Ryomei Engineering, in cooperation with two other Hiroshima-area engineering companies, has developed a robot resembling a koi carp. The robot was demonstrated at a pond on the grounds of Hiroshima Machinery Works, Mitsubishi Heavy Industries.
The robot is modeled after a Nishiki koi carp as a form of tribute to Hiroshima Castle (whose nickname Ri-jo means Koi Castle). The 80-cm (31-inch), 12-kg (26-pound) fish has a white body with bright red spots. Though the tail movement is very smooth and lifelike, the remote-controlled koi is capable of moves that a genuine koi is unable to perform, such as swimming in reverse and rotating in place.
