Fish Sensor

A research team led by Chang Liu at the University of Illinois at Urbana-Champaign (UIUC, Champaign, IL) has built a sensor for underwater vehicles equivalent to a sensory organ found on fish called the lateral line. In fish, the lateral line provides guidance for synchronized swimming, obstacle avoidance, and prey/predator detection...
