" in the starting height box. How likely is it that you would accidentally pull the number 213.4 out of the air as a typo? |
