AbstractThis paper deals with maneuver issues, in particular turning control of a free-swimming, multi-link biomimetic robotic fish propelled by a flexible rear body and oscillatory tail fin. Taking into account of both hydrodynamic model and engineering use, we develop a practical method to execute a circular maneuver. The turning control, based on asymmetrical kinematics and dynamics, can be achieved by adding different deflections to the oscillatory links. The characteristic parameters affecting turning performance include magnitude, position, and time of the deflections applied to the links, which are discussed with a series of simulation calculations. The experiments of circular motion with a four-link, infrared-sensor-equipped robotic fish acquire a satisfactory maneuverability. Moreover, the feasibility of adding deflection angles to maneuver the robotic fish in the path planning is explored both analytically and experimentally.
