How fish sensory organs could improve underwater robots’ navigation skills

These researchers think these same cues could be used in swarms of underwater robots. The team’s research is focused on the lateral line sensing organ found in African cichlid fish, but it can also be found in most fish species. This lateral line-sensing organ helps the fish sense and interpret water pressures around them. These organs are sensitive enough to detect external influences, like neighboring fish, changes in water flow, nearby predators and obstacles. On fish, the lateral line system is distributed across the head, trunk and tail of the fish. It is made up of mechanoreceptors, or lateral line sensory units called neuromasts that are either withi...
