Abstract
Abstract The major interest of this article is to investigate a single and an array of mechanical arms driven by Josephson junction (JJ) circuits and their applications in mimicking the locomotion of myriapods. Stability analysis of a single mechanical arm driven by a JJ circuit resulted in two equilibrium points and a switch of their stability for specific values of the stimulation current. Results of the numerical simulations reproduce the motion of myriapods in agreement with existing results and the proposed electromechanical system overcomes the difficulties of coupling many JJ circuits or other models of neuron circuits in actuating a single mechanical arm for mimicking the locomotion of myriapods. Actuation of the mechanical arm driven by a JJ circuit is confirmed by numerical simulations which are sensitive to the action of the electromagnetic signal and the effect of mass. The progressive excitation of the mechanical arms of the array of the electromechanical system as demonstrated by the numerical simulations is similar to the straightforward motion of myriapods.
