Low weight we can bring to the event

[nitneylion452]

Teams may bring a maximum of 30 pounds of custom FABRICATED ITEMS (SPARE
PARTS, REPLACEMENT PARTS, and UPGRADE PARTS, plus all WITHHOLDING
ALLOWANCE items) to each competition event to be used to repair and/or upgrade their ROBOT at the competition site. All other FABRICATED ITEMS to be used on the ROBOT during the competition shall arrive at the competition venue packed in the shipping crate or lockout bag with the ROBOT

REPLACEMENT PARTS – a COMPONENT or MECHANISM constructed as a functional duplicate of an existing part of the ROBOT, for the purpose of replacing a broken or defective part.

UPGRADE PARTS - a COMPONENT or MECHANISM intended to provide additional functionality not currently available on the ROBOT. UPGRADE PARTS may be COTS items or custom FABRICATED ITEMS, and may either add to or replace existing functionality.

Blue Box:

Example: A HOSTBOT is designed with a c-channel frame. The system works well, but can be misshapen if hit aggressively. The team adds two more pieces of cchannel to brace the frame and prevent this problem. The c-channel is identical to that already on the HOSTBOT. The new pieces of c-channel would be considered UPGRADE PARTS even though they are the same as the ones already in place, as they alter the functionality of the HOSTBOT and provide new capability

It seems like what you start with is what you have to stay with for the most part. I take this to mean that you can't build an entirely new mechanism.
