Bionic Jellyfish Robot! Northwestern Polytechnical University Has Launched Another Underwater Weapon, Equipped with AI Detection Capabilities to Counter US Submarines!
Recently, Professor Tao Kai's team from Northwestern Polytechnical University has developed a "Underwater Ghost" bionic jellyfish robot, which is no ordinary feat.
First of all, the robot's "stealth" capabilities are top-notch. It is completely transparent, with a diameter of only 12 centimeters, slightly smaller than an adult's palm, and weighs only 56 grams, barely noticeable in your pocket. Underwater, it moves using a vortex ring propulsion method that mimics the muscle structure of a jellyfish, not only making its movements natural and smooth, but also producing extremely low noise, achieving "silent" navigation.
Imagine this: in the vast ocean, a small object that almost doesn't make any sound and looks no different from ordinary marine life is swimming around. The difficulty of detecting it with traditional sonar systems is self-evident.
This robot is not remotely controlled. It integrates artificial intelligence (AI) internally, achieving what is called "embodied intelligence." This means it can perceive the environment and make decisions independently underwater, without constantly receiving instructions from the surface or a mother ship. This greatly enhances its independent operation and survival capabilities in complex underwater environments.
So what is the core technology that drives this "underwater ghost"? It is the team's independently developed electrostatic hydraulic muscle actuator and an innovative hydrogel electrode material. In simple terms, it uses electric fields to simulate the neural signals that control the contraction and expansion of jellyfish muscles. This method is extremely energy-efficient, with the entire robot's drive array power consumption being as low as an astonishing 28.5 milliwatts.
What does this mean? A regular household LED night light may have a power of about 1 watt, and the power consumption of this entire drive system is less than one-thirtieth of that. The ultra-low power consumption directly brings the potential for ultra-long endurance, laying a solid energy foundation for it to carry out long-term, covert underwater missions.
With these characteristics, what can it do? Basically, it is tailored for US nuclear submarines. Not only is it small, but it is also intelligent, with an ultra-long standby time, and can be used specifically to locate US nuclear submarines using passive sonar.
