A research team led by Professor Tao Kai from the School of Mechanical Engineering at Northwestern Polytechnical University in Shaanxi, northwestern China, has developed a fully transparent, jellyfish-shaped bionic robot capable of intelligent underwater exploration and real-time environmental monitoring.
Dubbed the "Underwater Phantom," the robot becomes nearly invisible to the naked eye when submerged, blending seamlessly into its surroundings. Measuring just 120 millimeters in diameter and weighing 56 grams, it is powered by an electrohydraulic artificial muscle actuator and innovative hydrogel electrode materials independently developed by the team.
These technologies precisely replicate the vortex-ring propulsion mechanism of the real jellyfish, enabling the robot to achieve efficient, almost silent, movement underwater.
With an ultra-low power consumption of only 28.5 milliwatts, the robot demonstrates strong potential for long-term, covert underwater operations.
The researchers have also integrated AI into the bionic platform. Equipped with a miniature camera module and an embedded AI processing chip, the robot can hover stably in dynamic aquatic environments and accurately identify specific underwater targets.
The jellyfish-inspired robot's low energy use, minimal noise, and high level of biomimicry make it especially well-suited for deep-sea monitoring, ecological observation in sensitive marine zones, and precision inspection of underwater facilities.
The team plans to enhance the robot's performance and promote its application in areas such as deep-sea scientific exploration and long-term intelligent underwater monitoring, contributing to national priorities in marine technology and environmental research.
