Sumo nano

This robot is a 25mm cube, weighing 25 grams and its designed to compete in a sumo nano competition. Its main components are: ESP32-WROOM-32U - WiFi enabled CPU , TB6612FNG motor driver, and VL53L1CXV0FY TOF distance sensor all packed together in a tiny form factor. My role in this project was to design a printable 3D model, PCB board and ROSify the whole thing.

Here is the deconstructed version but controlled through WiFi.
