Ironbot
Our 500 g sumo robot packs agile maneuverability and raw power to dominate every opponent in the ring.
Our Core Technologies
We prototype every component in durable PLA plastic using high-precision FDM 3D printing, designing and refining each part directly in Fusion 360 to guarantee perfect fit, form, and function. Our streamlined workflow lets us move from CAD sketch to test-ready prototype in under 48 hours, so we can rapidly iterate and optimize geometry, weight, and strength. This approach keeps the robot exceptionally lightweight yet remarkably robust—and makes adapting to new sensors, motors, or rule changes effortless.
| PCB We laid out the PCB in EwasyIDE, then transferred the toner-based copper pattern onto a Textolite (FR-4) board. Next, we immersed it in a homemade etchant of hydrogen peroxide, salt, and citric acid to dissolve all unwanted copper, rinsed and stripped the toner, then drilled the component holes and soldered on each part—completed and ready to power up. |
Wheels
We 3D-printed the wheel hubs on our FDM printer, then built a simple mold and cast a layer of silicone around each rim. The flexible silicone treads conform perfectly to the ring surface, delivering exceptional grip and allowing our sumo robot to outpush every opponent with ease.

Finally, we develop all the control firmware in the Arduino IDE: writing clean C++ sketches that initialize and read our IR and ultrasonic sensors, drive the motors via PWM and H-bridge drivers, and implement a simple state machine for “search, attack, and retreat.” We integrate PID loops for smooth acceleration and precise turns, monitor battery voltage, and use the Serial Monitor for on-the-fly debugging. Once the code is uploaded via USB to our Arduino Nano, we run live tests in the ring to tweak sensor thresholds and PID gains—locking everything down only when each bout runs flawlessly.

I’m a multidisciplinary maker who turns ideas into finished products—from smart keychains with air-quality, humidity, temperature, CO₂, and GPS sensors paired with iOS/Android apps to sleek packaging prototypes and E-Ink display modules. I also design, 3D-print, and program competition robots on Arduino, VEX, and FTC platforms—laying out and etching PCBs in EwasyIDE, casting silicone treads on wheel hubs, and writing real-time PID firmware in the Arduino IDE—all within a rapid 24–48 hour prototyping cycle.
