Newb question: weight limit

[R22]
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.

Found it.

If you take a part you get "off the shelf" and drill a hole in it(or bend it, break it, light it on fire, etc.), it magically becomes a "Fabricated Item".

... and Fabricated Items count towards.

[R26]
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.
