China's Robot Fish: Spy or Eco-Warrior?
20 Sep
Summary
- A robotic golden arowana named BG-5 acts as an autonomous underwater surveillance drone.
- The 3 kg robot can operate at 5 meters depth with a 0.6 m/s top speed.
- The company has military applications for its bionic robots, including underwater combat.
A robotic golden arowana, the BG-5 by Boyagongdao Marine Technology Group, gained significant attention at CIFTIS 2026 in Beijing for its lifelike appearance and autonomous navigation. This 640 mm, 3 kg robot is designed to function as an underwater surveillance drone, capable of operating at depths up to 5 meters and reaching speeds of 0.6 m/s. While details on its endurance, camera capabilities, and payload remain undisclosed, the BG-5 is not a new development, with the company showcasing similar arowana robots since 2021.
Boyagongdao openly markets its bionic technology for military applications, with one representative stating its use in "military and national defense fields." The company has previously pitched its ROBO-SHARK and ROBO-ROV for tasks including underwater combat. This military focus, coupled with the exclusion of detailed hardware specifications, suggests a primary customer in the defense sector, despite claims of broader applications in education, research, and marine biology. Ironically, the robot's appearance could also serve as an anti-poaching tool for endangered Asian arowana.
The BG-5's design builds upon earlier versions, including the ROBOLAB-GL introduced around 2021. The company's self-identification as a "military-civil fusion enterprise" underscores the potential dual-use nature of its bionic aquatic robots. The recent viral spread of the BG-5's footage highlights public fascination with its advanced capabilities and lifelike design.
