Abstract

Approaching object detector structure has been recently identified in mouse retina, and its neural circuit model has been successfully built. A discrete-type mathematical model describing the retinal structure has been synthesized and implemented on a biologically motivated focal-plane mixed-signal sensor-processor device. The model responses have been analyzed, and the critical parameters have been identified, and their roles were studied. The model has been validated in real dynamic surround of a robotic arm, where the geometrical and the kinematic parameters of the movements were known. From the mathematical and experimental analysis, it has been concluded that this retinal structure has a capacity to generate a last second warning signal to avoid collisions.
