weight withholding allowance question

[slijin]

A Commercial, Off-The-Shelf (COTS) item is defined as a part in its unaltered, unmodified state. A COTS item is a standard (i.e. not custom order) part that is or at one time been commonly available from a Vendor. Once a COTS item is modified in any way, it becomes a Fabricated Item.

Unless the Vendor only provides or sells customer-requested lengths (in which case this question should be posed in a Q&A), it is considered custom; that is, if the Vendor offers any standard lengths or sizes for the object in question and you order a size that is not one of those, it is considered custom.

This is a modification, which therefore makes it a custom part.

No, you may not.

See my first response.

The latter.

[RRLedford]

So, in order to bring in the maximum "under 30 lbs" worth of stuff considered to be customized assemblies, we are looking at stripping out most of their easily removable COTS component items that have previously been integrated into these customized assemblies, and then reassembling them in the the pits.
Is this considered an acceptable strategy within the rules?

Dick,

Teams may bring a maximum of 30 lbs of Fabricated Items to each competition event to be used to repair and/or upgrade their Robot at the competition site. The Operator Console and any battery assemblies (see[R03]-A) are not applicable.

That would suggest that COTS items removed from fabricated parts are not included in the 30lbs. However, if you modified any of the COTS items, i.e. machining on the shaft of a CIM, then that part is no longer a COTS item.

So using this logic;
[devil's advocate mode]
Batteries with the wires cut to length, Anderson connecters crimped or soldered count in the weight allowance? Is it specifically exempted?

Motors with the leads attached?

Andymark gear boxes that have been assembled from the as delivered condition?

Banebot gear boxes that have been disassembled, greased, & reassembled?

Raw stock that has been cut from the as delivered condition so that it will fit in the pit? It seems like previous years rules specially allowed this. Lost in the simplification?

Batteries are explicitly expemted in the rules.

Banebots that have been greased but do not have motors assembled is something everyone seems to be letting go but I'm not sure of the official ruling. If the motors are assembled they are no longer COTS.

AM gearboxes that are assembled and not as delivered are no longer COTS as they have been assembled. This is equivalent to carrying in an assembled kitbot and saying it is COTS. Once you put that sweat equity in it is no longer a COTS part.

Raw material that is just cut for handling purposes is fine, however if your handling length is exactly what you need to make a part you designed for pit fab we both know you're lying.

This is an honor system and there are many of us that go to extraordinary measures to comply the rules, so if some one thinks they see something fishy be prepared to answer their questions.
