Re: [BB] 2010 Game Hint #1

It's Christmas eve. I'm sick. Why, GDC, do you have such pinpoint timing?

Well, frankly I wouldn't rule out it being a game-piece. If it doesn't seem sturdy enough, remember last year's orbit balls? Yeah, not the sturdiest of tools.

In any case, I like the idea of this being the goal somehow, vertically standing, and changing height. Perhaps this has something to do with human player interaction? Because I don't think that we could really design an effective robot to press those damned side-buttons in! Those things are DEATH.

Inevitably, I have no idea.

Happy Christmas.

EDIT: Oh, and I forgot to mention. What if a bunch of these little buggers attach to each other via the pipes?

Re: [BB] 2010 Game Hint #1

I spent a few minutes trying to recreate this in Inventor. I completely guessed on a lot of the stuff, so it looks different from the original model, but I think the CAD renders will display some things. I apologize if my post seems huge because of the picture size

First off, we have the original. Now my problem was that no matter what, i could not create this reflection circled in red. As you can see, this must be another part that corresponds with this. A pole with pins in it.



Here is the model I tried to replicate. Same background with the reflection, same material.



I flipped the render. I was too lazy to get the background perfect, but everyone who was talking about a track, I'm sure this is what your imagining

Re: [BB] 2010 Game Hint #1

While I still think that this is a field element, if it IS a robot piece...my vote goes to battery mount. Doesn't it just look like a battery would fit in there nicely?

Though the reason that I don't think that it's a robot part is because of the pins/bolts/?? at the ends of the two tubes. No matter where this assembly would attach, it would be VERY constricting in terms of robot design. I understand that the rover wheels last year changed drive trains a lot, but most teams were able to simply modify whatever they had previously used to encompass a differently sized wheel. If this part is to scale by Inventor standards, it seems like it would HIGHLY constrict robot design - even if you found a different way to attach it to your robot/were allowed to do so.
I'm not trying to shut down any ideas; just my $0.02

Re: [BB] 2010 Game Hint #1

I'm just gonna throw this out there. But I don't think focusing on the reflection is going to do us any good. There is going to obviously be other stuff on the field besides this part.

Cool. Try making the inside to inside of the lexan 7.75" apart, the large tube 1.5" in dia, and the small tube 1.25" in dia.

Assuming 0.25" thick lexan.

I'm still trying to find out the radius of that curve cutout.

Re: [BB] 2010 Game Hint #1

Maybe it's just a part of the new entrance gate to the field. No? Then what if you turn the object vertical and mount a few of them on the end wall,a few feet into the field,making the lexan the stationary part. This would make the poles the moving part,with set distance of travel due to the stop pins. I think those are stop pins because i have never seen back to back push pins. It could be put at a height that the top pin would stop, what i will call a wall, from falling all the way to the floor. This gap at the floor is so your bot can slide the wall up and push the game piece into the scoring area.

Re: [BB] 2010 Game Hint #1

The only thing I can gather from this, is that whatever this piece is, it's apart of the field, and it's not laying on the ground. It has to be some part of a larger mechanism, something like The Rack, only this is a lot more interesting.

Re: [BB] 2010 Game Hint #1

The pins could be like those on some tent poles. Press them in and slide the pole till they snap into the holes on the outer tube. This would allow the inner pole to lock in either of the holes.

Re: [BB] 2010 Game Hint #1

I'm going to echo what others have said in terms of it doesn't seem to be strong enough to withstand direct robot interaction. this could very well be a part of the Human Player interaction but I just don't see it being part of a scoring structure that will need to withstand the abuse of a match/competition.

In any event, Welcome tot he 2010 FIRST Robotics Competition

If your a rookie, don't lose sleep over this hint, but have fun with it.

Happy Holidays everyone! Enjoy spending time with your family because 16 days from now you will see them very little over the following 6 weeks.

Re: [BB] 2010 Game Hint #1

I see one odd problem with the adjustability...The little nubs that go into the yellow piece...Well, they don't go all the way through. If you were to push them in to adjust it, they would just like...fall into the tube. Also, if you were to move the thing, the nubs don't like, match up. Imagine the middle part being moved up to lock in place... only one of the holes would have the little pin in it. Why make two holes in the middle then? Another thing - because the little nubs or whatever holding the yellow part on don't go through...they could be either hollow, which WOULD allow for adjustment...somewhat...or, the middle tube and them are all one solid piece, but then how does the yellow part snap on...THE FACT THAT THE PINS DON'T GO ALL THE WAY THROUGH SCREWS EVERYTHING UP.

Another thought - The nubs on the ends are for attachment of other pieces. Ergo, the thing is NOT adjustable.

Also - What about the 4 other holes in the yellow part?

Idea explaining end pins - more tubes attach to the bottom and top, making some weird abomination of mechanical engineering, aka an obstacle or something of some sort.

Re: [BB] 2010 Game Hint #1

Hey guys,

Look, yes FIRST is known for its trickery and hints, but maybe we have not looked at it fully. Try turning the picture 90 degrees. It looks like a holder for a game piece that could easily be mounted on the side of the field. I mean yes it is a little farther out. But I looked and thought it would be a trailer hitch again. With how it looked and where you can just roll up to a trailer, hook on, move it around and even dump w.e it is inside the trailer somewhere else. But with the look out of it. I see a high game piece, maybe even an extra bonus piece being placed up there. Or, even the last second bonus area to score. Maybe finally seeing some square game pieces like the Wall of totes in 2001.

I'll work on that. I was very close. The inside to inside of the lexan was 8". the large tube diameter was 1.5", and i kept the wall thickness at 0.83" which is what FIRST used is the past for field elements made out of steel. Especially the Overpass. The small tube is 1.417" in diameter only because I just made it off of the inner diameter of the large pipe. Same wall thickness.

I can't remember the radius of the cutout, but I believe it was 11"

Re: [BB] 2010 Game Hint #1

Top 100!!!

Sorry I had to before this tread becomes 900 posts long,
It looks like Christmas really did come early this year.

As far as the part goes I question a few things that I don't think we can quite make out.

1. Do the spring pins depress are are they fixed.
2. If fixed do the pipes that they are on rotate around the center object so something can "screw" onto it to lock it (or the robot for that matter) in position.
3. I have worked with with this type of "locking mechanisms" in both applications, and both have different advantages and disadvantages.

Ok on a final note my grandparents just flew into town and for kicks I had to ask...."Grama and Grampa what do you think this is?" They said it looked like the "Spaceship Branson is flying people into space with" I have to say they are sorta close.

Re: [BB] 2010 Game Hint #1

Assuming it's a ball track, here is a picture showing the relative size of things (from what I could gather from the picture), and the possible size of the ball.

Note that the 8.25" width of the lexan is from outside to outside.

Sorry for the messy dimensioning. I did this quickly.

Makes me think this is a projectile device of some type. I liked 2006. Maybe we'll have another year of balls flying around.
