- An Artificial Lateral Line (ALL) is a biomimetic lateral line system. A lateral line is a system of sensory organs in aquatic animals such as fish, that serves to detect movement, vibration, and pressure gradients in their environment. An artificial lateral line is an artificial biomimetic array of distinct mechanosensory transducers that, similarly, permits the formation of a spatial-temporal image of the sources in immediate vicinity based on hydrodynamic signatures; the purpose is to assist in obstacle avoidance and object tracking.... The biomimetic lateral line system has the potential to improve navigation in Under-water Vehicles when vision is partially or fully compromised. Under-water navigation is challenging due to the rapid attenuation of radio frequency and Global Positioning System signals. In addition ALL system can overcome some of the drawbacks in traditional localization techniques like SONAR and optical imaging. The basic component of either a natural or artificial lateral line is a neuromast, a mechanoreceptive organ that allows the sensing of mechanical changes in water. Hair cell serves as the basic unit in flow and acoustic sensing. Some species like arthropods use a single hair cell for this function and other creatures like fish use a bundle of hair cells to achieve pointwise sensing. The fish lateral line consists of thousands of hair cells. In fishe, a neuromast is a fine hair-like structure that uses transduction of rate coding to transmit the directionality of the signal. Each neuromast has a direction of maximum sensitivity providing directionality. (en)
