I’ve been tasked with helping our LVRPC identify spare parts items that would be most helpful at an event. The pickings are pretty slim by the time week 5 rolls around and we may be able to acquire parts to be made available next year at our regional. Any suggestions? Thanks in advance for any help rendered.

Find out the sizes of all the screws on the REV Swerve Drive. Get those.

All of the major modules, especially RIOs. They’re pricey, but it seems like 1-3 of them end up fried every event.
Main breakers also come to mind as problematic components that few teams keep spares of.
Having a set of loaner chargers can be very helpful for rookie/young teams that don’t realize how much their 12.4V batteries are impacting matches.

Do the fields travel start the season with an itemized spare parts list? All the missing stuff is probably the useful stuff.
As a week 1 abuser of spare parts access. It’s basically “stuff you could have got from first choice but not Home Depot”.
Rio, vrm, pcm, any brushed speed controller, signal light, radio, maybe a few of the smokable motors, rolls of red and blue fabric.
If a team has an exotic parts budget it’s on them to plan their own spare parts.

Definitely USB A cables, robo rios, vrms, batteries, wiring multiple gauges, Anderson power poles, essentially everything in the pneumatics system outside of a compressor probably not needed. I feel like I pull those for teams the most, there’s definitely always random things like RSLs breaking or teams buying the wrong andymark RSL

Things teams need that aren’t listed already.
An organized bolt and nut case for 10-32 and 1/4-20 hardware.
Bumper plywood, noodles, and fabric. (Add some L brackets for making mounts)
1/2" hex shaft collars, bearings, hubs, etc.
Wago 221 inline connectors (good for motors), and other smaller lever nuts (good for sensors and can)
Can wire (twisted pair, yellow and green), 12awg wire, 18 awg wire, pwm cables, Ethernet cables
Any parts common to the everybot.

This may not be essential depending on who you talk to but having a spare long ethernet cable on hand can’t hurt if that memo is missed by a team. I know we replaced ours mid-competition at Greenwood this season. That being said it may be a spare part that experiences more wear and tear so I’m not sure how much longevity factors into what you’re looking at.

THIS.
Every event I was at this year had 3 or more Everybots. If every event had some of the common parts available that would have made helping teams get their Everybots scoring so much easier.

Also numbers, whether they’re iron on or just white paint that can be used. I heard many teams at each event looking for materials to fix their numbers.

The 10 A ATM (red mini-blade, like these) fuses for the Rev PDH, as required by R615-B and R617-B. Many teams were overlooking this, and needed to install some; spare parts ran out of the few that they had.
The longer-term solution to this might be for FIRST to decide whether or not it is essential to require this fuse value in the future.

Pressure relief valves per R804-B and its blue box. Preferably ones that have been reliably factory-calibrated to release at 125 lb/in2.
These are unfortunately fairly expensive, and there are some weird failure modes where the valve is technically within specifications but continuously leaks slowly at full pressure. Finding a cheap, reliable one would be beneficial.

I’ll add on something I had to use a few times that wasn’t in spare parts: roborio power connectors.
Sanity and patience.
From my years at comps, I’ve seen at least 3 of my team’s intakes get smashed in some way, so we always bring spares so we can repair it if anything goes wrong. good rule of thumb is if it sticks out of the robot, you should have a spare
Rev PDH fuses. Few teams needed pdh fuses at bosphorus regional but couldn’t find. As a result one team needed to remove their whole mechanism. I guess PDP fuses are more common and can be found easier. Also pcm and vrms. We had our pcm broke before match and if spare parts didn’t have pcm we would be doomed.
You can legally use the PDP fuses (20 and 30 amp) on the PDH.
40 amp ones were the ones teams needed. But good to know 20 and 30 amp ones are usable.
