Hiroshima engineers develop robotic carp

Koi robotRyomei Engineering (a subsidiary of Mitsubishi Heavy Industries), 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.

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.

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.

  1. […] Finally a Robot Carp to add to my collection of murderous spybots (insert evil laugh here ). Actually this robot ( being as silly looking as it is ) is actually very useful and is designed to do things like test water quality and swim around like a normal fish takeing pictures of the under-water-world. Designed by Ryomei Engineering you can get that more info from Pinktentacle Website. […]

    I’m sorry. I think it’s really cool that robotics has advanced to this level, but this is definitely on the far side of the Uncanny Valley. Looking at it just creeps me out on a very visceral level.

    …. The autonomous robot pigs are part of a cost-effective, evironmentally friendly, solar drying process for sewage plants. Sewage is spread over a large area where it absorbs the sun’s heat, causing evaporation of water, which lowers the mass of the sewage. The robot pigs assist by constanly churning the sewage. …more…

    But can you flush it?

    i have several koi in a tank in my house. The biggest is about 8 inches. I can tell you with much certainty, non-robotic koi can indeed swin backward. not for long periods of time, but they do it to position themselves for feeding and the maneuver within and around crowds.

  34. “Robo-carp” rehearses for public debut 

    The robotic koi carp unveiled last month by a group of Hiroshima engineering companies (led by Ryomei Engineering) is scheduled to make its first public appearance this weekend.

    It was spotted during rehearsal in a large tank at Miyajima Aquarium (in Hatsukaichi city in Hiroshima prefecture), practicing its trademark moves of spinning around, treading water, and swimming in reverse. The robot appeared to be getting along will with the other fish in the tank — an alligator gar and three endangered pirarucu that measure over 2 meters in length.

    “It looks like a robot, but it behaves like a real fish,” said one surprised onlooker.

    Public demonstrations of the robot will be held at the aquarium this weekend (April 15 - 16).
