Target tracking system using analog circuit for motion detection

A simple analog circuit for motion detection was previously proposed based on the biological vision system. In this study, simple analog circuits and system for tracking an object (target) was proposed and fabricated by applying the previous proposed motion detection circuits to the first stage. The circuit for tracking the target was fabricated on the printed board by using discrete metal oxide semiconductor (MOS) transistors. The circuit could output the voltage for controlling the motor utilized to the target tracking system. The developed system could track the target and capture the target on the center of the input part. The realization of the compact visual sensor for the robotics and monitoring system can be expected by applying the proposed circuits and system.
