According to New Atlas, researchers at Northwestern Polytechnical University in Xi’an, Shaanxi have developed a remarkably lifelike bionic jellyfish robot measuring just 12 cm in diameter and weighing 56 grams. The “underwater ghost” uses novel electro-hydraulic muscle actuators and hydrogel electrode materials to replicate jellyfish propulsion while consuming only 28.5 milliwatts of power. Led by Professor Kai Tao, the transparent robot features a built-in camera and AI chip for object recognition and was demonstrated on state media CCTV successfully identifying objects including the NPU emblem and a clownfish. On October 21, Professor Tao told Science and Technology Daily that the robot’s low power consumption and high biomimetic characteristics give it unique advantages for covert deep-sea monitoring and ecological observation. This development represents a significant advancement in biomimetic robotics that could transform underwater exploration and surveillance.

The New Frontier of Covert Underwater Operations
This bionic jellyfish represents a paradigm shift in underwater surveillance technology. Traditional underwater drones and remotely operated vehicles (ROVs) are typically large, noisy, and energy-intensive, making them easily detectable and limiting their operational duration. The jellyfish robot’s minimal power requirements and near-perfect biomimicry create unprecedented opportunities for long-duration covert monitoring missions. Military applications are particularly compelling – these devices could monitor naval bases, track submarine movements, or conduct intelligence gathering in contested waters while appearing as natural marine life. The technology’s development at Northwestern Polytechnical University, which has strong ties to China’s defense industry, suggests potential dual-use applications that could alter underwater warfare and intelligence collection capabilities.
Transforming Marine Science and Environmental Monitoring
Beyond military applications, this technology could revolutionize marine biology and environmental monitoring. Traditional research methods often disturb marine ecosystems, with large vessels and equipment altering animal behavior and damaging delicate habitats. A biomimetic approach enables non-invasive observation of marine life in their natural states. The jellyfish robot’s ability to operate in sensitive ecological areas without disruption could provide unprecedented insights into deep-sea ecosystems, coral reef health, and marine animal behavior. However, as the source notes, there’s a significant risk of predation – sea turtles and other marine animals that naturally consume jellyfish might mistake these robots for food, potentially causing harm to protected species. This echoes concerns about plastic pollution impacting marine life, creating an ethical dilemma for researchers.
Disrupting the Underwater Robotics Market
The emergence of highly biomimetic robots threatens to disrupt the established underwater robotics market dominated by companies like Ocean Infinity, Saab Seaeye, and Teledyne Marine. These traditional players focus on larger, more powerful ROVs and autonomous underwater vehicles (AUVs) designed for industrial applications like offshore energy, pipeline inspection, and search operations. The jellyfish robot’s extreme efficiency and stealth capabilities create a new market segment that could capture missions requiring extended duration and minimal detectability. We’re likely to see increased investment in biomimetic robotics from both defense contractors and environmental technology companies, with Northwestern Polytechnical University’s previous work on a 470-kg manta ray robot demonstrating their ongoing commitment to this approach.
The Engineering Breakthroughs Behind the Biomimicry
What makes this development particularly significant are the underlying technological innovations. The electrostatic hydraulic actuator (EHA) system represents a major advancement in soft robotics, enabling precise control of flexible materials to replicate biological movement. This builds upon earlier research into jellyfish-inspired soft robotics but achieves unprecedented realism. The integration of AI processing directly on the robot, rather than relying on external computation, enables real-time object recognition while maintaining the device’s autonomy and stealth. These technical achievements suggest we’re approaching a tipping point where biomimetic robots can outperform traditional mechanical designs for specific applications, particularly those requiring energy efficiency and natural appearance.
The Intensifying Global Race in Biomimetic Robotics
This development highlights the accelerating global competition in biomimetic robotics. While Chinese researchers are advancing jellyfish robotics, institutions like Caltech has been developing biohybrid jellyfish applications and other universities worldwide are exploring similar concepts. The differing approaches reveal strategic priorities – Caltech’s collaboration with bioethicists emphasizes responsible development, while the Chinese project appears focused on practical applications and demonstration of capability. This technological race extends beyond academic prestige to encompass economic and military advantages, with nations recognizing that leadership in biomimetic robotics could translate into significant strategic benefits in both civilian and defense sectors.

Navigating the Coming Regulatory Challenges
As these technologies mature, we’ll face complex regulatory questions about their deployment. The very features that make bionic jellyfish effective – their stealth and natural appearance – also raise concerns about unauthorized surveillance and environmental impact. International waters currently lack comprehensive frameworks for regulating biomimetic surveillance devices, creating potential for conflict and espionage allegations. Environmental agencies will need to develop guidelines to prevent harm to marine ecosystems, particularly given the predation risks identified in the research. The technology’s dual-use nature means export controls and non-proliferation efforts will become increasingly important, similar to regulations governing other sensitive technologies with both civilian and military applications.
Where This Technology Is Headed Next
Looking forward, we can expect rapid evolution of this technology platform. The current 12 cm design likely represents just the beginning – future iterations may include smaller versions for more discreet operations or larger models capable of carrying additional sensors and equipment. Integration with swarm intelligence could enable coordinated groups of bionic jellyfish to perform complex monitoring tasks across large ocean areas. Power innovations, potentially including energy harvesting from ocean currents or temperature gradients, could extend mission durations from days to months or years. As research into advanced biomimetic systems continues, we’re likely to see increasingly sophisticated underwater robots that blur the line between biological and artificial systems even further.
