TL;DR
Iulia Feroli transformed a basic Elegoo robot car kit into an intelligent face-tracking robot using an Arduino UNO Q. Originally, the kit featured an Arduino UNO Rev3, which allowed for simple tasks like obstacle avoidance and line-following. However, Feroli upgraded to the UNO Q, which has a more powerful STM32 microcontroller running Linux, vastly improving the robot's capabilities.
