Trackballs

To those who were around during the 2004 game:

Do the balls from this year behave in a similar way to the 2004 balls?

Less bouncy with 2 layers of different materials acting as a damper, more heavy as well because of that fact.

This is going by memory.
No "official" tests were done by myself to conclude this other than some common sense & interactions with both 3 years apart. lol

pretty sure that the opposing team would get points for you knocking down ball or nobody

Does anyone have a "disclosable" source for those balls.

They are similar. The 2004 (and 2001) era balls were 30", and comparable to what we would call the bladder of the trackball.

Elgin, it's been four years since FIRST Frenzy.

Yup we need one. I sort of, errr, ruptured ours last night while working.

I think it's time to return to slightly smaller field elements- last years rack couldn't be built anywhere due to space restrictions, and these balls are larger than the standard width of an aisleway! (30" according to ADA).

And they cut very easily if you bounce them into a metal table. Sigh.

I called FIRST yesterday and they said they'd release information on buying more either today or tomorrow.

Does anyone know where we can order more track balls?

Update 3 does ...

[chinckley]

Does anyone know the PSI of the trackballs?
I see in update 4 that they weigh about 7.3 pounds, but
one of our mentors wanted to know the PSI.

PSI doesn't matter. Check Q&A and they'll tell you the same thing. It's the size that matters. I suppose if you really want to know the PSI, you could inflate one to the right size using a pump with a gauge on it and check that.

Do you know what they are using to tell the size?
How do we know when it is inflated correctly?

I don't know what they are using. I would suspect some sort of box, but it may also be "does it look right?" You could ask Q&A--I haven't seen that question yet.

I do not understand this from Q&A...


Touching the rack while hurtling

----------------------------------------------------------------------

Are there any limitations on touching or hitting the rack while hurtling?



Re: Touching the rack while hurtling

--------------------------------------------------------------------------
Restrictions on contact between the Robot and the Overpass are defined in Rule <G34>.

Restrictions on contact between the Robot and The Rack are much more severe, as they would have to involve reverse time travel.

What does this mean?
