A team of Israeli scientists has taught goldfish to maneuver a robotic car. The fish were trained to reach a target at the opposite end of a room in return for a fish food reward — something they could do repeatedly, even with obstacles in their way.
An old joke goes like this: Two fish are in a tank and one says,"Do you know how to drive this thing?"A team from Ben-Gurion University has successfully taught goldfish to maneuver a robotic car on land, via a top-down camera that monitors their movements around a small fish tank.The camera in the “fish-operated vehicle” uses motion sensing technology to send a signal to one of its four wheels whenever a fish swims close to a side of the fish tank.
A researcher prepares a goldfish to learn how to navigate with a fish-operated vehicle on land, at Ben-Gurion University in Beersheba, Israel., shows that the navigational abilities of fish stay intact in a land-based environment. And for one of its authors, this shows that humans and fish may not be quite as different as some think.
"It's not that fish are primitive, they just developed in a very different world from us. They need to solve sophisticated [problems] to exist in their environment."
