Watch: China unveils robotic fish modelled on the golden arowana for underwater navigation

China’s BG-5 Golden Dragon Fish biomimetic underwater robot showcased at CIFTIS in Beijing. 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. Its small 3-kg form factor could allow it to operate in confined or shallow underwater environments where larger unmanned underwater vehicles may be less practical. Its fish-like, multi-joint propulsion could support low-profile underwater surveillance.Its BG-5V variant with its path planning, task allocation, formation control and multi-robot coordination, potentially enabling multiple underwater robots to conduct coordinated search, surveillance and reconnaissance missions.
