| Abstract: | Weakly electric knifefish have intrigued both biologists and engineers for decades with their unique electrosensory system andagile swimming mechanics. Study of these fish has resulted in models that illuminate the principles behind their electrosensorysystem and unique swimming abilities. These models have uncovered the mechanisms by which knifefish generate thrust forswimming forward and backward, hovering, and heaving dorsally using a ventral elongated median fin. Engineered activeelectrosensory models inspired by electric fish allow for close-range sensing in turbid waters where other sensing modalities fail.Artificial electrosense is capable of aiding navigation, detection and discrimination of objects, and mapping the environment, alltasks for which the fish use electrosense extensively. While robotic ribbon fin and artificial electrosense research has beenpursued separately to reduce complications that arise when they are combined, electric fish have succeeded in their ecologicalniche through close coupling of their sensing and mechanical systems. Future integration of electrosense and ribbon fintechnology into a knifefish robot should likewise result in a vehicle capable of navigating complex 3D geometries unreachablewith current underwater vehicles, as well as provide insights into how to design mobile robots that integrate high bandwidthsensing with highly responsive multidirectional movement. |
