HUBMOTOR WEAPONS
Maximum destruction with custom, off the shelf combat robotics weapons!
HUBMOTORS
The basic concept of a hubmotor for combat robotics is very simple. Instead of a weapon attached to an axle and driven by a motor and belt or similar, the motor is part of the weapon, and the weapon is attached directly to the bell of the motor, and since the motor is an outrunner, the outside of the motor and the weapon mounted to it all rotate.
Safety First!
Even small combat bots can be very destructive and can pack the kinetic energy of a bullet. If you’re just getting started, start with a beginner bot and wait to weaponize. Always use a test box with a bot rated “destructive”. Click here to learn more.
Always take a bot with a spinning weapon seriously. They are dangerous. As with any other sport, be safe!
Weapons
No CAD? No Problem.
Hubmotors usually mean custom weapon designs—but not everyone has the time or tools to make their own.
We’ve got you covered.
Drop-in, battle-ready blades engineered for maximum damage. No design work. No delays. Just bolt on and win.
Smash harder. Build faster. Worry less.
Brands
We’re proud to carry hubmotor weapons from both Just ‘Cuz Robotics and Repeat Robotics—two of the top names in combat robotics.
These battle-tested weapons are trusted by top builders for elite performance, precision engineering, and availability at a price that makes sense.
ItGresa is a close partner with both brands—and now, you can get their gear, all in one place.

AR500 VS AR600
The most common type of steel for combat robotics weapons are AR500 and AR600.
- AR600 is harder than AR500, so it keeps a sharper edge longer and hits harder—but it’s also more brittle.
- AR500 is tougher and more durable.
If damage is the most critical, consider AR600. Conversely, AR500 is a great choice for both ruggedness and staying power in the ring.

The Repeat Robotics hubmotors are mounted to the weapon with screws that hold the blade onto the motor. A Repeat Robotics weapon shaft is also necessary.
The Just ‘Cuz hubmotors have a proprietary shape that locks the blade into the motor. The Sledgehog blade fits the RDY-5022 motor, while the while the Snaggletooth fits the RDY-5536 motor. They are NOT interchangeable.
Newer versions of the 5022 motor do not require the spacers, but they are included with purchase of the 0.125″ Sledgehog blade. Sledgehog is made of AR600 steel.
