Roland Piquepaille writes, "Today, both submarine and surface ships
use sonar for navigation. But sonar and other vision systems face
various limitations. So why not imitate fish? For millions of years,
fish have relied on 'a row of specialized sensory organs along the sides
of their bodies, called the lateral line' to avoid predators or find
prey. So engineers at the University of Illinois at Urbana-Champaign
(UIUC) have decided to build an
artificial lateral line for submarines and autonomous underwater
vehicles (AUVs). The first tests have been successful, and we can now
envision a day where AUVs could detect and track moving underwater
targets or avoid collisions with moving or stationary objects." For
more details on the story, see Roland's blog. If
you're interested in technical details of the sensors itself, check out

hydrodynamic imaging with an artificial lateral line (PDF format).
