Discover the innovative Refreshment Replenishing Robot (RRR) designed to build a line-following mechanism that minimizes human intervention and eliminates the need for a microcontroller. This project aims to digitally control the robot's movements and integrate its mechanical aspects with the base. The robot features a carefully designed circuit that utilizes light sensors and logic gates to ensure efficient operation. Despite challenges such as circuit triggering and size minimization, significant progress has been made, including the completion of the robot circuit and most of the enclosure.
