A Lifelike Robotic Penguin Swims Right Beside Real Penguins

本物そっくりのペンギンロボ=動物園で人気者に―和歌山
At Adventure World in Wakayama, a robotic penguin swims beside real penguins, moving its flippers to turn and dive.
The robot was built by the park operator’s Kokorobo team. The result is a zoo exhibit where a machine can briefly blend in with the animals people came to see.

A zoo exhibit quietly turning into a “spot the robot” puzzle is a wonderfully unexpected side effect of getting the engineering right.
