Mga robot na pwedeng gawinRobots you can actually build

Libre lahat ng ito. Nakasulat kung ano ang pwede at hindi pwede. The 150 g combat robots the club prints. Every one was opened and read before it went on this list, so anything here is cleared to build. Found something else you want to make? Bring it and we will look at it together.

Mga robotThe robots

Labinlimang robot, labinlimang paraan ng paglaban. Fifteen builds and, between them, nearly every weapon there is: a plow, wedgelets, a wedge, flippers, a lifter, a grabber, a crusher, a pusher-hammer, a beater bar, a full bar, a drum, a toothed disc, and spinners that turn flat or upright. Pick one.

Adelaide Robot Combat — lifter

Adelaide Robot Combat · MakerWorld

CC BY-SA150 g

A lifter kit — gets underneath and picks the other robot up.

The cleanest licence of any robot here: no NonCommercial clause at all. Only ShareAlike, which bites only if we publish our own version.

Vertical Spinner

TheBlackfish · MakerWorld

CC BY-NC-SA150 g

The companion to the Beater Bar from the same designer — same body, a vertical spinning weapon instead of a horizontal bar.

Two weapons on one familiar chassis is the cheapest way to give a class a real choice without a second set of parts.

150g Combat Robot

MakerWorld

CC BY-NC-SA150 g

A plain 150 g build with no gimmick.

⬜ Not read in as much depth as the others — check its parts list against ours before committing a class to it.

Shredder

drcameron · Thingiverse

CC BY150 g

Two weapons on one body — a toothed disc and a bar — plus an internal firewall protecting the electronics.

The reason to look at this one first: it has built-in N20 motor mounts. The motors slide in and hold — no screws. That is the single fiddliest step on a small robot, designed out.

N20 Fairy Flipper

JairEmia · Thingiverse

CC BY150 g~$50

Rotary flipper on 2× N20s — the arms go all the way round while the button is held. Parts list and build notes come with the download. And it is a cat.

Built deliberately as a loaner bot: the designer wanted something he could hand a beginner to practise with, so the build includes its own transmitter and receiver. That is our controller problem, already solved by someone else.

Big Flip

SiegelRacing · Thingiverse

CC BY150 g

A servo flipper with a stretched chassis, and 4-inch-cube legal.

Why it was stretched, in the designer's words: they had been "hacking the big servos to get them to fit and gluing them in." This version makes the servos easy to install and swap — which matters a great deal when twenty children are doing it.

Blockhead

earthwormjim · Thingiverse

CC BY150 g★ .f3d parametric

Chassis and weapon together, with a wide front wedge and a lifting arm. There is a test video on the design page.

⭐ The best file on this whole page. It ships .f3d — Fusion 360's own format, carrying the full design history. Open it and you get the real sketches and dimensions, so changing a number rebuilds the model. Everything else here is either a finished solid or a mesh. It ships a .STEP too, for anyone without Fusion.

Hammer Battlebot

Tom_Dreyfus, from emancarrillo's original · Thingiverse

CC BY-NC150 g

Dalawang sandata sa isang robot. Really two weapons in one: a full-width plow to get under the other robot and shove it, plus a gear-driven hammer that swings over the top. The only thing here that strikes downward instead of spinning — and the only one that can push and hit.

Runs N20 motors, with extra retention added for them. The designer also links a Fusion 360 copy of the model, so it may be editable CAD rather than a mesh — ⬜ worth checking, because that is the difference between changing a number and fighting a triangle soup.

Crusher

emancarrillo · Thingiverse · the same designer as the hammer bot

CC BY-NC-SA150 g.STEP editable

A hinged, spiked jaw that comes down over the other robot, with a wedge to get under it first. Nothing else here grips — everything else spins, flips or shoves.

Ships a real CAD file — 150G_KRAKEN_ASSY_001.STEP, a proper solid rather than a mesh, so it can be edited, measured and re-cut around our own electronics.

He is also honest about it: "more of a control bot as it doesn't really have the power to crush." That is the right expectation to set with a child — it wins by holding and steering the other robot, not by destroying it. Needs no extra tools, but he warns that prepping the gears and setting the servo limits is fiddly.

BatBotSpin

Ruffson · Thingiverse

CC BY-NC-SA150 g.stp editable

A full horizontal bar on a front bearing mount, sweeping flat and level — the small cousin of the machines that take the side off an opponent. 2× N20 500 rpm for drive, a brushless 1504 for the bar.

Worth putting beside the Beater Bar rather than instead of it: a short beater and a long bar are the same idea at different scales, and comparing them is how a child works out that the tip of a longer bar carries far more energy — and why its mount has to be so much stronger.

It also ships BatBotSpin.stp, and its parts are already split sensibly — Body, Spinner, Support, Cover, Adapter — which is most of the way to a modular bot already.

⚠️ Specs its N20s at 12 V; our parts list is 6 V. Check which before ordering. Parts links go to Ozon (Russian), so source equivalents locally.

Plan B mk.1

jeremywheat · Thingiverse

CC BY-NC-SA150 g.step — every part

Ginawa ito ng isang estudyante, para sa club sa paaralan nila. Designed by a high-school student for his own school club. Long tapered body, front spinner, M2 screws throughout except M3 on the weapon.

Ito ang patunay · this one is the proof. Everything else here was built by an adult hobbyist. This was built by a kid, for a club exactly like ours — which is the most useful thing a child on this page can read.

It also has the most complete CAD of anything we found: Chassis, Lid, Weapon and Wheel each ship as both .stl and .step. And the designer invites questions in the comments.

BatBotDrum

Ruffson · Thingiverse · same designer as BatBotSpin

CC BY-NC-SA150 g.stp editable

A drum — a wide toothed cylinder turning across the front. Steadier than a bar because the weight is spread along it, so it is less likely to throw itself across the arena when it lands a hit.

⭐ Ito ang modular · this pair IS the modular idea. Compare its parts with BatBotSpin: both are Body + Cover + Wheel, and only the weapon differs — Drum on one, Spinner + Support + Adapter on the other. One chassis, two weapons, by one designer, and both ship a .stp.

That is the strongest starting point we have found for a club bot: print the body once per kid, print a different weapon each term.

CRNZ Antweight Modular Kit

Paul Mumby (Orb0) · Combat Robotics New Zealand

CC BY-NC-SA150 g

A whole kit, not one bot: base 2WD pushbot with plow, wedgelets, a 4WD expansion, vertical spinner, horizontal spinner, hugger, grabber/lifter — all on a shared dovetail mount you can design your own module for. Ships an A1 mini print profile and a published build tutorial.

The strongest option on this page for a class, and the upstream of several others here. Watch: it is built around the Kakapo controller, not an ESP32.

Beater Bar Battlebot

TheBlackfish · MakerWorld

CC BY-NC-SA150 g

A spinning beater bar on a CRNZ-derived body, with mounts already cut for N20/N10 gearmotors — the same motors in our parts list.

The designer's own photo shows the bar bent after nearly every fight, and says so. That honesty is worth more than the file: plan on spares.

6-wheel servo flipper

MakerWorld

CC BY-NC-SA150 g

Low, stable, six wheels, and a servo flipper that gets its forks under anything. 2× N20 6V 500 rpm — our motors. Over 50 fights, with a long written guide.

The author's own warning: "not necessarily designed to be easy to build." Not a first project.

Hindi robot, pero gawin ninyoNot robots — but build these anyway

Ang arena, ang sukatan, at ang kontrol. The arena the fight happens in, the gauge that decides whether a robot is legal, the controller that drives it, and spare wheels. None of them is a robot; all of them matter as much as the robots do.

Hindi ito robot — sukatan. Not a robot. A frame your bot must fit through to be legal.

Print this first. It costs a few grams of filament and settles arguments on the day instead of at the event.

Customizable Remote

MakerWorld · 176 reviews · joystick models sold separately (flat / round)

CC BY-NC-SAside build

Isang kontrol na kayo ang gumawa — at may mukha ninyo sa harap. A printed transmitter the kids build themselves, with their own picture or name on the face. It is the only thing on this page that is not a robot, and it may be the most useful.

Bakit ito ang pinakamahalaga · why this one matters most
It makes Lesson 7 real. Right now huling narinig — "last heard" — is a number on a screen. With a controller the kids built, talking to the bot over ESP-NOW, that variable is the time since the last radio packet. Switch the controller off, watch the number climb, watch the weapon stop.

It also teaches inputs, which no module covers yet — a joystick is two potentiometers feeding an ADC, which is Lessons 2 and 4 paying off on something real. And it is cheaper: a second ESP32 is ₱250–400 against ₱800–1,500 for a gamepad. ESP-NOW reaches 100 m+, against Bluetooth's ~10 m.

⚠ The cost, honestly: twenty controllers is twenty more builds and one firmware bug takes out every bot at once — and twenty ESP-NOW transmitters in one room need their peer addresses and channels managed, or a bot answers the wrong child. Solve that before an event, not at one.

Ang arena · The battle box

JEQuad · Thingiverse · built for 150 g AND 450 g robots

CC BYthe venue

Dito nagaganap ang laban — at dito nananatiling ligtas ang lahat. Angled polycarbonate walls, a lit frame and a match timer. This is where a fight happens and, more to the point, where the pieces stay when something lets go.

Bakit tatsulok · why the triangle matters. It is not styling. The angled walls open a clear viewing line from BOTH sides, where a plain box really only works looked at from above — and at an event the audience is the point. The slope also deflects anything that comes off a robot down and inward rather than straight up at the people watching.

Real numbers, which is what makes it useful: 5 mm polycarbonate walls · audience side panels 1276 × 943 mm, two of them · triangles cut corner-to-corner from one 937 × 937 mm sheet with a jigsaw.

⚠️ The designer says plainly it is "for reference, not as full plans" — treat the dimensions as a starting point, not a cut list. Note also that our own notes specify 4.5 mm polycarbonate, not 5 mm; settle that before anyone buys a sheet.
