COTs part's question

[yash101]

There are some small computers like the Intel NUC. It would be classified as COTS unmodified. However, it is barebones and comes with no disk drives or RAM. That means you need to "modify" it by adding so-dimms and an mSATA ssd. Would this still be considered a COTS part?

[SenorZ]

No. It is no longer COTS if someone cannot buy it, in that configuration, in a store, or online.

A COTS part that has been painted is considered "fabricated" because it is not available in that "configuration" to the general public. A COTS controller board, memory card, etc., are all COTS on their own. But once you slap them together they become a "fabricated" item.

[Doc Wu]

Or do they become a collection of COTS parts? Can't anyone buy the HD and memory off the shelf?

These seems like it would be something that could be easily clarified by the Q&A when it opens on the 8th.

[yash101]

It can be taken either way. The device was meant to be expanded. I doubt that you'd use a computer without RAM and a Boot drive! This is something kind of complicated and maybe Al could clarify this for us because he is part of the inspection team.

We aren't building the RAM modules ourselves, neither the disk drive, so we are technically not modifying the computer. Just pull out the ram, wifi, bt and disk and the computer will be exactly as out of the box.

By the way, how much could I get a CHEAP set of 4GB RAM that will work? This wouldn't require anything special. The same would go for the SSD. This isn't something we will be using daily, so a cheap ssd will most likely cut it. Otherwise, maybe I could boot from a flash disk!

The components would all be considered COTs. The issue is how to power it. You either will need to power it from the robot battery or the battery will need to be self contained in the COTS computer.

[yash101]

I was thinking of a 12v to 19v boost converter. I think it would be cots legal because it is external. It is just a vReg, so I am doubtful that any problems would be caused!

[DonRotolo]

Definitely a Q&A question.
Also, I think the CUSTOM CIRCUIT of a 12 - 19 V converter wouldn't be a problem.

In the past we fielded a Gateway netbook with added RAM.

The RAM modules are COTS. The Gateway netbook is COTS.

The COTS rules should also not prohibit repaired systems but I've not actually competition inspected a repaired laptop on a robot and I am very unclear on how anyone would know. I've repaired plenty of driver's station laptops that were used in competition.

We did remove the display and keyboard from that Gateway netbook we had on the robot and it was like that during inspection. You can't buy it COTS without the display and keyboard but through several inspections no one complained because it was properly enclosed and packed in foam blocks.

I have seen cRIOs that were repaired fielded.

Nothing stops FIRST from changing this around but we actually did this so it would be a change.

Isn't that illegal? That involves opening the case of the cRIO!

Think for a minute - how would you know?
What do think National Instruments does when they refurbish these things?

The issues of how do you detect tampering was part of the reason why when I helped to propose a 2015 control system I proposed a tool that would detect tampering and the altered operation. A proper repair does not alter the normal operation it restores it.
