Sumo Robot (GRA 2026)
Competition sumo robotics for the GRA 2026 season — ESP32-S3 firmware, motor control, and sensor integration, with complete Georgian-language assembly documentation.
My Role
Firmware & Electronics — wrote the ESP32-S3 firmware, integrated motor drivers and sensors, handled the wiring, and produced the full assembly documentation in Georgian.
Project Type
Robotics — competition robot built for the Georgian Robotics Association’s 2026 season.
Tools Used
ESP32-S3, C/C++, motor drivers, sensor integration, wiring & electronics, technical documentation

Problem & Solutions
Real-Time Control on a Microcontroller
Problem
A sumo match gives the robot milliseconds to detect an opponent and respond — all within tight weight, power, and processing constraints.
Solution
A lean firmware loop on the ESP32-S3 fuses sensor input with tuned motor control, keeping reaction time low without starving any subsystem.
Documentation as Part of the Build
Problem
Robotics learning materials barely exist in Georgian, which locks students out of reproducing even a well-engineered robot.
Solution
Full assembly documentation written in Georgian — wiring included — ships with the robot, so the build doubles as a teaching resource.
