Designed and built 7 sumo robots from scratch for the Bluevale Collegiate Institute robotics club — intended as a hands-on learning platform for students new to electronics and embedded systems.

Each robot features a fully 3D-printed chassis designed in Onshape with a low wedge profile and grippy wheel mounts, driven by two TT gear motors through an L298N dual motor driver controlled by an Arduino. Firmware was written from scratch, implementing IR line detection to stay on the sumo ring and opponent detection to attack.

Every unit was built ground-up — CAD, PCB wiring, motor driver tuning, and firmware — then used in club sessions to teach students robotics fundamentals through direct competition.

• Low wedge chassis designed in Onshape for sumo ring stability and opponent scooping
• IR sensors for ring edge detection + opponent detection with reactive attack logic
• L298N dual motor driver with PWM speed control for differential steering
• 7 identical units built and deployed for club-wide student competitions
