Docking System With Video Feedback

Abstract

Video-sensor/electronic-feedback control system being developed to provide automatic control of final stage of approach of active vehicle to passive vehicle or object. No communication between vehicles necessary. Docking target, mounted on post on passive vehicle, has three reflective dots, positions of which measured in image to determine relative position and orientation of target and vehicle. Control channels process video-sensor feedback into motion-control signals (thrustor commands in spacecraft or motor commands in robot). Conceived for use aboard chasing spacecraft to control its maneuvers in docking with chased spacecraft, concept also useful in controlling coupling of aircraft in flight or vessels on water or in controlling approach of robot to object to be manipulated.
