Hey everyone! After three months of development and six rounds of iteration, we’re proud to introduce the FR-01B Fighting Robot Kit.

The kit comes with 124 parts (including screws) and takes about 2–3 hours to assemble. With its awesome look and a variety of customizable robot gears, we believe this kit will bring you plenty of fun—both in the build and in the battles!

We’ve put together a detailed and awesome assembly guide to help you build your own mecha—and bring your mecha dream to life!

We’ve provided color-separated print profiles, along with test files for trying out different schemes—so you can easily customize your mecha with a cool look of your own；

We’ve also designed a variety of customizable weapon mounts and included a universal model to help you attach your own weapon designs to the robot. Let your imagination run wild—equip your robot with all kinds of weapons, or even try AI-generated creations；

The FR-01B currently supports full omnidirectional movement, 120° waist rotation, right arm swings, and both single-shot and burst fire for its weapon. With practice, you can even pull off combos, blocks, and other advanced moves—bring down your opponent’s armor with thrilling battles and claim victory!

Enjoy building, unleash your creativity, and most of all—have fun!

Future plan

We’re preparing an advanced expansion kit—the FR-01P Fighting Robot.
It comes with our custom-designed PCB board featuring sound and light effects, giving your robot dynamic battle sounds and lighting. With just one additional printed part, it’s fully compatible with the FR-01B kit.

Alongside this, we’ll also release a defense tower for the upcoming base-attack gameplay mode. The tower features hit detection and scoring functions, as well as destruction sound and light effects. Both the FR-01P Fighting Robot Kit and the defense tower will be available on MakerWorld in the next 1–2 weeks—stay tuned!
