Dang, I can't believe I missed that lol. Does it seem like it's not bolted perpendicularly? Can't tell from the pic... EDIT: Well the bars and the top of the bent piece of the bracket are parallel, so that means they're perpendicular... |

Never mind, I can't upload my image - too big of a file

Re: [BB] 2010 Game Hint #1
It looks like a support for parallel bars (rails) that balls could roll on. The shallow slope (see below) would require a low rolling coefficient of friction in order to be gravity driven. It would require a ball of a particular size that was quite hard and smooth. Something similar to a moon rock or even the 2006 foam ball wouldn't roll on something this shallow. It would take something like a basketball or (I shudder to think!!) a bowling ball.
Quarter-inch lexan would be tough enough to handle the sort of contact you get in an overhead structure. It doesn't appear strong enough to take the impact of a 120 lb robot at full speed. BUT - This is too easy. I doubt the GDC would release a clue that identified the size, shape, and "texture" of the game piece. I suspect trickery! It may be a field element, but I doubt that it is for moving the game piece (directly). How much clearance is there between the "top" of the tube (as shown on FIRST) and the underside of the lexan bracket? If the rails held some sort of cart (like a car on a roller coaster with tubular rails), would there be enough space for some sort of "keeper" (something that would keep the cart from getting knocked off the rails) to pass between the tube and the bracket? Why else would the rails be held from the outside and not at the point nearest the tab on the bracket? Note regarding the slope: Look at the radius of the bend in the "lexan" bracket. It isn't uniform - it forms a conical shape that is wider at the bottom. |
Re: [BB] 2010 Game Hint #1
I've been studying the picture, and I'm not sure if anyone has said this, so i apologize if you have. To make my point more clear, I'll put a picture below.
FIRST has been trying to cut back on costs. So realizing that, Lexan, as previously mentioned, is expensive. FIRST wouldn't cut back on costs, and spend money on tons of lexan for rail supports for 32+ fields. In my opinion, that lexan part is merely a mount for a counter sensor. It'll detect some ball or round object. In the middle of the poles, there are holes, larger than necessary, for a screw head to go through and not to interfere with any game element rolling down it. On the pole, towards the top, there is a hole identical to that. It doesn't appear to be a reflection or refraction from anything BUT that pole the lexan is mounted to. You can see the pins from that pole too. The only issue is that hole does NOT appear on the front most pole visible to us. My hypothesis is it's a mounting hole. As i said the lexan is merely a strong support for a sensor (because the software guys on my team HATE it when weak mounts break and they lose a sensor). This rail system will be mounted on the outside of the field. Somewhere. and this is just some junction to count the scored balls. Longer poles, curved poles, whatever, will connect to this. But that single hole makes me believe its mounting somewhere on the outside, or even the inside, of the field. But on the side of something. ![]() Thoughts or comments on this?? |

Which is why there seems to be reflection of the ridge where the larger tube ends. If it isn't the reflection, then the larger tube looks too long. |

Re: [BB] 2010 Game Hint #1
I highlighted the reflections to make it easier to talk about.
Red & Magenta: Reflection off the tubes and off each other (Yes, it works out. see this post http://www.chiefdelphi.com/forums/sh...9&postcount=77) What is the orange outlined shape? ![]() |
Re: [BB] 2010 Game Hint #1
one question could be why the GDC waited until today to release the hint?
Just saying, sticking with the moon theme from last year, today in 1968, the Apollo 8 first entered orbit around the moon... orbit around the moon = balls traveling around a track? I doubt it... |

Re: [BB] 2010 Game Hint #1
I showed it to my very much non-engineer parents and they both immediately thought it was a bracket for a 2X4 or something. Maybe it's Robot Limbo!
