Design and Implementation of Trash Collection System for Smart Cities

This paper aims to propose the design and implementation of a microcontroller-based autonomous trash collection device for indoor applications in smart cities. The proposed work demonstrates the working of a prototype model: ROBOBIN along with its accessories using Atmega328p. The different ways of implementations are discussed. This model uses a combination of passive infrared (PIR) sensor, ultrasonic sensor, and optical tracker for navigation. The device is specifically designed to be installed in hospitals and food courts. Experimental results reveal that the device is cost-effective and outperforms the state-of-the-art methods.
