Mathematical Modelling and Feasibility Study ofthe Biomimetic Undulating Fin of a Knife Fish Robot

Meera A. A., Sudheer A. P.

Journal of Automation Mobile Robotics and Intelligent Systems

17--25

Bio-mimetic underwater robotics is an emerging area of research, which has the potential to substitute the conventional energy inefficient mode of underwater propulsion using thrusters. In this paper, the mathematical modelling of the undulating fin is done and the effect of various parameters of the mechanism design on the available workspace is studied. The mathematical beauty is revealed, for the curves representing the mechanical constraint and the family of undulating waves. The feasibility of a wave to be generated by the mechanism was analyzed.

Design Optimization of the Biomimetic Undulating Fin of a Knife Fish Robot

Median Paired Fin Propulsion used by fishes like knife fish, has the potential to replace current energy inefficient underwater propulsion systems. This paper quantizes the efficiency of a fin mechanism based on its ability to incorporate a large number of undulations. Characteristic ellipses of a mechanism were defined, based on which two algorithms were defined to measure the capabilities of the mechanism. The available workspace of the mechanism was optimized to accommodate the undulation requirements of the robot based on the formulations. Further, the distortion effect on the waveform was identified and the optimization was redefined to obviate its possibility while in operation.
