The AquaCrusader is a fully autonomous, AI-powered aquatic robot innovation designed by Snazo Nzama and Elihle Msomi to collect micro plastics (MPs) and nanoplastics (NPs) from streams, rivers, . Operated by a Raspberry Pi and Arduino UNO R4, it uses ultrasonic sensors, GPS mapping, and real- time AI navigation to function without human intervention. Powered by solar panels (effective even underwater) and hydro energy, the Aqua Crusader offers sustainable operation. Its dual-chamber design separates the control system from a highly effective filtration system capable of capturing both MPs and NPs, ensuring minimal disruption to aquatic ecosystems.

Engineered with an eco-friendly, hydrodynamic structure and camouflaged in eco-friendly dark blue paint to blend with its environment, the AquaCrusader is waterproof, insulated, and durable even in harsh aquatic ecosystem conditions. It supports remote control options and emergency manual override, while a gyroscope ensures it remains stable in strong water currents and water pressure. Environmentally conscious and scalable, the AquaCrusader aligns with key South African environmental laws and the United Nations Sustainable Development Goals (SDGs 3, 6, and 13). It exemplifies the 2025 World Environment Day theme, “Solutions to Plastic Pollution,” by offering an innovative, intelligent, and eco-conscious solution to one of the planet’s most pressing environmental challenges: plastic pollution.
