Blind cave fish inspires sensing system for autonomous underwater vehicles

RATE THIS! +6
Posted in Science on 17th Dec, 2012 11:46 PM by AlexMuller

Ever wonder how fish can find their way around so easily in murky water? Well, most of them use something called their lateral line – a row of hair cells down either side of their body that detect changes in water pressure caused by movement, or by water flowing around objects. Now, scientists from Singapore’s Nanyang Technological University and MIT have copied the lateral lines of the blind cave fish, in a man-made system designed to allow autonomous underwater vehicles (AUVs) to navigate more accurately and efficiently.

 

Ordinarily, AUVs use cameras, sonar, or an underwater acoustic positioning system. Cameras aren’t much use in murky water, however – and a lot of the world’s water bodies are murky. Sonar and acoustics are better in such situations, but the hardware can be expensive, and taxing on the AUV’s batteries.

 

By contrast, the blind cave fish-inspired sensors can reportedly be made for under US$100 per array, and use little power. Additionally, they don’t produce audible sonar “pings” that can be harmful to aquatic animals.
