Implementation of a Smart Robotic Waste Collection System Using Bluetooth Technology

Abstract

The rapid increase in urban waste generation demands efficient and automated waste management solutions to improve hygiene and operational efficiency. This paper presents the design and implementation of a Bluetooth-based smart robotic dustbin system capable of autonomous navigation and waste collection. The proposed system integrates an ESP32 as the central controller along with ultrasonic sensors for obstacle detection and IR sensors for proximity sensing. Wireless communication and control are enabled through Bluetooth connectivity, allowing remote operation of the system. The robotic platform is driven by DC motors for mobility and servo motors for automated lid actuation. Additionally, visual and audio indicators using LEDs and buzzers provide real-time system status feedback. The system is designed to reduce manual intervention in waste collection processes while ensuring efficient operation in dynamic environments. Experimental implementation demonstrates reliable obstacle avoidance, smooth navigation, and effective waste handling capabilities. The proposed solution enhances cleanliness and operational safety, making it suitable for deployment in public and private environments such as hospitals, offices, shopping malls, and residential complexes. Overall, the system contributes to the development of intelligent and automated waste management solutions using low-cost embedded technologies.
