Amouse: the mouse-whisker cyborg that's mostly robot & a little bit rat
The Artificial Mouse Project (Amouse) is a European project to develop a multisensory robot with visual sensors and an artificial whisker system. The organic component of this thing is a robot built with rat whiskers glued on capacitor microphones.
"Each whisker is thus a single sensor. Data acquisition is done on a laptop with a PCMCIA data acquisition card.
So far, the artificial mouse has been used for experiments on the morphology of the whisker array. We looked for an optimal arrangement of the whiskers by comparing different morphologies as to how well the robot was able to avoid obstacles. We found that a different morphology than the one found in nature is optimal for this task."
