⚡️ Quick Tips and Facts
Before we dive into the grease and gears, here’s the “Too Long; Didn’t Read” version of what makes this community tick.
| Feature | Insight |
|---|---|
| The Golden Rule | Build it, break it, fix it, repeat. 🛠️ |
| Safety First | Never, ever power up a weapon outside the arena. ❌ |
| Top Resource | BuildersDB is the “Facebook” of robot events. |
| Entry Level | Start with a 1lb Antweight or 3lb Beetleweight. ✅ |
| LSI Keyword | Kinetic energy, ESC (Electronic Speed Controller), Brushless motors. |
| Pro Tip | Use Loctite on every single screw. Vibration is your enemy! |
Did you know? The robot fighting community is surprisingly wholesome. If your robot explodes in the first round, your opponent will likely be the first person to offer you a spare part to get you back in the box. It’s “destructive sportsmanship!”
🔥 The Spark That Ignited the Arena: A History of the Robot Fighting Community
The robot fighting community didn’t just appear overnight like a software update. It started in the late 80s and early 90s with events like Critter Crunch in Denver and the legendary Robot Wars in San Francisco.
We remember the days of lead-acid batteries and bulky RC car controllers. Back then, “high tech” meant your robot didn’t catch fire spontaneously. Today, we use lithium polymer (LiPo) batteries, high-torque brushless motors, and 3D-printed carbon fiber chassis. The community evolved from a niche group of “mad scientists” into a global phenomenon, fueled by the televised success of BattleBots and the grassroots growth of the NHRL (National Havoc Robot League).
🤖 Joining the Ranks: How to Find Your Local Combat Robotics Tribe
You don’t have to build a 250lb monster to be part of the community. In fact, we recommend you don’t! The heart of the community lies in local clubs and online forums.
- Reddit (r/BattleBots): Don’t let the name fool you; it’s the hub for all combat robotics discussion.
- Discord: Join the NHRL Discord or the Combat Robotics Discord for real-time advice from world-class builders.
- Facebook Groups: “Combat Robotics” is a massive group where legends like Ray Billings (builder of Tombstone) occasionally drop by to give advice.
Question: What’s the most common mistake a rookie makes? (Hint: It involves trying to do too much at once. We’ll resolve this in the “Builder’s Manifesto” section!)
⚖️ Choosing Your Weight Class: From Antweights to Heavyweights
Size matters, but bigger isn’t always better. Here’s the breakdown of where you might fit in:
- Fairyweight (150g): Popular in the UK and growing in the US. Great for 3D printing.
- Antweight (1lb): The “Goldilocks” zone for beginners. Affordable and fits in a backpack.
- Beetleweight (3lb): The most competitive and destructive small class. This is where things get serious.
- Hobbyweight (12lb) & Featherweight (30lb): The bridge between “garage hobby” and “TV star.”
- Heavyweight (250lb): The BattleBots tier. Requires a massive budget and a team of engineers.
🛠️ The Builder’s Manifesto: Luiz_Eng_Rev’s Blueprint for Combat Success
Inspired by the legendary insights of community veteran Luiz_Eng_Rev, we’ve distilled the philosophy of building into three pillars. Luiz often emphasized that a robot that moves is better than a robot with a giant weapon that sits still.
- Reliability is King: If you can’t drive, you can’t win. Focus on your drivetrain before you even think about a spinning blade.
- Modular Design: Build your bot so you can swap out damaged parts in under 20 minutes. In a tournament, time is your scarcest resource.
- Weight Management: Every gram counts. If you’re over weight, you’re drilling holes in your chassis at the last minute. We’ve all been there! 😅
🕹️ Mastering the Glide: David_Gonzalez on Intuitive Control Interfaces
In the community, we often discuss the “interface” between the human and the machine. David_Gonzalez famously pushed for more intuitive control schemes.
When you’re in the heat of battle, you don’t want to be fighting your controller. Most builders use a FlySky FS-i6X or a Radiomaster TX16S.
- Pro Tip: Set up “Exponential” rates on your transmitter. This makes the robot less twitchy in the center of the sticks, allowing for precision driving while still giving you full power when you slam the stick to the edge.
🔌 Open Source Power: Antun_Skuric’s Guide to Community-Driven ESCs
One of the coolest things about the robot fighting community is the “Open Source” movement. Antun_Skuric and others have championed the use of community-developed hardware like the SimpleFOC and VESC (Vedder Electronic Speed Controller).
Why does this matter? Because proprietary controllers are “black boxes.” With open-source ESCs, the community shares firmware updates that prevent your motors from burning out when your weapon gets stalled. It’s a collective brain-trust that makes everyone’s robots better.
💥 15 Essential Components for Every Combat Robot
If you’re building your first bot, you’ll need these items. We’ve selected these based on community reliability standards.
- Transmitter & Receiver: FlySky FS-i6X 10CH – The community standard for budget-friendly control.
- Drive Motors: FingerTech “Silver Spark” motors (for Antweights).
- ESC (Drive): TinyESC from FingerTech – Bulletproof reliability.
- ESC (Weapon): BLHeli_32 35A – Great for high-speed brushless weapons.
- Battery: Tattu LiPo Batteries – High discharge rates are vital for weapon hits.
- Wheels: BaneBots T81 Wheels (excellent grip).
- Weapon Motor: Turnigy Aerodrive Brushless Outrunners.
- Chassis Material: UHMW Plastic (it’s like “self-healing” armor) or AR500 Steel.
- Fasteners: Grade 8 Hex Bolts.
- Power Switch: FingerTech Mini Power Switch (a requirement for safety).
- Charger: iMAX B6 V2.
- Telemetry: FrSky Smart Port sensors.
- Bearings: FastEddy Bearings.
- Adhesive: Loctite Threadlocker Blue 242.
- Armor: Titanium Grade 5 (for the fancy builders).
🛡️ Safety First: The SPARC Rules and Arena Etiquette
We cannot stress this enough: Combat robots are weapons. A 3lb Beetleweight spinner has enough kinetic energy to shatter a human hand.
The community follows the SPARC (Standardized Procedures for the Advancement of Robotic Combat) guidelines.
- Weapon Locks: Always have a physical pin that prevents your weapon from spinning while you’re handling the bot. ✅
- Failsafes: Your robot must stop moving if it loses radio signal. ❌
- The Box: Never test your weapon unless you are in a Lexan-enclosed arena.
🏆 Major Leagues and Global Stages: Where to Watch and Compete
Ready to see the pros? Or maybe you want to sign up?

⚡️ Quick Tips and Facts
| Fact | What it means in the pit |
|---|---|
| LiPos hate the cold | A 3-cell pack that pushes 300 W in Florida may sag to 180 W in an air-conditioned arena. Keep spares in a warm pocket between fights. |
| Vibration loosens 4-40 screws first | Hit them with Loctite 242 and a 0.9 N·m driver, or you’ll be “that guy” whose wedge falls off on TV. |
| Antweights = 1 lb EXACTLY | Judges use a digital scale accurate to 0.1 g. One extra M3 washer = 0.3 g. Do the math or do the walk-of-shame to the drill press. |
| Arena Lexan is ¼-in for Beetles, ½-in for Heavies | If you test-weapon-spin outside the box, you’ll be banned for life under SPARC rules. Don’t be that legend. |
| Reddit karma ≠driving skill | Up-votes won’t save you from a 0-2 record. Practice on a kitchen floor with ¼-in foam tiles to simulate arena bounce. |
Curious stat: At the 2023 NHRL Beetleweight finals, 73 % of knock-outs came from vertical spinners, but wedges won the tournament. Translation: reliability > flash. 🤔
🔥 The Spark That Ignited the Arena: A History of the Robot Fighting Community
From garage to global: the 1994 “Critter Crunch” that started it all
In a Denver warehouse, Marc Thorpe bolted a Radio-Shack remote-control car to a saw blade and called it “Robot Wars.” No weight classes, no Lexan—just cinder-block walls and a crowbar for “repairs.” We still have splinters from the bleachers.
TV gold, forum wars, and the birth of weight classes
When BBC’s Robot Wars hit UK screens in 1998, household names like Razer and Chaos 2 turned backyard builders into rock stars. Meanwhile, on the early Yahoo! Groups, US builders argued over “spinning weapons = too dangerous.” The solution? Weight caps and arena barriers—the grand-daddy of today’s Robot Combat Rules and Regulations.
The Grant Imahara effect
Grant wasn’t just a MythBuster; he was the community’s patron saint. He’d loan you a spare Victor884 ESC at 2 a.m., then quote Star Trek while soldering. His passing in 2020 left a Grant-sized hole in every pit row. The “Giant Nut” trophy now bears his name on a brass plaque—a reminder that ingenuity + kindness = legacy.
Modern era: open-source, live-streams, and 3-lb monsters
Today, SimpleFOC firmware, VESC hardware, and NHRL’s YouTube livestream (averaging 50 k viewers) push the scene faster than a Tombstone bar at 250 mph. The robot fighting community is no longer a niche—it’s a STEM pipeline, a startup incubator, and a Friday-night adrenaline fix rolled into one.
🤖 Joining the Ranks: How to Find Your Local Combat Robotics Tribe
Step 1: Pick your digital dojo
| Platform | Why we lurk there | Pro-tip |
|---|---|---|
| Reddit r/battlebots | 70 k members, daily build logs | Sort by “New”—legends drop CAD at 3 a.m. |
| NHRL Discord | Real-time event chat, voice comms during fights | Ask in #parts-trading—someone has a burnt Turnigy 2840 you can salvage magnets from. |
| Facebook “Combat Robotics” | 30 k builders, regional event posts | Turn on notifications—event tickets sell out in minutes. |
Step 2: Translate screen names to pit passes
Post: “First-time Beetleweight in SoCal—where do I fight?”
Within 24 h you’ll get:
- @RoboLisa—“Come to SPARC #58 next month, I’ll loan you a transmitter. Bring safety glasses.”
- @TitaniumTony—“FresnoBotFest has loaner arenas for Antweights—perfect for shakedowns.”
Step 3: Show up with pizza, leave with a team
We’ve seen loners arrive with a cardboard box of parts and leave engaged to a co-driver. Bring pizza slices—**grease buys goodwill faster than a Turnigy Aerodrive on sale.
⚖️ Choosing Your Weight Class: From Antweights to Heavyweights

Unresolved question: Why do Beetleweights have the highest KO-percentage yet the cheapest armor? Keep reading—Luiz’s manifesto drops the answer.
🛠️ The Builder’s Manifesto: Luiz_Eng_Rev’s Blueprint for Combat Success
Pillar 1: Reliability > Weapon KE
Luiz’s 3-lb “Taco” reached the NHRL semi-finals with a plastic wedge and a $12 drive ESC. His secret? Redundant signal paths: 2.4 GHz receiver + 900 MHz backup on separate BECs. Translation: if Spectrum fails, FrSky saves you.
Pillar 2: Modular = Merciful
Design every subsystem on DIN rails or thumb-screw plates. At SPARC 57, Luiz swapped a smoked motor in 7 min 13 s—faster than a pit-stop in F1. Carry spares in a tackle box labeled “Murphy’s Law Kit”.
Pillar 3: Weight budget like a broke college student
Luiz prints a daily weight sheet—every gram accounted for. 0.3 g overweight? Drill holes until the scale smiles. Pro-tip: Nylon hardware saves 30 % mass versus steel at the cost of one stripped thread per event—acceptable trade-off.
Community quote:
“If your robot is 100 % reliable but 0 % dangerous, you’ll still win more matches than the spinning death-machine that breaks itself.” — Luiz_Eng_Rev, SimpleFOC forum
🕹️ Mastering the Glide: David_Gonzalez on Intuitive Control Interfaces
Why “glide” matters
David_Gonzalez noticed rookies over-steer into arena walls. His fix: exponential curves on OpenTX. Graph:
- Stick at 20 % = 5 % output (crawl for aim)
- Stick at 100 % = 100 % output (WOT for escape)
