We proposed in this study the circuit and network for detecting the approaching object based on the visual systems of the pigeon and the locust. The proposed circuit and network became simple structure. The circuit and network were evaluated by the simulation program with integrated circuit emphasis (SPICE). The circuit based on the visual system of the pigeon output the signal which is proportional to the time to collision. The circuit and network based on the locust vision system generated the signal for avoiding the collision of the object. It was clarified from the simulation results that the proposed simple circuit and network can detect the time to collision, the size and the velocity of the approaching object.
