Watch these goldfish learn to drive
Scientists in Israel have taught goldfish how to DRIVE. They strapped a fish tank to a little car, and a special camera tracked the fish. So the car would move in any direction it swam in. After a few days, it was able to drive the car in a straight line across a room to a specific target, where it could get food..
They wanted to see if fish could learn to navigate on land. So they built a small, robotic vehicle with a fish tank on it. And they put wheels on the bottom, so it could move in any direction. They called it an "F.O.V." or "Fish Operated Vehicle."
A special camera on top tracked how the fish moved, and translated it into directions for the little fish-car they were in. So if they swam toward one side of the tank, the whole thing would go that direction at about one mile per hour.
Next, they put it in a room with a big target on one of the walls. And if it could make it to the target, they'd reward it with food.
It took the goldfish a few days to learn how. But they eventually got pretty good at driving, and could basically do a straight line right to the target. Researchers ultimately taught six different goldfish to drive, so it wasn't a fluke.
They say the point of the study was to learn more about how our brains navigate terrain we're not used to.
They also wanted to see if fish are smart enough to learn complex tasks like that, and it looks like they are.
