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.
