Could you point me to where this is in the manual?

They're COTS parts...

I think he means part of the 45lb withholding allowance.

He referenced that separately. COTS parts have no limit listed. (Besides the practical limit of how many you can carry into the venue and store in your pit, of course.) Yet he claims there's a 500-lb limit. I'm rather curious to see where that number comes from.

*Thinks about it*
How many rivets can stuff in my Kia Soul...

But yeah I have not heard of the 500lb limit and I can't find my "Citation Needed" sign on a stick...
Is this new?
I should really find where that stick is...

If the mechanism is assembled together, the bolts that hold it together are included in the weight. The bolts move from the definition of COTS to being included in the definition of FABRICATED ITEM since they are in an assembled state. The same thing goes with motors, pneumatic cyllinders, servos, etc. Keep that in mind if you're close on weight.

There was a Q&A on this in 2012 I think.

So, I heard that Practice matches were on Wednesday this year. Can anyone verify this? That would mean that the time we have in the pits to make modifications would be like...30 minutes after Load-In.

2 hours for load-in/work with 5 team members, 3.5 hours with full team (practice matches and inspection).

Mr. V and JesseK are correct. If the part has been assembled in any way, it is considered fabricated and counts to the 45 pounds. Including fabricated spares.

There is no practice on Wednesday. The goal is to have all 215 robots passed inspection by 8:00 pm on Wednesday so they can all practice first thing on Thursday.

Championship is different this year. See the Agenda that Max posted.

I didn't see that a few days ago. Interesting.

FYI: You can practice in your scheduled slot without passing inspection. But, to cue up for open slots, your bot needs to have passed inspection. - This is for regionals, but have no reason to believe it would still not apply for championship, especially since practices start 30 minutes after pit open.

It was also posted on Frank's blog in Jan. You gotta run fast to keep up with that guy.

Wow, what year is that information from? I don't have counts of teams attending the Championship from before 2003, when there were 291.

Wednesday practice is a thing.

Once a COTS part is assembled with other COTS or fabricated parts it becomes a fabricated assembly. So if there are motors, or actuators on the new ball grabber then the entire weight must be under 45lbs. If on the other hand you remove the motors or actuators that are already on your robot as put in the bag then you may transfer them and that would not count as part of your 45 lbs. Also if you brought those motors, actuators or hardware in the manner that they are purchased then they are not fabricated parts, do not count as part of your 45lbs and you may instal them at CMP.
