1. INTRODUCTION

Rivers serve as indispensable freshwater resources that sustain ecological stability, agricultural productivity, and human survival. However, accelerated urbanization and

inefficientsolidwastemanagementhavetransformedthese vital waterways into primary transit points for anthropogenicdebris.Everyyear,millionsoftonsofplastic waste transition from urban drainage systems into the oceans, creating a global ecological emergency. Once introduced into the aquatic environment, these pollutants degrade water quality and decompose into microplastics that lethally compromise local wildlife and downstream ecosystems. Despite the escalating severity of water contamination,currentremediationmethodologiesremain fundamentally outdated. Conventional cleaning predominantlyreliesonmanuallabor,whichisinherently slow, economically inefficient, and subjects workers to hazardous,pollutedenvironments.Conversely,large-scale industrial dredgers are often prohibitively expensive for smaller municipalities and lack the agility required to navigateonnarroworshallowriversegments.Thiscreatesa critical "technological gap" for an affordable, agile, and intelligent system capable of continuous surface-level remediationwithouthumanrisk.Toaddressthischallenge, this project presents the implementation of Aquaboat, a semi-autonomousrobotdesignedfortargetedaquaticwaste management.Bridgingthegapbetweenmanual laborand heavymachinery,itutilizesahigh-torquequad-propulsion systemtomaintainprecisemaneuverabilityundervariable river currents.
