The surge in urban population across Nigeria has intensified challenges in waste management, making traditional, manual collection methods increasingly inadequate. This study proposes a smart solution through the design and deployment of a garbage collection robot that utilizes IoT technology, operable via a mobile application for real-time monitoring and control. The robot, equipped with advanced sensors and mecanum wheels, adeptly navigates complex terrains and densely populated urban areas, specifically demonstrated in the Gidan-Kwano Metropolis. Field trials conducted in the Bahago and DHF communities showcased the robot’s efficiency, reducing garbage collection time by 15%. This innovative approach aligns with Sustainable Development Goal 11, aiming to enhance urban sustainability and resource efficiency. The smart garbage collection robot presents a promising advancement for improving waste management processes in rapidly urbanizing regions.
