The current trends in the creation of underwater robotic devices for the study of the world ocean are considered. It is noted that complex types of motion of various effectors cannot be implemented by means of simple electromechanical transducers. Therefore, the use of genetic engineering techniques to create a variety of electromechanical structures that can provide effective functionality of marine robotics objects solves a scientific problem that is of much current interest.The aim of this work is to analyze and study the possibility of applying the principles of genetic synthesis for the development of new types of energy-efficient transducers built on the basis of complex electromechanical structures and demanded by a wide range of the developing marine robotics.It is shown how complex electromechanical structures that satisfy a given target function are obtained using genetic operators, together with operators of geometric transformations. The use of genetic engineering techniques for the development of electromechanical transducers expands the possibilities of creating and studying the structural diversity of mechanisms with complex movement of effectors. The configuration of a wave fin propulsion device based on the inductor electromechanical transducer of axial-radial configuration is considered.A mathematical model, methods and a program for calculating an electromechanical transducer with complex structural axial-radial configuration is developed. The problem of determining the optimal copper/steel ratio is solved, the leading dimensions are obtained and the rational relations of the parameters for calculation of the axial-radial configuration transducer with a minimum mass are established.

A systematic approach to the design of electrical machines is implemented by solving problems of analysis and synthesis in various combinations at different stages and stages of design. The questions of the formulation and implementation of synthesis and analysis problems in the study and design of modular-type magnetically commutated electrical machines are considered. They are aimed at reducing weight, size and cost while improving the performance of these newly designed machines. A complex method of parametric synthesis and an automated program containing a calculated mathematical model of an electric machine has been developed. On the basis of numerical full factorial experiments, the optimization parameter is determined, and a regression analysis is performed with the construction of an optimization model. It allows you to find a narrow range of variation of significant factors, at which the optimization parameter satisfies the specified conditions. On the example of studying an inductor generator of axial-radial configuration, new approaches to the formulation and solution of typical problems of analysis and synthesis of modular-type electrical machines are shown. The use of complex parametric synthesis makes it possible to significantly reduce the masses of the designed modular machines in comparison with drum-type inductor machines of the same power.
