  "account": "China has unveiled a fish-shaped autonomous underwater robot at the 2026 China International Fair for Trade in Services in Beijing. The BG-5 Golden Dragon Fish biomimetic navigation technology could support various inspection, environmental monitoring, search, and defense-related missions. This robot was developed by Boyagongdao Marine Technology Group and is designed to resemble a golden arowana. The robotic fish propels itself through water using a flexible, multi-joint tail, allowing for autonomous obstacle detection and route adjustment, unlike conventional vehicles that follow pre-programmed paths. The BG-5 is 640 millimeters long, weighs about 3 kilograms, and can operate at a maximum depth of 5 meters with a top speed of 0.6 meters per second. Equipped with infrared recognition for autonomous obstacle avoidance and wireless communication for online debugging and control, the robot can perform global and local path planning, task allocation, formation control, cooperative transport, and coordinated operations involving multiple robots. Its applications extend beyond the single demonstration unit, potentially dividing underwater areas for inspection or monitoring, maintaining formations, and coordinating tasks in challenging environments. While the robot's military deployment remains unconfirmed, its capabilities align with reconnaissance or monitoring applications. Boyagongdao Marine Technology Group has a decade-long research background with Peking University's College of Engineering, focusing on high-speed biomimetic drive mechanisms and central pattern generator control algorithms to replicate the smooth movement of aquatic animals. The BG-5 is not a newly created model, as the company had previously displayed a similar robotic fish at other exhibitions. However, the latest CIFTIS appearance garnered renewed attention due to its autonomous obstacle avoidance and more realistic biomimetic movement. China's underwater robotics efforts extend beyond fish-shaped machines, with various autonomous systems being developed for coral monitoring, infrastructure inspection, marine ranching, emergency rescue, and deep-sea research. Some platforms are equipped with cameras, sonar, or environmental sensors, while others utilize robotic arms for intervention tasks.",
