  In this paper, a new neuronal circuit, based on the spiking neuronal network
model, is proposed in order to detect the movement direction of dynamic objects
wandering around cognitive robots. Capability of our new approach in
bi-directional movement detection is beholden to its symmetric configuration of
the proposed circuit. With due attention to magnificence of handling of
blocking problems in neuronal networks such as epilepsy, mounting both
excitatory and inhibitory stimuli has been taken into account. Investigations
upon applied implementation of aforementioned strategy on PIONEER cognitive
robot reveals that the strategy leads to alleviation of potential level in the
sensory networks. Furthermore, investigation on intrinsic delay of the circuit
reveals not only the noticeable switching rate which could be acquired but the
high-efficient coupling of the circuit with the other high-speed ones.
