\"China
Crowds in Hall 3 at Beijing\u2019s Shougang Park last week kept stopping at a small tank. A slender golden fish with layered scales was rising, sinking, and turning with a soft flick of its tail. Only after it changed course on its own did most people accept they were watching a machine, not an arowana that had wandered into a trade-fair display.<\/p>\n

Boyagongdao Marine Technology Group debuted the BG-5 Golden Dragon Fish at the 2026 China International Fair for Trade in Services, and it was a huge hit. The robot is essentially a replica of the arowana\u2019s long body and glossy gold coloring, down to the details. According to the catalogue\u2019s specifications, it is 640 millimeters long, 204 millimeters wide, and 90 millimeters high, weighing around 3 kilograms. It is supposed to be capable of operating at depths of up to 5 meters and reaching speeds of up to 0.6 meters per second.<\/p>\n

    \nAccording to those working on the exhibit, the fish was not programmed with a predetermined course; instead, the robot\u2019s onboard sensors detect its surroundings and plans a new path as it goes. That\u2019s kind of the purpose; canals, lakes, and tunnels change all the time, and a human operator just cannot keep up with every twist and turn.<\/p>\n

    The propulsion system is quite interesting, as it is a flexible tail with three joints divided into seven segments that work together to send a wave down the fish\u2019s body, just like a real fish. There are no spinning propellers, so it\u2019s much quieter and less noticeable than your usual underwater drone. All of the electronics are safely stored in the main cabin, which includes all of the high-precision sensors and a fancy global vision control system you\u2019d expect for a task like this, as well as a modular layout to make servicing easy.<\/p>\n
