China has introduced a new frontier in marine technology, combining innovations from the space and maritime industries. Shenyang Aerospace Xinguang Group has developed the world’s first robotic whale shark, an advanced bionic device capable of replicating the movements of a real whale shark. The robot promises significant applications in scientific research and underwater operations.

Key Points:

- Pioneering project: The first robotic whale shark developed in China marks a major breakthrough in marine robotics.
- Advanced capabilities: The robot can swim, dive and move its mouth, equipped with optical cameras and sonar technology.
- Environmental sustainability: The robot’s enclosed design minimizes the risk of pollution and interference with marine life.
- Future applications: Possible evolution to a range of bionic robots including dolphins and orcas, with impacts on research and industry.

A new milestone in marine technology has been reached in China, thanks to the fusion of space innovation and maritime engineering. The Shenyang Aerospace Xinguang Group, affiliated with the China Aerospace Science and Industry Corporation, has successfully developed the world’s first robotic whale shark, a bionic product that represents a significant breakthrough for underwater operations.

The robot, which measures nearly five meters in length and weighs about 350 kilograms, is designed to faithfully replicate the movements of a real whale shark. This creation is the result of a complex design that required the integration of advanced technologies typical of the aerospace industry. The robot’s ability to swim, turn, float, dive up to 20 meters deep and move its mouth make it an extremely versatile tool, with speeds of up to 0.7 meters per second.

Gao Chao, lead engineer of the project, explained that the main challenge was the development of seven implemented joints, each requiring a sophisticated computing, communication and sensing system. This multi-joint system gives the robot an innovative bionic propulsion, capable of improving swimming efficiency compared to conventional underwater robots.

In addition to its impressive mechanical engineering, the robotic whale shark is equipped with a number of cutting-edge technologies. These include advanced optical cameras, sensors, and a BeiDou satellite positioning system, enabling it to perform a variety of tasks such as monitoring water quality and mapping the seafloor. Another distinguishing feature is wireless remote control, which enables remote operations and programmed swimming.

A particularly relevant aspect of this project is its focus on environmental sustainability. The robot’s enclosed design reduces the risk of water contamination, limiting the release of pollutants. In addition, the aerodynamic body of the robot is designed to minimize the risk of getting stuck in underwater obstacles and to reduce damage to surrounding marine life.

The introduction of the robotic whale shark not only represents an important technological breakthrough, but also marks the beginning of a new development phase for Shenyang Aerospace Xinguang Group. Indeed, the company plans to expand its range of bionic robots to include models inspired by different marine species such as dolphins, killer whales, and even the Yangtze River porpoise. These developments could have significant implications for both scientific research and maritime operations.


The advance represented by the robotic whale shark reflects the growing role of bionics in underwater operations, opening up new possibilities for marine research and industry.
