Abstract:
The invention relates to a new method for the control of movement which takes its idea from the principles on which the movement of certain biological organisms are founded. The proposed approach also permits the development of robotic architecture equipped with a revolutionary analogic system of locomotion, inspired by biological walking. The circuital embodiment of such system of locomotion is made concrete with the possibility of circuitally implementing a model of equations of the reaction diffusion type capable of generating, for certain combinations of parameters, initial conditions and boundary conditions, signals of auto-wave or spatial pattern type for the control of movement.
Abstract:
A chaotic-signal generator comprises a set of elements (1 to 4) for generating signals, which are connected together according to a scheme of chaotic dynamics of signal generation. The connection scheme may advantageously correspond to the circuit generally referred to as Chua's circuit, in particular in its possible implementation as a cellular neural network (CNN). Interposed in the aforementioned connection scheme is at least one switch (5), such as a MOS transistor, the opening and closing of which causes the variation in the chaotic dynamics of signal generation. The opening and closing command signal (u(t)) applied to the aforesaid switch (5) may therefore be made to correspond to a modulating signal in view of transmission on a channel, such as a high-noise channel. In a particularly preferred application, the aforementioned modulating signal is a binary signal, and the aforementioned opening and closing command signal is constituted by a switching signal, the switching frequency of which is caused respectively to increase or decrease depending on the logic level assumed by the modulating signal.
