Something attention-grabbing swam throughout my Twitter feed lately: a video of a goldfish that appeared to be controlling a robotic fish tank with wheels, with the contraption following the path the fish was swimming. “Oh no,” I thought. “They gave this goldfish a robot, and now it’s unstoppable.”
Thankfully, it doesn’t appear to be it was achieved as part of some evil plot. The goldfish mech go well with was posted by Ronen Segev, a researcher on a workforce that was wanting into how animals navigate. Helpfully, Segev hyperlinks to a full analysis paper in the Twitter thread, which ought to supply extra perception into the venture.
The fish have been tasked to “drive” the car in direction of a visible goal in the terrestrial setting, which was observable by way of the partitions of the tank. Indeed, the goldfish have been in a position to discover the terrestrial setting, all whereas avoiding dead-ends and correcting inaccuracies. pic.twitter.com/RxPuzFbxkE

The paper is formally titled “From fish out of water to new insights on navigation mechanisms in animals,” and its summary describes why the researchers “trained goldfish to use a Fish Operated Vehicle (FOV).” They needed to check its capability to do one thing acquainted, navigating in direction of a goal in an unfamiliar setting — on this case, land. To do that, the researchers tracked the fish’s actions with LIDAR, which let it “drive” in direction of a goal that it may see outdoors of its tank.
Returning to the Twitter thread, although, a remark caught my eye — no, not the joke about The Umbrella Academy’s Carmichael, although it did get amusing out of me. It was a remark about how another person had constructed a really related contraption. In 2014, Studio diip launched a video known as Fish on Wheels, which was meant to exhibit pc imaginative and prescient tech. If you’ve watched Segev’s video, Fish on Wheels will appear fairly acquainted; there’s a fish tank on wheels with a sensor that tracks the fish’s motion to steer the car. (Can we name it a car? Sure, why not.) Basically, Fish on Wheels is the identical concept however constructed for a distinct purpose.
That’s when I began falling down the rabbit gap. Looking into Fish on Wheels led me to a 3rd goldfish Gundam, this one made as a part of Carnegie Mellon University’s Build18 engineering pageant, in accordance to a video posted of the venture in 2017. According to Interesting Engineering, the robotic was in-built three days by college students who “decided it would be awesome if he [the fish, named Walter] could hang out with us!” You can see the end result beneath.
And guess what — shopping a Reddit thread about that venture unearthed yet one more one that made robotic fish bowls. This one was a 2004 artwork set up by Ken Rinaldo known as “Augmented Fish Reality.” It featured 5 robots managed by betta fish and was “designed to explore interspecies and trans-species communication,” in accordance to Rinaldo’s web site. Are there examples from even additional again that I haven’t discovered? How do folks preserve doing the identical factor however seemingly for utterly totally different causes?
And after watching all these touring fish, there’s one factor that I completely, desperately want to know: what would my cat do if he noticed a goldfish rolling by in a robotic tank?
