Underwater robots are being widely used as tools in a variety of marine tasks. The RobDact is one such bionic underwater vehicle, inspired by a fish called Dactylopteridae known for its enlarged pectoral fins. A research team has combined computational fluid dynamics and a force measurement experiment to study the RobDact, creating an accurate hydrodynamic model of the RobDact that allows them to better control the vehicle. The team published their findings in Cyborg and Bionic Systems on May 31, 2022. Underwater robots are now used for many marine tasks, including in the fishery industry, underwater exploration, and mapping. Most...
