Water quality monitoring system based on robotic dolphin

Abstract

To meet the demands of online, safe and overall monitoring of the water quality, a water quality monitoring system based on robotic dolphin is developed, enlightened by the dolphin's swimming ability with high efficiency and good maneuverability. The system is composed of fixed monitoring nodes, robotic dolphin node and a console, and the water quality parameters such as PH value, conductivity, dissolved oxygen and turbidity are acquired by the coordination of the fixed measuring and dynamic measuring. The fixed monitoring nodes support solar energy power supply, self-organized network and multi-hop transfer. The robotic dolphin, sealed by the silica gel coat, possesses the characteristics of good locomotion and low noise due to its imitation of the dolphin's shape and dorsoventral movement. As a safe, new and fast water quality monitoring mode, the system will play an important role in the environmental protection of harbors, coastal waters, lakes and rivers.
