On the 21st, it was learned from Sun Yat sen University that the "Polar Frog" dual motion mode underwater robot (hereinafter referred to as the "Polar Frog" AUV), independently developed by Chinese researchers, has successfully completed its ice diving mission during a scientific expedition in the Arctic Ocean, providing key technical support for studying the ice bottom environment of the Arctic Ocean. It is reported that the "Polar Frog" AUV has two motion modes: underwater cruising and crawling, which can be flexibly switched in complex environments. It is equipped with various types of sensing and imaging devices such as underwater binocular cameras and multi beam sonar. In the 2025 "Sun Yat sen University Polar" Arctic Ocean Scientific Expedition, the "Polar Frog" AUV completed two diving missions in low-density and high-density ice areas, with stable performance and system verification of its maneuverability. It also achieved comprehensive investigation of the underwater hydrological environment and ice morphology. Professor Chen Zhuoqi, leader of the Polar Science Expedition Team at Sun Yat sen University, said, "The stable performance of the 'Polar Frog' AUV in polar environments demonstrates the potential and scientific research value of China's independently developed new submersible in extreme environments. ”It is reported that during the investigation, four scientific expedition team members conducted underwater operations in the high latitude ice area of the Arctic Ocean, using the "Polar Frog" AUV to achieve joint detection of ice bottom terrain and underwater environment. Li Yibo, a doctoral student and research team member at the School of Remote Sensing Science and Technology at Sun Yat sen University, introduced that compared to traditional unmanned underwater vehicles, the "Polar Frog" AUV has significant advantages such as lightweight, high maneuverability, and multimodal motion, and can adapt to diverse observation needs.
