Things happen, and the only pch we have fell and broke. i’m sure that it will still turn on and power the system fine but i dont think this will be allowed at a competetion due to it being a potential safety hazard. Is there anything I could do to modify it to change that?

You will have to acquire a new one or use a ctre one

That doesn’t meet R710.

I’m very curious how this happened… how high did it fall from?

It was on some…unstable grounding (wheelie table). It was connected to a pnuematics system and somebody knocked the compressor down and everything just fell suit. (it was like 4ft off the ground too…)

While saying no more PDHs were available to purchase, there was mention of some reserve to meet needs for things like replacement, so you should definitely contact and see if REV would be able to help you out, even if that means to buy from their reserve pile.

I see an email to [email protected] in your near future.

Seems like a huge failure for just a drop off a table. Kinda wild.
Looks like a robot drove over it multiple times.
We had one break as well, but much less extravagantly

Yeah, it was very overdramatic

I guess I can’t say definitively, but as long as there isn’t a breaker in that spot, there shouldn’t be any issues in regards to shorts or anything. You’ll definitely be better off RMAing it if that’s an option though.
R710 appears to only refer to intentional modifications. Fielding a broken control system component should be fine under that rule as long as the rest of the robot rules are met. If it doesn’t meet R710, then it can be made legal by “repairing” it to fulfill R710.M.

Side note, I would highly suggest you don’t use components you have no spares of. If this happens at a competition, you will probably have a very hard time finding a replacement.

R710 does not address rather or not the modification is intentional just that it was made.
710M requires the repaired component meets the original specification. That would be a discussion you will be having with the LRI. I would suggest having a plan B.
If Rev is willing I would send it to them to fix or at the very least follow their instruction to a T. And have the supporting documents from REV for your conversation with your LRI.
@Wing Can you please reach out to us at [email protected] During our development of this we did many different drop tests and didn’t see failures with this degree of damage. I would like to understand more of the circumstance behind this failure.
As you suspected, I would not recommend using this device any more because it is unknown what internal damage might have occurred.
If you reach out to us, we can talk about how to help your team. I do want to note that this won’t be covered under our manufacturer warranty as it is due to damage and not a defect, but we also want to make sure teams have the ability to compete.

R609 says we can use the older PDP (the black, red, and green one), we are. You’re not a rookie team, do you have a spare one? Or swap the damaged one (does it work? Not smoke?) into an older bot IF IT WORKS and use its in the new bot. Throw a bunch of electrical tape on the broken part.
If your damaged PDH is powered and shorts, it’ll be protected only by the 120A main breaker/switch. You’re going to see a lot of smoke first.

I’m definitely willing to share more about the failure, its just as bizzare to you as it is to me.
We definitely have PDP’s available and thats what we’re going to use now but it was just unfortunate that our new pdh already got damaged. I wanted to see if there was a fix.
None of the electronic equipment that I have worked on over the last 40 years would be repaired if it was damaged like that. It would just be replaced. It is quite likely that there are broken traces on the PCB and that the bonds between the traces on the PCB and the plate through holes are likely to be broken in places. Repairing damaged PCB rarely gives satisfactory results and would only be attempted in cases where no replacements are available i.e. antique equipment.
