This Goldfish Controls A Robotic Tank with its Movement

Interesting Engineering

Watch as this goldfish controls a robotic tank with its movement. The goldfish determines the speed and direction of the robot by varying its position in relation to the middle of the fish tank. A group of friends have developed the invention for Build18, an annual engineering festival organized by Carnegie Mellon University. They build the robot in just three days.

“We were sitting around one day trying to think of project ideas when we looked at the Fish in our Fraternity house, Walter, and decided it would be awesome if he could hang out with us!" said Zachary Newman, one of the inventors. "From there, coming up with a design was pretty simple."
