The Analysis of Possibility of Using Electromagnetic Drive for Autonomous Biomimetic Underwater Vehicle

Abstract

Striving for a perfect imitation of fish motion is one of assumptions of building autonomous biomimetic underwater vehicle. Usage of typical servomechanisms gives good results, but it is important to eliminate their two main disadvantages: large power consumption and constant torque in whole range of motion. In the paper, an analysis of possibilities of using set consisting of a permanent magnet and an induction coil for electromagnetic drive of the vehicle was included. Values of driving torque and character of its change in comparison with muscle system of fish were estimated.
