Golden robot fish goes viral

A robotic golden arowana made by Boyagongdao Marine Technology Group became one of the most shared clips from China International Fair for Trade in Services at Beijing's Shougang Park this month.
What the BG-5 can do
The three kilogram, six hundred forty millimetre robot operates at a maximum depth of five metres with a top speed of zero point six metres per second, or approximately two point one six kilometres per hour.
Specs kept under wraps
Boyagongdao has not published endurance, payload, or camera specifics, and it has not made any battery-life figures public, despite the robot's surveillance capabilities.
Not a new design

The BG-5 is not new. Its product page carries images uploaded in August twenty twenty-three, and the company used it to illustrate a World Oceans Day post in June twenty twenty-three.
Military focus is clear
Boyagongdao describes itself as a military-civil fusion enterprise, pitching its bionic robo-shark as a quiet platform with a sound-absorbing shell for concealment and its robo-ROV for underwater combat tasks.
Company confirms military use
A company representative, Zhang Yu, said in a twenty twenty-five report its bionic technology can also be used in military and national defense fields.
“can also be used in military and national defense fields”
Anti-poaching potential
The golden arowana is an endangered species left vulnerable by over-harvesting for the aquarium trade. A surveillance fish lookalike could deter fishermen from attempting to catch the protected species.
Undisclosed specs suggest single buyer
The relatively suspicious exclusion of hardware internals, capabilities, and endurance figures suggests the BG-5 may be aiming to cater to a single primary customer, despite the company's insistence on multiple use cases.
What matters most
A robotic golden arowana fish displayed at China's trade fair has gone viral for its autonomous underwater surveillance capabilities, though the company has military applications in mind.
