We Built a Free Kit Parts Finder for Every FGC 2026 Team

Here's a problem every FIRST Global team knows.

You're in the workshop. You're looking at a drawing. It says "15mm Plastic Lap Corner Bracket." You look at the big pile of bags and bins in front of you. Which one is it? What does it look like? How many do we even have? And is it the same thing as the "inside corner bracket" Paul is holding?

Now imagine that, but in English, when English is your second language. And with a kit that has no spare parts, where using the wrong piece can mean a cut you can't undo.

That was us at the start of the season. So we built a tool to fix it. And then we decided to share it with everyone.

FGC 2026 Kit Parts — by Team Benin: femcoders.com/tools/revkitfgc/

What It Is

It's a free, searchable catalogue of the official FIRST Global Challenge 2026 kit. All 152 components, each one with:

• a photo, so you know exactly what you're looking for,
• a simple, plain-language name ("90 mm omni wheel — pack of 2", not a wall of codes),
• its official REV part number (like REV-41-1190-PK2), so you can match it with the official parts list,
• its category,
• a reference number from #001 to #152.

Quantities follow the official bill of materials. (One honest note, also written on the tool: for some packs, the exact contents aren't detailed.)

And it works in English and French. One tap on the language button and the whole catalogue switches.

Nine Categories

The 152 parts are sorted into nine categories, so you can browse instead of scrolling forever:

• Storage — 1
• Game elements — 3
• Control & sensors — 12
• Cables — 13
• Motors & servos — 9
• Motion — 53
• Bearings & hardware — 23
• Brackets — 26
• Structure — 12

Fun fact: Motion is by far the biggest family, with 53 parts. Gears, sprockets, chain, pulleys, belts, hex shafts, hubs, spacers, and all the wheels. If you've ever lost 20 minutes looking for the right spacer, now you know why.

How To Use It

Type a word in the search bar and the list filters instantly. You can also tap a category to see just that family. If nothing matches, the tool tells you to try another word.

Some searches we used ourselves this season:

"flap" — shows the flap wheels: the 4-inch hard flap wheel (REV-41-2703-PK4) and the medium flap wheel (REV-41-2702-PK4). Our intake and our feeder are built from flap shafts, so we searched this one a lot.

"cone" — shows the two cone wheels, 2 to 3 inches, MAXSpline: medium (REV-21-6564) and hard (REV-21-6550). Two cone-shaped wheels facing each other make a V. That's exactly the shape of our climbing roller on the Brace.

"omni" — the 90 mm omni wheels (REV-41-1190-PK2), at the corners of our drivetrain.

"hub" — Control Hub (REV-31-1595), Expansion Hub (REV-31-1153), Driver Hub (REV-31-1596)... and the mechanical hubs too.

"chain" — #25 roller chain, master links, the chain tool. Our intake's three shafts are linked by a chain.

"400" — the 5 mm × 400 mm hex shafts. Long shafts are the backbone of wide mechanisms like a full-width intake or flywheel.

You can also search by REV part number if you have it from a drawing or the official list. Paste "REV-41-1600" and you get the HD Hex Motor with UltraPlanetary gearbox.

Why We Made It

There were three reasons.

1. "Name every part" needs a dictionary.

Our method starts with drawing, and on every drawing we write the exact name of each kit part. That's how we check we have enough parts before cutting anything. But to name a part, you have to recognise it first. The tool became our dictionary: photo, name, number.

1. Not everyone on our team reads technical English.

Our team goes from 7 to 18 years old, and French is the main language at home and at school in Bénin. Technical English like "15mm Metal Offset Servo Bracket V2" is a lot. In French, the tool says "Support métallique décalé pour servomoteur". Suddenly the younger members could find parts on their own, without asking an older member every five minutes. That made the whole team faster.

1. Many FGC teams are in the same situation.

FIRST Global brings together teams from many countries, and many of them work in a second or third language. Every team gets the same kit. It made no sense to keep this to ourselves. If it helps one team in Africa, Latin America, Asia or anywhere else find a part faster, it's worth it.

What We Learned Building It

Making the catalogue made us better engineers, honestly. To write a simple name for each of the 152 parts, we had to understand what each part does. What's the difference between a "through bore bearing — short" and "long"? Why are there plastic brackets at 30°, 45°, 60°, 90°, 120°, 135° and 150°? What's a tensioning bushing for?

By the end, we knew our kit much better. And knowing your kit is half the battle when there are no spare parts.

It also taught us to be precise with words, which is the same skill as being precise with millimetres. A vague name ("small wheel") leads to the wrong part. A precise name ("1-inch grip wheel, 5 mm hex bore, soft, pack of 4") leads to the right one.

IT'S YOURS

The tool is free. No account, no download, no ads. It works on a phone, which matters a lot in a busy pit at the competition, when your laptop is buried under a robot.

Use it in your workshop. Use it in the pit in Incheon. Share it with your rookies, your mentors, your friends on other teams. If you spot a mistake or a better name for a part, come tell us at our stand, or send us a message. We'll fix it.

Find us in Incheon. Ask us anything about the kit. 🇧🇯

Takeaway For Other Teams

Make tools for yourselves, then share them. The thing that saves your team 10 minutes a day probably saves another team 10 minutes too. FIRST is about building robots, but it's also about building each other up.
