Today I learned about the attempts to make goldfish mech suits

The image is called "chorus image" and it can be found on

The robot is following the fish.

A video of a goldfish that seemed to be controlling a robotic fish tank with wheels, with the contraption following the direction the fish was swimming, was found on my feed. I thought. The goldfish was given a robot.

It doesn't seem like it was done as part of an evil plot. The researcher on the team that was looking into how animals navigate posted a goldfish suit. The full research paper can be found in the thread on the project.

The fish were tasked to drive the vehicle towards a visual target in the ground, which was visible through the walls of the tank. The goldfish were able to explore the environment, all while avoiding dead-ends.

The paper is titled "From fish out of water to new insights on navigation mechanisms in animals", and the abstract describes why the researchers "trained goldfish to use a Fish Operated Vehicle (FOV)." They wanted to see if it could navigate towards a target in an unfamiliar environment. The researchers were able to see a target that the fish could not see in its tank with the help of LIDAR.

The comment that caught my eye was not the joke about The Umbrella Academy's Carmichael, but it did get a laugh out of me. Someone commented on how someone else had built a similar contraption. The video was supposed to show off computer vision tech. If you watched the video, you will know that there is a fish tank on wheels with a sensor that tracks the fish's movement to steer the vehicle. Can we call it a vehicle? Yes, why not. Fish on Wheels is a different idea than the one it is based on.

I fell down the rabbit hole. I was led to a third goldfish by looking into Fish on Wheels, which was part of the engineering festival at Carnegie Mellon University. The robot was built in three days by students who decided it would be awesome if Walter could hang out with us. The result is shown below.

A person who made robotic fish bowls was discovered by browsing a thread about that project. Ken Rinaldo did an art installation called "Augmented Fish Reality" in 2004. It featured five betta fish-controlled robots that were designed to explore interspecies and trans-species communication. I haven't found any examples from further back. How do people keep doing the same thing?

I need to know what my cat would do if he saw a goldfish rolling by in a robotic tank, after watching all these traveling fish.
