RoboCarp Underwater Vehicle Swims Like a Real Fish

A team of researchers has developed a robot fish that imitates the movements of a carp. They're from the Department of Electrical and Computer Engineering at the National University of Singapore (NUS), and they're calling their invention, of course, RoboCarp.

The robotic fish, or autonomous underwater vehicle (AUV), is about five feet long, weighs 22 pounds and can dive to six feet. The technology uses an internal ballast system that enables the drone to dive and float like a real fish

Said Professor Xu Jianxin, part of the research team, "Currently, robot fish capable of 2D movements are common, meaning that these models are not able to dive into the water. Our model is capabe of 3D movements as it can dive and float, using its fins like a real fish."
