An ultra-realistic underwater drone modelled after the arowana fish has been getting a lot of attention online, after making its debut at a military expo earlier this month.
This year’s Beijing Military Expo opened on June 5th, but it wasn’t the tanks, missiles, and other potentially lethal military equipment that drew reporters’ attention, it was a rather strange arowana fish swimming in a large water tank installed on site. At first glance, it was just a fish that seemed to swim and behave normally. It would swim around normally, and raise its head for a while whenever it reached a wall, then just wing its tail again and swim in another direction. At first glance, its appearance and movements were those of an actual fish, and it was only on close inspection that one realized this was an advanced fish-like robot.
