China has showcased a highly realistic fish-shaped underwater robot that can autonomously navigate through water, highlighting the country's growing development of biomimetic robotic systems with potential applications in underwater surveillance and reconnaissance.According to Chinese news outlet Jimu News, BG-5 Golden Dragon Fish, developed by Boyagongdao Marine Technology Group, was demonstrated at the 2026 China International Fair for Trade in Services (CIFTIS) in Beijing's Shougang Park. The robot is modelled on the golden arowana and uses a multi-joint tail to reproduce the swimming motion of a real fish.Jimu News quoted an exhibition staff member as saying that the robot does not follow a pre-programmed swimming route. Instead, its sensors detect obstacles and allow it to autonomously plan its movement.
