Abstract

The invention discloses an application of a memristor with a non-monotonic change resistance state in collision prediction. The material of a dielectric layer of the memristor is a dielectric material capable of being regulated and controlled by light. Under the stimulation of optical signals, the resistance state of the memristor presents non-monotonic change. The memristor has electrical responsiveness to light intensity, dynamic regulation and control of the resistance state of the memristor are achieved by changing the geometrical shape of the CF through transient Joule heat generated by illumination, and therefore the distance of a moving light source is recognized, and the impending collision behavior is predicted. Sensing and processing of optical signals are effectively integrated in a single memristor, and a series of problems caused by a complex computing system of an existing mobile robot are solved. Besides, the collision prediction method constructed based on the Joule thermal effect of the memristor has the advantages of low cost, high stability, simplicity in operation and the like, so that the collision prediction method has a good application prospect and can be widely applied to intelligent collision prediction of a mobile robot system.
