Robot Koi Carp

A robot fish from a consortium of Hiroshima, Japan engineering companies.
From Pink Tentacle:
"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 smooth tail movements closely resemble those of a real fish, 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."


"The robot is Ryomei Engineering’s fifth in a line of fish robots that includes a sea bream, a prehistoric coelacanth, and a golden carp. New features added to the robotic koi include a CCD camera built into the head and sensors for analyzing water quality."
