Robot Koi
Today is shaping up to be aquatic robot day, so it’s fitting that Pink Tentacle brings us an article about a robot built by Ryomei Engineering that is modeled after a koi carp. At 31 inches long and 26 pounds, the robotic koi can swim like the real thing plus do some things its inspiration can’t, like swimming backwards and rotating in place. It is controlled by wireless remote, has a camera in its head and built-in sensors for testing water quality. The koi is not the first aquatic robot Ryomei Engineering has produced. Other iterations include a sea bream and prehistoric coelacanth.

The narration is in Japanese, but the footage is compelling regardless.
