Hackaday told some days ago that a machine vision company Studio diip based in The Netherlands has created an interesting fish on wheels, a robotic car controlled by a goldfish. The system appears to work pretty well on the video. This is quite funny looking system.
A Logitech 9X0 series camera captures overhead images of the fish tank and the images are then fed into a BeagleBoard XM, where they are processed. The BeagleBoard can determine the fish’s swim direction and commands the chassis to drive accordingly.
The idea of giving fish mobility on land is nothing new, but this definitely is a novel implementation.
